As a millwright, experienced in dealing with bearings for many, many years, I can tell you that removing the seals on a factory sealed bearing is entirely wrong. They are lubricated with the exact amount of grease, and as long as the seals are in good shape it’s far better to leave them alone. Once you remove a seal, grease can enter, but so can contaminants. Too much grease will cause overheating and shorten the life of the bearing. For a mower deck, check the spindles annually and replace any worn bearings with sealed bearings. Forget about the Zirk fitting, pumping grease in there won’t do anything to prevent damage. If you remove the inside seals on these bearings and pump the housing full of grease, you may put too much in and dislodge the outer seals, and then you’ll destroy both bearings.

This comment is not to help you but for the third party that might see this and consider your comment to have any relevance. You sound like the typical expert and I doubt you will ever take time to run some tests or consider anything other than what you think you already know to be true. Without running tests you only know what you’re told. And what you choose to believe is your choice. I’m sure you trust your other sources more than me but I’m only talking mower decks here. This could also be useful information but folks who are stuck on other applications won’t typically accept this advice and don’t think outside the application they are “experts at” experts like to think they know everything about bearings because what they know for one type must fit all applications. Seems logical I guess. so hopefully the effort I put into this comment can help someone else who really wants to find the truth and is willing to do some hands on tests. lots to unpack here, first I can say not all bearings come with the same quality or amount, Iv noticed some have almost none and others have a lot. And this is from the same box of bulk bearings of the same part number. So that’s BS statement for the bearings in this application. Quality of bearing and many other factors could be involved in how much and what quality grease will be in the bearing. Most likely the important aspect would be the bearing application and how high quality is needed. I do not advise to remove the shield but at the same time the inner shield being gone for this application won’t matter one bit. Some bearings don’t come with an inner facing shield, some do. I just wanted to prove the grease will pass the shield if it is there. And it clearly did not cause a problem in my video and also never has caused an issue and not one single time in my life has it ever been an issue, if you noticed in the video both shields stayed in place none had dislodged after grease was applied. And that’s exactly why I did a detailed step by step process to show how all the naysayers are wrong. No contamination is inside the assembly unless someone waits years to grease and some moisture gets in the assembly some rust can develop but I would say regardless it is better to have more grease in the bearings than it would be to let them run dry and guarantee failure. I invite all naysayers to please please post some videos and show us the link right here. We are eager to see some proof of what you speak. I’m not working on boats, aircraft, rockets, race cars, we are just talking mower deck bearings. So what you’re saying is one bearing should be addressed just like every bearing. One process for one bearing applies to the whole group? Are you saying Not any bearings in the world can be greased as I’m shown for any applications? So you say you may damage the seal? The way you say it sounds like you’re not very confident. Using the word MAY, And no you can’t put too much in these for this application more is better. The shields don’t hold pressure. Grease passes right out the outer shield. No, don’t forget about the zerk, use it. Dang that was a great example of the experts who try to give us advice. Sorry but your information is absolutely garbage. Rather than get mad about it, consider you’re not as knowledgeable as you think you are. Nobody knows everything. You have an opportunity to grow from this. Run some tests see what happens. I’ll even give you the most simple test you could ever do, grease one side as Iv shown and run the other side as is and see what side lasts longer. These bearings in box store and even some tractors considered commercial grade won’t last over 300 hours without grease added. Keep in mind that the average home owner has no interest in dismantling a deck and replacing parts that require tear down time and parts when it could simply be greased through a zerk that is put there by the manufacturer. This stuff ain’t rocket science and as I showed clearly in my video it works fantastically and plenty of folks doing it this way are sharing comments that it’s been working just fine for decades. Some folks are too smart and overthink this application and will never try it but it’s also helping many folks and that’s why I made it. Not all folks will be able to absorb this simple installation. Rather than run an experiment many folks will always assume they are smarter and know better even though they can’t reference anything backing their claims. In two years no naysayers have provided a video to show of any downsides. I’ll keep waiting. Why would anyone trust the company selling the equipment when they say something can’t be serviced? They ultimately make more money by selling parts and equipment. If I can keep my equipment running without buying replacement machines and or replacing parts I win and use my $ elsewhere. I’ll trust the facts that Iv done the trial and error to learn. No thanks on lifetime bearings and lifetime transmission fluid, this stuff has been debunked.

I need your advice on my JD Ztrak 375R. Today I sharpened the blades but reinstalled one blade upside down. The. Spindle did NOT like that at all because I smelled something burning and noticed it started smoking. I turned it off and noticed my error. However the spindle shroud where the blade bolt meets had gotten so hot it fell off and was hotter than hell. Once it cooled down I reinstalled the blade the right way and it cut just fine. I was not able to insert any grease in the zerk unfortunately. So maybe I damaged the zerk??? My question is did I do any damage to the spindle if it was smoking?????? And I did watch your video last year and followed your instructions to the letter with 75 pumps earlier his year. Just a boneheaded mistake which happens to guys on occasion.

Far too much grease in the bearing. SKF who I would consider the world expert recommends the amount of grease as determined by the SKF formula G = DB/10, where G is grease in ounces, and D is bearing outer. Dismantling and repacking would be my recommendation or just fitting new SKF, German, or Japanese bearings directly from a bearing house. Too many fakes on eBay. A proper bearing extractor and insert tool will mean the housing will not be damaged and perform as new along with heating the housing and cooling the bearing for an easy fit.

So do those SKF “””Experts”””” specifically discuss this application? Just love to see that data. Actually for this application it works fantastic. Sometimes it’s just not that complicated and why does it work out that my bearings last 20 plus years when I grease like Iv shown, the same way my grandpa did his old school “real” cub cadets. Before the box store junk mower builder better known as MTd (MADE TO DIE) took them over. but these days they fail in well under 100 hours on some box store tractors including the 100 Series Deere, when not greased. I’ll keep pumping mine full like Iv shown because it works better than not greasing. And the majority of folks are not going to pull bearings to add a metered amount of grease. Thats kinda comical really. Most folks won’t even grease them with a gun, they sure won’t take the deck apart to put a calculated exact fraction of grease into a bearing. Dont get me weong, If you have hard evidence this procedure causes failures, i invite you to please make videos with the evidence and helpful information that can do good for the DIY community. Otherwise your just another naysayer blindly following experts and with no evidence. This is not helping anybody. A bearing in this application will not overheat from over greasing, the seals don’t hold pressure. Any extra grease will push out of the way and out the lip of seal.

But if you're already taking your deck off for something else, say, to replace your blades, why not to it at that point? It's a small marginal increase in the size of the job.

Plenty of other channels explain how to dismantle the assembly to access a bearing and mislead the DIY community by informing folks that the shields stop the flow of grease. I have made this video to Debunk those fraudulent claims. Folks who make videos stating a shield stops grease flow should consider running some tests before posting misinformation. This subject is very controversial because so many channels won’t put any evidence in the videos and simply spend the time bumping gums when they should be showing the steps and proving why or why not. The truth can be found by each DIYer by simply following the process Iv shown. If folks don’t trust me they can test for themselves.

Only to help folks. As for why the manufacture of a box store mower won’t properly fill a bearing or add a quality grease, that’s a question you should try to extract from big corp. after 20 years of trials and error Iv found this to be a bullet proof way to make deck bearings go for ever if properly maintained they can outlast the engine and other components if maintenance is started from day one. As for naysayers who have no real hands on experience and want to argue, I’m your huckleberry. If you think the big corps care about us and if you think they don’t engineer failure into these machines your sadly mistaken. The quality in the last 20 years is baffling to myself and I’m sure others who work on mowers. I seen a video from one of the top channels just a few days ago where he is basically getting out of the business because of how bad it has gotten. To think these bearings should only have 25% grease is absolutely insane when they put a zerk on the assembly. Be realistic, nobody can pump 25% grease into a unit. And commercial and all the old school units were always pump till you see grease. How did that get lost in the last 20 years? Because manufacturers quit proposing the directions and left it to the owners to figure out. Who would think it would take 60 to 90 pumps to fill the void? Answer is very few folks would realize that and only folks with substantial knowledge or impressive intuition would know better. But thankfully I decided enough was enough and stepped in to help folks rather than be a brain dead mower channel and give folks the same stupid advice because I’m too lazy to run some hands on trials in my shop. I did this for me to keep my machines running: took me years to realize not a single person out there was peoviding the information I knew was true. Your welcome and hope your not offended but I call it like it is and if your build like the old timers you can take one on the chin and accept when your wrong.

But I will say with 100% certinty some of these new machines will loose bearings at under 100hours without adding grease. Go get a 100series Deere from Home Depot. You better add grease or it will cost you. Even the bad boy zero turns can’t last over 400 hours without bearing failures. Iv seen some bad boys loose bearings at 200.

Did you check the underside? I’m not familiar with XT1 but on the cubs prior to that model the zeros were hidden under the bottom and a slight grass accusation on the mandrels cover the zerk and hide it from view. I hate when they put them on the bottom. They get covered with grass

Take some time take the seal out ones a year why its down repack the bearing good for one more year and save all that grease
@GTObearclaw1Ай бұрын
No thanks. That’s amateur stuff. If the assembly has a zerk there is absolutely No need to take the deck apart just to remove the shields. They don’t stop grease from passing into the bearing as Iv shown. Doing all that work gets you no better lubrication and is simply just a 100% waste of time. The only way I’d recommend that is if the unit has no grease zerks or if the unit has a weephole. If that was the case I’d plug the weephole and add a zerk long before I’d consider taking my deck apart every years.

Got a Case J46 deck. Added fittings to the spindle body and pumped them full until grease leaked out of the ends. The shaft spun harder. Couldn't figure out why. I either hydraulicly pushed a bearing out of position or pushed a seal into the rollers . I just ordered replacement spindles with bearings with new bearings installed. I'll find out what I actually screwed up when the new spindles get here.
@GTObearclaw1Ай бұрын
Case is a commercial grade or heavy duty machine. My guess is it would be fine to run it but it’s hard to say without seeing how stiff they are. I notice they get a little stiffer in the cheep box store mowers but quickly free up after running a few minutes and letting the grease migrate.

Missing in action. I dont always get all the pieces that break off. And not everyone cares about a wheel being there. Some of these tractors are just beaters. Some folks just need to get the grass mowed. Just my 2 cents, Those wheels are not as useful as folks think. Cheep model tractors might have none, mid grade model has a few. Some deluxe models have 4 or 5 deck wheels. In my opinion the wheels are more of a gimmick but that’s just how I feel about them on the cheep mowers. I like them on the bigger tractors that allow them to be greased and have wider decks that can cut deep if deck leans to far one way.

Some folks don’t realize It’s just the lip of the seal that lets grease move past. Maybe some confusion due to the word seal being thought of as a hydraulic cylinder seal. Not sure but that’s how some of the comments seem to be making me feel. Also some concern about the the shield caps coming off the bearing. But they can’t unseat in this assembly unless something is assembled wrong. I challenge anybody to unseat one of these seal caps with a grease gun in a properly functioning unit. I’d like to see proof that it has happend. Iv never seen it happen. These units have no tolerance for movement. Not even a mm. The shields stay in place. Grease flows past seal. Very basic, but yet a lot of confusion on this topic.
@youtubular007Ай бұрын
I did this on my own mower decks a few years ago and can confirm same result with red grease that it definitely passes in to both upper and lower bearings with inner rubber seal. Yes, it takes a LOT of grease but a grease tube is cheaper than a spindle. I do wonder if the upper bearing heats up to the point it melts grease and leaks out back into the housing. I wonder if anyone has done a good test on that yet. I have not yet. Also serviceable spindle manufacturers could help us out a bit by putting some volume spacers inside the housing which would reduce the amount of grease necessary to fill it to the point of pressure to pass by the inner seals.
@GTObearclaw1Ай бұрын
Good thought on the void filler. I have also considered that idea. No I don’t think a good greased bearing produces enough heat to matter. My wheel bearings on a loaded trailer don’t even melt grease much
@TishaHayesАй бұрын
The seals are meant to keep dirt and grit out of the bearing race. A hand-pumped grease gun can deliver about 7000 PSI of pressure once the air voids are filled up in the annular space. The seals usually cannot hold back anything greater than about 500 PSI. You would want to try and NOT blow out the outer seal (steel or rubber/plastic) because it creates a future path for contamination back in to the bearing. The inner seal mostly serves the purposes of preventing race and ball damage from grit or dirt if the other bearing is compromised. (Engineer here, responsible for plant machinery maintenance crews at an oil and gas facility)
@GTObearclaw1Ай бұрын
As usual an expert with advice we can simply throw into the trash. Those seals won’t hold 500psi that’s an absurd number. You are way off track and probably comparing what you know about some other bearings. Have you ever had one of these type of mandrel bearings in you hand to visually inspect? Just because someone is an engineer does not know they know everything. Especially if they find it necessary to make it known. My experience with engineers leads me the opposite direction. I question everything they do. As a mechanic I see too much absolutely stupid stuff. Yet I don’t see engineers coming out to ask a mechanic if something makes sense. Why not ask the guys who actually fix this stuff? These seals would not be capable of holding 5psi let alone 500. That’s one of the most ridiculous things iv ever heard. This is how these are designed to be greased. If you have t done it and don’t have any experience your not one to give advice. If you have hands on experience with a failure occurring due to greasing the way Iv shown please do share. But not a master yet has any hands on proof. And they most certainly won’t take time to make a video to prove so. Your comment is bogus. The guns can actually reach upwards of 15000psi. That’s not gonna be what goes into these bearings. When you can prove that a seal can be damaged in this application please come back with that evidence. This application will be just fine doing as Iv shown. Caps are installed in a way they can’t push off the bearing. Only the seal of lip lets grease pass.

@GTObearclaw1Ай бұрын
I somewhat agree. Except I don’t think the grease spins out. I believe it’s just low quality and also a lesser quantity than should be used from the factory to make the bearings fail quicker. Some folks leaving comments saying they had tractors from 25 years ago last 20 ply years without a service. Hard to say but most likely the lower grade grease, less grease and lower quality parts used these days all coming together to lower the lifetime of these parts on the cheep machines. Probably one reason Briggs is now cutting he snapped and Ariens names, and the lack of sales have a lot to do with the low quality.

Im not saying some machines are not built better than others. Your tractor is not representative of all tractors. Not to mention things have changed in 25 years. You won’t find craftsman bearings in the new ones to last that long. 25 years ago you got a lot better quality machine than what they provide today. Quality has gone down hill. The way I show takes time but that’s just to make the point to clear up the confusion on this subject. However it is actually not a very time consuming project to connect a grease guns and service. It takes about 5 minutes to grease a few mandrels the way Iv shown. And that’s 5 minutes for the first time to fill the voids. Future greasing would be even faster only needing a few pumps on latter services after voids are full. I’m sure you realize it takes more than 5 minutes to change bearings, that’s just a silly thing to say that it would be faster to change bearings. Be realistic, no need to be dramatic. The information is helpful to some. Some folks can find error in anything.

As a millwright, experienced in dealing with bearings for many, many years, I can tell you that removing the seals on a factory sealed bearing is entirely wrong. They are lubricated with the exact amount of grease, and as long as the seals are in good shape it’s far better to leave them alone. Once you remove a seal, grease can enter, but so can contaminants. Too much grease will cause overheating and shorten the life of the bearing. For a mower deck, check the spindles annually and replace any worn bearings with sealed bearings. Forget about the Zirk fitting, pumping grease in there won’t do anything to prevent damage. If you remove the inside seals on these bearings and pump the housing full of grease, you may put too much in and dislodge the outer seals, and then you’ll destroy both bearings.
This comment is not to help you but for the third party that might see this and consider your comment to have any relevance. You sound like the typical expert and I doubt you will ever take time to run some tests or consider anything other than what you think you already know to be true. Without running tests you only know what you’re told. And what you choose to believe is your choice. I’m sure you trust your other sources more than me but I’m only talking mower decks here. This could also be useful information but folks who are stuck on other applications won’t typically accept this advice and don’t think outside the application they are “experts at” experts like to think they know everything about bearings because what they know for one type must fit all applications. Seems logical I guess. so hopefully the effort I put into this comment can help someone else who really wants to find the truth and is willing to do some hands on tests. lots to unpack here, first I can say not all bearings come with the same quality or amount, Iv noticed some have almost none and others have a lot. And this is from the same box of bulk bearings of the same part number. So that’s BS statement for the bearings in this application. Quality of bearing and many other factors could be involved in how much and what quality grease will be in the bearing. Most likely the important aspect would be the bearing application and how high quality is needed. I do not advise to remove the shield but at the same time the inner shield being gone for this application won’t matter one bit. Some bearings don’t come with an inner facing shield, some do. I just wanted to prove the grease will pass the shield if it is there. And it clearly did not cause a problem in my video and also never has caused an issue and not one single time in my life has it ever been an issue, if you noticed in the video both shields stayed in place none had dislodged after grease was applied. And that’s exactly why I did a detailed step by step process to show how all the naysayers are wrong. No contamination is inside the assembly unless someone waits years to grease and some moisture gets in the assembly some rust can develop but I would say regardless it is better to have more grease in the bearings than it would be to let them run dry and guarantee failure. I invite all naysayers to please please post some videos and show us the link right here. We are eager to see some proof of what you speak. I’m not working on boats, aircraft, rockets, race cars, we are just talking mower deck bearings. So what you’re saying is one bearing should be addressed just like every bearing. One process for one bearing applies to the whole group? Are you saying Not any bearings in the world can be greased as I’m shown for any applications? So you say you may damage the seal? The way you say it sounds like you’re not very confident. Using the word MAY, And no you can’t put too much in these for this application more is better. The shields don’t hold pressure. Grease passes right out the outer shield. No, don’t forget about the zerk, use it. Dang that was a great example of the experts who try to give us advice. Sorry but your information is absolutely garbage. Rather than get mad about it, consider you’re not as knowledgeable as you think you are. Nobody knows everything. You have an opportunity to grow from this. Run some tests see what happens. I’ll even give you the most simple test you could ever do, grease one side as Iv shown and run the other side as is and see what side lasts longer. These bearings in box store and even some tractors considered commercial grade won’t last over 300 hours without grease added. Keep in mind that the average home owner has no interest in dismantling a deck and replacing parts that require tear down time and parts when it could simply be greased through a zerk that is put there by the manufacturer. This stuff ain’t rocket science and as I showed clearly in my video it works fantastically and plenty of folks doing it this way are sharing comments that it’s been working just fine for decades. Some folks are too smart and overthink this application and will never try it but it’s also helping many folks and that’s why I made it. Not all folks will be able to absorb this simple installation. Rather than run an experiment many folks will always assume they are smarter and know better even though they can’t reference anything backing their claims. In two years no naysayers have provided a video to show of any downsides. I’ll keep waiting. Why would anyone trust the company selling the equipment when they say something can’t be serviced? They ultimately make more money by selling parts and equipment. If I can keep my equipment running without buying replacement machines and or replacing parts I win and use my $ elsewhere. I’ll trust the facts that Iv done the trial and error to learn. No thanks on lifetime bearings and lifetime transmission fluid, this stuff has been debunked.

I need your advice on my JD Ztrak 375R. Today I sharpened the blades but reinstalled one blade upside down. The. Spindle did NOT like that at all because I smelled something burning and noticed it started smoking. I turned it off and noticed my error. However the spindle shroud where the blade bolt meets had gotten so hot it fell off and was hotter than hell. Once it cooled down I reinstalled the blade the right way and it cut just fine. I was not able to insert any grease in the zerk unfortunately. So maybe I damaged the zerk??? My question is did I do any damage to the spindle if it was smoking?????? And I did watch your video last year and followed your instructions to the letter with 75 pumps earlier his year. Just a boneheaded mistake which happens to guys on occasion. Surprised it reacted the way it did with getting hot and smoking.
Probably just friction from the blade spinning loose and getting hot from metal To metal Friction. It may have got the bearings hot. I’m sure the rubber shield lips didn’t like it. But I’d keep it greased and run it. Sorry to hear about that and yes we all have mistakes.

Simply not what this video was made to prove. My point is that there is no need to go this deep into a bearing. Latter in the video I show how using the grease gun achieved that same result without any need for dismantling a deck. It all makes sense in the end. Needed to prove a point.

Far too much grease in the bearing. SKF who I would consider the world expert recommends the amount of grease as determined by the SKF formula G = DB/10, where G is grease in ounces, and D is bearing outer. Dismantling and repacking would be my recommendation or just fitting new SKF, German, or Japanese bearings directly from a bearing house. Too many fakes on eBay. A proper bearing extractor and insert tool will mean the housing will not be damaged and perform as new along with heating the housing and cooling the bearing for an easy fit.
So do those SKF “””Experts”””” specifically discuss this application? Just love to see that data. Actually for this application it works fantastic. Sometimes it’s just not that complicated and why does it work out that my bearings last 20 plus years when I grease like Iv shown, the same way my grandpa did his old school “real” cub cadets. Before the box store junk mower builder better known as MTd (MADE TO DIE) took them over. but these days they fail in well under 100 hours on some box store tractors including the 100 Series Deere, when not greased. I’ll keep pumping mine full like Iv shown because it works better than not greasing. And the majority of folks are not going to pull bearings to add a metered amount of grease. Thats kinda comical really. Most folks won’t even grease them with a gun, they sure won’t take the deck apart to put a calculated exact fraction of grease into a bearing. Dont get me weong, If you have hard evidence this procedure causes failures, i invite you to please make videos with the evidence and helpful information that can do good for the DIY community. Otherwise your just another naysayer blindly following experts and with no evidence. This is not helping anybody. A bearing in this application will not overheat from over greasing, the seals don’t hold pressure. Any extra grease will push out of the way and out the lip of seal. If you can prove otherwise I’m ready to watch your video. Please post right here for us all If you have links to your own videos or others on the topic or any data for that matter other than general advice for bearings that do not cover the use of bearings in this application. This video is strictly for deck bearings and what id like to keep it focused on. Too many other applications that run diffrent loads and different RPms that won’t meet the use of the bearings in the mower deck mandrel application.
Russ, I’ve used this repair method once so far and it was quick and easy! Thanks so much for posting this - I haven’t seen it anywhere else in over 5K hours of KZread University over almost 3 years. I’ve sent this link to numerous small engine people and just posted it in a comment on donyboy73’s channel.
So, not an expert, but the reason I didn't grease them because in my Manual for my deck it states: "IMPORTANT: DO NOT add grease to spindle grease fitting. They are for manufacturers use only. Adding grease may damage spindle seals." Is this the same fitting, and if so could any1 elaborate why it would still be okay?
Don’t grease them the bearings will fail. Add grease they go long time. Do as you wish. Apparently nobody is an expert. However Iv shown it works just fine been doing it almost 20 years no issues.
@@GTObearclaw1 Right on, no argument here, just trying to understand why its suggested not to, thanks for video.
@@ApothecaryRdy my guess is so it fails sooner and you go to them for parts or services or a new tractor
@@GTObearclaw1 🤣
One thing that bothers me about so many of these bearing videos. I agree that is absolutely essential to have grease in bearings and sealed can be a bad idea. But why is it NO ONE ever sticks a thumb in the bearing inner race to rotate it and see if the bearing is still smooth & good. See if it is good folks before you take the trouble to grease it! Geez. Same issue with motorcycle wheel bearings. But overall, a great presentation. Thank you young man!
I recon I didn’t care about if the bearings were smooth or not just to prove my point. But I think anyone would have the natural instinct to check the feel of the rotating bearing to guage if it has obvious gritty feel. I know I always check them and spin the assembly before teardown to see if I feel an issue. If I feel an issue I explore deeper to see what one is bad, usually the bottom.
@@GTObearclaw1 You're the kind of mechanic I would have liked to work with when I was younger and still working!
Why not just pop the inner seals out?
I thought I clearly explained in the video why removing seals is not necessary. If unit has grease zerks I have proven that making the effort to do such is a pure waste of time. Some folks appreciate the detail I went into to prove my point on the process. Just trying to save folks some time. Unless your unit has a weep hole in the side of the assembly between the bearings this process works 100% of the time. Poping the seals out won’t add any benefit just more work For the same results.
@@GTObearclaw1 I do believe that you've proven that grease makes it inside the bearing under pressure. You've also proven that the people telling us to not bother greasing the spindle fittings are wrong. I don't believe that you've proven that there's no use or benefit to removing the bearing seal facing the grease chamber. I don't doubt you per se. I just think it bears further research. If you don't have to take your deck off right now, by all means, simply pump grease into that fitting. But if you're already taking your deck off for something else, say, to replace your blades, why not to it at that point? It's a small marginal increase in the size of the job. It would still take some convincing for me to believe the manufacturer's contention that having that seal in place was a good idea in the first place.
@@pleappleappleap I have no issue with someone running some tests. I’d love to see the results. However if the grease gets into the bearings I don’t see what difference the shield makes one way or another therefore what good would it do to remove it until it’s proven that would make a difference. I tend to believe it’s just as beneficial if left in place as it is if it’s removed. An argument could be made either way. I don’t have those facts. I was mostly concerned about folks believing the advice others provide saying it’s a waste of time. Hopefully it helps some folks. According to the overwhelming comments I believe it’s more of a hot topic than I ever imagined. It was a topic that never set right with me when I started seeing those videos saying don’t grease them. Thanks for the additional comment now I see more what you meant by the first comment.
@@GTObearclaw1 It is just a difference of degree. I think more grease will get in. But your original point that the fitting needs regular grease is more important, and I agree wholeheartedly.
Why wouldn't you just pack the bearings with grease, when the seals are off?
I understand that is one way, that is the more complex way to reach the same goal as I achieved in my video. The purpose of this video was to show it’s not necessary to dismantle a mandrel to access a bearing and manually pack grease in the bearings. As I deminstrate in the video, grease applied through a zerk provides the bearings with grease with no issues. Plenty of other channels explain how to dismantle the assembly to access a bearing and mislead the DIY community by informing folks that the shields stop the flow of grease. I have made this video to Debunk those fraudulent claims. Folks who make videos stating a shield stops grease flow should consider running some tests before posting misinformation. This subject is very controversial because so many channels won’t put any evidence in the videos and simply spend the time bumping gums when they should be showing the steps and proving why or why not. The truth can be found by each DIYer by simply following the process Iv shown. If folks don’t trust me they can test for themselves. I’m just trying to help reveal the truth about the factory installed zerks and how little effort it takes to get grease past an inner shield. Simple stuff when we really think about the process.
Good straight forward information. an old saying fits the stupid idea of not greasing spindles or only putting a few pumps in it. 'It failed because it was burnt up with grease' 😅😅😅 Comment sense says if there is a grease zerk there, it should be greased. I have a simplicity 54" deck with 3 spindles that take 50 pumps to fill completely up.
Why didn’t you go ahead and pack it with grease with shield off?
Did you watch the whole video? I feel maybe you missed some parts if your asking that question. I could be wrong. However, I had some points to make. I was not showing how to do it that way. I was showing that the seals take grease and how many pumps it takes. It was necessary to do it the way I showed so folks would know when filling a new unit how it will be done. Taking these apart to fill the inside with grease manually is not normal and would be confusing if it was mixed with the information I was presenting in this video. It’s simply easier and less mess to connect a grease gun and pump the assembly full.
Thanks for the grease gun pump count. I added fittings to a couple towers and packed them full as i could,then pumped them up until i saw grease coming out. Next time id rather just pump them up. Great video!
You have got the hard part out of the way. Now that they are full it will only require a few pumps on the future survices.
70 pumps of grease. That can get expensive.
Okay. So if a tube has several hundred pumps in it. How much $ are you complaining about exactly? 5$ expensive to you? Vs a bearing value taking out a mandrel ? Geez what are we even talking about? Next thing you’re gonna tell me an oil change is too expensive so we just run the engine to failure because that seems more reasonable? What could you be trying to say here? Please elaborate so I don’t have image what your trying to say. Keep in mind. After the assembly is filled it only takes a few pumps for all the future greasing. So like 50 cents or less.
why not just leave the rubber seals out completely? That way the grease would always get there
Ask the manufacturer If you want to Dismantle to remove a seal that can’t stop grease then get to it. But why? It is irrelevant and the whole point of the video.
Over-greasing tutorial. If you do this, your bearings have too much grease in them.
Apparently you don’t know jack crap about mower decks. But eager to run your mouth I see. This is basic mower servicing 101. Can’t over grease these. Assembly won’t hold pressure. looks like we have another expert ready to provide us the information we need with no proof in sight. Just an expert with no evidence of any facts. Can’t wait to hear your credentials. Another engineer or do you work on aircraft? I’m so eager to hear what makes you an expert. I’ll bet you don’t post a video to prove your point. Are you just one more expert who knows it all but too lazy to make a video and show us the dangers of “over greasing”? 😂 I won’t hold my breath. In two years not a single naysayer has provided a shred of Evidence that over greasing is possible in this application. News flash, it’s not a thing for mower deck manufacturers chif.
@GTObearclaw1 So explain super brain why these sealed bearings come with about 25% fill of grease by volume. Seeing as you are more knowledgeable than the manufacturers or engineers or professional maintenance personnel.
@@dennismoore1116 if knowing one thing in life makes me a super brain, then that’s awesome and first time Iv heard that. But I’ll take any compliment you want to offer. I may not be any more knowledgeable than the manufacturer however I’m willing to offer the information and they don’t. Just take some time to let that soak in a while. What do I stand to gain? Nothing. What do they stand to gain by not offering information to make decks run longer? O simple, parts sold or more machines sold. however my gole is to get folks bearings to last forever without need to spend money. I don’t get paid one way or another. Just like to see people have the real story. And that’s why I did the baby step video. I have no benefit from this other than to see folks receive the information needed to make the decks go for as long as possible. I didnt make this video with the idea of making a proft. Only to help folks. As for why the manufacture of a box store mower won’t properly fill a bearing or add a quality grease, that’s a question you should try to extract from big corp. after 20 years of trials and error Iv found this to be a bullet proof way to make deck bearings go for ever if properly maintained they can outlast the engine and other components if maintenance is started from day one. As for naysayers who have no real hands on experience and want to argue, I’m your huckleberry. If you think the big corps care about us and if you think they don’t engineer failure into these machines your sadly mistaken. The quality in the last 20 years is baffling to myself and I’m sure others who work on mowers. I seen a video from one of the top channels just a few days ago where he is basically getting out of the business because of how bad it has gotten. To think these bearings should only have 25% grease is absolutely insane when they put a zerk on the assembly. Be realistic, nobody can pump 25% grease into a unit. And commercial and all the old school units were always pump till you see grease. How did that get lost in the last 20 years? Because manufacturers quit proposing the directions and left it to the owners to figure out. Who would think it would take 60 to 90 pumps to fill the void? Answer is very few folks would realize that and only folks with substantial knowledge or impressive intuition would know better. But thankfully I decided enough was enough and stepped in to help folks rather than be a brain dead mower channel and give folks the same stupid advice because I’m too lazy to run some hands on trials in my shop. I did this for me to keep my machines running: took me years to realize not a single person out there was peoviding the information I knew was true. Your welcome and hope your not offended but I call it like it is and if your build like the old timers you can take one on the chin and accept when your wrong. Otherwise I’m sure you can go full Karen and throw some insults. But I’m here with evidence that can be tested by anybody and left nothing to be questioned except does it work and there is one way to find out. My way may help your bearings go for ever. The other way leads to guaranteed eventual failure. So what are we arguing about here? For real? What?
@GTObearclaw1 You don't have maintenance experience as a professional do you? I've seen several of these decks out last the engine with no greasing. Sorry to burst your bubble, but they fill the bearings 25% because that is the proper amount and they don't expect regreasing.
@@dennismoore1116 your kidding right? im not claiming to be a professional and if you think folks can’t teach themselves in today’s technology your close minded. I guess you assume that only way to be a pro is to work for a company or something? I do not follow what I’m told, I do what makes sense when someone tells me something that seems stupid I test my theory and see what really happens. Iv seen professionals tell a man he needed a new 600$ transmission in a 20 year old tractor. He refused to pay the repair and left the tractor at the shop. That shop told me I could have the tractor if I paid the diag time. I got it for 100$ welded the pully to the shaft and mowed with it 5 more years. So what kind of professional was that? They didn’t help the customer. Dont be dooped. I’m not saying some machines don’t come with a higher quality bearing and an excellent quality grease that can last a long time. But I will say with 100% certinty some of these new machines will loose bearings at under 100hours without adding grease. Go get a 100series Deere from Home Depot. You better add grease or it will cost you. Even the bad boy zero turns can’t last over 400 hours without bearing failures. Iv seen some bad boys loose bearings at 200. And those are supposed to be commercial with no grease zerk? Absolutely ridiculous. Just the facts these days. You’re on the wrong side of this and you don’t know it. You’re basing you may be basing your argument on a handful of lucky experiences. But that’s not the reality in the mower world. If it has a zerk, be thankful and grease it. Some machines like bad boy don’t all come with zerks and Iv replaced enough bad bearings and checked the hour meters less than 4 years old and bearings gone. It’s simple preventative maintenance. Do you trust engineers and doctors just because of their titles?
I’m going to grease my spindles!
Great news, save money make those babies run forever. Dont blow money for repairs that could have been easily avaided
I Need To Find Out How Often (Number Of Hours) I Need To Grease The Mower Deck Spindle Bearings On My John Deere Z930M. Very Helpful Video.
My Cub Cadet ZT1 spindles don't have grease zerks. I guess if I want to grease them, I have to take them apart?
Did you check the underside? I’m not familiar with XT1 but on the cubs prior to that model the zeros were hidden under the bottom and a slight grass accusation on the mandrels cover the zerk and hide it from view. I hate when they put them on the bottom. They get covered with grass
@GTObearclaw1 Yes, I looked under the bottom. No zerks. Also saw on another website that they don't have them. The only 2 zerks on the machine is in the front 2 wheels. Terrible engineering.
@@AaronRankin sounds like cub is in a nose dive. mTD really running the cub name straight into the ground. Iv hated cub ever since MTD got ahold of the brand.
@GTObearclaw1 I agree my 1973 Cub Cadet 129 still runs and is built like a tank. They'll never be the same again.
@@AaronRankin cub is not cub anymore. Just a sticker on a MTD tractor with yellow and white paint. Fake
Take some time take the seal out ones a year why its down repack the bearing good for one more year and save all that grease
No thanks. That’s amateur stuff. If the assembly has a zerk there is absolutely No need to take the deck apart just to remove the shields. They don’t stop grease from passing into the bearing as Iv shown. Doing all that work gets you no better lubrication and is simply just a 100% waste of time. The only way I’d recommend that is if the unit has no grease zerks or if the unit has a weephole. If that was the case I’d plug the weephole and add a zerk long before I’d consider taking my deck apart every years.
Whatever you go ahead and believe that s***
Thanks! I watched some bad information about removing the seal so the grease could get in. I’m replacing spindles this weekend on La 145. I’m glad I watched your video which proves the grease finds its way in. When the deck is cutting and grease warms up it probably coats bearings even better 👍🏻
Thanks for the comment! Yes lots of bad information out there. Sadly i commented on some of the pros videos and tried to get them to run some tests but nobody would. I finally decided to just do it myself but figured it would get more attention on a Chanel with a bigger following. However it gained a lot more attention than I expected so I’m glad I did it myself.
Motor repairman for over 40 years. Biggest cause of bearing failure is dirt. That is why they use sealed bearings.
No argument from me, I know they will fail without grease, Just hoping to shed some light on how to get grease to the bearings as easily as possible.
So what you're saying is leave the seals there on both sides of each bearing, just grease the shit out of it till you see grease coming out somewhere?
Precisely
Wow! Lesson learned - - so glad you posted this video - - thank you!
Had no idea what you took apart to accomplish this, but I’m sure this was good advice for those who know how to take their mower apart to grease the bearings.
The point is that the units don’t need to come apart to simply grease the bearings. Most folks think the grease zerks are not funny I was only proving they are functional. It was only disassembled to show grease reached the bearings.
It isn't quite clear. Were the old bearings reused, and the old rubber seals put back in? ( I didn't know you could put seals back in.) Or were new sealed bearings installed? (Yes, I understand that with enough pressure the grease can pass past the lip of the seal.)
I was simply using the used parts to show that grease passed. Yes for these type bearings caps pop off and on easily if in good condition
Got a Case J46 deck. Added fittings to the spindle body and pumped them full until grease leaked out of the ends. The shaft spun harder. Couldn't figure out why. I either hydraulicly pushed a bearing out of position or pushed a seal into the rollers . I just ordered replacement spindles with bearings with new bearings installed. I'll find out what I actually screwed up when the new spindles get here.
Case is a commercial grade or heavy duty machine. My guess is it would be fine to run it but it’s hard to say without seeing how stiff they are. I notice they get a little stiffer in the cheep box store mowers but quickly free up after running a few minutes and letting the grease migrate.
Where was the wheel/bracket that supposed to be near the patch and rod you welded?
Missing in action. I dont always get all the pieces that break off. And not everyone cares about a wheel being there. Some of these tractors are just beaters. Some folks just need to get the grass mowed. Just my 2 cents, Those wheels are not as useful as folks think. Cheep model tractors might have none, mid grade model has a few. Some deluxe models have 4 or 5 deck wheels. In my opinion the wheels are more of a gimmick but that’s just how I feel about them on the cheep mowers. I like them on the bigger tractors that allow them to be greased and have wider decks that can cut deep if deck leans to far one way.
What the hell? I SEE GREASE ZERKs on the side of your spindle housing! Are you insane?
Just as I thought. I'd like to see the bearing seal that could resist high pressure grease from squeezing through.
Some folks don’t realize It’s just the lip of the seal that lets grease move past. Maybe some confusion due to the word seal being thought of as a hydraulic cylinder seal. Not sure but that’s how some of the comments seem to be making me feel. Also some concern about the the shield caps coming off the bearing. But they can’t unseat in this assembly unless something is assembled wrong. I challenge anybody to unseat one of these seal caps with a grease gun in a properly functioning unit. I’d like to see proof that it has happend. Iv never seen it happen. These units have no tolerance for movement. Not even a mm. The shields stay in place. Grease flows past seal. Very basic, but yet a lot of confusion on this topic.
I did this on my own mower decks a few years ago and can confirm same result with red grease that it definitely passes in to both upper and lower bearings with inner rubber seal. Yes, it takes a LOT of grease but a grease tube is cheaper than a spindle. I do wonder if the upper bearing heats up to the point it melts grease and leaks out back into the housing. I wonder if anyone has done a good test on that yet. I have not yet. Also serviceable spindle manufacturers could help us out a bit by putting some volume spacers inside the housing which would reduce the amount of grease necessary to fill it to the point of pressure to pass by the inner seals.
Good thought on the void filler. I have also considered that idea. No I don’t think a good greased bearing produces enough heat to matter. My wheel bearings on a loaded trailer don’t even melt grease much
The seals are meant to keep dirt and grit out of the bearing race. A hand-pumped grease gun can deliver about 7000 PSI of pressure once the air voids are filled up in the annular space. The seals usually cannot hold back anything greater than about 500 PSI. You would want to try and NOT blow out the outer seal (steel or rubber/plastic) because it creates a future path for contamination back in to the bearing. The inner seal mostly serves the purposes of preventing race and ball damage from grit or dirt if the other bearing is compromised. (Engineer here, responsible for plant machinery maintenance crews at an oil and gas facility)
As usual an expert with advice we can simply throw into the trash. Those seals won’t hold 500psi that’s an absurd number. You are way off track and probably comparing what you know about some other bearings. Have you ever had one of these type of mandrel bearings in you hand to visually inspect? Just because someone is an engineer does not know they know everything. Especially if they find it necessary to make it known. My experience with engineers leads me the opposite direction. I question everything they do. As a mechanic I see too much absolutely stupid stuff. Yet I don’t see engineers coming out to ask a mechanic if something makes sense. Why not ask the guys who actually fix this stuff? These seals would not be capable of holding 5psi let alone 500. That’s one of the most ridiculous things iv ever heard. This is how these are designed to be greased. If you have t done it and don’t have any experience your not one to give advice. If you have hands on experience with a failure occurring due to greasing the way Iv shown please do share. But not a master yet has any hands on proof. And they most certainly won’t take time to make a video to prove so. Your comment is bogus. The guns can actually reach upwards of 15000psi. That’s not gonna be what goes into these bearings. When you can prove that a seal can be damaged in this application please come back with that evidence. This application will be just fine doing as Iv shown. Caps are installed in a way they can’t push off the bearing. Only the seal of lip lets grease pass.
And balance your blades! Cheap blades are totally out of whack. It will kill a spindle faster than not greasing.
Yea...donnyboy is an idiot. I see so many things he gets wrong.
This is the biggest problems with the new so called sealed spindles with sealed bearings. The very little grease that is in them new will spin out in no time and now you are wondering why your deck is so loud form spindle noise. They build them like this so you will have to buy new ones sooner.
I somewhat agree. Except I don’t think the grease spins out. I believe it’s just low quality and also a lesser quantity than should be used from the factory to make the bearings fail quicker. Some folks leaving comments saying they had tractors from 25 years ago last 20 ply years without a service. Hard to say but most likely the lower grade grease, less grease and lower quality parts used these days all coming together to lower the lifetime of these parts on the cheep machines. Probably one reason Briggs is now cutting he snapped and Ariens names, and the lack of sales have a lot to do with the low quality.
this was one of the best videos I have seen on you Tube. I am currently doing the same job on my J.D. 125 auto and you were right on about the grease not getting to the critical parts. thank you for the time and effort you put into this video. bill b
Thanks for commenting to let me know your thoughts. It’s always pleasant to see someone who agrees and appreciates the information. It’s ashamed the big corps won’t post videos to help folks. They put the zerks on but in hops that people are too lazy I guess. No extra help that I can find. The biggest issue is the huge void. No way the average person would know To fill that void with grease before it’s going to reach the bearings. That’s the basic stuff the manufacturer should be sharing.
The amount of time needed to grease sealed bearing you may as well replace them .used a craftsman for25 years and never greased them and sealed bearings were like new .
Im not saying some machines are not built better than others. Your tractor is not representative of all tractors. Not to mention things have changed in 25 years. You won’t find craftsman bearings in the new ones to last that long. 25 years ago you got a lot better quality machine than what they provide today. Quality has gone down hill. The way I show takes time but that’s just to make the point to clear up the confusion on this subject. However it is actually not a very time consuming project to connect a grease guns and service. It takes about 5 minutes to grease a few mandrels the way Iv shown. And that’s 5 minutes for the first time to fill the voids. Future greasing would be even faster only needing a few pumps on latter services after voids are full. I’m sure you realize it takes more than 5 minutes to change bearings, that’s just a silly thing to say that it would be faster to change bearings. Be realistic, no need to be dramatic. The information is helpful to some. Some folks can find error in anything.
This was meant for me to see, funny I just greased my spindles today (Installed new blades) I kept pumping like 30 times,nothing, after about 30 more it came out.😮
Nice, thanks for the comment and confirmation on how many pumps an empty mandrel can take. You’re set now, in the future 4 or 5 pumps will get you done. I had a deck this week on an older model Husqvarna zero turn and the mantels took 92 and the other took 94 pumps before I seen any grease come out.
@@GTObearclaw1 wow 92+ pumps mine is a 2003 Troy Built probably never greased, lol.
@@davidlaws1438 that’s impressive but I don’t doubt it. Your lucky it had zerks. they can go a long time without grease sometimes. Iv had some comments about folks not greasing for 20 years and Iv personally seen some fail after just a few years and less than 100 hours. I’m sure it all matters how much grease they came with and more than likely highly dependent on the quality of grease used for one to be able to last 20 plus years. I’d say your safe to go for many years now without grease but it’s easy enough to hit it with a few more pumps each year just in case one didn’t receive as much grease the prior time! It’s always better to be proactive!
@@GTObearclaw1 yes now that I know their there I will definitely grease every year. 👍
Sealed ball bearings are sealed and if anything can get through to them then they are defective and it is a waste of time to grease them cause the grease goes no where.
Are you a troll? Or just need more help? Did you even watch the full video to obtain the information or just knew you were an expert on the topic and too smart to need to see what I was doing here in the video? If this is a real comment, you’re over achieving at a level of ignorance that few of us can comprehend. I know I’m struggling to grasp the level of stupidity on you’re comment. I’m sure it’s simply rooted in a total lack of experience in the exact application I’m showing and possibly you have high level of experience with bearings of another application but you are off base here. Iv seen a lot of dumb comments but you’re competing for first place and that is not exactly an easy achievement for this video. Iv got some real zingers. It’s one thing to not know something because it’s new to you but this is a comment on a video with details on each step of the process. Nothing was hidden, no tricks. I know people struggle with this exact situation and what sealed bearing actually means for this exact application. And that’s exactly why I explained it to the painful detail. If you still can’t grasp this point after it was broke down into the slow motion detail you probably shouldn’t own any tools. Nobody is stoping you from running personal experiments to find out how well this actually works. This is a basic as changing an air filter and doing routine oil changes. Not exactly rocket science at any level. Just basic day one mechanic stuff. And the kind of stuff everyone should know who wants to keep a mower deck operational for as long as possible without failure. Thanks for taking time to leave a comment.
Thank you for doing this video. I have always been unsure that I am getting the grease to go where I want it to bee. You have set my mind at ease regarding seal bearings. I will pump till I see it. Cheers.
To much grease is harmful also, worked maintenance for 45 years in an aircraft manufacturing plant. Don’t listen to fly by nights.
Hay boss, did you notice this was not an airplane part. Did you see any airplanes in my shop? Did I say I was greasing aircraft bearings? Or did that little detail fly over your head? You’re just another expert I see. Of course every bearing in the world must be just like aircraft bearings since that’s what your an expert about so now your the one we should know a trust. Even though you don’t have any videos to help us with mower deck bearings. Another expert, Same as the ones I advise to watch out for. Dont trust an expert. Trust what can be proven and seen and tried at home. Even trial and error is more responsible than just taking some clowns word for it. Whoever gives the advice, find the truth don’t just trust what we are told. Iv proven this works for 20 years never had an issue not a single time. It’s how they are made to be used. I have provided proof the process works, yup the video where I proved facts on non airplane parts. I guess because you think airplane bearings are the same as everything else, now you’re the lead consultant for all bearing related matters and they all fit the same category and fall under your umbrella of expert status. What a total load of bull crap, I believe a true air craft mechanic would have basic common scene and know better, so I doubt your credibility. But nice try, few if any will listen to your advice. Terrable as it is, not the worst Iv seen or heard. Hay but it’s free to post videos and boast your expert status. Dont let me stop ya. Fly your arse over to the camera and get us some more gold nuggets on video. Can wait to see what kind of Jewels you drop on us.
