Sorry guys, a lot of stuff (most of it garbage) ends up being cut in a video this long, but I left out two things: I have been tracking costs for this project, and will be sharing the info. Also the hillbilly intake heater is still a work in progress, and the next version is waaaaaaay better. It just is gonna require some custom duct ta...errr machining work. Thanks for watching, I appreciate your guy's feedback.

Great job, not real keen on the manifold heater that way, u should put back in square part and modify inlet to suit because it will short out inside manifold

Some of the best editing on KZread. By getting to the things of importance without watching you consume vast amounts of time doing what we know has to be done, you've kept it interesting and informative. Great job on your machine and the presentation.

So true. I got so used to watching video in a half arse manner while we're subjected to the noise of tools and process I don't want to see that I had to play this three times over to catch it all. Every viewing was a pleasure still.

Matt, I've been working on CATS since 97. My boss never gave me the time to do the repairs that needed to be done. He always said sitting iron doesn't make money. He never understood that half ass repairs are always in the shop. Love this series 👍

Mabey your wrong about your boss, might not have given you enough time for complete fix, so he would see cat back in shop for more billable half-ass repairs. Just a thought

Have been watching this series from the Recovery video. Great work. Thanks for making everything so clear and not being afraid to show the process. Any mechanic knows, on unknown machinery it's always a learning curve. Can't wait to see the finished product working. Then on to the Hitachi. Should be fun.

Ditto to that! 👍

Given your approach and handling of the issues you are finding as you're restoring your Cat. Plus the factyou are putting in the effort to go online to find info, manuals, parts and advice pretty much puts you work at the professional level. You'd definitely make one heck of a darn good aircraft mechanic. I'll almost be sad when this series is finished it's so fascinating and entertaining.

Love your work. Don't fall into the trap of apologizing for how long your videos take to make, they are what they are and if you put that pressure on yourself you'll start to resent it. Appreciate the hard work.

I know I will never have to rebuild a hydraulic pump on a Cat D4U but I could not stop watching this and can’t wait for the next vid, cheers Matt thank you 👍

First thing is let me say thank you for taking the time to record this series to share with us, I am enjoying this immensely, I used to do this kind of work for a living and enjoyed it, I can no longer do it, but still enjoy the process. The second thing is that that pump and tank was by far and away the filthiest I have ever witnessed. You are doing an excellent job on the D4, thanks for the update sir.

Strongly suggest you put the outer brackets back on the hydraulic pump. There is a lot of torque generated when you engage the cylinders and you don’t want the flange mounts breaking.

A suggestion. The hydraulic lines that cross in front of the firewall were routed that way because of the pony motor. Since you don't have a pony motor, they could be rerouted across the top of the bell housing with the battery box mounted above them. There is not a lot of work involved, they could be either hose or pipe. This would clear up the control station and the firewall and make for a far cleaner look.

I could literally watch your videos over and over again! Not ONE boring sequense. Thank you so much for making KZread interesting! 👍

Very well said!

That wasn't a "chip" on that bearing race. that was a ball insert point. You're doing a great job Matt.

It's just incredible your ability to take complicated things apart, fix them and put them back together.

Found this series a couple months ago and binge watched the entire thing over several days. Thanks for bringing us along for this project. I love the old Cat stuff. Glad to see you have more projects lined up in the future. Your content is some of the best out there !

YES! ALWAYS glad to see one of your no-nonsense yet relaxed and FUN videos! Gives me hope that one day my backhoe will say nice things about me if I fix it up the same way.

I watched this over a couple of days. You have made this where a guy could get good information and instruction if he wanted to rebuild one of these cats. And, you showed the correct way to pour oil out of a 5 gallon bucket. 😁

By watching your series, I can sure see the importance of the videos. If you didn't make them, putting the machinery back together again could be a big guessing game. You've done great!

Another great video Matt. No need to apologise for the length of the video, it was absorbing from start to finish. Can't wait for the D4 to up and running so we can see the excavator being restored. But first things first eh!

Your attention to detail is impecable! is great how you are able to find specs and information in this old machine. You must be an engineer by trade. I have followed this entire project and it has been great to see the progress you have made. I will miss it when is all done

Man, you make old stuff look GOOD! You could easily work in a museum if you wanted. That bearing with the chip missing - I'm pretty sure that's what's known as a "Max Fill" bearing. It has a few extra balls in there to handle heavier loads, and it can't be assembled like a more standard bearing. The chip is a relief ground in so the last ball or two can be inserted before the cage goes in to space the balls apart. I always enjoy your videos!

I am still amazed you remember how everything goes back together once you have it broken down.👍

Mr. Matt, I have followed the reconstruction of Bulldozer D4 with great interest, it has been more than a year watching KZread, your excellent work, I am located in the city of Barranquilla - Colombia, I am a civil engineer dedicated to the construction of civil works, road infrastructure works, and earthworks, my sincere congratulations, a big hug.

Intense attention to detail. I'm positive your machine will give you years of work. Kudos from the Mountains of Western Pennsylvania 🇺🇸🇺🇸

It's great to see it in the final stages. You have a truck load of patience.

Once everything is connected, don't be afraid to turn the heater back on for a bit to help it keep running once it catches. The air movement will help keep it from overheating.

You definitely don't need to say sorry for the "garbage" this has been a wonderful series and can't wait to see this brilliant machine pushing dirt many thanks for letting us along for the ride, wishing you and all the other fans a great Christmas and New Year

I have a comment. Your doing bloody great. The longer the vids the better. Take ya time I’m enjoying it all. Good Onya.

Matt, the editing in this video is just outstanding! I got about 1/4 into it and made some popcorn as I knew it was going to be a good one. Like the last one on the big start, I'll be watching this one more times. Hope you don't mind. Ha

its not just your mechanical ability as many people have that ability it is your ability to look at a part and figure out what it does and how to put things back properly a unique gift few have. great videos watched from beginning and viewed your site from beginning. keep doing whst you do.

This is hands down the best series on you tube , content subject matter, process and creator. I am glad to see this coming together, I am hopeful you have another project lined up.

Hi Matt, it may have been a long video but it held me watching until the very end. You have done such a teriffic job so far i am looking forward to the next project.

I have watched all of your Cat D4 videos and all of your Hitachi EX 120 videos, and I always look forward to the next one. You have a great approach and always do a quality job. I'm looking forward to seeing the dozer finished and operational again. I'm keen to see what it takes to get the EX120 back to sound operating condition. I enjoy your sensible no-nonsense approach, keep up the great work!

You tube said short videos, I could watch this all day... Very cool project!

I second the comments below praising your effort. I will add that the "chip" in the old ball bearing is a filler notch. When the manufacturer needs more balls to reach the desired capacity than can be fitted by offsetting the races and slipping the balls in between the races, and then centering the races and adding the cage, a filler notch is necessary to add the extra balls. Presumably technology has improved since the old bearing was made, and the new bearing has the necessary capacity without the additional balls.

Your patience, knowledge, and skill are top notch……..such a great series 👍

Here is another suggestion that is really late. If you or when you smash your finger again and the nail turns purple take a needle, get it red hot, grab it with plyers push the tip through your injured nail right in the middle of the purple area. It won't hurt but it will squirt blood which will release the pressure and a lot of pain. I'm really impressed with the way you are taking on this cat. I drove my brother's D2 that was about the same age. It had a pony motor that you started first to get the oil pressure up before trying to use it to start the main engine. Thanks for sharing your journey with us.

Great job, I love your attention to detail without taking short cuts, everything done the correct way, keep up the great videos

Watching a new video from you is the best part of my day, aside from eating and sleeping. Thank you! Much appreciated…

loved the video. there was some good grunting performed. i especially appreciated how you dove into that hydraulic system rebuild without fear or reservation. if that was me, it would have been a mess. so, much respect!

This project sure has given you a education. You have cleaned and inspected and replaced and painted. No one knows this old girl like you do. You will have a knew old bulldozer when you are done. I would have given up a long time ago but you have far more skill than I do. Thanks for the video.😃😃😃😃

Congratulations 🥳🥳 to you. I've been watching all of your videos. And I'm amazed that you can take all of your equipment apart and put it back together. How in the world can you remember we're everything goes. You are a very smart man. Again congratulations 🎉🎉 to to you. I always enjoy all of your content. Keep up the great work.

I've really enjoyed watching this video series. Let's me live vicariously through your journey of taking an abused and severely worn dozer and making a very serviceable piece of equipment. I can hardly wait for the project conclusion and you putting that thing back to work. Please keep the videos coming.

Your doing such a fantastic job. Loving all your attention to detail! Can’t wait to see it pushing some muck.

Thanks Matt for posting. The dozer is coming to life in a big way. Great job!!!

I love your attention to detail, this is extremely informative, awesome job on the editing as well. Love this channel. Jay from central Pa.

Been watching your progress since you started on this dozer. It looks awesome and sounds even better. I am sure you have a great feeling of accomplishment as you are nearing the end of the project and l am sure you will be able to enjoy using it for years to come. Congrats on a job well done.!!

Thanks for making the videos of your work, I watched everyone since you recovered the CAT I have only ever rebuilt motorcycles, this is many levels over what I can manage. Regards Mike

You have a lot of patience and the ability to read prints, fun watching you 😀

The D-4 looks incredible now, can not wait to see rolling in the fields clearing what you need to be done. Enjoy watching your videos, you explain so much detail in them.

I watch a lot of these equipment repair shows on KZread, but it's always such a treat when you post a new one. You sure bit off a big chunk of work when you bought that cat, but I think it's going to be great when you finish it up, and way cheaper than a new or slightly used one. I don't know how KZread works. I don't know if you make any money at all from your videos (I hope so!), but you sure spread a lot of enjoyment by recording the work you do. Thanks for doing what you do and sharing it with the rest of us.

There's a lot of stuff jammed in that hydraulic tank and you managed to sort it out. Well done. A tip I learnt is when putting on something heavy like that cover is to cut the heads off longer bolts and cut a slot in the end. This means you can you can use a screwdriver to get then out later. It also works when you are lining up on dowels.

Was going to "tune " through this(video) pretty fast, but I stayed the whole time and I'm glad I did .Pretty interesting stuff, level of thoroughness impressive!

Good to see a man soldering his cable connections!

I would have thought those two unused lines there still would have been oil rings inside the valve body incase someone needed to use them for a attachment later on the cat is looking great thanks for sharing

I've been looking forward to another video. Thank you!

I've been really invested in this project, and watching it from the beginning... can't tell you how much I've been enjoying it. Absolutely superb work, well done.

Very nice video, starting watching a video yesterday that was over an hour long I quite after him taking for every talking about the different ways he could get in and out of a woods to recover a COE Ford truck. I got lost listening to him rambling on and on. Anyway great workmanship.

What a journey it’s been! Congratulations Matt.

Can’t wait to see this running. Have watched every episode and marvel at how you put it together again

Was patiently waiting for the current video to be shown . Was definitely worth the wait. Great job Matt!

Yes this is that D4-7U I thought I saw on shorts. Starts like a modern dozer now Matt . Good to see you continuing the same standard of workmanship as you check through the hydraulic system. I suspect it was assembled last time using grease as an assembly lube. Another item which turns to wood is Shellac gasket sealer. Anyway nice job. Made me want to buy a caterpillar.

I am glad you know what you are doing! I have watched this project from the beginning. Amazing!

Well done. Seriously I could watch you all day. Please do this full time. Well done!

Hi Matt,your videos are my favourite as I have an interest in earth moving machines because my Dad drove dozers and the first was a R4 that was converted to D4 when the R4 engine caught on fire. This D4 had the LeTourneau A frame overhead cable operated blade by a PCU mounted above the winch. Many hours I spent as a kid riding around on it with Dad. Keep up the interesting videos, the longer the better.

I work in technology on a mine site I spend some of my 12 1/2 hr days crawling over D10s and D11s I even got a limited license to operate a D11 used it once. But i still really enjoy this series working on an old D4 thanks for uploading this!

Glad your giving her the attention she needs and deserves.

I'm glad you painted it cat yellow instead of canary yellow like some of those parts that squash had for his 5j D2 series tractor

I was just thinking its been a while since I have seen an update from your channel. Thanks for the new material!!

Great stuff Matt it's looking good you are doing a great job the only thing perhaps that would make it complete is the original mesh grill in front of the radiator to help stop sticks etc from getting in there and blocking or damaging the radiator

You never fail to impress. Keep at it, will watch forever. D4 and beyond!

Great video. Regarding the pre heater you need to insulate the heater element from the steel intake pipe because if it shorts out from the heater element to the steel wall on the intake it will only work from the posetiv pole on the heater core to the short so it does not work up to its full potential. Otherwise great work

My uncle did logging in the Polk and Yamhill county area in the 1950's which is not that far from where you are at. I believe he had a D4 to do most of the work. Watching your restoration brings back fond memories. One thing I was thinking of as you putting the heaters into the intake is that another option would be wrap heater tape around the outside.

Great videos. You have incredible patience, skill and problem solving abilities. I have no idea what you do for a living but a wrench is not stranger in your hands. Its been a bit cool down here in Florence. Keep up the good work.

Great video bud! I have to admit that I had some doubts in the beginning as to whether you could get this going but over time you showed us all that you could get it done. Great job!

It's looking really good now.. Can't believe how long I have watched this series. I watch CEE Australia and one thing I have learned is you really do need to take the cylinders apart and clean them out even if the seals seem good. May as well replace them while you are in there. All that metal gunk has been coming from somewhere after all.

Great Job thus far!! Plz keep us in the loop on material cost along with labor hours. I’m sure you saved a boat load doing it yourself tho!

Amazing how far you have come with the crawler . And you are doing a Great Job ! Knocking off problems and issues as you move forward . Thanks so much for sharing. I hope the next video isn't far off ?

We're back so happy ☺️

Matt, Sorry about the big Hyd pump O ring getting missed. At least you saw it under the table in time to put it on before the first run of the pump. Really great work and almost there! Thanks.

Soldering battery lug connectors to cables probably not good! Not sure if acceptable for earth movers, probably not... per CFR (code of federal regulations) I suggest crimping in addition with your soldering. Battery leads can become heated hot enough upon prolonged starter engagements to melt solder and then slip out for the potential of a major short and potential fire. Crimping or swaging also ensures full connectivity and won't separate for the potentials. I am a retired NAMS-SAMS Marine surveyor active 40 years. In a marine application, your expressed method of connecting wire to lead would be ground for trouble....Thanl you.... love watching your progress from the beginning and enjoy seeing your progress unfold.

Thanks for sharing Matt. I've really enjoyed you taking us with you on your journey

Every time Matt says “ooh that’s heavy!” Drink!

You said in a previous video that you were told you installed the fan backwards. In someone else's video they said the fans were reversed depending on the season. In winter they blew front to back to keep the operator warm. In summer they were reversed blowing back to front to keep engine heat off the operator. I know nothing about this, but I'm sure Cat operators and mechanics of that era can give you the proper information, Great video series, happy I found your channel!! Best of luck.....................

Great video, I always enjoy watching the cat being worked on and looking forward to the next vid. Your patients is impressive, or the cutting room floor tells a different story 😛

I can't even imagine how much time it takes you to get a video ready. Awesome job!

The “chip” in that bearing is from the ball assembly. It’s ground in so when they install the balls you can actually get the last couple in place. Usually done on deep groove radial/axial load bearings.

Been watching you from the start cleaning up this dozer. It’s looking pretty good. I’m amazed at your patience. Good luck with everything. I can’t wait to see it run properly.😊

Just wanted to tell you how much I enjoy watching your vids. Very informative and interesting. Glad to see that you silll have a lot to do on the Dozer and Trackhoe. Looking forward to your next Video. Thanks.

Thanks for the video, Matt! I have been following you on the Cat journey and think you are doing a very good job. Comprehensive and careful work by you and always interesting! Stay with it. Looking forward to the next videos when you have a chance!! Your video editing is really great too!!

Matt, awesome work. On the vise, you can make soft jaws from tire rubber. Mind how you drill since rubber is grabby on bits, so dull the bit just a little. Edit: The pump shims might be salvageable with a body hammer and patience. Use a hardwood plank as an anvil.

It looks great so far. Thanks for sharing.

I've thoroughly enjoyed watching this Cat come together, Thank you Matt.

Great job Sir, love the series and your meticulous attention to detail

Love your work on the Cat, It’s amazing how heavily built everything is.

I'm really enjoying watching the progress your making and the way you edit the videos makes it easy/enjoyable to watch. Thanks for taking us along on this project and all the time/effort that requires. Can't wait for the next one!

Im obsessed with the perfection of this build!
