Repairing New Holland baler snapped crankshafts. Part 1
Ғылым және технология
In this video I start the job of repairing 2 baler crankshafts that have snapped.
Firstly I start by cutting 2 lengths of 75mm bright round bar to use to make new journals. These are then turned down to size in the lathe with a bigger radius to hopefully improve on the original weak point. The shafts are then parceled up and sent off to be hardened and tempered to match the manufactures specifications.
Next up was to start making the Jig that will be used to hold the 2 halves of the crankshaft inline while the new journal is welded in. I cut some 80x80x6 box section to use as the main frame then flame cut some rectangles from 40mm plate to use as the clamps.
The 3 top halves are drilled with 4x 12mm bolt holes and the bottoms are drilled and tapped to M12 to match the top. They’re then bolted together and a 40mm hole is drilled and reamed in the side which will be the starting hole for aligning to weld onto the frame and also to line bore.
The frame is then welded together and the crank is temporarily placed in and clamped down to see where the middle clamp will need to go.
After some over thinking its decided the third clamp can be on the same centre height as the 2 ends. Some more box section is cut and tacked on then then fully welded around.
That’s all for part 1.
Hope you enjoyed the video. Thanks for watching.

Hello Curtis & karen lots of laughts
I look forward to Sunday morning watching you solve and repair old machinery to help them live on for a little bit longer instead of being sent to the scrapyard to be turned into baked bean cans. without people like you farmers and other small businesses would have to buy new machinery that is not cheap you are helping them stay in business that’s why this country needs people like you. thank you.
For a man who said he isn't a machinist you did a brilliant job machining those parts
I always look forward to your videos every Sunday morning, I know you mentioned Curtis at Cutting Edge Engineering, you both are very good at what you do

I'm too far from him, but this has indeed made a solution for peeps around my brother's farm that operate NH units. Some of them have taken to buy other units to scavenge for parts. Kinda douchey of NH to do this to be honest. They should've owned up to their mistake, this isn't just "wear and tear" this was bad design from the get-go. Nobody in their right mind would expect this to last. NH either screwed the pooch or did this on purpose.
Oliver is an excellent problem solver, what I see he saves his customers lots of time and money. He doesn’t give himself enough credit. Great work Oliver.
Absolutely amazing work! The ability to problem solve and work to such high standards without a multi million pound set up is way more impressive than just having a few years experience on a brand new lathe with all the exact brought tooling!
It’s funny how here in the uk The real top quality work happens in places like this by people who have a passion for what they do. Most of the work is created by the poor quality of the original product 😢. Great to see you take pride in your work you do. My father used to tell me it’s not a problem it’s a challenge you will find the answer to eventually. Keep up the great vids.
I am a machinist and your doing a pretty good impersonation 🤠 I learnt (at machinist school) that shafts with a hole down the middle are actually harder to shear off than solid shafts. If word gets around the other farmers that you can fix these things you may want to consider putting a hole down the middle. The size of the hole doesn’t matter that much as the shear originates from the centre so you remove the starting point. Spiral and Gun taps are better for machine use. You are right to start the straight fluted taps in the machine then wind them through by hand snapping off the chips as you go. Spiral taps the chips come out the top of the hole and gun taps the chips are pushed ahead of the tap so not a lot of good in a blind hole. Generally gun and spiral are called machine taps.

Another thought might be to have them case hardened rather than through hardened and tempered, Another thought, from a complete amateur, might be how is the welding going to effect the hardening, might it actually cause a brittleness in the pin. Another another thought is the design flawed with odd web support causing a bending leading to a fracture.

The best high performance crankshafts are hollow journaled. Doug Kidde, now Arrow precision make and sell these from about £5000 but I don’t think they have bailers listed in their products Arrow one of those quality British engineers, at the heart of a huge industry of motorsport. Like snowball, he started in a shed.

@@tomtdGreat example. I didn’t know they did that. It would be good to have a close look at the end of the sheared pin to see the pattern. I was thinking of a drive shaft as an example. They are always hollow and it’s not just to reduce the wait. Perhaps Mr Snowball will put a drill through 🤠
I have been a machinist for 37 years and you are doing fine, making tools you need to do a job is part of it. If you can buy the tools thats great but if you can’t just remember gotta do what you gotta do!
The fact that you take the time to read the comments encourages viewers to leave comments, which no doubt helps the KZread algorithm to promote the video so you get more views and more subscribers. It shouldn't be long before you hit 50k subscribers.
You say "I'm not a machinist". Well, yeah, maybe. But you're becoming one pretty fast 🙂 You're doing good. Keep going.
Congratulations on being able to get a boring bar setup. You deserve it. The jig looks great.
How could we not enjoy that video Oliver, watching you working out how you are going to do the best possible repair job on old machinery like this is fascinating,
Good project, well thought out jig. Waiting patiently for part 2. People doubt the effect a bad radius can cause, this broken camshaft depicts it very well. Be safe and well 👍
My mate is an hgv/plant fitter every time he struggles to do a job have to remind him the guys in India do it with a big hammer and safety flipflops . Exhalent as always Oliver

Excellent problem solving, Ollie. Always look forward on Sunday morning to seeing your videos.
Brilliant. Well-designed and fitted jig to work with that shiny new boring kit! Looking forward to part 2. By the way, for a guy who is "not a machinist" you do some damn fine lathe work. Thanks, Oliver. Cheers
It's great to see you slowly expanding with more tools and a better set up.
Hello from West Texas. I am so pleased to watch you solve problems and help farmers and others. You are a true craftsman. More videos every week would be great. Take care.
thanks for sharing with us. Watching you quietly problem solving without fussing and faffing about is somehow very enjoyable and strangely relaxing. faffing around is "spending time in ineffectual activity" for overseas viewers. Sometimes known as twatting around in the English language....😅
Interesting job, the jig is a bigger job then the crankshaft repair ! Hopefully more of the same job will come in to re use the jig. The new line borer looks to be a nice addition to your shop. Thanks for sharing your work week. Brian from South Yorkshire.
Excellent 3 dimensional planning and execution. A pleasure to watch, especially with your explanations.
Oliver, you're really showing your problem solving skills. Brilliant. Cheers.
A great video as usual. You say you're not a machinist but you do a fantastic job knocking spots off some who say they are machinist's.
if the end result is what you want to complete the job then that's good enough. Don't knock yourself down your doing brilliantly
Taping the cardboard box was awesome, then cutting out a broken tap with a plasma cutter really got my attention! But unveiling the new line borer totally stole the show!! Can't wait for part two! BTW, the hoodie you sent is absolutely awesome! Love the content bud, keep it up! Roger from Calgary.
I hope you corner the market on the repairs to those crankshaft Ollie, waiting for the follow up.
You certainly get some unusual jobs in and this isn't the first time you've had two of the same job come in for the same repair. It seems to be a problem with parts no longer being available for older equipment, so it often means replacing the equipment if parts can't be made or repaired. But as usual, Snowball Engineering to the rescue to save yet another old machine from the scrap heap and get it back in action again.
Superb bit of logic in that jig! Excellent video too! Phil
Well a great start for a Sunday. Nice that you got 2 in 1 go rather than doing the 1 then another turns up a week later .. great idea on the design of the fixture frame I'm looking forwards to your first run with the new line boring machine I'm sure on fire welding did a video on this a few weeks back . Said for the money and quality it was a great tool . Have a great bank holiday Oliver, see you in part 2 thanks
The North-east of England has a long and proud history of engineering. The future is assured with 'problem-solvers' like Oliver. Great stuff as always.
If you have any letter stamps it's a good idea to stamp the ends of all bar stock whenever you receive it. Then re-identify it with its grade as you cut a length off the bar. It takes a few minutes, but the next time you need a specific grade of steel it will be much easier to identify.

A lot of jobs have more than 1/2 the time spent on jigs and fixtures. And thats an impressive jig, hopefully it will be put to good use in future. I must admit that I was surprised to see the new line boring kit. I always thought that your shop made borer seemed to work far better than you'd think it would. But onwards and upwards as they say.
Yes! Snowball video!
I have no idea of the potential market for this repair, but you'd like to think more might come your way to maximise the return on what you have had to invest in this thus far. Thanks for posting and I look forward to episode 2.

Awesome project Oliver .. always very interesting to watch you work away at different challenges .. congrats on the NEW BORING EQUIP. CHEERS MATE 😎🍺🍺
Totally agree that you are a problem solver and a pretty good machinist. What I hope is that you are getting enough money for your work. Yes, the farmers need a good and economical fix for their machines. At the same time, you need to receive enough compensation to pay for the new toys and make a decent living. Both we and the farmers would not be well served if you end up going belly up. Don't undervalue your work.
Quite a job mate, always a pleasure to watch your process
You're not a machinist? Well, you're doing pretty well with all the machines in your workshop. You always get the job done and done right, no matter what the job might happen to be.
It's really annoying when a tap breaks, because it's very difficult to remove it. You can't drill it out because it's hardened, but you managed to get it out with the plasma cutter. That was some feat!
An interesting job that young man. It is to be hoped that whatever brand of baler that crankshaft came from, there are plenty out there that will suffer the same fate so that you can make more replacements to help pay for the investment in building that jig. Still, good to watch and see how you figure stuff out.

I think that baler crank is actually called a ”stuffer” . It feeds hay or straw or silage into a chamber and after several packs or slices are gathered up to predetermined pressure the big ram pushes it out into the bale chamber. But don’t quote me on that 😊.

Brilliant piece Oliver! Where would we be without guys like yourself!? That baler would be scrap without your input and who can afford that kind of expense especially in the economic climate right now! Cracking stuff fella 👍
Thank you for sharing, another sunday morning who start with my coffee and your your video, i am glad, i learn a lot and another good project, have a nice sunday 👍👍👍👍
Another interesting project. Thank you for bringing me along to watch as you noodle your way through to a successful repair. I wonder if Mr. Farmer will take more care in the future to keep these joints properly greased? With the amount of dust and debris these shafts and bearing blocks operate in, my hunch would be fresh grease at the startup of ever shift. That would not be overkill. Congratulations on your new line boring outfit! Good for you. I hoped KZread has put a few pounds in your pocket. :)
I find jig and tool making really interesting because it's a step removed from the final result.

Hello there!
Impressive work Ollie, Well done mate.
Excellent Oliver. Please take more care of your hands when clearing lube and swarf. You'll wish you had used brushes and gloves in years to come. Barrier cream is not perfect. Take care of yourself mate. Another really good video - looking forward to part 2!
Nice job as always. Btw, you are definitely a machinist.
Safety flipflops, a coat hanger wire electrode , and you have a repair that looks just like a real repair . Coat of paint, and send it out. In a time before cutting inserts, we spent an entire semester grinding cutting tools, good to know how to do it. The biggest thing I notice precision machinists ALWAYS do is faceoff everything they are going to turn. Regardless of what it is, or is going to be, when a piece of work gets setup in the lathe, it gets faced off.
You do a great job figuring things out Oliver. I can't wait to see how your new line boring machine works out for you. I'm still impressed with the home made unit you made. Hope it makes your life easier because you work plenty hard enough. Great job with the video again Oliver.
Enjoy your content. H-8 is a dimensional tolerance. A good surface finish could easily be applied with a finer grade emery paper after heat treating. Save yourself some money. It's great to see you work these things out in your head. Keep it up.

They are being ground because they will be hard ,so easier to grind than turn ,it shouldn't cost much if he goes to the right place. probably could get away with turning to size before hardening for this application but might as well do it right.

Thanks for the video. Eagerly awaiting part two :)

Brilliant vid again top man 👌👌👌👌👌👌
I had absolutely no idea what you were on about until I saw the jig finished and then it all made sense. Takes some brain power to come up with does that lad 👍
Nice new line borer, congratulations on that.
Always a good day when you get a new tool
Amazing work keep it coming
Didn't get a true size perspective till you placed it in that fixture, that's a chunk of metal.
Cant wait for Part 2
😂 Morning 🌞! I was sitting here, cringing, watching you tap those blocks out on the mill! I learned my lesson years ago! Just start the tap using a centre pin to align it perfectly and then tap them out by hand! 🤣🤣 Broken taps are a pain! And now I know what the new line boring machine is for! Curiousity satisfied! Great to watch as always!
Really awesome content. Thanks for posting.
When you were talking about the claws you made your hands claws, nice touch that. To know the baler claw you must be the baler claw.
write the make and model of the baler in the name of the youtube clip so more people can find you if they have the same problem. when they google broken crankshaft for baler mod xxx

another great show.you are amazing. thanks for your time again. see you next week.
Looks like there's a lot more work in making the jig than repairing the crankshaft. But with having the jig made, it means that when more of these broken crankshafts come in, you are set up to repair them. Hopefully they don't break in a different place, which would mean modifying the jig to suit.
From my vantage point, some 3000 miles away mind you, it appears like a lack of a proper radius is what might have caused the failures in the first place. For the tapping head Tommy Bar, May I suggest that you make a post that goes into a T slot and sticks up high enough to suite you. that way it can be positioned anywhere. Or even something that bolts to the back of the vise if there are some tapped holed back there to move the jaw to the outside. I like the fixture idea. I will be interested in your thoughts on S-Power and it's build quality. I hear they are inexpensive as far as boring machines go.
Great work as always Oliver. 👍👍👍
Impressing work as always Oliver

Oliver, to avoid using the parting tool you could have cut the shafts down in the bandsaw then faced them. Dave
Hi Oliver, never doubt that you are a machinest, plater, welder, and all round craftsman, and a damned good engineer in my book. This job could be a right puzzle to a lesser man, but you've worked out what's needed in a jig to make accurate alignment possible , thereby creating as good a repair as you can, which is what you always do. I look forward to part two, thanks for another interesting video mate, stay safe, best wishe's to you and your's, Stuart UK.
Thats the most crude crank shaft ive ever seen but yiu sir mad it a gem
Looking forward to Part 2, finishing the jig and repairing the crankshafts.
nice job as is the norm for you over engineered but better that than under and have it bend this way you will have this jig for life and i am sure there will be other times when it is needed and with slight modification can be used for other crank shafts and such also good to see you are reaping the benefits of your hard labour and getting some more toys in the shop not that the home made one was not good it was doing the job for sure now you have moved up to something a bit better keep the videos coming mate just like every moment of them also i did not think you would have got that broken tap out but shows with a bit of perseverance one can achieve Cheers
I thought of you last night when I was watching on fire welding using an Spower line borer! Great mill work dude 👌
