Repairing New Holland baler snapped crankshafts. Part 1
ฝัง
- เผยแพร่เมื่อ 3 พ.ค. 2024
- 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.

He said "I'm not a machinist" however he is and man can he solve problems. Can't wait to see the new line bore machine in action. cheers from Australia.

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.
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.
For a man who said he isn't a machinist you did a brilliant job machining those parts
The word gets out about this repair you are going to get flooded with New Holland crank shafts to repair. Interesting set up you have created.
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.
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!
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
Oliver is in good company with @OFW, @CuttingEdgeEngineering, @ICWeld
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,
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!
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 🤠
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.
The fact that you take the time to read the comments encourages viewers to leave comments, which no doubt helps the TH-cam algorithm to promote the video so you get more views and more subscribers. It shouldn't be long before you hit 50k subscribers.
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 👍
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.
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
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.
You say "I'm not a machinist". Well, yeah, maybe. But you're becoming one pretty fast 🙂
You're doing good. Keep going.
Oliver, you're really showing your problem solving skills. Brilliant. Cheers.
Congratulations on being able to get a boring bar setup. You deserve it. The jig looks great.
Excellent 3 dimensional planning and execution.
A pleasure to watch, especially with your explanations.
It's great to see you slowly expanding with more tools and a better set up.
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.
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.
Thanks! Who wants to see that parting tool get painted? Vote here
Thanks!
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.
Brother, you’re one helluva jig builder! And a machinist too!
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.
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
I hope you corner the market on the repairs to those crankshaft Ollie, waiting for the follow up.
Morning from across the pond Oliver. Great video and this will help out many in the same situation. Thanks for posting.
Thanks for sharing, looking forward to part 2. Stay well be safe, greetings from NE rural Ohio, USA 🇺🇸
Awesome project Oliver .. always very interesting to watch you work away at different challenges .. congrats on the NEW BORING EQUIP. CHEERS MATE 😎🍺🍺
Congratulations on the line boring machine Olly 🙂
Superb bit of logic in that jig! Excellent video too!
Phil
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
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....😅
Ollie , you do what you do . Don’t Doubt yourself, and your skills . Top job , as always
Well done . Again don’t doubt your skills . 👍👌
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.
Wow just wow, Oliver amazing job, Keep up the great work.

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.
That is a great idea 👍
Right... because paint is waaaay to difficult.
@@Failure_Is_An_Option In many places paint is a perfect solution, but Olly has enough rust to win an Olympic medal :)
Rust, yeah tell m3 about it, I just spent the day sanding rust off "stainless steel".
Excellent Ollie. Can’t wait for part 2.
I find jig and tool making really interesting because it's a step removed from the final result.
keeping secrets are we lol, happy u can resolve issues on video, nice human being, shhhh that might be another secret lol take care brit from minnesota USA
It's called intellectual property, this is valuable for forgers/would-be copyright theft! Well done Ollie, that is called integrity!!!
👌👍another good one! Young lad! Keep them coming!
love the work lads that think before they repair are in short supply. keep it up great to see your repairs
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.
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!

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.
Nice one Ollie, I’d keep hold of that jig when it’s finished , it could end up being used a lot !! 👍
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.
Quite a job mate, always a pleasure to watch your process
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.
Great work so far... Thanks for sharing this with us 😁
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.
If you enjoy Oliver's work as much as I do then you will surely like these as well - @OFW, @CuttingEdgeEngineering, @ICWeld,
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 😊.
@@TheGrimReaper1 The pre stuffer of a new Holland big square baler I have had the pleasure of removing a broken one and fitting a new one many years ago not fun.
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!
Another brilliant video Olly can't wait until next week
You do a fantastic job for a one man business
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 👍
Another Sunday gem !!! Thanks Oliver looking forward to part two.
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 TH-cam has put a few pounds in your pocket. :)
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 👍👍👍👍
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 👍
Yes! Snowball video!
Thoroughly enjoyed this one as I will the next, I'm sure.
Brilliant video. Excellent work as always. Best you tube hour of my week. Many thanks
Impressive work Ollie, Well done mate.
😂 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!
Nice job as always. Btw, you are definitely a machinist.
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.
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
Excellent suggestion!
Cant wait for Part 2
Love your approach to solving problems. A joy to watch!
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.
Looks like a Holland stuffer yoke to me
lookin forward to part dos
Nice new line borer, congratulations on that.
I thought of you last night when I was watching on fire welding using an Spower line borer!
Great mill work dude 👌
Thanks for the video. Eagerly awaiting part two :)
Always a good day when you get a new tool
Looking forward to Part 2, finishing the jig and repairing the crankshafts.
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.
Incredible work Ollie. You are doing precision toolroom work in a shed. Good on you. You are a master craftsman. Keep it up mate👍
Hello from TEXAS!
Hello there!
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!
Great video man, I hope you can use that jig for future work, lol. People don't realize how much time and work go into a project. Looking forward to part #2..
I wouldn't worry to much about your turning skills u will find the tools u need as u go along u got it done that's the main thing ...I also think u maybe over thinking the that jig it will work absolutely fine ...be looking forward to the next video see those new tools at work...well done keep up the good work...
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.
Thanks for the videos.
Hey there! Great videos by the way, however, I couldn't help but notice your welding process of using solid wire MIG/MAG for most of your projects. It's great for structural and farm repairs (and cost)! However, for high-quality materials like the round bar in your video, consider switching to a flux-cored or MMAW filler wire/rod and a full penetration weld prep. This could help reduce imperfections in the weld that might lead to failure down the line. Just a thought-I suspect the original failure might have been due to a weld defect like porosity or lack of fusion migrating into the parent material. Hope this helps!

Another great job
Hello from Texas,USA. Great job on figuring out the alignment fixture. Fyi ,That anchor lube works well on stainless steels also. Great job as usual. Cheers
Thats the most crude crank shaft ive ever seen but yiu sir mad it a gem
Great work as always Oliver. 👍👍👍
Didn't get a true size perspective till you placed it in that fixture, that's a chunk of metal.
What a top man you are. Well done Oliver on another excellent video.
Brilliant vid again top man 👌👌👌👌👌👌
A very well-thought-out jig! I've had many years welding experience and making jigs for various projects but no maching experience, I can see no reason at all why it won't work perfectly as-is. Looking forward to Part 2 to see how it all works together. My guess is that you'll get this job done, no problem! 👍 (ed. for sp.)
Really awesome content. Thanks for posting.
Amazing work keep it coming
