Repairing New Holland baler crankshafts. Part 2

- In this video I finished the job of repairing the New Holland baler cranks.
Firstly the jig needed line boring to size, to do this I used the new S power line borer. After the 2 end supports were done, I transferred the jig onto the Huron milling machine to bore the centre support to size. This completed the jig.
Next up I test fitted the crank into the jig to ensure it fit and also to get some measurements of the overall length. The old journals were then plasma gouged out and cleaned up with the grinder before refitting back into the jig ready for the repair. The new journal was preheated and then welded around.
Same process again on crank number 2.
Lastly I fitted some bearing onto the cranks to check the runout, there was some runout but well within a usable tolerance.
Hope you enjoyed the video.
Thanks for watching.

Thank you everyone for mentioning me. I do like the S power system and the more I use it the better it becomes. And another great video from Snowball Engineering! The world would fall apart without guys like us!
Too true buddy
A good shout-out to On Fire Welding for taking the time to thank the people who mentioned him here, it's very nice to see that some TH-camrs appreciate their audience. Too many see it as a way to increase their profits and care little or nothing about the people who watch their channel.
Two of my favorite YT creators, OFW and Snowball!!
@@Watchyn_Yarwood You have impeccable taste, my friend.
Oliver, you should be proud of your work. You are so patient and persistent in achieving perfection. Not many people these days would be bothered to go to such lengths the repair that crank. I'm surprised you don't have a lot more subscribers.
Your such a perfectionist and my favorite ahead of IC weld, I did start off watching Cutting edge but the excessive F&C words Lost Me! The Farmer/ Contactor Must Grease Regularly, Right.
Completely and absolutely agree mate
@@fredscheerle7592 Do as I. Stop the vid at the end before it fades to the outtakes.
Full credit for not editing out when you make a mistake, that's the difference between people actually doing real world work & the TH-camrs with an editing team who show then making perfect projects everytime in immaculate workshops that you can tell have never been used to any real work.
Also even Clint at C&C Equipment didn't splash out on the same Line Boring kit as Kurtis I think he went for some Italian machine.
But Clint & Kurtis can justify spending out on expensive kit with the heavy equipment they repair on a weekly basis £15k vs £3k is a massive difference for a small one man workshop.
The accuracy of aligning any crankshaft assembly is a mental fairyland for us weekend warriors ! Your explanation is thorough beyond belief !
Great job. Maybe a clip of the baler in action whenever it makes it to the field and show the fruits of your labour.
There will always be people who can do it with their eyes closed and hands behind their backs🤣 I wouldn’t even mention them, don’t give them the attention. And regarding balancing I think people don’t understand that this is farming equipment and not a nascar race engine crankshaft. Different levels of working speeds and tolerances. Really enjoyed watching this, that jig worked perfectly and you should be proud of the skill set you have.
That crank only runs at about 300 rpm and is under constantly variable loading as the crop passes under it hence why it does,nt have any balance weights on it from factory
Some of the runout on the crank could be attributed to the aftermath after the crank failed while it was operating inside the bailer. Considering how it will be used in the field (pun intended) I think the repaired crank will be fine... Ask the owner for feedback once he gets them re-assembled and operational, even if it's later in the season, me and the your other 42k subscribers will be more than interested :)
Right, could be slightly bent. And since that is not a new shaft he is measuring, could be just wear on the journal.
Oliver, you underestimate yourself. Your work is outstanding, I only wish there were more people like you. You are a craftsman,well done. Best regards John, p/s keep the videos coming.
Great work on getting the alignment as good as you can, probably better than the manufacturer. The comments above balancing that are comical, obviously thinking it is an engine part, possibly connected to connecting rods or the like rather than driving a set of fingers rakes that in addition to the straw can have whatever is lying in the field thrown at them, as well. Makes as much sense a suggestion that a tractor wheel needs putting on a balancing machine, maybe at the local Kwik fit 😁
Hi Oliver, Once again your attention to detail and desire to produce the best result possible is admirable, the time and effort you put into building the jig paid obvious dividends in the quality of the repair, I sincerely hope you get more of these to repair, it would be a shame if you did not get the opportunity to make more use of the jig. Your absolute deadpan delivery of the "Would be rude not to buy one" line had me in stitches, classic Yorkshire humour at its best.
Brilliant work from planning to execution. Thank you for taking us along with you on this.
That crankshaft will be fine. People don’t realize it isn’t an engine crankshaft with very tight tolerances. Plus it doesn’t look like it was balanced from the factory. Very good repair.
Mistakes, overcome, is what separates the experts from the novice.
Brilliant vid again Ollie, had to chuckle when you said about that commenter who could do it without a jig,probably without welding it as well !! 👍
I don’t think that commenter knew how crankshafts work.
As woman I love your craft,and your video,very inspirational to others who doing the trade,women,men.
.3mm tir in a welded assembly, bloody brilliant 👏👌
Agreed. And he doesn't rate himself as a machinist - rubbish. Many machinists could not have worked this out. Sure they can make an item off a drawing but to design it from scratch and then devise a method to calibrate and machine it is above many machinist's pay grade, knowledge and skill. Retired fabricator/machinist/mechanic.
That’s a lot of work went into that Ollie , hope you get plenty of referrals to use the jig , make it earn it’s keep😂
Don't worry about bout some keyboard warrior that has no clue, looks great, you did exactly as most shops would have done with the jig!! The run-out could be just old journals having wear on them, no telling what happened when it broke in-half!! Keep up the great work 👍 👏
Loved the video and the approach to tackling a tricky job.
This was undoubtedly a masterrepair you can be proud of, Oliver. For welding different workpiece materials or shafts of higher tensile strength, we use the Ugiweld 4370 wire with 98argon gas mix. They probably used similar filler material at CNH (or stainless 309). They undoubtedly also had the deformation after welding in the factory, they may have 'straightened' this out afterwards in the area of the square tube with the flame torch, like Keith Fenner does when straightening shafts with the local heat pool shrinkage technique Thanks for the nice content video!
Wow! Another great piece of work and video! Keep up the great content! Young lad! 👌👍
Great job. I think you could build just about anything.
You have developed a nice presentation style and your videos are well produced and edited. You are a pleasure to watch.
Thank you very much!
At least your set up for anyone else with broken Bailer cranks
Another cracking job bites the dust.
Nice fix. Looks like it will do the job. That thing is going to bend and twist like a wet noodle anyway with 3 journals and only supported at the ends. It may well be that they run-out more than that from new, contributing to them breaking. Like you say, it's not an engine crank. Time will tell. I bet there aren't many who would take the job on.
The way it's designed in the first place and the way you have it spinning it's pretty much balanced spot on. Some people don't really understand what they think they are talking about ;-0 ;-)
Ing they could do it without a jig and actually doing it is 2 different things. Its the difference between someone who takes pride in there work like yourself and others who dont care but just weld. Great Job . Looks spot on. Regards Andy Australia
Don't question your work as it is very good, I have been doing it a long time and that is a good fix.
They are not that good NEW
Probably better than when they were new!
Phil
Ollie simple rule of thumb " It's a Timex not a Rolex " If this is not close enough go to the dealer and buy a brand new one! Bet you money it is not this close! Look at the cost saving! Keep up the great work !
New ones aren’t available anymore so it’s this or scrap the machine.
@@snowballengineering They could be! You've done all the hard work. The 4 bits of box and 8 plates would be easy for you. The only difficult bit left are the splines on the input, but if you did the "reman" thing and took the old one in part exchange for the new, you could probably reuse most of the splined shafts from the trade-ins.
Of course, I've no idea how you would market them; but you seem to get enough come your way, maybe word of mouth would be enough to keep your jig in use.
This project is very interesting and involved ,but it's great to see you solve the problems and succeed , Keep up your good work
The construction of the jig was a first class piece of equipment a true professional engineer
Lots of work there. Thanks for the videos.
Fantastic job on a brain teaser. Thought through clearly, well executed and I’m certain well within tolerance for the application. Thanks for taking us along!
Nice work Oliver. Watching from Eastern Texas.
Excellent job! I think you nailed it when you observed that the stands had movement when you were measuring the runout. It is likely bang on.
I think you now qualify as a machinist.
Best work ever. 👌👌👌👌👌👌👌👌👌👌👌👌👌
Morning Oliver, have a great day buddy
You too!
I'm impressed. Very impressed by all the engineering. I don't think any other shop would have taken the challenge, but told the customer. Go buy the factory.
But not Ollie, hold my beer.
And stand back😅
Great job! Don’t worry about the other commenters. You are the one who had the tiger by the tail and done an excellent job ! Keep up the good work and Be Safe!
On Fire Welding has several line borers, he’s just got one of these and posted a great video just yesterday about it, seems to prefer it to the hydraulic Climax as it’s got good torque and is quieter. OFW used the stick out measure off his climax, I’ll bet you could get hold of one, or make a reasonable copy..
Great to see the businessman in you investing in your business, you will go far, you obviously know how to pace yourself in your working future. Power to your elbow, I’ll bet your Dad is so proud of you, I certainly would be, but like most dads they never show it.
Another fantastic and informative video. Ignore the desktop engineers😄
im not an engineer and have never used a line borer but those initial cuts looked pretty impressive the amount of material it was taking out
Those crankshafts are a repair shop nightmare. I think your repairs are spot on. I am impressed with the S Power line bore equipment, quiet and enough power to handle the task. I look forward to your videos and Thank you.
Sunday morning. 8.00, means only one thing, Snowball time again
@johannesfiftyeight9287 , anytime is a good time for Snowball 👍🏻
That lineborer is pretty impressive for an import, 4mm depth of cut? 👌🏻 jig turned out fantastic, Olly. Your problem solving skills are just getting better and better 😊 The other commenters do make me laugh, I’d love to see them balance that 😂
Oliver, I agree about the runout as you said it’s not going into an engine. Would be interesting to know what it is on an original piece! 👍🏴
I'm not sure whether you watch Clint's TH-cam channel at C&C Equipment? He too has a Chinese (I think) line borer and the motor on his machine also gets very hot. Incidentally, he watches Kurtis at CEE and is also in awe of his (very expensive) line borer. I love your videos and the refreshingly honest approach you take when making mistakes and learning from them. This is another great video, thanks for posting such interesting and educational content!
I say, I have never seen a break on a shaft that looked anything like that crank. Quite interesting to say the least.
Beautiful work as always. What a tricky job to do. Way beyond most people’s capabilities.
If the farmer complains regards to vibration when running, try to cap off the 2 higher ends(when in the jig) and grind off some of the bottom of the lower ends to lighten(when in the jog) to fine tune the balance. Increase plate thickness to increase weight accordingly, but doesn't look like a lot would be needed. Try tacking on random scrap to experiment.
Some cracking work though none the less! Videos are also getting better and better.
It doesn’t look like it was balanced from the factory. Didn’t see any weights or spots drilled for balancing and he didn’t mention seeing any. I think they have a vibration dampener on them anyway like a balancer on the front of an engine.
Those two crankshafts came out well. You couldn't have got them any better than you did. For what they are. they are plenty accurate enough. It would be interesting to get a non-broken original crankshaft and test the run-out on it. You'd likely find it's no better than the repaired ones. The fact that this crankshaft turns much slower than an engine crankshaft, you can get away with a tiny run-out like that. If it was an engine crankshaft running at 5,000 RPM, it would be a much different story. That much run-out would result in self-destruction.
Oliver, once again, great problem solving and building skills. Whenever I had work done, the better shops would clean and paint rusted surfaces giving a proper finish. It would always impress me when shops would do that. Cheers.
I truly love watching your channel oliver
Great job Oliver, Kurtis would be proud of that repair. Keep up the good work and thanks for sharing with us.👍
Seconded!👍
Just because others do it doesn’t limit you from making improvements for your operations. Your creativity and intuition are your better assets.
As always…..GREAT JOB!
Not being a machinist, you’re pretty good. You use your brain and solve the problems. I’m a fan of Cutting Edge Engineering also and you have the same attitude. 🇦🇺👏👍🏻
Cracking job again Oliver you really could do to get an overhead crane system even to just assist with moving things to set them up on the machines !
Don't be overlly concerned on the motor temperatures. The motors are Servo motors and they are designes to run at high temperatures. I repaired them for 25 years and we used to load test them and get them up to 100 C.
All that good thinking you did made the jig turn out great, a real asset you got now. It looked good when you showed the machining on the thermal image screen. Thank you Oliver, a good job you did, and most entertaining video again as usual..
Brilliant work! I only hope that the price of a new crank from New Holland justifies what you are entitled to charge for all the work that you’ve put into those two alone. Something tells me it does based on the price of parts. Lord knows, you deserve to be compensated for what you’ve put into this project.
I wouldn't worry about that tiny bit of runout, for the reasons you mentioned but also the loads in use as varying amounts of hay/straw go through the machine. Sometimes big heavy slugs go through, other times just a wisp of material. The loads on the crank will change a lot due to load. Nice job! Cheers!
Ollie, you are a genius. That looks as good, (if not better), than the original, Considering it's for a baler, that is, I would say, perfect for the job. As they say, only time will tell, hopefully you will have retired before seeing these again (except when the others go that is). Thanks for teaching me, what I don't ever want to work on! Given that I 'm retired myself, that will be never. Thanks from rural W. Berks.
Your solution is as good as the factory piece , maybe better . Very fine work .
Better than factory 👍🥰
Bailers tend to shake all over the place. Not sure bailer and balance should be used in the same sentence.
While that jig was setup in the mill, I think that I wouldn't have been able to pass up the temptation to center drill the boring bars. Might be useful at some point to check for runout or it could just be my OCD making a visit.
You probably could adapt your jig to an engine stand easy enough. You will either get more of those cranks to repair or never see another one.
I guess your more Snowball Precise Engineering (SPE). With making a crankshaft jig and measurements always have to be precise. And always looking forward to your next instalment.
The quality of products out of China has improved a lot over the years. However, this depends on the actual product and just where it was made. So there's good quality products and not-so-good products. It's a case of choosing what's right for your needs at the time. Hopefully this line borer is as good as it looks.
Sorry Oliver, i miss a few.
I was in hospital.
Always a pleasure to see how you approach things 👍🏻
You should build a cart for the line borer that holds control box and all the tooling so it is all in one place and it will mobile.
It's going to work great!!! Not to worry, the manufacture of farm equipment are not that picky.
Great job again as usual Ollie, from an engineer to a ‘non-engineer’ 😂😂😂 your not fooling anybody buddy! Your task processing and mechanical skills are a credit to you, well done again another great video 👏👏👏
Your repairs are entertaining. Your repair jigs are absolutely amazing.
It's just a pleasure to watch a man do precision work!
Thanks.
Lol "be rude not to buy one" that made me laugh, wonder would it work on the wife for something 😂. Great work as always
Dream on Buddy, you wont get away with that one. LOL
There’s only one way to find out! Just don’t blame me when you get in trouble 🤣
Got the coffee ready just in time!☕
Me too
@@chipperkeithmgb whiskey for me!
@@levitated-pit bit early in England 🏴 for that had a couple bit later 🥃
@@chipperkeithmgb nah mate, its never too early in nightshift England. chuckle
I did wonder if you watched CEE. 3000 vs 15000 is agriculture vs precision. You bought what was right for the work you do and it looks a fair bit of kit for the money. Great channel keep up the good work.
Can't see it being that less accurate, ground steel bar and self centering bearings will be exactly the same so Olly can buy 5 for the same money?? Makes no sense buying the expensive one, maybe just fashion or wasting money for tax purposes they do tend to throw it around at cee.
Awesome job Ollie! You showed your true ingenuity on this one.
Ur engineering abilities are top notch, Ur deductive thought processes are key. Keep up the fantastic vids !
Greg at OnFire Welding just got this machine and he has a Climax as well. He mentioned his second job was better than the first as he got familiar with the tool.
It’s Sunday morning and Oliver’s latest video is out time for a coffee. Absolute brilliant work and sharing your thoughts. Love it keep up the great work mate
Ideally, both units badly need balancing. Great job Oliver. Nice new Toy to play with.
I love the work u do and love watching u at work
Fantastic result with so little runout. Probably less than factory. cheers, Butch.
You'll have to give us a report on how this worked for your customer. Good stuff sir.
Wow Oliver, What a amazing job. Keep up the great work, From kiwi land.
Incredible work again Oliver ,ingenious answers to problems 👏 just one small comment _ have a tidy up now and again or treat yourself to a toolbox mate 😅
All i can say is holly WOW!!!! that is awsome !!!!!!!!!!!!!!!!!!!!!
Given that it is used in a baler for the hay forks I would imagine that its rotational speed would be a little less 60 RPM, probably more like 30RPM I imagine. The shaft wobble at that speed would not be as significant as the out of balance IMHO. The break to me looks like it was caused by the out of balance issue as it looks like the fracture worked from the outside in with an even pattern. It was a pretty clean break. Given that you have an idea of how much out of balance it is would it not be prudent to weld some counterweights on it in a couple of strategic locations. 3.5KG even at 40RPM is a huge amount. Thanks for the video Ollie and all the very best to you. You are one clever bloke.
Great one Oliver - you’re a natural inventor and I hope you can find time to pursue ways to improve our lives
You could use an engine hoist using hoist to lift in place and you can organise all the tools for that awesome borer
Nice work
You’ve done a hell of a job boy 👍👍👍👍👍👍👍👍that’s why we watch and try to learn! Even though most are know it alls there still learning just won’t admit it. Thanks Oliver.
Oliver, there should be a max. temperature written on the motor, for these servos 90°C or even more are normal. The gearbox is a worm gear, efficiency is lower than gearboxes like used in cars, that's why it gets warm too. So don't worry about the temperatures.
Very nice job btw. I like your skills on the CNC and i very much like the way you solve problems.
A job well done ,almost impossible to be any more accurate, great work !
Congratulations! This was a very hard job and you did wonderful.
Great job, showing real work getting done right.
It looks good from here! Thanks for your time and skills!
Mighty fine repair, Oliver! Put the baler back together and head for the field! As others have said, would be interesting to hear an update on how the repair is performing in the field.
