Rebuilding gearbox mount on New Holland CR980 30ft combine header

- In this video i repair a badly metal fatigued knife drive gearbox mount on a New Holland CR980 combine header.
It had had many repairs previously but had gotten to the point where there were too many cranks to reweld. I decided to cut out the old metal and replace with new.
It seemed never ending, and i found the repair quite difficult, it wasn't a very pretty repair but should be stronger than the original design.
Hope you enjoy the video.
Thanks for watching.
I think most shops would have turned the job down rather than put in the effort you did. Excellent work, I love watching you. Thanks for posting
Got to agree
Fantastic video, really daunting with so much cut away,.......... any more and it would have been a 'Trigger's Broom' situation.
With many of your vid's, would love to see it working, just a comment. Cheers.
The challenging projects make for a good RUclips video tho.
I was going to say the same exact thing
I’d probably turn it down if I had another one the same to do 🤣
"I don't really know where to start ..." every single person watching felt the same way
Snowball...the best fabricator/engineer on RUclips.
No pretence, no BS, just down to Earth problem solving...what you see is what you get, including mistakes and cockups.
It's so refreshing to see a guy ..think, analyse and overcome difficult one off problems.
Snowball....keep the vids coming! 👍
Thanks! I don’t know about the best but I try to keep it real.
And editing decisions
@@pedromorgan99... no said that there was no editing at all.
Your "never say die" approach to fixing under-designed equipment is a treat to observe and follow. Farm equipment manufacturers should be required to follow your site.
The job of manufacturing engineer is to figure out exactly how thin the steel can be without causing failure in over say 2% of cases. Not understanding this, I am very skilled at breaking such equipment. Just ask my former snowblower.
Clear lack of maintenance hier. you can design what your want, if the owner don't do his job, it will break sooner or later.
Big task, thing is they put it in the shed last year and left it ! All winter to get it fixed!
Nice Job
yup.. I was just thinking that - "a stitch in time saves nine" you reap what you sow.. oh!.. but no reaping for this combine.
In fairness it had been repaired ,just not well enough. My guess is that machine had limped along for several seasons but they came to the point a proper job was needed.
@@johnsimpson8652 I do loads of repairs to farm kit, and it is neglect, and "farmers welding" which is the problem also putting off the cost.
1 farm worker has just fried a New Holland combine as he put 24 volt on a 12 volt combine fried all the wiring brain as the battery was flat...
Very few people like Oliver around, hope he gave them a decent high bill for saving the header.
I think it’s only their second season of owning the combine so it’s putting right what the previous owner/s have done
@@snowballengineering And you have made a top job Oliver,
These CATS will break any bit of kit.

Clearly you are the fourth Emergency Service in your area and expected to revive the dead. Well done.
You put in thicker material, appropriate (longer) bracing to the right spots, even in places the factory did not have it, and through it all got rid of the flexing caused by an oscillating arm connected to a large mass, all of that fatiguing the (flimsy) structure. You can think, work around issues and create a repair that will stand the test of time. Well done. Most repair shops would run a mile to get away from this sort of work. Only problem is that others will see your work and come from miles around to get your help. You will never be out of work. You don't need to charge the earth but make sure you get what the job is really worth. In many cases what you do saves the owner buying brand new equipment, which may/may not have the lifespan of what you have repaired/created. Retired mechanic/machinist/welder/fabricator in Land Down Under.
Nice one - that was a properly knackered drive. As an old farmer who fancies himself a welder (but who is NOT), I can attest to the evil that men do when trying to get one more season out of our equipment. There comes a day when it finally has to be done right 🙌
"We've buggered about with this for years but now it's literally falling to bits we want you to sort it out and provide a warranty. And we want a good price too!"
The end result looks amazing and it will outlast the rest of the machine. I hope you charged at least 20% extra for the nuisance factor.
I admire your tenacity. Had the client taken the mower harvester to the average chop shop, only the obvious would have been "repaired", just to fail in quick time afterwards. You remind me of one of my favourite sayings: don't fix the symptom, fix the cause. Another most enjoyable video.
Its perfect. It 10 times better than the New Holland engineers could come up with. Making it out of paper.
Once a chain is stretched like that, it starts wearing the sprocket. We saw a lot of this on motorbikes when I worked in the bike shop decades ago. It's a case of replacing the chain before it gets that bad, in order to save the sprocket. We even saw one case where the owner had replaced the worn sprocket and wondered why the new sprocket was wrecked in no time. He hadn't replaced the chain, so a new chain and another new sprocket and he was on his way.
The impossible you can do at once, miracles take a little longer. Can't think why you weren't happy with the result, in most peoples books you've made an awesome job out of a real mess.
The fact you pieced that back together when it was such a mess is a real work of art as well as an application of your skills and equipment! Hearing you say your not completely happy with it at the end was hard to hear but a mark of someone always driving for better.
I’m sure it was a train wreck when the farmer put in the barn following last year's harvest. If you cannot afford to fix your equipment, you should get out
@@joevalencic5275he’s paid to get it fixed hasn’t he? 🤷🏻♂️
That cracking is usually caused by running a blunt Knife and or the ball joint being sloppy. The Knife drive will bang from side to side rather than a smother action causing all that side frame to vibrate more under strain. A bad or worn track for the Knife slide or a bent header don’t help either. The hole header looks like it had the run it till it breaks service plan. Impressed with your repair, I’ve seen some bad ones and the drive box fall right off.
What a brilliant job you have done to re-engineer that broken mess of a gearbox mount. Well done.
Ollie, you are probably not half well enough paid for what you do!! From the Grimme harvester, the slurry tanker and now this header......the farmers in your area are so lucky to have a man like yourself around.
Keep the videos coming 👍
One of THOSE jobs. The customer should be pleased with the result. Excellent work, thanks for posting.
That was a tough repair. Nice work!
What a total nightmare Ollie. You remanufactured that entire design. Absolutely awesome job Ollie.👍👍👍
You shouldn’t complain about your welding as most of us are couch potatoes that don’t do any welding or very little. You weld better than most. I appreciate your work ethic and always try and make the repairs better than new.
A lot of what gets shown/seen on the internet is only people’s best but it reality that’s not always the case.
Mr Oliver, there is nothing wrong with the welds and even if bits aren’t pretty no one is ever going to see those welds apart from the farm workers, even they wont notice when it gets the guard on. However, they will like the pucka job you, (and the farmer) did on it, sparing no time or expense to repair it and beef it up.
I expect it will run like a sewing machine now. Look forward to seeing what trials and tribulations you will endure with fortitude and patience next Sunday.
Man you should make templates of that whole assembly left and right. I bet you that there is more than that one out there needing repairs. Great wow so much patience and attention to detail. Great video. Thanks for sharing.
Fantastyic, what bloody trooper you are - I bleeding felt that spring to the back of the head - believe or not I was thinking how painful it woulds be before its happened - the farming community around you are so bloody lucky to have a committed and talented young bloke like you around - smashing.
Ollie, that was the best work I've seen you perform for a long time. Not saying that other projects were less good, just that this "Wobble Box", as we used to call it, is one of the most prone to failure, due to the stress the knife puts on the gearbox, and the speed it changes direction. I''ve only done it once, and never again, in the late 80's on an old MF 525. Took forever because you were chasing cracks everywhere. All had to be sorted otherwise 1st time it ran, it would pull the gearbox off again. Simply put, with this job : You're the master!!!!!!!! So glad you used 10mm on the actual g/box mount, as that is where all the twisting and sudden changes in dir happen. Nothing I wouldn't have done, other than, in my day. it was gas/axe and welded and arc. Didn't have plasma or mig. Once again you have blown the opposition out of the water with your engineering skill. Absolutely top class work lad, from an old Ag eng.
This has been a known issue for years, we had a 40ft one for 2 seasons and it was such a disaster NH Australia investigated it and the end result was because the knife is mechanical drive but it's split in 2 and waxh half of separately driven from each end, due to machining tolerances one drive pully on one end might be a tiny amount smaller than the other, so they drive at slightly different speeds, so in theory you set the knife's so they work against each other, they push push in together and pull together to cancel each other's vibration,
Due to the different pulley sizes they can get out of time and sync up so one pulls and the other pushes, so the whole knife is working as one, this sends huge vibrations though the whole machine and used to vibrate the windows so bad you could see the glass shacking
The fix was to machine one pulley 3mm smaller, so they're never in time but they can never sync up with each other either,
A normal header like a honeybee or mcdon is hydraulic drive and due to the nature of hydraulics they're always speeding up and slowing down and they can never sync with one another,
One of those jobs that snowballs, so they got the right bloke. Welding dissimilar metals always makes life harder, especially when one is only 2mm. Another case of agricultural kit built down to a price. Made the best of a bad job and gets them going again while Yorkshire has it's brief window of good weather.
Very enjoyable viewing. Thought process and warts and all solutions. Having the confidence to dive in and problem solve on the fly makes for a good tradesman.
Great video and thought process, with the added touch of a job very well done. 👍
Ollie , you managed to make a silk purse out of a sows ear, again. 👍.I don't know how the manufacturers get away with making such expensive machinery out of such flimsy metal. I think you found the main cause of the vibration with the misalignment of the gearbox drive to the knife blade. The vibration must have been intense because of this and combined with the very thin material the cracks were so plentiful. Your repair will no doubt be a much longer lasting life for this piece of machinery. The owner should be very grateful for your skills.
A mechanic/fabricator friend of mine worked for years on offshore oil rigs and showed me some pix of the nightmares he dealt with, more or less along the lines of the "New Holland" but he called them a "dogs dinner". Great stuff as usual I do hope your customer appreciates what you have done here!!!!!
Your customers are lucky to know you, that’s all I can add. Very impressive work. As an everyday DIY hobbyist, your work is so inspiring Oliver. Thank you so much for making such an amazing effort to film as much as you do.👍👏👌🇦🇺
This should be compulsory viewing for every single NH engineer without exception. The bill for this would have to be substantial, but your local farmers are extraordinarily fortunate being able to bring this sort of shambles to you and get a result.Well done.
I love your confidence in your own skills and ability. Rather than do half a job, just keep cutting out the old knackered bits knowing you can put it right.
good job, well done, hope the customer appriciates you re-engineering his machine, instead of just welding the cracks.
Wow that was a lot of digging before reassembly. Good work.
And ouch I flinched when I saw that.
If it can be fixed, you're the right man at the right time to get the job done right.
This seems to me like a manufactures defect.
Jest to jedna z najciekawszych napraw jaką widziałem pośród Twoich prac. Ciągłe spawanie nowych pęknięć przez użytkownika pogarszało sztywność podstawy przekładni co spowodowało jej zniszczenie. Naprawa wymagała wycięcia praktycznie całej podstawy i dorobienia nowej o grubszych przekrojach blachy co gwarantuje bardziej sztywną i wytrzymałą konstrukcję . Spokój i fachowość były z Tobą przez cały czas , robota wykonana super i gwarantuje niezawodną pracę przekładni na długie lata . Pozdrawiam M.K.😀
You make the greatest work out of the crappiest situations I give you that!
On a side note - it just goes to show you that welding is not an easy job and needs to be done correctly in order to work properly. Any average Joe can't weld this up in a hurry and expect it to last ...
This was a challenging repair, most would turn it down, good job Oliver
A great bit of engineering. Farmers don't care uf it looks beautiful, they just want it to work and keep working. Si fantastic job all round
Having grown up on our family’s dairy farm here in the states using multiple pieces of New Holland equipment and repairing it pretty much all of my life (I’ll be 60 in a few days), I can tell you what you already know; New Holland is notorious for under-building their equipment.
Ohhh, jeez, I felt that. Another lovely job Ollie. In my experience, when you beef up plant that has cracked like that, the cracks move to another position. But if they get another 5 years out of it, it'll be time for a new one anyway.
Most people today would have just bought a new header. But your repair job should last another 10 years. I'm sure they have other issues with the combine also. But at least the header should be fine for the next season. Great job, Oliver, and that was definitely a jigsaw puzzle. And you definitely made it much better than factory again.
Very impressive thought process, explaination and execution. A treat to watch.
Another excellent installment Olly, appreciated your Dad giving it a bit of a tickle there toward the end ;)
Hats off for talking a job like that. Nice work that will outlive the machine.
That was one hell of a job Oliver, you have the patience of a saint and quite some skill..
Hi, Oliver. Nice job saving that header for another season or two. That thing looked like 1,000 welds moving in loose formation when they brought it in. And it's no wonder when New Holland mounted that gearbox on 2 mil sheet metal. And it sure looked like there should have been a 100-pound cleanup fee added to the bill. With all the dirt and grease/oil on the chains and sprockets, they're just leaving grinding compound in there to wear down the sprocket teeth and chains. Thanks for letting us look over your shoulder and see you next week. Cheers.
Nice one Oliver, but remember its not a good idea to try and straiten things with your head!
At 80 years old I love your channel and look forward to your next thanks foe sharing all the best regards Ken
Wow, I can't believe you managed to rectify that utter mess. Brilliant job, Olly
Oliver, you re-engineered the whole gear assembly, just amazing…..
Lovely fabrication, takes me back to my farming days. My dad was never happier than having a sledge hammer, oxy acetylene torch and his welder against the clock during harvest. 👍
Excellent job, Oliver. First class fortifying the paper thin garbage of the original. TOP.
You’re a real craftsman Oliver. I love watching how you get round problems and finish up with a “proper job”. Loving the summer haircut as well.
I am very impressed how you managed to solve this messy jigsaw puzzle here. Bravo! and thank you very much for sharing!
Yes, simple stuff, but a proper nightmare! Well done Mr Snowball! Thanks.
I love the way you over think this problem. You want to make it last and keep the farmer working. That the way it shoud be!!!! Most people would have done what we seen and moved own, I belive that this is the way to sshow your pridein your work. This is way I keep watching you. Thanks Donald..
If I were your customer, I would be VERY pleased. Very difficult and very honest work. My congratulations and best wishes for success!
37.20
if you have large holes or cracks. I always put a flat copper strip behind it, you can just weld it full and remove the strip later. grind out and, if necessary, weld over it. but you made it great again
Congratulations to the engineers who designed this. Most likely they never foresaw that if the joint had more air it would cause higher VIBRATIONS.
This reconstruction job was done well considering what there was to start. Great work Oliver.
You're a better man than I am..I would have had the customer at least help with the disassembly or at least clean the debris out first. Well done sir, we need more folks like you around
Another sunday morning who start very well, thank you for sharing, i learn a lot, 👍👍👍👍
Another great job Ollie, these customers really need to appreciate the fantastic work you do and the dedication to providing them with a quality product
You summed it up early in the video " Where do you start and where do you stop " , I dont even think a Doctor has seen that many fractures . It fought you all the way even had a go at your head , but you got there well done .
Well done Oliver, what a b.....r of a job. I much admire your tenacity and skills.
Mate, that was bl00dy good. I was glued to the screen watching you design and build a better, stronger machine. Good education and great entertainment. Looking forward to the next one for sure.
I laughed when you had that entire piece just fall out when you were using the plasma! One of those jobs that just gets worse the more you get into it. Love the methodical approach and making the repair better than it was new.
I always find jobs like this…..frustratingly satisfying, you seem to put a lot more time into them than is practical but if you don’t get to the root cause then you may as well not do it at all, so it’s frustrating, but then when it all comes together, you know it’s right and done decently, then it becomes satisfying. I’d bring my farm machinery to you any day as you always do the right and proper repair, it’s a credit to you, well done
This one was like opening Pandora’s box. Remove one section at a time to find more damage under each section removed. Great repair! Thank you for sharing your craftsmanship with us.
What ever you charged, it wasn't enough. That was fabulous, and you saved the farmer from buying a new header. $$$$$
A good example of a faff - excellent work. It is also very interesting to see how all these farm implements work - I had no idea!
I reckon this is time to buy a new one. Well done for persevering and sorting the job out.
New ones are very expensive and I don’t think you’d be able to buy a new one for that age of machine now.
Fantastic job. You are one hell of a craftsman. The folks who serve are very lucky to have you. Thanks for the video
I really thought you bit off more than you could chew on this job but you pulled it off. I'm always amazed at how you puzzle it out. You have me using that term when I'm trying to figure out how something works. Great job.
Another incredible job, the farm machinery you repair always seems to have had a chequered repair history and once again you have removed all the bodges and made it stronger than it was originally. Thanks for the video :)
I take my hat off to you Oliver. I thought last week’s video using the mill as an improvised lathe was stressful but it wasn’t a patch on this week’s.
I hope the customer has been billed an appropriate amount for your exceptional services.
Today’s ‘Snowball’ was watched to the accompaniment of roast chicken and all the trimmings and a glass of Aussie wine, apple pie and ice cream. Sleep imminent 😂.
Thanks for this really absorbing video Oliver.
Best regards
Mike (the Anchorlube man).
that job would have had a big "NOPE" from me! excellent repair Ollie.
40 more years! EXCELENT JOB, Greetings from Panama.
Definitely not a job for the faint of heart. Great job sir, thanks for taking us along!
I think "impossible" would have been an understatement. Ollie you are a dead set God of Welding.
Much credit for sticking to it. That really is a lot of work, both physical and mental.
Oliver, once again you have produced a repair that is far superior to the original product. More robust, certainly; Yes, it may not be as pretty, but it is going to last longer, flex less, and wear better.
Well done Ollie . Above and beyond, as before . A job many would have run away from 🤦♂️🤔
For sure . Shows your excellence . As a fabricator .
And theirs you worried about what the welds looked like . Well done again 👍
Oliver “the magician” snowball, fair play you earned your corn there
I feel your pain! having similar problems with our rail mounted Coles Crane. The more you remove the more you find.
That was like trying to knit sawdust, and a lot of other engineers would have thrown in the towel, however not you Oliver, it’s not over ‘till it’s fixed - and that’s, perhaps, why your customers value you so highly - good work!
great to see another job come together again
Good job. Many people would have said no thanks to complicated. It’s often the case that it’s doable but ripping it back to the bare bones is outside their comfort zone. Another great video.
I admire your patience. I would have never accepted a fiddly job like that.
Oliver, once again you've smashed it.Excellent problem solving skills. Cheers.
Morning (at least here) Oliver: OMG! Take about FUBAR!
You thought and fought your way threw another repair! Results look good and look strong. Well done. Until next Sunday morning. Be well
What a fantastic job! That’s one lucky farmer to have such a conscientious and skilled engineer to fix a bad design and old bodges. Welds look good from where I’m sittting!
I enjoyed that video. Thank you.
I think we all probably went "OUCH" and metaphorically felt that bang on the head on your behalf!
And whilst I was watching, two CLAAS 8800 LEXION combines [2022 and 2024] have been harvesting the wheat [12% moisture content] surrounding my house!
As per usual, you turn a sows ear into a silk purse. Great work as per usual. 👏👏🇦🇺
Well, you made something that was only to be scrapped, very usable for the future. The alternative would have been Manners combine graveyard and hopefully get a replacement header. When you walked back to the workshop you looked very mucky and tired out, but you should be really pleased with yourself for the end result. Well done you. A T B Clifford.
This dude has skills. Careful bumping that noggin!
Sometimes simple things are the hardest to figure out and fix but you always make it happen
I’m sure you’re glad to see that one go down the driveway. Great job, a challenging mess you had to deal with. Thanks for sharing it.
Oliver, your videos are like watching a murder mystery, you never know what's coming next and how it all ends. What a brilliant video. Don't knock yourself too much on how it looks. It works better than it did before and that's what's matters
Outstanding problem solving and fabrication. Great work Oliver! 😎👍
Another great video. It's 1:30 am. but I had to watch this great repair job. I am fasinated by your work.
I send greetings from West Texas
