Repairing very worn cast iron tractor axle. Valtra T203

- In this video I repair a worn out axle centre pivot.
The first job is to identify what the axle is made of, this is done by breaking a piece off and inspecting the crystal structure, a grind test to see the colour of the sparks and also by filing a little bit off and checking the filings. The decision was of cast iron.
The weld area was ground down ready to be welded. Super cast ultima rods were chosen as a filler material. The whole area was preheated and then the worn area was built back up again, the burner was left inside the casting as a post heat to cool the axle down slowly.
The axle was then moved over onto the milling machine where the boring head was used to turn the pivot down to 110mm. The top surface was also faced off.
A steel shelve was made in the lathe to be fitted over the pivot to bring the final size back up to the standard 120mm. The shelve was expended with heat and then shrunk on with 0.25mm interference fit. A small chamfer was put onto the new shelve to finish the job off.
Hope you enjoyed the video.
Thanks for watching. - Наука та технологія
Must've been a big snake wrapped around that farmer's grease gun!!
Your assuming he had one!
Guessing its a livestock tractor 😂. Strange that the other side was ok, wouldn’t be the first person to not realise that there was a bearing on the rear pivot as well as the front.
The rear pivot is usually lubricated by leaking engine oil so it doesnt wear as much 🤣
😂 highlight of my day these comments
The funny look after “farmers are usually good at greasing their machinery” is priceless.
Really 😂😂😂 what do think Agricultural Engineers Do Play Tiddle winks or some thing 😂😂😂
No music no blabla no bulshit just proffssional interesting content, and learning that you can't see everyday.
Good work, i'm watching you from Québec Canada 😉
Only thing I would have done that you didn't would have been a machinist jack on the table at the knuckle end to support and reduce stress on the angle plate. Since nearly every thing I do is out of my comfort zone, I appreciate watching others go there too. It's how we learn to do the cool stuff. Now, if only the operator can find his grease gun.
Always amazes me how people can let stuff get so bad before they think it might be time to fix it.
Said it before, but this channel has now become the UK equivalent of CEE. Excellent work again, lets hope they actually grease it this time.
shoutout to CEE. Unfortunately his last cast repair job didn't turn out well. But happens to the best of repairmen.
@@jazko Yes that was a bit of a shocker, hearing it pinging the way it did.
Was that a dig at Farmers maintenance, obviously had FEL on tractor to get that bad as well. What was the other side wheel like?
@@fredscheerle7592 Apologies, but FEL went straight over my head.

Love your honesty when you are doing something that you have not done before ! Also I like the way you think on your feet and come up with solutions to problems ! Keep it up young man you are doing great work and it is refreshing to see !
This channel is THE definition of ingenuity at it´s very, very best!
Fabulous repair, so many elements to work on, and adaptions of the milling machine, super job Oliver.
Very smart machinest
I don't remember a farmer greasing anything before those 18v grease guns came along!
Sunday morning magic
A very minor point compared to the excellence of the repair but I hope it is helpful. The laser indictor on infrared thermometers makes it look/feel like you are getting the temperature at that exact point at any range. In reality the infrared cone widens quickly - if you would like to truly know the exact temperature of a particular spot you need to test from only a few inches away. (Many IR thermometers do have a graph indicating this on the side, others it is hidden in the instructions.)
More content much appreciated by an engineer/machinist who occasionally does a bit of welding and often learns things from watching you. Thank you.
That is helpful, thanks
Snowball - Superb engineering on a Yorkshire budget. To do that with cast iron - well done.
When the farmer comes to pick it up - show him what that grease nipple is for - he will be truly amazed!
So interesting to watch Oliver, he's in-between a blacksmith and a fantastic engineer, can't fault him. The tractor must be off of a dairy farm, they don't know what a grease gun is, my cousin his a prime example.
Snowball engineering is always trying to improve his ability to take on certain jobs which normally wouldn’t entertain, Such the cast welding and the machining with mill to finish up with a nearly perfect finish, Extremely well done for taking on and showing these great engineering videos 🇮🇪
A Snowball Engineering video on a Sunday - lovely!
Those cast rods worked really well! Much better than those I used to use, usually unsuccessfully, 50 years ago! Nice job of machining too! That pillar extension worked a treat too! 👌
Tech has advanced quite a bit from back then. A week ago i fixed my brother's stainless steel water tank in the middle of the field with a stick welder. And they worked perfectly with a cheap little inverter i bought just for this job. :))
@@aserta That milling machine is awesome. What is it. I have a burke number 4 but I really need a Bridgeport. That thing can seriously handle larger equipment with ease.
NiROd is STILL junk today. - Great for camouflage but no good for actual work. ----- 1- Gas weld with real cast iron 2-Tig braze with Si Bronze. 3- Braze 4- if you can't fix it with one of those, Screw it.
The temperature reading you get with your IR thermometer will vary enormously depending on whether you're pointing it at a fresh shiny surface or a dull dirty one. A clean shiny surface acts as a mirror (a hot mirror) that causes the thermometer to 'see' some other part of your workshop, which is colder than the workpiece itself. Playing around with a thermal imaging camera is a good way of getting a feel for this.
Yep. That's why i stick to temp sticks when it comes to measuring temps. They're accurate within their spec and can't be fooled by any imperfection.
@@asertatemple stick do a electronic version now instead of crayons, essentially you touch the surface and gives readout (think it’s up to 600 degrees C)
However like you the crayons are pretty fool proof and easier to keep in your top pocket 👍
Another nice fix .
And the viewing angle of the infra thermometer should also be taken into account.
I first thought of him using temp stick. That is what I used back in the 90's when welding on petroleum platforms. I know it sounds old school but it's fail proof.
Love the way you overcome tooling problems by quickly designing and creating new tools.. a very versatile approach 👏
An excellent repair. That must have really been clattering before.
Very nice rebuild of that huge metal cast iron tractor axle part. It should work for years to come now! Thumbs Up!
Thanks 👍
Nicely done. I've never done it myself, but many of those doing welding to cast iron use a thermal blanket wrap the workpiece in order to extend the cooling period as long as possible to reduce post welding fractures. Was good to see the mill column extension put to use... Enjoying your videos :)
Unfortunately I don’t have a thermal blanket.
When I did my city and guild's we put the cast jobs in the coals in the forge and let them cool together!🤣
I enjoyed watching this very much. It looked like one of those jobs that could easily have ended badly. Fabulous result. Hope the customer was suitably impressed 👍
A very good save indeed. Cast material can be notoriously difficult if a job is rushed. Care and prep work is the key and it is very satisfying when you get the result you wanted. Thanks for posting an excellent video.
Thats a nice fit Ollie. Cast can be a bitch to weld. I did piss myself laughing at your anxiety when the heated part was cooling on to the boss and you were rushing for the hammer. That is a repair to be well chuffed with. Keep them coming.

That is pita to grease. You have to get front axle up in the air and swing it when greasing. Or that is what valtra says. And points are under tractor of course.
Yeah it should have a remote grease piont. If it's too hard to get to it's not going to get done most of the time.
My pop, an english man, was what you would call, a natural engineer. You remind me of him in so many ways.. You have a gift. I am very impressed by your can do attitude.
Well done, Olly. Top work!
Great job Oliver!
A joy to watch as always Oli, your thought process is second to none. Nice to see the Walhaupter head at work. Keep the content coming. Paul
Many thanks!
Another good job as usual. Always good to watch.
Excellent repair job!
What a fabulous job you did there thanks.
A glory to watch.well done
Great repair Oliver, nice winter job.
Thanks for sharing.
Nice job here in the u.s. that would have been scrapped know one would've even tried to fix it excellent work.
Good job done ! Really enjoy your nice easy jobs !
Nice job. Always have a hammer handy when doing a shrink fit.
Interesting to watch your work. Thank you for sharing.
Nicely Done Oliver 👍🏻
Great job ! Thanks for the videos Snowball.
Enjoying watching the channel grow, and the videos too. Nothing too slick and some nice workarounds.
I really like your "warts an all" approach makes your vids "human" and very watchable!!!! Damn good job overall.
Nicely done Pal
You have done a cracking job there, well done bud
More great content there... Thank you for sharing your work.
Nicely done as usual 👍
Awesome video, great work. Thank you Oliver
you've done a brilliant job there and saved the farmer a fortune I dare say
Well done Oliver a good job👍👏👏👏👏☺️
I knew you'd get it done well.
Besides your being very smart, you must have had a good teacher
I love the problem-solving. Great filming, slow motion was enjoyable. Thanks
Great job, as always, mate.
I'm impressed. Kurtis at Cutting Edge tried to do cast iron welding (albeit it was a differential case and thinner) and the cracks kept forming when it cooled down.
Fairly sure that casting was poorly cast, alot of internal stress.
@@bostedtap8399I agree. Regardless cast iron is always tough weld.
Excellent thought process + great plan and execution = fantastic result!
Another excellent repair there.
Another real world repair that worked out great. Very few things are harder than cast steel that gets welded.
Well done keep up the good work young man
Love how precise u work
Great job as always👍🇬🇧
That was a real good fix---customer will be happy
Fair play Ollie, savage repair job there. One of your toughest yet and ya never let it phase ya. Top job
Well done, mate! I never cease to be amazed at how your repairs turn out. You got skills and patience and that will take you a long ways!
Dang you did a great job! Especially for it being cast iron! Keep the videos coming!
Fantastic repair
Top job as always 👍
Ottima riparazione sempre bravo👍
Gday, certainly greased regularly, possibly every 2nd Christmas, great job, cheers
Great repair, well done
Thank you for videoing your work, very interesting.
Great explorations; appears excellent results! " Nothing venture, nothing gained" ! Thanks for the look. Enjoyed and learned some things.
Great job. Not an easy medium to work with cast iron. Reinforcing with the steel sleeve should give that axle a new lease of life. The only way people can keep running these machines is with the help of skilled engineers to repair and fabricate parts. The old Boys are all retiring or dying. Good to see someone younger taking up the mantle.
This job sure come's with its own set of challenges ..Nice work my friend !!!!
But what did you have for tea? Well done for sorting out the top face, I was shouting at the screen!!!
Thank you for sharing, another great project 👍👍👍👍
By far my best UA-cam subscription!! Really enjoy the variation in work and your pride in your work 👍 thanks
cast repair i stayed away from this as much as one could but back then we never had the choose of rods and wire like now but you mastered it put a lot of weld in there and the end result speaks volumes of your talent for sure now you just have to get the farmers educated as to a substance called grease and oils or maybe not as it sure is a steady source of work income for you love your bit of wit at beginning of video Cheers Mate
Like to see someone learning as there going and actually showing people, bloody good show that man 🧐👍
Definitely a machinist fit. Great job and great video. Thanks
Excellent job man, great video, keep'um coming..
Ingenuity at work. A job well thought out and completed. Very well done. 👍
Quality workmanship Excellent job.
Nice work mate 👍
Well done as always lad !
Nice job! Real silk purse from a sow's ear number; you have my respect.
Great repair, good work.
@ 5:27 Those sparks, definitely cast iron. 😊
You are so good at what you can turn around top man
good job !
cheers ben.
Really fascinating 👏, brought that axle back from the dead 👍
Good job brother! Came out clean in the end and that's what matters
fantastic work! great video.
Nice work!
Another great video. Good to see people going outside their comfort zone and persevering until success
Hello Oliver from the USA. Just watched your video. Yep, cast iron can be rather tricky to repair. Good job!
As long as the operator greases the fitting, it will last a very long time. Well done. Nice repair
Great job and another bit of kit saved. Thanks for posting.
Thanks for watching!
I enjoy watching your videos as it takes me back to when i was an apprentice back then we did not have CNC machines please keep the video coming .
Very nicely done!
Recycling at its best, well done mate, excellent job,
