I had a similar issue with my 4540 I picked up for cheap. Gear oil poured right out the left hub. Had to rebuild the outer left hub and the pinion gear similar to yours. Bearings were chewed right up. Service manual on mine calls for heating the front taper bearing up to 120C to fit it on the pinion gear. That made putting the taper bearing on really easy! No press
Always nice to have a hydraulic press to press bearings in with. I've used my former boss's hydraulic press several times. His has a gauge that told you how much pressure you were exerting on the part in PSI, which was really handy. I remember rebuilding a retractable landing gear on a 1980 Piper Arrow airplane where I was basically pressing steel bearings into aluminum castings. There are four castings in an Arrow and I remember gritting my teeth while I was pressing those steel bearings in place and hoping I wouldn't crack any of those aluminum housings because each one of those housings was $1100.00 a piece! Fortunately, I got the new bearings installed in all four housings without a problem, got the landing gear all back together, the gear retracted and extended flawlessly the first time. Having that PSI gauge on the hydraulic press helped a lot. Lol!
@@radozeman When you are reassembling the axle, after you slide the differential and ring gear into the housing, what holds it in place? Does it just free float against the pinion gear? We have a Mahindra 7010 apart (due to a broken pinion gear) and it seems like an odd design as it appears that the diff/ring gear just float in the housing…? There’s a snap ring on the outer end that stops the diff, but not on the pinion side??
That is the wrong hole. The gear oil fill hole has a gauge that you use. it is actually a dipstick that is used to so that you dont run the differential dry which is what you did.
How many hours do you have on that tractor? What brand and type of hydraulic oil do you use ? I bought mine 2nd hand and didn’t get a manual with mine.
I'd like to say 500 hours, failure in was lack of oil, either we didn't fill it properly or it leaked out. We use the Mahindra brand hydraulic oil, and Mahindra 80w90 for the front axle.
No, we did not, my dad thought maybe he forgot to fill it when he changed it out last time. We have been checking it periodically and so far it has been fine.

Good to know! We did not have a service manual available.
what you are calling the fill level plug is the vent for the main hubs. if you fill it to that level the differential will not have enough gear oil.

I've seen that on some presses, always thought that looked useful, unfortunately i don't think there is a way to incorporate that on this one.

Great video -Safety Glasses a must !
Eh I prefer safety squints 😁
Nice video. Like the Milwaukee light.
Yes, that big Milwaukee light is great!
@@radozeman i work for milwaukee and i've been eyeballing those.

What was your parts cost and where did you order from please ?
I few hundred if I remember correctly. Our closest dealer at the time was Louis Gelder & Sons in Hart MI

what gear oil do you use?
We used what the manual recommends, I don’t recall what it was again without looking it up.
Have you found the leak ? What if it leaks out again that will be another 2000
No, we did not, my dad thought maybe he forgot to fill it when he changed it out last time. We have been checking it periodically and so far it has been fine.
This guy sounds like a used car salesman!
it may have had a bearing go out then the oil leaked out causing the lockup
But won't we see that? Spot on the floor or something?!
