mid 80's MF 2625 - MFWD - front axle not working

Anonymous-0 · Nov 5, 2012

I am gonna have a look at an absolute auction where there is a MF 2625 for sale. Front Axle listed as not working. Though I am going to assume the tractor runs and drives other than that. I don't care about it being perfect, just need 100 HP. Does running a tractor with a non engaging front wheel axle pose any concern? I mean, I don't know which part of it is broken, the drive shaft, or the axle differential itself. Basically it is reduced to operating as a two wheel drive. Which works for me. Any thoughts on if this is an acceptable approach?

Not familiar with this model. Parts book shows it was made in India for US and Canada market. Looks like the drive for front axle is attached to the side of the trans, with most everything involving the shifting/engaging componants outside the trans. That's a good thing, since it seems likely that only one gear would be a real chore to access, and that's probably not the failure anyway. You can operate in two wheel drive. Once you determine what and where the failure is, you can decide what to do next. If the problem is in the side box/shift mechanism, you can either leave it disengaged, or remove the damaged parts and reinstall the side box with those parts missing. If the problem is in the front axle, you can remove the covers from the front outer planetaries, remove the sun gears from the stub axle shafts, and reinstall the covers. The wheels will still turn, but the gears and shafts within the front axle housing will not.

Hi, I'd agree with Harry. The essential thing is to determine where the problem is first. Start off by disconnecting the drive shaft at the rear end. Make sure that you have the 4WD engaged, Support the driveshaft and move the tractor. If the drive flange turns you will have drive to the shaft. If it does not the problem is in the middle region of the tractor. Try it again with the 4WD disconnected. If the flange does not turn all appears to be OK in the middle region of the tractor. Make sure that there is no movement from oil drag.

Turn the driveshaft by hand. If you can turn it the problem is at the front end. Jack each side up seperately and spin the wheel. Listen for any strange noises. I'm guessing that it would be a crownwheel and pinion problem. It is essential that you inspect it and make sure that nothing is broken/can break and possibly punch a hole in the casing if it gets caught up.

Very informative response, thank you sir. I like the observation that most of the shifting component is an external box, not inside the housing.

Thank you sir for the detailed trouble shooting reply. That indeed sounds like a winning approach to isolating where the problem is occuring.
