1961 MF203 backhoe loader rear axle question

Jdimassi · Jul 7, 2019

I recently bought a non running 203 with a locked up right rear wheel assembly

Got it running good
Took the planetary assembly apart on right rear wheel it was destroyed broken chipped gears bearings gone etc etc ...

After i unbolted the planetary assembly i see the axle shaft has 1 chipped tooth

My question is how do i remove the axle shaft i saw something in the manual about locking the brakes for that side ? Do i slide hammer the shaft out?

I already got used assemblies off a mf65 tractor that are in great shape and look the same

Do you think missing one spline will mess up my new planetarts ?

Yes, put some pressure on that side brake. Does not need to be really hard, but that will hold the two brake discs up in place when removing/replacing that drive shaft. Drive shaft will pull straight out, might need a little pry bar help. If the brake is NOT on, the discs will drop down, keeping axle from going back in place.

Thank you for the quick response !! Hopefully it comes out easily for me i will report back by the end of the week

Could I also add to Dieseltech's response to drain off the rear end oil before pulling the axle. Your oil level may be high enough to allow oil onto the dry brake discs once the axle is removed.

Will not budge! Had shale bars prying on it small taps with hammer still wont move any ideas?

Most likely the brake discs are seized on the axle shaft. I had to drive the discs off of one axle with a 12lb sledge when I recently changed them. You might have to take the axle off at the diff housing.

I looked in the square plate on passenger side and saw the splines were rusted up real bad where it goes to the brake assembly you are correct id say they are seized! I think im over thinking it i am going to put it together and hoe it can survive with a small chipped spline

I'm sure it will. However, you now know that you've at least got very poor, but more likely, no braking on that side. Most likely similar on the other side. Loaders without brakes can offer some interesting moments, especially if the terrain is hilly. Best of luck with it and be careful. Those old machines can still get a lot of work done.
