Replacing pivot bushings MHF 50

wjytexas · Nov 28, 2014

I'm fixing to replace the pivot bushings on my
1957 MF 50. I have an IT manual but was wondering
if there are any surprises I might encounter.
Everything works now but is sloppy. Thanks

Those bushings have a relatively thin wall.

There is a good chance you will find they are worn through into the casting.

Some may consider that a surprise.

I replaced the one in my TO-35, 1957 model years ago. as I remember the old bearing was not hard to get out.

I always wondered why they could not put a grease fitting on that joint and if we kept it properly lubed we would not have to do this.

my new bearing makes a noise from time to time, I keep it lubed with spray graphite. But to get the lube to the mating parts you have to jack the tractor up taking pressure off the top of the pinion bolt.

I did one on a 35 for a neighbor, took me 5 hours work to get the old bushing out. Had too cut it out in little pieces after cutting the broken front axle out. Even once I had it down to two rings inside the casting I had to grind through one side of each ring to get it to finally break loose. I have heard that sometimes they slide right out, if so it would be a really easy job.

I did one on my 65. It should be the same as the 50. I had to build up the pin and grind it down as it was worn. I made a new bushing from a piece of exhaust pipe. I had to drill it for the grease fitting. Its not perfect but a whole lot tighter than it was. Not too hard of a job.

Here's the last one I did, bored it out in the mill, then made a bushing because the pin wore into the support about 1/8th inch.

thanks guys. I'm hoping I'm doing this before the bushings have worn through but if history is any guide I'll probably find a problem.

had to laugh at "not too hard to get out." Every thing I seem to do takes about 3 days, hot lubricating greases and hot lubricating words, and then somebody tells me "Why, they just slide right out!"

FB,
what I think I did, if my memory serves me right.

the bottom of the bearing was still good as it never gets used.

with the axle off I took a hacksaw and gently cut the bearing in half insuring I did not cut into the axle, that allow me to get the bushing out.
