Allis Chalmers 5020 4WD front end rebuild
I bought a nice looking Allis Chalmers 5020 4WD in mid-August with less than 600 hours, and installed a loader. The first day I worked it, I saw the left front wheel catch a few times. I stopped work, took it home, and took it apart. A bearing had disintegrated. The fragments from the hard steel inner race chewed up the spur gears and the housing in a hurry. I thought that it would be useful to document the repair here. It's fairly simple. The most difficult problem is finding parts! The phot here shows the large spur gear that is attached to the stub axle.

Hi Tesch63 and

I picked up our tractor for my parents and found the right front drive is destroyed. Wanted to know the best places to look for parts. Allison 5020

never mind.
I am having the same problem with my 5020. My bearing disintegrated and chewed up both gears. I was able to find the smaller gear and tried to have a machinist rebuild my big gear. Yeah, no.
I need a new gear. I am having horrible luck to say the least. I live on a farm and am kicking myself. It was all of 40 seconds and all **** broke loose.
I already cleaned everything out and have it all together and using it without 4wd but it is mud season and I need my gear.

how did you get the old bearing out?
...the post you are quoting is from 9 years ago, and MitchK hasn't logged into the site since 2016. You are unlikely to get a response from that user.
I cajt figure out how to get the blind hole bearing out of the housing
Can you post a pic of it?
Depending on the type of bearing and what's around, there are a variety of pullers you might use, if it's just an outer race for a cone bearing, just welding a bead on the inside can be enough to get it out (as the heat shrinks it a little, so you can quickly pry it out).
