Axle bearing replacment

Dumb David · Mar 13, 2020

Problem ! I pulled the axle of my TE20, replaced the bearong and seal, and when I tried the new retainer collar on the shaft it slid easily down right on to the bearing. Every axle I have ever worked on like this before the collar was undersize and ad to be heated to go on te axle. The axle mics exactly two inches, and the collar is listed at two inches. Is this situation different from say. Nissan truck axles? Will the collar shrink to a tight fit after being heated red hot? Help, its almost spring moing time!

Lochtite makes a bearing retainer fluid, works great. You could also use a centerpunch to dimple the shaft to raise points on the shaft to keep the collar from turning.

Something is wrong, were did you source the bearing and collar, and where did you see the "spec" for the colar the same size as the axle.

I don't know about your 20 but I did that job on a 2000 and that collar was .002 under the axle diameter and the axle was ground on a slight taper, smaller toward the bearing. Took a LOT of torch. How did the old collar come off?

Ted, for gosh sakes, it's not a matter of "the collar turning", it's a matter of the axle separating from the tractor, which could be disastrous if operating on a slope at the time, or driving in high gear!

Sounds like the collar is made wrong or paired with the wrong bearing assembly.

It should be a press fit. I've never heated one to get it on, just pressed it down against the bearing. And no, heating it will not shrink it down to fit.

I would contact the seller, try to get another bearing, preferably a different brand. See if the collar will fit. You can leave the bearing that is already on the axle, just put the bad collar and unused bearing in the original box for return.

I had a late '78's Buick that had a rear axle bearing failure and it boogered up the axle to the point where replacement bearings would not "interference fit"
and hold the axle in place and yes it would work it's way back out and I worried about it letting the axle come out. After several frustrating tries with new
bearings and seals, I spot welded the inner race to the axle in 4 places and that was the end of that.
