Unusual wear on throw-out bearing

Posted by Ken_P On 2020/10/27 14:44:44

I have the engine out of my 1938 120, and inspected the clutch and throw out bearing while I had the opportunity. Clutch looks fine; I suspect recently upgraded, but the throw out bearing is odd.

The bearing itself had a lot of play, and needs to be replaced (it is a modern sealed bearing), and the ears on the throw out bearing collar, where it sits in the clutch fork is worn. What could cause that sort of wear?

I did the obvious, and checked for straightness of the clutch fork, and fit on the ball where it pivots. All seemed fine. Anything else I should look at, or has anyone else seen this?

I'll post pictures of the wear later tonight when I have access to the pictures. Thanks!
