so I have an end play spacer that I am slightly concerned about. It has a small groove worn into it from the bearing plate due to a worn stationary gear bearing allowing the e-shaft to move enough that it started wearing. I have a new bearing plate but was wondering about the spacer.

I assume the spacer's primary job is to prevent excess axial play of the motor but didn't know if it also played a role with the front needle bearings. I have already slightly..slightly sanded down the outer most 'high spots' where the metal pushed out.

It seems that this sits inside the needle bearings and if there is that very small low spot would it affect the needle bearings at all. Does this spacer spin inside the needle bearings at all?

ANY insight would be helpful. I don't mind getting a new one, just wondering if anyone has reused one that had a similar wear....and the wear is very minimal and may seem like a lot more in the pictures which is why I took a few from different angles.

Thanks

 

I don't really like the looks of that. Ideally you should have a few different thickness new ones on hand in case the end play is out of spec..... More common than you might think.

New spacers are around $20, I'd go that route.

 

No good. Looks like that engine had some heavy stationary gear wear allowing the spacer to make contact with the bearing plate.

 

That most likely was cause by the thrust bearing assemble being loose during assembly. The thrust bearing got squashed do to drifting off center. Thus as the spacer rotated with the
e-shaft it rubbed against the now stationary non rotating bearing.
