Countershaft

[Deaner]

Has anyone knicked the rubber bearing case while replacing the countershaft seal. Just did mine and the rubber case that holds the bearings together has some small knicks in it. Could of been from me or the previous owner. Just wondering if this will affect anything. It’s not wrecked enough the rubber is going to rip apart(or so I hope) so I think it should be fine??? What’s are your thoughts?

I would monitor that one for leaks and buy a replacement part and keep it on hand just incase.

I put a new seal kit in. Seal, bushing, o ring, washer and bolt. The rubber I’m talking about has nothing to do with the seal but I’m just worried about the integrity of it now as it holds the bearings.

That could go either way, the positive is that bearing runs in oil. Change your oil into a strainer/cheese cloth and check for the plastic in the bearing. After every ride grab the front sprocket and move the shaft up and down, once you start getting a little play install a new bearing.

Sounds like you are talking about what is called a dust seal that sits between the inner and outer race of the bearing. It can be removed if it’s a concern.

I had assumed he was talking about the plastic cage the roller bearing run in.

Maybe my bad , last counter shaft bearing i replaced was a garden variety ball bearing. Read the op again and sounds like some fancy speciality caged bearing design. I am out
