Countershaft seal replacement problem - collar stuck
I'm attempting to fix a countershaft seal leak for my Gen 1 KLR650 (2006). Upon pulling the countershaft sprocket it was clear the seal was half out of the case -- hence the major oil leak. I purchased the seal and the o-ring that is behind the collar for the repair.
I can't figure out how to remove the collar. Everything I've read indicates it should easily slide off of the countershaft. While I could just clean the surface and install the new seal (without pulling the collar and replacing the o-ring), I'd rather pull it and inspect it to avoid having to get in there again. I'm not really sure what the collar does and whether it's being stuck contributed to the problem.
Anyone have a solution? I'm thinking a dental pick to get behind it and pull it out. OTOH -- I don't want to create a problem. There is some rust on the collar face (not the sealing surface). I think the collar to shaft doesn't need to move and forcing it out might damage that surface. Leave it alone or remove it?
