Do you mean the drive shaft bearing or the sprocket in the chain case?

Drive shaft bearing

Okay, loosen the track as much as possible and then remove the skid.
Drain the chain case, remove the cover, and take off the chain.
Loosen the bearing keeper plate in the chain case and then remove the keeper plates from the other end. The bearing is locked to the shaft with a cam lock collar. Get that off and the bearing should just slide off.

There is a detailed "how to" in the Tech section in the "how to" thread.

I just recently learned of a trick here that will aid in reinstalling the skid. Perhaps this is common knowledge but I'd never heard of it before.

Use a small ratchet strap to collapse the suspension so the skid-assembly can be more easily inserted. Then undo and remove the strap once the skid is back inside the track/tunnel area.

I have not tried it yet but plan on taking some pics when I reinstall mine next Friday. On the road right now. In theory it sounds like a great idea. I've fought with it before doing it the old fashioned way....the push, pry, cuss, and cry method.
