OK so I've begun the restore on the 8163 I just acquired. I knew from the owner that it was missing a couple of rollers for the right hand clutch cam. So this morning I pull off the clutch - yup no rollers and the bearing is shot and the cam is cracked. Luckily I found an assembly to replace it. Though I'll probably see if the crack can be brazed and rebuild it for a spare.
Now the other problem is either a problem or lack of understanding on how the transmission and clutch system works.
So the right side piece that the clutch pushes against to get traction spins freely the left side doesn't. This doesn't seem to make sense to me. Can somebody explain how this works? Does which side is free wheeling or not depend on the shift levers? right now I think everything is in neutral.
