Tearing into the magnum over the last few weeks has led me to taking apart the clutch. I've had my fair share of clutches apart, and the powerbloc seems to be pretty simple and effective. But, the stationary sheave does not want to come off the engine, and the secondary doesn't want to come off the transmission input shaft. So, I know the primary is going to need a bit of work even if I can get it off the engine.

Since I will need to get a PTO shaft and plate made for the yanmar, I was thinking if I use a snowmobile clutch, I can get the PTO made as a tapered shaft.

Any thoughts on this? Anyone?
