you will need a 3-arm puller, a tool with 3 arms attached to a central nut, the arms grab the clutch or whatever, and you screwin a bolt through the nut to pull the arms back. the bolt pushes against the crankshaft and the arms pull the clutch. it should be held on due to a groove in the shaft and clutch, with a piece of metal jammed in holding them together.
