A clutch puller is a tool for removing a clutch from the end of a shaft (such as the crankshaft). It typically functions by fastening to the clutch and using a screw to exert pressure on the shaft to which it is mounted.
Puch Clutch Puller
"So, I don't know if you guys know already or not, but the handlebar mount of a Puch Maxi, and likely others doubles as a clutch puller. Simply pass the M6 bolts through the mount, and then place a socket, rock, or whatever you have between the mount and crankshaft as a press arbor. Now, screw down on those M6 screws until your clutch pops off. Trust me...works every time."
HINT: The stock mounting bolts on the bracket are M7s you're going to need to pick up 2 m6 bolts.
