here is the deal the bolt backed off of the clutch and spun. i cant get the clutch hub to go on the crank far enough. the crank is tapered and i dont know if the hub is junk or the crank or both. there is little apparent damage to either. can someone please measure a known good crank at the largest and smallest parts of the taper. same with the clutch hub? a simple dial caliper measurement would be great. why the hell they didnt just use a woodruff key to locate the clutch? oh well, thanks for all that reply.
