Devout Dirtbag
Trying to remove cranks from early 1990s giant stone breaker to fix wobbley crank problem. Lefthand crank comes off OK with standard crank puller. But at driver side crank the crank puller is actually pushed out of the threads when the crank puller is turned. Clearly, there is something up with the crank threads. Is it worth trying a different crank puller? Is it worth hitting the chain wheel with a wooden mallet to try to get the cranks to settle back into the bottom bracket? The locking nut behind the chainwheel appears to be absent. Your thoughts please.
