How does the crank work on a bike?
Besides being strong enough translate explosive linear forces into rotation, a crank also determines when the pistons of a multi-cylinder engine go up and down, which in turn determines the level of vibration, the type of noise it makes and how the bike grips. Take an old Brit twin like a 1960s Triumph Bonneville, for example.

This started to pull the bearing and gear off but you will still need the pres to finish the job. Once you transfer the crank over to the press put a socket or some othe protecter onto the end of the crankshaft so you won’t damage the end.
