What do you use to strip a crank on a bike?

Answer 1

If this is about a bicycle it'll depend on the style of crank you have. Maybe an Allen key or two, maybe a socket wrench, a crank puller, a pedal wrench. Then whatever tools your bottom bracket requires, there's a few options there too.

If this is about a motorbike, it's a hopeless question. There are too many steps involved in stripping an engine crank for it to be covered here. Many of them would be specific to your exact engine as well.
