I learned a really cool trick, I was having a really tough time getting the pilot bearing out of the back of the crank. I don’t have a puller, so I watched a video of people putting grease, wet bread, or peices of wet paper in and then hammering it in. So I used paper, jammed a bunch in, hammered, jammed more in, and hammered. You just need a bolt that fits snug in the inner race. Low and behold it pushed it out!
