Can't remove the crank from BB.

I'm trying to remove a Miche Advanced crank from my bike but I can't get the damn thing off the BB. The BB is a Miche as well and it's a simple system, a bolt for each arm. I removed the bolts and the arms won't come off the BB. What is the best way to remove them? I don't want to hammer them and risk bending or denting the cranks. Any suggestions?

You're not an idiot. The idiot would've started banging on it then asked questions.

There are times when a crank puller will not loosen an arm from the shaft. Life becomes more challenging at that point. Todd Downs' book recommends removing the bolt and riding the bike until the arm loosens by itself. Some criticize this approach because it can damage the crank arm's fit.

When you use the puller, but certain it threads all of the way into the threads on the arm. Otherwise, the threads may well strip. Then the problems increase, too.

If it was a cheap bike I would bang away with a hammer and cold chisel.

But that marks the crank arms

I learned about the crank puller AFTER pulling off my first crank arm. Fortunately, it was on an old beater bike. At least you were smart enough to ask first.
