The best repair is to have the crank arm threads re-tapped to a larger size and install a PTO cap. This way the crank is restored to it's original condition as is easy to remove again and again.The tool is expensive to buy so you'll probably want to find a shop that will do it. Here is a link so you can see what these tools look like, there are a couple versions: http://www.biketoolsetc.com/index.cg...item_id=SN-CES

I you just want the arm off and aren't worried about it's condition you can put bolt in just a couple threads and go ride it carefully until it works it's way loose.

Pickle forks and gear pullers can work in some situations.

Search for it. There are 3-4 different methods described.

What kind of BB is it? Do you want to reuse the cranks/bb?
