    Soak it in oil, put on puller tool, tighten it with Allen key as much as you can, the whack at the Allen key with a hammer
  • tryed that still no luck

    What type of crank and bb? Maybe try cycling it with the pinch bolts undone to loosen it up a bit. Failing that, whack it harder. Rubber mallet

    Bigger hammer. Always go for a bigger hammer.

    Cut them off.......small cut across the end of the crank and it will split and open up.
