Who knows how to remove a?

Question

Well i have a crank extractor and a crank puller. But the bike i am trying to remove the crank from has a big bolt. The crank extractor fits the bolt but i can't turn it.It's a universal bike, but the bolt just wont move. Any ideas on how i can get the crank off? It is a square bolt aswell

Thanks

Answer 1

It All depends.. If it is the left crank, you will have to turn it so you think it is tightening, turn it clockwise and it should come off.

Answer 2

Sounds like a one piece crank.  The big nut on the left turns clock wise to remove (left hand threads).
