In an engine overhaul, I'm having a problem removing the bolt securing the front pulley to the crankshaft. (this is unusual, other engines use a nut fastener) I have used an air wrench without success. (It applies enough force to cause some damage to the bolthead.)
Could this be a left hand thread, or just a frozen bolt?
I've been told to use WD40 and heat, but I need to know if I have a right hand thread.
