I'm working on taking the motor out of one of my wheelers, and I can't get the last bolt out that goes thru the swingarm. I've had the wheeler on the side for the last three days and I've been pb blastering it 5 times a day. I have the nut off, and the bolt will turn, but it won't come out. I've tried pounding it out by turning the nut on a bit and putting a punch in the middle. Would heating up the outside of the swingarm/engine area be a good idea??? There's bushings in there that would melt I'd assume, but I just want to get it out.... Any thoughts????
