Is it spinning on you? Pull off the passenger side plastic plate by the starter and expose the flywheel so you can put a screwdriver through it to wedge it. Then just get a big socket and wrench and a cheater bar and go to town. They are normal threads btw.

Oh and if you use a 15/16" socket (I think) it fit's almost perfect against the crank to push on with your puller.

And don't forget to get a new bolt, it's a one use only piece. And do not use a bolt to pull the pulley back on - use a threaded rod and nut and washers - do a search on here on crank thread nightmares from using a bolt.

Or use a impact gun for the easiest and quickest way if you have one .

Ive done both with a impact gun, taking it easy of course, and with a breaker bar and brute strength...

your gonna need a GOOD high torque impact and GOOD compressor. Your standard impacts arnt gonna be even close to knocking that bolt out.. i tried with a snap on impact on a 30 gallon compressor @110 psi lol (kinda small compressor for a impact but 20 psi over max rating lol) and a electric dewalt. they didnt do **** haha...

Big breaker bar here always worked fine. Impact gun would sure be easier though.
