Got an EXT that the flywheel just won't come off - already stripped the threads off a harmonic puller and ruined 2 sets of bolts.

Any tricks? How hot can I get it without damaging anything?

are you tapping the end of the puller with a hammer as you tighten it up ?

was "tapping" (beating the snot out of it) pretty good - had a 3ft bar on the harmonic balancer and 3ft bar in on the socket twisted the 3 bolts back and forth until the were spaghetti, I was amazed they didnt break but at $8 a set I quit after 2 sets. I also was shooting it with PB.

make sure the puller is bolted up tight to flywheel.keeps tension even on all three bolts. tighten puller bolt tight and smack with bfh. repeat, repeat,and repeat till somthing gives. i went through 3 sets of bolts.

Problem is you need grade 8 bolts Off the top of my head I think there 6mm X 1.0 but they have to be grade 8 bolts the ones you buy at the hardware store are not going to cut it they break too easy. You get the bolts on there thread them in as far as they go you want as much thread in as you can. Then tighten it down and tap the puller with a hammer might take a while sometimes you might have to leave the puller tight on there for a while then tap on it. Sometime the fly wheel comes off right a way other times its a battle. You just got keep tightening and tapping the puller with a hammer it sucks but they come after a while.
