Engine Mechanical problem
1989 Buick Electra 6 cyl Front Wheel Drive 150000 miles
I'm replacing the harmonic balancer (dampner) on my '89 Buick Electra front wheel drive 3.8l engine. I'm having difficulty removing the center bolt (only bolt) on the crankshaft pulley. I think it's torqued to about 220 ft lbs normally but I've bent 2 breaker bars, broken a torque wrench and also a socket trying to remove it. It's good and stuck. Could this be a reverse thread bolt? If not how do you feel about applying heat, being careful of the rubber mounting ring, of course? I don't want to risk snapping the bolt in half until I know it's not a reverse thread. Any other ideas would be appreciated. Thanks.
