Crank bolt hard to loosen - 5sfe, SOLVED Options

[dgbldr]

I can't loosen the bolt on the front of the crank. It's on real tight.

I tried an air impact rated at 600 ft-lbs. No go. Not real confident it actually puts out that much torque, but still...

Also made a tool similar to the factory tool to hold the pulley. Long plate with 2 bolts through it into the threaded holes on the pulley. Torqued plate hard against pulley. Used cheater bar to turn crank bolt. No go, bent the 2 bolts. I estimate I put about 250-300 ft-lbs on it.

Has anybody run across this problem before and found a solution?

You can try that with the starter, or you can just try sliding a big pipe over your breaker bar. I remember it was on my 4agze really really tight. You either need an incredibly strong impact wrench or a long breaker bar (use leverage to your advantage).
