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?

When I pulled my 4agze pulley i actually threaded two bolts into the pulley (they were there so you can use a pulley puller). I had my mom (she was the only one around at the time lol) hold a pry bar in it using those two bolts and then i went to town with big prybar; Keep in mind that I didn't care what happened to this pulley as i was swapping it out. Since you've already tried something like this though...

Another thought that may work would be to have someone hold the brakes down while its 'in gear'. That should keep the pulley from turning as well and probably a bit more elegant then using brute force to get it done.

Sorry I guess I just glanced at your post before
