cranckshaft pulley

[pollaso19]

I can't get the damn cranck shaft pulley out. I think the mechanic prior to me touching the car cross-threaded the threads on the cranckshaft.
I tried removing it with an impact wrench and the compressor set for 150 psi and nothing, it would'nt come out. Is their a special tool for the bolt or what. Its a 1990 Honda Accord coupe. And also some answer me this, is it a crankshaft pulley or a harmonic balancer, some people refer to it as one name and other to the other.

It is technically called a crankshaft damper.
Now, to loosen or remove the bolt. Does your air max out at 150? if so, you can remove the bolt manually as follows. First, if you have a 2.2 CID the install'n tightening spec=166FtLbs so 150Ftlbs you're applying won't budge it. Here's the way I remove them manually since I don't have air. First, completely secure the car with body jacks and remove the negative ground from the battery.Make sure the car is totally blocked at the wheels, emergency brake on, in park and the chassis adequately supported. Jack the front up and remove the driver's side front wheel.
Next, lock the damper down using an old belt from this pulley folded under itself and the other end secured to the frame. You can also buy the special tool to lock the damper. Now, attach a 6 point impact 3/4'" drive socket to the bolt. Run a round rod thru the damper to help serve as a stop. Secure the rod to the frame. Next connect a 24" 3/4" extension to the socket. Next, rest the female end of the extension on the top of a body jack so that the extension is level. This will serve as your fulcrum. Now attach a 3/4" breaker bar to the extension. DO NOT USE A 1/2" breaker bar as it will break the breaker bar. Next, place a 1" x 6' piece of black pipe over the breaker bar. Put on a full face shield to protect against a breaking tool. Put on a pair of leather gloves as it stings like h--- when the bolt breaks loose if you don't.
Set the socket so that the black pipe is at a 10 o'clock angle.
Finally, if all is ready, starting in the 10 o'clock position, GRADUALLY and SLOWLY apply pressure downward, using your body weight as torque. Be ready for it to break loose. You may have to apply as much as 600-800 lbs torque to break it loose. Do worry, you won't break the bolt. You'll hear a load snap and the breaker bar will drop down. It's easy going from there.
Good Luck,

Hey, I'm new but I watched my mechanic change my crank pulley to a lightened one. He had to use a cutting torch to heat up the bolt in order to "release" the thread-lock stuff on it. Then he wrenched like hell!
