SOURCE: cherokee crank pulley removal/repair

the bolt in the center on the damper is contra thread. to get it off use an impact (electric or air powered). and for the damper it is shot. you will have to replace it with a new or used one from a junk yard.

thanks

It is a right hand thread and you usually need an impact gun. Take the fan out of the way, to give you more room, I have found that helps.

They are usually in there pretty tight. If drivable, you can have someone loosen it up with a shop air gun.
Thread is not reverse.
There is a second way to remove it...Use a solid 1/2" breaker bar with the correct size impact socket. You need to support it and brace it against the floor. Then "bump" the engine over Don't crank, just bump. The engine crank will unscrew itself from the bolt. Be careful doing this if socket and bar get loose they can damage you and stuff around the area where you're working. I use a pipe driven into the ground with a pair of vise grips attached to the breaker bar to keep it at the right height. (bar goes inside the end of the pipe)

"Heat" and air impact is the trick. Get it as hot as you can and hit it with air impact. Be careful not to burn yourself!

I hope this helps you, and I wish you luck with your repair.
