can't get the crank sprocket off

[siueclipse]

This deals with a 99 Eclipse GS.

Well, last night we worked till about 3am on the car. We tried for several hours to get the crank sprocket off. It just wont budge. The book says that it should just gently pull off and that if it doesn't, then use the harmonic balancer puller to get it off. Well, we probably had about 500 foot pounds of torque on this damn thing. It didn't come off, nor did it breakk. We lubed it, heated it up and yelled at it. We are at the point were we want to cut it off and just replace the damn thing.

Does anyone have any suggestions?

You didn't mention taking off the bolts..

J/K these HB's can be a bi*** sometimes. Try some penetrating oil behind the pulley and the crank. (If you can get past the damn timing cover.) Cutting it could damage the crank, try the puller again, while it has full tension on it, smack it from behind with a large punch and a hammer.

Many people use what is called the "bump" method to loosen the crankshaft bolt. To do this, you must either have the timing belt still on the car or have removed the camshafts (or the whole head, if you are in that position) so the valves are not open. The engine will rotate clockwise when the starter is engaged. To be safe, pull the MPI (Engine) 30A Fuse under the hood. Place the appropriate socket and breaker bar on the crankshaft bolt where the breaker bar is resting on the control arm. Put the key in the ignition and "bump" the starter.

I don't care for that method, so I make certain I have another person available. Put the car in 5th gear and have the other person hold the brakes hard. Try to use a cheater bar if available and give that bolt hell. This, unlike the bump method, works to tighten and torque the bolt as well.

Still others use pneumatic tools for quickest removal.
