My crank pulley wobbles noticably when the motor is running. I was wondering if the pulley can be balanced or adjusted in any way.

 

If it is just the pulley replace it.......if it is the harmonic balancer the retaining rubber could be bad, that too should be replaced. I think someone used the crank pulley to block up the engine not knowing it weighs 1000lbs+......now it is bent.
