I put my march underdrive pullies on and the crank pulley wabbles really bad. Is there a certain way to put the crank pulley on?
 
The bolt pattern has one hole slightly offset, so the pulley can only be installed in one position. I'm sure you have it on wrong and that's why it's wobbling.

Is your balancer bad? Like David said it only goes on one way so I am wondering if your balancer is broken.
 
i finally got it on there. good thing it was aluminum and not the stock one my arm would have fallen off from the weight.
