I have an electric 350 ft-lbs impact wrench which used to change tire. It did not loosen the bolt.
I put a 3″ socket extension though one of the pulley holes. With the help of a long pipe over the breaker bar, I was NOT able to break the bolt loose. But I bent the socket extension in the process. Tomorrow, I will find something stronger to wedge the pulley.
I was turning the pulley bolt in counter-clockwise direction. Am I correct?
