As simple as this should be I think I f'd it up. Rented the tool to install the pulley on the new pump and I thought it was seated well went I went to press on the pulley but evidently the threads on the tool did not match right with the threads on the pump and it stripped it out! Now don't know what to do. Tool doesn't work, pulley is stuck. Guess I need a new pump and pulley AGAIN!!?!! Help!
