I don't think it's been mentioned yet but here it goes. To save yourself the same problem of sourcing a new crank pulley cause no matter what you did yours got bent in the process of removal. Take a 5/8" nut and weld it directly to the crank pulley after removing the crank pulley nut. Then take a piece of 5/8" all thread that matches the nut threads and thread it all the way in til it bottoms out. Weld another nut on the end of that and hit it with an impact gun. Never bend another crank pulley again. Once the pulley is off cut the nut off and grind it smooth.
