I have the special Moroso tool for the crank to remove the crank pulley bolt of you don't have any air tools. It's a big hex shaped socket with a tang that comes off the side to put a 1/2 inch braker bar into, and it 's hollow so you can stick another socket in the middle to break the crank pulley bolt loose, while you hold the pulley from turning, it costs 45 dollars and I bought it at summit
