I am in the process of replacing the timing belt on a 2002 Accent. I am at the point of trying to remove the pulley on the crankshaft. Its held on with a bolt, which is on quite securely. Is there any secret on how to keep the shaft/pulley from turning while trying to loosen the nut?

 

Air ratchet or impact gun.

 

Impact and socket (use a black 6 point impact socket)
