are you using two breaker bars?! use one to hold the pulley with the tool, use the other with a short extension (3 in.). make sure the breaker bar has enough swing by jacking up the car. make sure the pulley holder is tight on part of the body and use your foot to push the shit out of the breaker bar. if that ain't doing much, start kicking it with the center of your foot. if that shit wont come off, it aint!! LOL!!
