I struggled getting my fan clutch off all afternoon with no solid progress. The nut won't seem to break loose and I can't get the pulley to stop spinning. I'm using a fan clutch set I rented with a 39mm wrench (fits on the nut perfectly), but I can't get either the 54mm or 57mm wrench to keep the pulley from spinning. I'm afraid that one of the bolts holding the pulley on are going to get stripped or sheared off.

Any advice is welcomed.
