The pulley is bolted onto the air pump after the pump is mounted. Depending on your belt alignment, the pulley can be installed to match up with the front or rear groove in the power steering pump pulley. The position shown is for the front pulley, but depending on the belt arrangement, the pulley can be reversed to line it up with the rear groove, as indicated by the factory installation. Since belt lengths varied in the original installation, the belt isn't included in the kit. Simply measure the length of the belt needed to drive off the power steering pump and order one from your local auto parts store.
