This pulley is fitted onto the alternator so the internal rotor assembly can be turned within the stator to create output voltage. If the pulley has become damaged and no longer turns on the alternator correctly, it's time for a replacement to keep your charging system operating properly.
Some alternators do not include a new pulley and must be removed from the old component. Save yourself time by picking up a new pulley.
