The product includes the pulley unit; check your packaging as some kits may include a protective cap.
No, installation requires a specialized alternator pulley tool to hold the shaft while turning the pulley.
Common symptoms of a failing pulley include loud belt noise, excessive vibration in the belt tensioner, or a charging system warning light.
It is compatible with 6-rib belt systems, but you must ensure the shaft diameter and offset match your specific alternator model.
An overrunning pulley allows the alternator to 'freewheel' when the engine slows down, whereas a solid pulley is permanently locked to the shaft, which can cause excessive belt stress.
Check if the pulley has seized; if it does not spin freely in one direction, replace the unit immediately.
Ensure you are using the correct splined socket tool specifically designed for overrunning alternator pulleys.
Before installation, verify the part number against your existing alternator's specific code, as manufacturers often supply multiple alternator variations for a single engine.
