Technical Information:
Function: The function of the over-running alternator pulley is to disengage and dampen the alternator from the rotational energy of the engine. This allows the accessory belt system to run more smoothly, minimize belt noise, and variation. Also, rotational inertia is decreased, lowering drive belt slippage during deceleration and hard acceleration. Long term the over-running alternator pulley gives reduced stress on accessory drive belt components.

Diagnosing: Accessory belt (aka serpentine belt) problems can be easily misdiagnosed, particularly those with an over-running alternator pulley. After hearing belt noises coming from the accessory belt area and upon visual inspection, many notice excessive belt and tensioner vibration and flapping. Oftentimes this is misdiagnosed as a bad belt and weak accessory belt tensioner spring. In most cases the excessive belt vibration and flapping is caused by the over-running alternator pulley going bad.
