The pulley mounts on the alternator shaft and is driven by the engine accessory belt, spinning the alternator to generate electrical power for the vehicle. Over time, the pulley can wear, develop cracks, or cause belt noise and slippage, leading to charging system problems. Replacement is necessary when the pulley is worn, noisy, or damaged to restore proper charging performance.
