An alternator pulley is a mechanical part that is mounted on the alternator shaft of a vehicle and is driven by the engine's accessory belt. The alternator pulley is usually round in shape and has a groove for the accessory belt. Its role is to transfer mechanical power from the engine to the alternator, which converts this energy into electrical energy to recharge the vehicle's battery and power the electrical systems.

There are different types of alternator pulleys, including single groove, double groove, V-groove and V-groove pulleys depending on the characteristics of the accessory belt. It is important to ensure that the alternator pulley is compatible with the engine accessory belt for optimal operation of the vehicle's electrical system.
