Alternator Pulley
The Alternator Pulley is a crucial component of the vehicle’s charging system. It is mounted on the alternator shaft and connected to the engine via the drive belt. Its primary function is to transfer mechanical power from the engine belt to the alternator, enabling it to generate electricity for charging the battery and powering the electrical systems of the vehicle.
A high-quality alternator pulley ensures:
Smooth rotation of the alternator
Reduced vibration and noise
Longer belt and alternator life
Efficient power transmission
Common types include solid pulleys and overrunning alternator pulleys (OAP), the latter designed to reduce stress on the belt drive system during acceleration and deceleration.
