China OEM Serpentine Idler Pulley Factory - alternator clutch pulley F-585322 – RNA

Since all pulley types are not interchangeable,   Therefore, it is important to use only the type of pulley originally equipped with the vehicle. Therefore, if the vehicle requires solid pulleys, OWC or oad, pulleys of the same category must be installed. Like any other component, overrun alternator pulleys will not last forever (technicians will replace more and more pulleys). Worn pulleys can cause vibration in the belt drive system and usually cause damage to the tensioner.

Check the quality of the generator through the appearance and clearance, swing the generator from front to back, left to right, and judge whether the direction of the front bearing and the clearance become larger. If the axial direction and clearance change, it indicates that the generator is faulty. The one-way wheel of the generator is used to alleviate the impact of the engine when the vehicle accelerates or decelerates rapidly, and adjust the power generation. After the one-way wheel of the generator is damaged, the vehicle has no buffer during rapid acceleration or deceleration, which will produce abnormal noise when starting, and the engine will also produce abnormal noise when gently stepping on the accelerator. After the one-way wheel of the generator is damaged, it needs to be repaired in time, otherwise the vehicle battery will not be charged, and insufficient battery power will lead to weak driving and flameout of the vehicle.
