A belt pulley for a power steering pump is a rotating component attached to the pump shaft. Its function is to transfer engine power via a belt to drive the power steering pump, enabling hydraulic assistance for steering.
Key specifications include pulley diameter, number of grooves, mounting type, material, and compatibility with the belt system. It must ensure proper alignment and withstand continuous rotation and load.
Replacement is necessary when the pulley is worn, bent, damaged, or misaligned. Common symptoms include noise, belt slipping, or reduced steering performance.
