PCM Accessory Drive Pulley | 97950

PCM Accessory Drive Pulley | 97950

Maintain correct belt routing and accessory drive performance with this OEM-specification pulley for PCM inboard engines. Pulleys in the accessory drive system carry the serpentine belt that powers the alternator, raw water pump, and other engine accessories. A pulley with a worn bearing, cracked flange, or incorrect groove profile causes belt misalignment, vibration, and premature belt failure problems that compound quickly on a running engine.

Built to PCM specifications, this pulley is machined to the correct diameter, groove profile, and bore for its position in the drive system, ensuring the belt tracks true and loads are distributed evenly across all driven accessories.

Best Use Case

Best suited for replacing a damaged, corroded, or noisy pulley in the PCM accessory drive system during belt service, accessory replacement, or any time a bearing inspection reveals play or roughness. Also the correct replacement when a pulley flange is cracked or the groove is worn to the point of causing belt slip or squealing. Commonly replaced as part of a complete accessory drive service on higher-hour engines alongside the belt and tensioner.

Parts Desk Insights

Confirm fitment using your engine model and serial number before ordering PCM engines use different pulley configurations depending on the accessory layout and model year. A related pulley, PCM Accessory Drive Pulley 97954, is also available and may be the correct part for a different position in the same drive system. When replacing a pulley, inspect the belt and tensioner at the same time see the PCM Belt Tensioner RA068002 for the companion tensioner. Check for bearing play and roughness by spinning the pulley by hand with the belt removed; a smooth spin with no lateral movement confirms the bearing is serviceable.
