PCM Accessory Drive Pulley | 97954

PCM Accessory Drive Pulley | 97954

Keep your accessory drive system running true with a direct-replacement pulley built to PCM specifications. Pulleys in the accessory drive system guide and tension the serpentine belt that powers the alternator, raw water pump, and other engine accessories. A worn, cracked, or seized pulley causes belt misalignment, accelerated belt wear, and ultimately accessory failure often at the worst possible time.

This OEM-specification pulley is machined to the correct diameter, width, and groove profile for its position in the PCM accessory drive system, ensuring proper belt tracking and load distribution across all driven accessories.

Best Use Case

Best suited for replacing a damaged, corroded, or seized pulley in the PCM accessory drive system during belt service or accessory replacement. Also the right part when belt wear inspection reveals uneven wear patterns pointing to a misaligned or wobbling pulley. Commonly replaced alongside the belt and tensioner as part of a complete accessory drive service on higher-hour engines.

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 97950, 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. A seized or noisy pulley bearing is often the first sign of failure; check for play and roughness by spinning the pulley by hand with the belt removed before condemning it. For the alternator driven by this system, see the PCM 70-Amp Marine Alternator RA097007.
