Gilmer Oil Pump Pulley 32t

The Gilmer Oil Pump Pulley 32t from Peterson Fluid is a precision-engineered component designed for engine builders and high-performance automotive enthusiasts who demand reliability in their cooling and fluid circulation systems. This aluminum pulley functions as a critical drive component in serpentine belt systems, transferring rotational force to the oil pump while maintaining consistent speed ratios across multiple engine accessories. The 32-tooth configuration is engineered to work with standard Gilmer-profile belting, making it an essential upgrade for custom engine builds, race applications, and vintage hot rod restorations where OEM pulleys may not meet performance or aesthetic requirements.

Constructed from lightweight aluminum and finished in gray anodized coating, the Gilmer Oil Pump Pulley 32t delivers corrosion resistance and durability in high-temperature engine compartments. The 5/8-inch shaft diameter accommodates standard oil pump shafts, while the 1-inch belt width ensures proper grip and load distribution across the Gilmer-profile belt. Anodizing protects against oxidation and extends component lifespan, critical for engines subjected to extended operation, frequent temperature cycling, or harsh conditions. The compact dimensions (4.3 x 1.25 x 4.6 inches) and lightweight construction at 0.44 pounds minimize rotating mass, reducing parasitic drag on the engine and improving overall efficiency.

This pulley is ideal for engine builders integrating aftermarket accessory drive systems, small-block Chevrolet builds, Ford performance engines, and custom serpentine belt configurations where precise pulley ratios are critical. Installation requires alignment with matching drive pulleys and proper belt tensioning to ensure smooth operation and prevent premature wear. The 32-tooth design works in concert with other Gilmer-profile pulleys to maintain correct alternator charge rates, water pump flow, and oil circulation at target RPM ranges. Verify shaft diameter and belt profile compatibility with your specific engine platform and accessory drive package before purchase.
