Gilmer Oil Pump Pulley 36t

The Gilmer Oil Pump Pulley 36t from Peterson Fluid is a precision-engineered serpentine belt pulley designed for high-performance engine oiling systems. This component serves as the driving interface between your engine's crankshaft and the oil pump, ensuring consistent oil circulation and pressure regulation throughout the engine block. Built for builders, restoration specialists, and performance enthusiasts who demand reliable fluid delivery systems, the 36-tooth Gilmer pulley is essential for maintaining optimal lubrication in custom and modified engines where standard components fall short.

Constructed from lightweight aluminum and finished in gray anodize for corrosion resistance and durability, this pulley features a 5/8-inch shaft diameter and measures 1 inch in width—specs that integrate seamlessly with Peterson's modular pump systems and aftermarket belt-drive configurations. The 36-tooth design provides optimal gear ratio engagement with matching drive belts, delivering smooth power transfer while minimizing slip and heat generation. The gray anodized finish protects against oxidation and wear while maintaining a professional appearance on display engine builds. Weighing just 0.49 pounds, the aluminum construction keeps rotating mass minimal, reducing parasitic drag on the engine.

This pulley is ideal for custom engine builders integrating Peterson's oil pump systems into hot rods, race engines, and specialty vehicles where serpentine or Gilmer belt drives replace traditional chain-drive configurations. Compatibility depends on your oil pump model and belt width—confirm that your pump's input shaft accepts a 5/8-inch bore before purchase. Installation requires proper pulley alignment and belt tension adjustment to prevent premature wear and ensure reliable oil delivery. Whether you're building a competition engine or restoring a classic with modern cooling and lubrication upgrades, the Gilmer Oil Pump Pulley 36t delivers the precision fit and dependable performance that serious builders expect.
