HTD Oil Pump Pulley 36t

The Peterson Fluid HTD Oil Pump Pulley 36t is a precision-engineered timing component designed for high-performance engine builders and rebuilders who demand reliable fluid delivery and synchronization. This HTD (High Torque Drive) pulley serves as the critical interface between your crankshaft and oil pump, ensuring consistent volumetric flow at varying RPM ranges. Whether you're assembling a street engine, race application, or restoration project, this 36-tooth pulley is essential for maintaining proper oil system dynamics and preventing cavitation issues that compromise bearing protection.

HTD belt drive systems offer superior positional accuracy and load distribution compared to serpentine or gear-driven alternatives, making them the go-to choice for competition engines and custom builds where oil pressure stability is non-negotiable. The Peterson 36-tooth configuration is engineered to work within optimized gear ratios that balance pump displacement, crankshaft speed, and system pressure targets—preventing over-pressure conditions that can damage seals while maintaining adequate flow under peak demand. Manufactured to exacting tolerances with a compact 5.1 x 1.2 x 5.1 inch footprint and lightweight 0.4 lbs construction, this pulley integrates seamlessly into tight engine bay layouts without sacrificing durability or performance. The HTD tooth profile ensures positive belt engagement, eliminating slippage and guaranteeing synchronized pump operation across the full RPM spectrum.

This component is ideal for engine builders upgrading from stock stamped pulleys to a modern drive system, as well as restoration enthusiasts retrofitting vintage platforms with contemporary pump technology. Compatibility depends on your oil pump displacement and crankshaft pulley configuration—verify your pump manufacturer's specification sheet and belt pitch (typically HTD 8mm or 14mm) before ordering. Installation requires proper belt tension and alignment with matching crankshaft and accessory drive pulleys; most experienced mechanics complete fitment in under an hour. The Peterson Fluid HTD Oil Pump Pulley 36t represents a fundamental upgrade for anyone serious about engine reliability, oil system efficiency, and professional-grade assembly standards.
