Oil Pump Pulley HTD 40 Tooth 1-1/4in Wide

The Oil Pump Pulley HTD 40 Tooth 1-1/4in Wide by Jones Racing Products is a precision-engineered belt drive component designed for high-performance engine builders and serious vehicle modifiers who demand reliability in their custom fuel and oil circulation systems. This HTD (High Torque Drive) pulley is essential for upgraded oil pump assemblies, synchronizing pump speed with engine rotation to maintain consistent pressure and flow under demanding conditions.

Whether you're building a naturally aspirated stroker, preparing for nitrous oxide injection, or running forced induction, this pulley ensures your oil system keeps pace with increased horsepower and thermal loads. The 40-tooth HTD profile delivers positive, slip-free engagement with matching serpentine belts, eliminating the inconsistency and slippage problems common with V-belt pulleys on modified engines. The 1-1/4 inch belt width accommodates multiple load paths, distributing torque evenly while minimizing belt wear and heat generation—critical factors in engines where oil system reliability directly impacts engine longevity.

Jones Racing Products designs these pulleys with tight tolerances and precision machining, ensuring accurate timing and balanced rotation that prevents harmonic vibration during sustained high-RPM operation. The compact footprint integrates seamlessly into tight engine bays common in race cars and modern performance builds. Professional engine builders and serious modifiers will find this pulley an invaluable component in achieving optimal engine performance.
