HTD Oil Pump Pulley 40t

The HTD Oil Pump Pulley 40t from Peterson Fluid is a precision-engineered component designed for high-performance engine oil circulation systems. This 40-tooth pulley synchronizes with HTD (High Torque Drive) belt systems to regulate oil pump speed and flow rate, making it essential for both naturally aspirated and forced-induction engines that demand consistent oil delivery under varying RPM conditions. Whether you're building a street engine, race car, or restoring a classic with an upgraded cooling system, this pulley ensures your oil pump operates at the correct mechanical advantage.

Manufactured from lightweight aluminum and finished in gray anodize for corrosion resistance, the HTD Oil Pump Pulley 40t features a 5/8-inch shaft diameter and 1-inch belt width to match standard HTD belt specifications. The 40-tooth configuration provides optimal gear ratio for oil pump efficiency, reducing parasitic drag while maintaining adequate pressure across idle, cruise, and full-throttle operation. Gray anodized aluminum construction delivers durability without adding unnecessary weight, critical in applications where every fraction of a horsepower matters. The compact footprint (4.8 x 5.1 inches) allows integration into tight engine bay configurations without requiring extensive modifications.

This pulley is ideal for engine builders, performance shops, and enthusiasts who are upgrading or customizing their lubrication systems. It pairs seamlessly with Peterson Fluid oil pumps and HTD belt-driven accessory kits, particularly in small-block and mid-sized engine builds where serpentine or custom belt routing demands precise pulley geometry. Installation requires verification of shaft diameter and belt width compatibility with your pump assembly and belt system. The 0.42-pound weight makes it suitable for weight-conscious racing applications without compromising structural integrity or load-carrying capacity.
