HTD Oil Pump Pulley 36t

The Peterson Fluid HTD Oil Pump Pulley 36t is a precision-engineered aluminum component designed for high-performance engine oil circulation systems. Built to OEM specifications, this HTD (High Torque Drive) pulley features 36 teeth, a 5/8-inch shaft diameter, and 1-inch belt width, making it compatible with synchronous belt-drive configurations used in racing engines, marine powerplants, and performance automotive applications where reliable oil delivery under sustained load is critical.

The 36-tooth HTD profile ensures positive drive engagement without slippage, a key advantage in high-RPM applications where conventional V-belts or flat pulleys cannot maintain gear-ratio accuracy. The gray anodized aluminum construction provides corrosion resistance and reduced weight compared to cast iron alternatives, critical for systems exposed to coolant spray, saltwater environments, or prolonged high-temperature cycling. The 5/8-inch shaft bore accommodates standard oil pump drive shafts, while the 1-inch belt width matches HTD-36 belt specifications, ensuring proper meshing and load distribution across tooth contact surfaces.

This pulley is engineered for builders and technicians upgrading or restoring performance-driven systems—race engines, marine propulsion platforms, and off-road powerplants—where stock oil pump pulleys cannot sustain required flow rates or reliability margins. The HTD profile is favored in these applications because it transmits higher torque than serpentine systems while maintaining consistent pump speed across varying engine loads, ensuring stable oil pressure delivery to critical bearing surfaces during sustained acceleration or sustained operation.

Peterson Fluid is recognized for manufacturing OEM-level pulleys and drive components used in factory racing programs and aftermarket engine builders. Proper installation requires alignment with the mating crankshaft or drive-shaft pulley to prevent uneven wear. Verify belt compatibility and shaft bore fit before installation.
