Oil Pump Pulley HTD 36 Tooth 1-1/4in Wide

The Oil Pump Pulley HTD 36 Tooth 1-1/4in Wide is a precision-engineered timing component designed for marine and automotive applications where reliable fluid circulation is critical. Built by Jones Racing Products, this pulley drives the oil pump through synchronous belt drive, ensuring consistent oil delivery to engine components under demanding operational conditions. Whether you're running a high-performance marine engine or a custom automotive build, this HTD pulley delivers the timing accuracy needed for proper lubrication and engine longevity.

Manufactured from aluminum and finished in black anodize, this pulley features 36 teeth machined to HTD (High Torque Drive) profile specifications for positive engagement with matching belts. The 1-1/4 inch wide face accommodates standard HTD belts, while the 5/8 inch shaft diameter provides a secure, interference-fit connection to oil pump drives. The anodized aluminum construction resists corrosion and heat degradation—essential protection in salt-water marine environments where moisture and thermal cycling accelerate component wear. At just 0.46 pounds, the lightweight design minimizes rotational inertia while maintaining structural rigidity under load.

This pulley is ideal for builders upgrading oil circulation systems on race engines, performance marine powerplants, or custom automotive projects requiring precision belt-drive timing. The HTD 36-tooth profile ensures positive no-slip operation even under sustained high RPM—critical for maintaining oil pressure in engines that see prolonged acceleration or sustained throttle conditions. Verify shaft diameter, belt width, and HTD profile compatibility with your existing pump and belt system before ordering. Installation requires standard pulley mounting hardware and proper belt tensioning to achieve rated performance.
