Oil Pump Pulley HTD 33 Tooth 1-1/4in Wide

The Oil Pump Pulley HTD 33 Tooth 1-1/4in Wide is a precision-engineered belt drive component designed for high-performance engine builds and OEM pump replacements. This HTD (High Torque Drive) pulley synchronizes your oil pump rotation with your engine's crankshaft, ensuring consistent pressurized lubrication across all critical bearing surfaces. Whether you're restoring a classic engine, upgrading to a higher-flow pump, or fine-tuning a custom built motor, a quality oil pump pulley is non-negotiable for reliable long-term operation.

Machined from aluminum and finished in black anodized coating, this pulley offers exceptional durability while resisting corrosion and thermal stress. The 33-tooth profile and 1-1/4 inch belt width match industry-standard HTD timing belt systems, providing precise synchronization without slip or deflection under sustained engine load. The 5/8 inch shaft bore accommodates standard pump shafts, while the anodized finish protects against oxidation in high-heat engine bays. Compact dimensions (4.5 x 1.9 x 6.05 inches) and lightweight construction at 0.43 lbs make installation straightforward without adding rotational mass that could compromise engine efficiency.

Experienced mechanics and engine builders rely on HTD pulleys for street engines, race motors, and vintage restorations where reliable oil delivery is critical to bearing longevity. This component pairs seamlessly with matching crankshaft pulleys and timing belt systems on small-block and mid-displacement builds. Before installation, verify your pump shaft diameter and confirm HTD belt width compatibility with your engine's timing cover—proper belt tension and pulley alignment ensure years of trouble-free operation and consistent oil pressure across all RPM ranges.
