Oil Pump Pulley HTD 32 Tooth 1-1/4in Wide

The Oil Pump Pulley HTD 32 Tooth 1-1/4in Wide is a precision-engineered crankshaft accessory designed for high-performance engine builds and mechanical restorations. This HTD (High Torque Drive) pulley synchronizes oil pump rotation with engine speed, ensuring consistent oil delivery under demanding conditions. Whether you're upgrading a carbureted V8, rebuilding a vintage street machine, or fine-tuning a modified engine platform, this pulley serves as a critical timing component that directly impacts lubrication reliability and engine longevity.

Constructed from aerospace-grade aluminum and finished in black anodized coating, the HTD pulley delivers superior corrosion resistance and lightweight performance for engine bay applications. The 32-tooth HTD profile ensures positive belt grip without slippage, eliminating common issues associated with worn V-belt pulleys that cause oil starvation at high RPM. The 1-1/4 inch width accommodates standard HTD belt configurations, while the 5/8 inch shaft diameter integrates seamlessly with most conventional oil pump shafts. The compact 4.3 x 1.95 x 5.9 inch footprint and featherweight 0.42 lb design minimize parasitic load on the crankshaft while maximizing heat dissipation through anodized surface treatment.

Mechanics and engine builders favor HTD pulleys when upgrading belt-driven accessory drives on performance engines, race applications, and restorations where oil delivery consistency is non-negotiable. This pulley pairs with HTD serpentine belt kits to replace outdated V-belt systems, improving efficiency and eliminating belt slip that compromises oil pressure. Verify 5/8 inch shaft compatibility and HTD belt width before installation; this component is ideal for small-block and mid-sized engine platforms running sustained high-RPM operation or turbo/supercharger packages requiring robust oil supply.
