HTD Oil Pump Pulley 34t

The Peterson Fluid HTD Oil Pump Pulley 34t is a precision-engineered component designed for serious engine builders and performance mechanics who demand reliability in high-rpm applications. HTD (High Torque Drive) pulleys transfer power from the crankshaft to the oil pump with minimal slippage and maximum efficiency, making them essential for custom engine builds, race applications, and modified street engines where stock serpentine systems fall short. This 34-tooth aluminum pulley fits 5/8-inch shafts and maintains the 1-inch belt width standard, allowing seamless integration into both naturally aspirated and forced-induction platforms.

Constructed from aluminum and finished in gray anodized coating, the HTD Oil Pump Pulley 34t delivers superior durability while resisting corrosion and oxidation in high-heat engine bays. The 34-tooth profile provides optimal gear ratios for maintaining consistent oil pressure across varying engine speeds—critical when running high-lift camshafts, increased displacement, or elevated boost levels that demand aggressive oil circulation. At just 0.34 lbs, the lightweight design minimizes rotational inertia, reducing parasitic drag on the crankshaft and freeing horsepower for actual wheel output. The gray anodized finish is both functional and aesthetically refined, complementing modern engine bay presentations.

This pulley is ideal for engine builders upgrading fuel injection systems, turbocharger installations, or custom pump configurations where timing and flow precision matter. Mechanics working on LS platforms, small-block Chevys, Ford Windsor builds, or any modular engine project will appreciate the Peterson Fluid reputation for quality and exact fitment. Installation requires a compatible HTD belt and proper shaft alignment; verify your oil pump bore diameter and belt width before ordering to ensure proper meshing and longevity.
