HTD Oil Pump Pulley 37t

The Peterson Fluid HTD Oil Pump Pulley 37t is a precision-engineered aluminum component designed for high-performance engine cooling and lubrication systems. This 37-tooth HTD (High Torque Drive) pulley delivers synchronized power transmission with minimal slip, making it essential for builders working with forced induction or high-RPM applications where reliable oil circulation is critical to engine longevity.

Built from lightweight aluminum with a gray anodized finish, this pulley resists corrosion while maintaining excellent heat dissipation properties—a key advantage in engine bays where thermal management impacts both performance and durability. The 1-inch belt width accommodates standard HTD belt systems, while the 5/8-inch shaft diameter provides compatibility with common oil pump shaft sizes. The 37-tooth configuration balances belt grip and rotational efficiency, ensuring consistent oil flow rates across varying engine speeds without excessive drag or slippage that could compromise pressure delivery.

This pulley is ideal for engine builders, hot rod restorers, and high-performance enthusiasts who require OEM-quality drive components for custom cooling or dry-sump oil system installations. Whether upgrading a naturally aspirated engine or installing a supercharged package, the HTD profile ensures dependable synchronous drive without the slipping associated with V-belt systems. Proper pulley selection directly impacts oil delivery pressure, particularly in extreme-duty applications where marginal pressure loss can lead to bearing wear or system failure.

Peterson Fluid is recognized within the performance engine community for precision-manufactured drive components and cooling system accessories. When selecting an oil pump pulley, tooth count, belt width, and material composition all influence system performance. This 37-tooth HTD design from Peterson represents a proven specification across street and competition engines seeking reliability without compromise.
