HTD Oil Pump Pulley 37t

The Peterson Fluid HTD Oil Pump Pulley 37t (PTR06-1337) is a precision-engineered serpentine drive component engineered for street and competition engine builds where oil pump reliability and timing synchronization are critical. This 37-tooth HTD (High Torque Drive) pulley is designed for engine builders and mechanics who demand consistent oil delivery at varying RPM ranges, particularly in modified or high-output applications where stock pump pulleys introduce parasitic loss or timing inconsistencies. Built to OEM specifications, this pulley ensures your engine's lubrication system operates at peak efficiency regardless of boost, displacement, or induction modifications.

HTD belt profile technology delivers positive engagement between belt and pulley teeth, eliminating slippage and ensuring accurate oil pump speed relative to crankshaft rotation—essential for maintaining stable oil pressure under load. Peterson's manufacturing tolerances guarantee concentric bore alignment and uniform tooth geometry, preventing harmonic vibration and premature belt wear that compromise both pump longevity and engine diagnostics. At 0.45 lbs with compact dimensions (4.7 x 1.7 x 4.95 inches), this pulley integrates seamlessly into tight engine bays while maintaining the structural rigidity required for turbocharged or supercharged applications where accessory drive loads spike significantly.

Street and competition builders rely on Peterson oil pump pulleys to maintain consistent PSI during acceleration, cornering, and sustained high-RPM operation—scenarios where marginal pump speed variation causes starvation in tight valve clearances or forced-induction circuits. This pulley is ideal for LS, small-block Chevy, Ford Windsor, and modern modular platforms utilizing HTD serpentine systems. Installation requires belt routing verification and tensioner adjustment per engine specification; consult your build documentation or service manual to confirm pulley compatibility with your existing balancer, water pump, and alternator configuration before ordering.
