HTD Crank Driven Pulley

The Peterson Fluid HTD Crank Driven Pulley (Part No. 05-1218) is a precision-engineered timing component designed for high-performance engine builds and serious mechanical work. This OEM-quality pulley synchronizes crankshaft rotation with accessory drive belts, making it essential for any engine that demands accurate ignition timing and reliable auxiliary power distribution.

The HTD profile teeth on this Peterson pulley engage precisely with HTD timing belts, eliminating slip and ensuring rock-solid synchronization under all load conditions. HTD technology distributes torque more evenly across the belt surface than traditional V-belt designs, reducing wear on both the pulley and belt while allowing for tighter tensioning without premature failure. The compact design—measuring 2.85 inches in diameter with a 4.35-inch face width—fits within tight engine bays while maintaining the structural rigidity needed for high-RPM applications.

The minimal weight of 0.12 lbs keeps rotating mass low, critical for engines where every fraction of an ounce affects parasitic drag and responsiveness. Mechanics and engine builders rely on Peterson pulleys for both stock restorations and modified applications where original components have worn beyond safe limits. This HTD Crank Driven Pulley is an ideal choice for anyone looking to enhance engine performance and reliability.
