HTD Crank Driven Pulley

The Peterson Fluid HTD Crank Driven Pulley (Part No. 05-1218) is a precision-engineered crankshaft pulley designed for engine builders and machine shops requiring accurate timing belt drive integration. This aluminum pulley features an HTD profile with 18 teeth and an 8mm pitch, delivering reliable synchronization in crank-driven applications where precise belt engagement and rotational control are essential.

Built from aluminum and finished in gray anodize, this pulley resists corrosion while maintaining the light weight critical for reducing parasitic drag on engine systems. The 1-inch mandrel diameter accepts standard crankshaft configurations, while the 1/8-inch keyway ensures positive drive transfer without slippage. At 1.02 inches wide, the pulley accommodates HTD belts with minimal runout, supporting both high-RPM and load-bearing applications. The compact design—measuring 2.85 x 1.25 x 4.35 inches and weighing just 0.12 lbs—integrates seamlessly into tight engine compartments without adding significant mass.

This pulley serves engine rebuild projects, marine auxiliary systems, industrial drive systems, and custom powertrain installations where HTD timing synchronization is required. Whether supporting serpentine belt arrangements on performance builds or serving as a primary crank drive element in specialized applications, the Peterson Fluid HTD pulley delivers the precision fit and durable construction that professional fabricators expect. The universal mounting pattern makes this a versatile choice for builders working across multiple platform configurations.

Peterson Fluid components are recognized throughout the automotive and powertrain industries for engineering accuracy and manufacturing consistency. This pulley's HTD profile and dimensional tolerance ensure compatibility with standard HTD belt systems, reducing installation variables and supporting reliable long-term operation in demanding duty cycles.
