The Jones Racing Products HTD Crankshaft Pulley 18 Tooth 1-1/8" ID with 1/8" Keyway (part number CS-6102-A) is a precision-engineered serpentine drive component designed for marine engine builders and performance enthusiasts who require reliable power transmission. This pulley is ideal for applications involving superchargers, alternators, and raw water pumps in integrated drive systems.
Machined from aluminum and finished in black anodize, this HTD pulley ensures repeatable synchronization and minimal deflection, essential for high-RPM marine engines. The 18-tooth design features an 8mm pitch that securely engages with standard HTD belt runs, maintaining belt tracking without slippage during load spikes typical in marine service.
Engine builders upgrading existing systems or assembling custom powerplants will find this pulley suitable for a range of applications, from small-block V8 retrofits to larger displacement engines running multiple accessories. The 1-1/8" ID accommodates standard crankshaft journals, while the 1/8" keyway provides a positive rotational lock, critical during engine acceleration or when running auxiliary systems under load.
