Crank Pulley Gilmer 19T

The Peterson Fluid Crank Pulley Gilmer 19T is a precision-engineered crankshaft drive component designed for high-performance engine belt systems. This aluminum pulley delivers reliable power transmission in mechanical drive applications, offering the accuracy and durability demanded by engines requiring Gilmer-profile synchronous belt drives.

Built with a 19-tooth configuration and 3/8-inch pitch, this pulley maintains precise belt engagement and eliminates slippage under load. The 1.02-inch width accommodates standard Gilmer belts, while the 1-inch mandrel and 1/8-inch keyway ensure secure, repeatable mounting to the crankshaft. Finished in gray anodized aluminum, the pulley resists corrosion and wear while delivering the thermal stability required in demanding engine environments. These specifications translate to consistent belt tension, reduced vibration, and extended component lifespan in applications ranging from marine auxiliary systems to supercharger and water pump drives.

This universal pulley suits engine builders, mechanics, and restoration specialists who demand OEM-equivalent fitment and performance. Whether upgrading a street engine, marine installation, or performance build, the Peterson 19T Gilmer pulley provides the dimensional accuracy and material quality necessary for dependable belt-drive operation. Lightweight at just 0.3 pounds, it adds minimal rotational mass while maintaining the structural integrity required for sustained high-RPM service.

Peterson Fluid Systems has established a reputation for precision pump and drive components in automotive and marine markets, where tolerances and durability directly impact system reliability. The Crank Pulley Gilmer 19T reflects that standard—engineered for engines where synchronous belt performance is critical to operation.
