The Moroso Gilmer-style crankshaft pulley is a 3/8-inch pitch, 1-inch wide pulley with 18 teeth, designed for positive-drive accessory and timing systems that use radius-tooth belts. It provides specified tooth count and width to engage matching belts and preserve synchronized motion between the crank and driven pulleys. Use this 3/8" pitch, 1" wide, 18-tooth pulley as a direct replacement when those dimensions are needed.
