Heil Quaker ICP 1171426 Motor Pulley

The Heil Quaker ICP 1171426 Motor Pulley is a high-grade variable pitch sheave designed for precise HVAC blower speed adjustment in commercial and residential fan-drive systems. As a genuine ICP OEM replacement part, this cast iron pulley features a robust 1VL40x5/8 configuration, providing a 5/8-inch finished bore with a standard keyway for secure attachment to the blower motor shaft. The 3.75-inch outside diameter enables contractors to fine-tune system static pressure and airflow delivery by adjusting the pitch, making it an essential component for balancing ICP packaged units, heat pumps, and air handlers.

Built for durability in high-demand environments, the 1VL40 series sheave is compatible with 3L, 4L, 5L, A, and B section V-belts. By utilizing an adjustable motor pulley, technicians can compensate for varied ductwork resistance without replacing the entire drive motor. This part is a direct cross-reference for various International Comfort Products brands, including Heil, Tempstar, and Comfortmaker, ensuring a perfect fit and maintaining the original mechanical efficiency of the drive assembly.
