Source1 2809570700 Sheave Pulley 1 Groove 5.75 Inches Od 1 Inch Bore Fixed AK59 Belt

Product Description

The Source1 2809570700 is a fixed sheave and pulley designed for use in HVAC systems where reliable belt-driven power transmission is essential. This single-groove sheave features a 5.75-inch outer diameter and a 1-inch bore, making it a direct-fit OEM replacement for a wide range of York and compatible HVAC units, including AC036X1034, 1FE0413, and 1LD0406 models, among others. The sheave is designed to work with an AK59 belt type, ensuring proper fit and function when replacing worn or damaged drive components in air conditioning and heating equipment. HVAC technicians rely on OEM sheaves and pulleys to maintain the correct torque ratio between the motor and the blower or fan assembly. A properly sized sheave controls the speed at which driven components spin, which directly affects airflow, system efficiency, and equipment longevity. Using an OEM-spec part like this one eliminates the guesswork that comes with aftermarket substitutes. The fixed configuration means the groove position does not adjust, providing a consistent, stable drive interface. With a single groove, this sheave is suited for single-belt drive systems commonly found in residential and light commercial HVAC equipment. The part measures approximately 6.35 inches in length, 6.2 inches in width, and 1.45 inches in height, with a total weight of approximately 2.02 pounds. Whether you are performing a routine belt drive service or replacing a damaged pulley after a belt failure, the Source1 2809570700 provides a dependable, manufacturer-designed solution that meets the original equipment specifications of compatible York units.
