Source1 2813378000 Sheave Pulley 1 Groove 6.75 Inches Od 1 Inch Bore

Product Description

The Source1 2813378000 is a single-groove sheave and pulley designed for belt-driven HVAC systems. It fits York and compatible equipment and is built to transfer rotational power from the motor to driven components such as blower fans and air handlers. HVAC technicians rely on sheaves and pulleys to keep airflow systems running at the correct speed and efficiency. Using an OEM-grade replacement like the Source1 2813378000 ensures the part matches the original specifications exactly, reducing the risk of belt slippage, misalignment, or premature wear. This sheave features a 6.75-inch outside diameter and a 1-inch bore size, which are standard dimensions found across a wide range of York residential and light commercial air handling units. Compatible equipment includes units such as the 1FF0114, 1FA0406, and AC042X1221H models, among others. The single-groove design accommodates a standard V-belt drive configuration, which is common in forced-air HVAC systems. Proper sheave-to-belt matching is critical for maintaining the correct blower RPM, which directly affects system airflow, static pressure, and overall heating and cooling performance. A worn or incorrect sheave can cause the belt to run hot, stretch unevenly, or fail early. Replacing it with the correct OEM sheave restores proper drive geometry and extends the life of both the belt and the motor. This part weighs approximately 4.05 pounds and measures roughly 8.05 inches in length, 8 inches in width, and 3.35 inches in height, making it compact enough for standard equipment access panels. HVAC professionals working on York systems will find this a direct drop-in replacement that requires no modification.
