Source1 2806564700 Variable Sheave Pulley 1 Groove 4.15 Inches Od 5/8 Inches Bore

Product Description

The Source1 2806564700 is a variable sheave pulley designed for use in commercial and residential HVAC systems. It features a single groove design with an outer diameter of 4.15 inches and a bore size of 5/8 inches. This sheave is a direct OEM replacement part, engineered to meet the original equipment specifications set by York and its affiliated brands.

A sheave, also called a pulley, is a critical mechanical component in belt-driven HVAC systems. It transmits rotational power from the motor to the blower or fan assembly. The variable design of this sheave allows technicians to fine-tune the speed of driven components by adjusting the effective pitch diameter. This gives HVAC professionals precise control over airflow and torque delivery without replacing the entire drive assembly. Proper sheave sizing and alignment directly affect system efficiency, belt life, and overall unit performance.

This part fits several York, Coleman, and Luxaire units including the KBBU-F060A, YCJD60S41S1, and BRCQ0481BD, among others. Using genuine OEM sheaves and pulleys protects your warranty coverage and ensures compatibility with factory-spec V-belts. Aftermarket substitutes can cause belt slippage, premature wear, and reduced airflow, all of which lead to callbacks and increased labor costs. Stocking this sheave on your service vehicle or in your supply room reduces downtime during rooftop and air handler repairs.

HVAC technicians working on belt-drive air handlers, package units, and commercial rooftop systems will find this part essential for blower drive maintenance, seasonal tune-ups, and full drive assembly replacements. It measures 5 inches in length, 5 inches in width, and 3 inches in height, making it compact and easy to handle in tight mechanical compartments.
