Source1 2816451000 Variable Single Groove Sheave Pulley 5/8 Inches Bore

Product Description

The SOURCE1 2816451000 is a variable, single groove sheave and pulley designed for belt-driven HVAC systems. It fits a range of commercial and residential heating and cooling units, including popular models such as BRCQ0481BD, AW15N3DQ2S1AAA31A2, and BRCQ0301BE. This OEM replacement part is built to the same standards as the original component, helping technicians restore equipment performance without compromise.

Sheaves and pulleys are critical components in belt-driven HVAC systems. The sheave connects to the motor shaft or blower shaft and transfers rotational power through a belt to move air across the coil. When a sheave wears out, cracks, or loses its grip on the belt, airflow drops and the system loses efficiency. A variable sheave allows for speed adjustment, giving HVAC technicians the ability to fine-tune blower performance to match system requirements and improve static pressure balance.

The 2816451000 features a 5/8 inches bore, making it compatible with standard motor and blower shaft sizes commonly found in commercial rooftop units and air handlers. The single groove design accepts a single V-belt drive configuration. At approximately 3.45 inches in length, 3.4 inches in width, and 2.15 inches in height, this is a compact but solid component. It weighs 2 pounds, indicating durable cast construction that resists vibration and wear over long run cycles.

HVAC service professionals, mechanical contractors, and facilities maintenance teams rely on OEM-spec sheaves to maintain airflow ratings, motor amperage within nameplate limits, and overall system reliability. Using the correct replacement sheave also reduces belt wear and extends the service interval between drive component inspections.
