Source1 2812363700 Sheave Pulley 5.45 Inches Od 1 Inch Bore Single Groove

Product Description

The SOURCE1 2812363700 is a single-groove sheave and pulley designed for belt-driven HVAC equipment. It features a 5.45-inch outside diameter and a 1-inch bore size, making it a direct-fit replacement for a range of York heating and cooling units including popular models 1LD0407, 1HA0459, and 1HA0451. This OEM-grade component is engineered to deliver consistent rotational power transfer between the motor shaft and belt-driven blower or fan assemblies. In belt-drive HVAC systems, the sheave and pulley work together to transmit torque from the motor to the blower wheel. A correctly sized sheave ensures the blower spins at the right RPM for proper airflow and system efficiency. Using a genuine OEM replacement like the SOURCE1 2812363700 helps maintain the original equipment performance specifications and avoids the fit and finish issues that can come with aftermarket alternatives. HVAC technicians rely on OEM pulleys and sheaves to keep air handlers, rooftop units, and furnace blowers running at peak performance. This pulley is built to the same tolerances as the original factory part, reducing vibration, belt wear, and premature failure. The single-groove design is standard for single-belt drive configurations found across a wide range of residential and light commercial HVAC systems. With a weight of approximately 2.305 pounds and compact dimensions of 5.6 inches in length and width and 1.55 inches in height, this sheave is easy to handle and install during routine maintenance or emergency service calls. Whether you are replacing a worn sheave on a scheduled PM or responding to a no-airflow service call, the SOURCE1 2812363700 is the reliable, code-compliant choice for restoring proper belt-drive operation.
