York s1-02812363700 Sheave Pulley 5.45in Od Single Groove

Product Description

The YORK s1-02812363700 is an OEM sheave and pulley designed for belt-driven blower and fan assemblies in YORK heating and cooling equipment. With a 5.45-inch outside diameter and a 1-inch bore, this single-groove pulley transfers rotational power from the motor shaft to the belt, driving air-moving components at the correct speed and load. Weighing 2.305 pounds, it is built to OEM dimensional and balance specifications, which helps maintain proper belt tension and reduces premature wear on belts and bearings. Licensed HVAC technicians and sheet metal mechanics install this part during scheduled maintenance or component replacement service calls.

This sheave is used in residential and light commercial YORK forced-air systems where belt-drive blower configurations are employed. It is a direct OEM replacement intended to restore original performance in equipment that has experienced pulley wear, groove damage, or bore damage. Compatible units include the 1LD0407, 1HA0459, and 1HA0451 model families, among others listed in the equipment compatibility documentation for this part number.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out electrical power to the unit before removing the belt or accessing the blower assembly. Inspect the matched belt for wear and replace it if cracking, glazing, or fraying is present. Verify bore alignment and shaft concentricity after seating the pulley to prevent vibration and premature belt failure.
