York S1-028-13379-000 Sheave

The York S1-028-13379-000 is an OEM 1-groove fixed sheave engineered for precise power transmission in commercial and residential HVAC blower assemblies. This 1 inch bore sheave is designed to meet exact tolerances, ensuring minimal vibration and reduced shaft wear during high-static operation. Built from durable cast iron or machined steel to prevent belt slippage, it is compatible with standard A-section or 4L V-belts commonly found in York, Luxaire, and Coleman air handlers. For technicians performing HVAC blower motor maintenance, this fixed-pitch pulley provides a reliable alternative to adjustable sheaves when a constant RPM is required for system balance. This component is a direct replacement part, ensuring proper alignment with the motor shaft to prevent premature bearing failure. When replacing a York blower pulley, verify the keyway dimensions to maintain a secure mechanical connection and optimize the airflow performance of the drive package.

• Precision Machined 1" Bore: Ensures a tight fit on the blower or motor shaft to eliminate wobbling and mechanical noise.
• OEM Compatibility: Engineered specifically for York S1-028-13379-000 specifications, guaranteeing alignment with existing drive belts.
• Enhanced Durability: Constructed from heavy-duty materials to withstand the high-torque demands of industrial air moving applications.
• Fixed Pitch Performance: Eliminates the risk of setting drift common in adjustable pulleys, maintaining consistent CFM output.
• Corrosion Resistance: Finished to resist oxidation in high-humidity environments typical of rooftop units and indoor air handlers.

Is this sheave compatible with 3L or 5L belts?
This 1-groove fixed sheave is optimized for 4L or A-section belts. Using thinner or thicker belts may lead to improper seating and accelerated belt wear.

Does this part include the set screw?
Typically, York replacement sheaves include the necessary locking set screw to secure the pulley to the 1-inch shaft keyway.

What is the outside diameter of the S1-028-13379-000?
This specific model is designed for fixed-ratio drive systems; always verify the OD against your York technical data sheet to maintain original factory fan speeds.
