York S1-028-07222-000 Fixed Sheave

When you are servicing York HVAC systems, maintaining proper blower speed and belt alignment depends on the integrity of the drive components. This OEM York S1-028-07222-000 Fixed Sheave is a single-groove drive pulley engineered for specific air handler and furnace blower assemblies. Featuring a 1-inch bore, this cast-iron fixed pitch sheave ensures a consistent RPM ratio, preventing the performance drift often seen with worn or substandard aftermarket pulleys. Professionals know that even slight variations in sheave diameter or groove wear can lead to V-belt slippage, overheating, and premature motor bearing failure.

Designed for durability in high-cycle commercial and residential applications, this blower pulley provides a secure fit on the motor or blower shaft. Proper installation using a calibrated straight-edge for pulley alignment is critical to eliminate vibration and audible resonance in the ductwork. By utilizing this genuine York replacement part, technicians ensure the factory-set static pressure and airflow CFM are maintained, protecting the system from high-limit trips or evaporator coil icing. This sheave is optimized for 4L, A, 5L, or B series belts, delivering a positive drive grip for efficient power transmission.

• OEM Precision: Genuine York replacement part ensures exact dimensional compatibility with original equipment specifications.
• Durable Construction: Heavy-duty cast iron resists groove wear and deformation under high-torque startup loads.
• Consistent Output: The fixed sheave design eliminates the risk of variable pitch adjustments shifting during operation.
• Quiet Operation: Precision-balanced machining reduces rotational vibration and extends the lifecycle of blower motor bearings.

• What belt profiles are compatible with this sheave? This single-groove sheave is typically compatible with standard 4L or A-section V-belts, though always verify the specific belt width to ensure proper seating in the groove.
• Does this sheave include a set screw? Most York blower pulleys utilize a standard set screw to lock onto the shaft flat, preventing high-speed slippage.
• How do I know if my current sheave needs replacement? Inspect the inner walls of the groove; if they appear "U-shaped" or polished rather than straight, the drive pulley is worn and will cause the belt to bottom out and squeal.
