York S1-026-16381-139 Blower Wheel

For service technicians on a call with a failing air handler or furnace, the York S1-026-16381-139 Blower Wheel is a precision-engineered OEM replacement designed to restore designed static pressure. This 10x10 blower wheel features a 1/2-inch bore and is balanced for counter-clockwise (CCW) rotation, ensuring quiet operation and maximum CFM output. Built with a double-inlet design and single-hub convex center plate, this centrifugal blower wheel incorporates 48 steel blades to maintain consistent airflow across the evaporator coil or heat exchanger, preventing high-limit trips or coil freeze-ups. As a genuine HVAC replacement part, it guarantees exact dimensional fitment within the blower housing, eliminating the vibration issues and shaft-seizing common with universal "fit-all" alternatives. When your HVAC blower wheel replacement requires original factory specifications to meet efficiency ratings, this York OEM blower wheel provides the structural integrity and performance required for high-demand residential and commercial applications.

• OEM Precision Fit: Eliminates the need for shaft modifications or housing adjustments often required with generic wheels.
• High-Efficiency Airflow: The 48-blade design is optimized for specific York blower assemblies to maintain HVAC efficiency.
• Structural Durability: Constructed with a convex center plate for enhanced rigidity under high RPMs and heavy static loads.
• Quiet Operation: Factory balanced to minimize mechanical resonance and bearing wear on the blower motor.

What are the symptoms of a bad York blower wheel?
Technicians typically look for excessive vibration, loud "thumping" sounds during motor startup, or reduced airflow at the registers despite a high-speed motor signal. Cracks in the hub or blades often necessitate immediate replacement.

How do I confirm the rotation direction?
Check the rotation from the hub/motor side. This unit is CCW (Counter-Clockwise). Installing a wheel with the wrong rotation will significantly reduce airflow and can cause the motor to overheat.

Can I use a 1/2" bore wheel on a 5/8" motor shaft?
No. The 1/2-inch bore must match the motor shaft diameter exactly. Forcing a fit or using adapters can lead to catastrophic failure of the blower assembly.
