York 026-19654-709 Wheel

The York 026-19654-709 Wheel is a high-performance blower component designed for precise integration within York and Johnson Controls air handling assemblies. As a direct York blower wheel replacement, this unit is engineered with an 11-inch diameter and an 8-inch width, adhering to strict OEM tolerancing for optimal static pressure management. For contractors identifying parts via the S1-026-19654-709 reference, it is critical to note this is an HVAC centrifugal blower wheel featuring CW rotation (Clockwise) when viewed from the hub or drive end. The 1/2-inch bore facilitates a secure fit on standard motor shafts, preventing axial slip and minimizing rotational vibration that can lead to premature motor bearing failure. This 11x8 blower wheel CW utilizes a convex hub design to maximize airflow efficiency and maintain consistent CFM delivery across varying duct velocities. Proper installation ensures the blower housing maintains its designed aerodynamic profile, preventing air cavitation and reducing mechanical noise during peak demand cycles.

Key Benefits

• Precision-balanced blades reduce mechanical stress and extend the service life of the blower motor.
• Galvanized steel construction provides durability and resistance to moisture-induced corrosion.
• Consistent fin spacing ensures uniform air distribution across evaporator or condenser coils.
• Direct OEM fitment eliminates the need for field modifications or shaft spacers during installation.

Common Questions

How do I verify the rotation for the York 026-19654-709?
Rotation is determined by looking at the wheel from the hub side. This specific model is a CW (Clockwise) rotation wheel. Confirming the motor's directional output is essential, as reverse rotation will drop system efficiency by up to 70%.

Will this wheel fit a 5/8-inch motor shaft?
No. This wheel is manufactured with a strict 1/2-inch bore. Attempting to bore out the hub or force-fit it will compromise the balance and integrity of the assembly.

Why is static balancing important for this blower wheel?
Because this wheel operates at high RPMs, even a minor imbalance can cause resonant frequencies that damage the mounting brackets and motor internals. This OEM part arrives factory-balanced to meet manufacturer airflow specs.
