Nordyne 667374R Blower Wheel

The Nordyne 667374R Blower Wheel is a precision-engineered 11x8 CW convex blower wheel designed for high-static pressure applications in Intertherm, Miller, and Nordyne furnace systems. This centrifugal blower fan features a convex hub configuration and clockwise rotation (determined by viewing from the hub/motor side), ensuring optimal airflow through the evaporator coil and heat exchanger. As the direct factory replacement for the legacy Nordyne 667374, it addresses common vibration issues caused by unbalanced or aging wheels. Utilizing a double-inlet design with galvanized steel construction, this wheel maintains structural integrity under high RPMs, preventing blade deformation and ensuring consistent HVAC blower wheel replacement performance in residential and light commercial mobile home furnaces. Technical precision in the 1/2-inch bore alignment ensures a secure fit on the motor shaft, reducing bearing wear and extending the operational life of the blower motor assembly.

• Direct OEM Replacement: Seamlessly replaces 667374 models without requiring housing modifications.
• Optimized Airflow: The 11-inch diameter and 8-inch width provide the exact CFM output required for specific Nordyne and Miller furnace footprints.
• Convex Hub Design: Properly aligns the weight distribution across the motor shaft to minimize shaft oscillation and noise.
• Durable Construction: Galvanized steel blades resist corrosion and maintain pitch during high-demand heating and cooling cycles.

Frequently Asked Questions

How do I confirm the rotation of the Nordyne 667374R?
This wheel is rated for clockwise (CW) rotation. To verify, view the wheel from the hub side; the blades are designed to pull air into the center and throw it outward in a clockwise direction.

Will this blower wheel solve vibration noises in my furnace?
If your current wheel has accumulated debris, lost a balance clip, or has bent fins, replacing it with the 667374R will restore balanced rotation and eliminate structural vibration.

Is this compatible with 1/2-inch motor shafts?
Yes, this wheel is designed with a standard hub bore to fit 1/2-inch shafts commonly found on Nordyne blower motors.
