Nordyne 667186R Blower Wheel

The Nordyne 667186R Blower Wheel is a precision-engineered OEM replacement part designed for integration into specific combustion blower assemblies. This 3x1 CCW blower wheel features a 3-inch outside diameter and a 1-inch blade width, specifically balanced to maintain high-static pressure across 1/2-inch motor shafts. Built with galvanized steel blades, this component provides the necessary corrosion resistance for combustion environments while ensuring dynamic stability up to 3,450 RPM. Technicians typically find this unit as a direct drop-in for Nordyne 374500R combustion motors used in 42FR, 48FR, B1, and B2 furnace series. Its counter-clockwise (CCW) rotation is critical for maintaining correct airflow patterns in high-efficiency air handlers and packaged rooftop units from Nortek Global HVAC brands, including Miller, Intertherm, and Gibson. Replacing a damaged wheel with this factory-spec HVAC blower wheel eliminates mechanical vibration and reduces decibel levels during the ignition cycle.

• Direct OEM Compatibility: Ensures seamless fitment on 1/2-inch shafts for Nordyne furnace parts.
• Structural Integrity: Galvanized steel construction prevents premature oxidation in moisture-prone combustion air paths.
• Precision Balancing: Factory-set static balance reduces radial load on motor bearings, extending equipment lifespan.
• Broad Application: Compatible with Intertherm, Miller, and Maytag residential gas furnaces.

• What is the exact shaft size for the 667186R? This wheel is designed for a 1/2-inch press-fit or setscrew mounting on standard combustion motor shafts.
• How do I confirm the rotation? This is a counter-clockwise (CCW) wheel as viewed from the hub/inlet side. Verify your existing motor rotation before installation.
• Does this include the motor scroll? This part number is for the 3x1 blower wheel only; the scroll housing and motor are sold separately.
