Lennox 31G67 Wheel
The Lennox 31G67 Blower Wheel is a precision-engineered OEM replacement part designed for high-performance air delivery in residential furnaces and light commercial air handlers. This centrifugal blower wheel features a 12-inch diameter and 9-inch width, specifically balanced to maintain system integrity and reduce mechanical stress on the blower motor. Constructed from heavy-duty galvanized steel, it provides superior resistance to corrosion and physical deformation under high static pressure transitions. The 1/2-inch bore includes a secure sleeve-style hub for direct-drive configurations, ensuring a positive lock on the motor shaft with its integrated set screw.
For technicians performing a furnace blower repair, the 31G67 is a critical component for restoring original manufacturer airflow specifications. Its clockwise (CW) rotation is calibrated for specific Lennox and allied brand blower assemblies, including Armstrong and Ducane models (cross-referencing parts like 31G6701, 71L38, and R20298004). By replacing a fouled or unbalanced wheel with this genuine Lennox furnace part, you mitigate vibration-induced noise and prevent premature bearing failure within the drive assembly. This wheel is optimized for direct drive blower assemblies where consistent CFM and quiet operation are non-negotiable for system efficiency.
Key Benefits- Optimized Airflow: Precision-curved blades increase aerodynamic efficiency and maintain proper static pressure.
- Structural Durability: Galvanized steel construction resists moisture and oxidation in demanding HVAC environments.
- Vibration Dampening: Factory-level balancing reduces operational noise and protects motor shaft bearings.
- Universal Compatibility: Direct-fit replacement for numerous Lennox, Armstrong, and Ducane furnace models.
How do I determine the correct rotation for the 31G67?
The 31G67 is designed for clockwise (CW) rotation. When inspecting the wheel from the hub side, ensure your motor rotation matches to avoid efficiency loss or motor overheating.
Will this wheel fit a 1/2-inch motor shaft?
Yes, this wheel features a standard 1/2-inch bore with a built-in set screw designed to secure directly to 1/2-inch motor shafts used in Lennox direct-drive systems.
What are the signs that my blower wheel needs replacement?
Excessive vibration, "thumping" noises during startup, or visible dust and debris buildup on the fins that cannot be cleaned indicate that the wheel is out of balance and requires replacement.
