Nordyne 668928R Arm
The Nordyne 668928R Motor Mount Arm is a critical OEM replacement part designed to secure and stabilize the blower motor within Nordyne, Intertherm, and Miller furnace assemblies. For technicians managing high-static pressure systems, maintaining precise motor alignment is essential to prevent bearing failure and premature belt or direct-drive fatigue. This 11-inch motor mount arm features a heavy-duty steel construction engineered to withstand the rotational torque and thermal cycles typical of residential and light commercial air handlers. By utilizing a genuine Nortek part, you ensure that the geometry matches the original factory specifications, which is vital for minimizing HVAC vibration noise and optimizing airflow efficiency. The integrated motor mount grommet housing (grommet sold separately or included based on specific kit variations) provides the necessary isolation to prevent harmonic resonance from transferring through the chassis. When performing a furnace motor repair, replacing worn or bent arms with the 668928R ensures a return to factory-balanced operation and reliable service life.
Key Benefits:
- Ensures precise blower motor alignment to reduce radial load on motor bearings and extend component lifespan.
- Constructed from high-tensile steel for maximum rigidity during high-RPM start-up cycles and operation.
- Engineered as a direct OEM HVAC replacement part for seamless mechanical fitment in Nordyne-branded equipment.
- Optimizes noise attenuation by providing a stable platform for vibration isolation components.
- Simplifies motor bracket installation with pre-engineered mounting points that match standard furnace housing bolt patterns.
Common Questions:
What are the signs that a motor mount arm needs replacement?
Technicians should look for visible stress fractures, excessive motor play, or humming sounds caused by metal-to-metal contact when the isolation grommets fail and the arm loses structural integrity.
Is the Nordyne 668928R compatible with all direct-drive blowers?
This arm is specifically designed for Nordyne and Intertherm furnaces; contractors should verify the 11-inch length and bolt-hole spacing against the existing blower housing before installation.
Does this arm include the required mounting grommets?
The 668928R is the structural arm; while some configurations include a pre-installed grommet, it is recommended to inspect and replace the rubber isolators concurrently to ensure total vibration reduction.
