Lennox 71M17 Mounting Arm
The Lennox 71M17 Mounting Arm is a precision-engineered OEM motor mount designed to provide stable structural support for blower motors in high-performance air handlers and furnaces. Measuring approximately 4.718 x 4.156 inches, this heavy-duty blower motor support arm ensures proper alignment and vibration dampening, which is critical for maintaining long-term bearing integrity and system efficiency. Compatible with popular Lennox CB28UH and CB29M series air handlers, the 71M17 acts as a direct replacement for Lennox part LB-101207B, featuring factory-integrated grommets and sleeves for a seamless installation. By securing the motor within the housing, this Lennox motor mounting bracket minimizes mechanical resonance and noise during high-torque startup cycles. For veteran technicians, this genuine HVAC motor mount replacement is the standard for restoring factory-spec motor positioning in residential and light commercial equipment, ensuring the assembly remains rigid under maximum static pressure loads.
Key Benefits:- Precision Alignment: Engineered specifically for Lennox blower motor installation, ensuring the shaft is centered for optimal airflow and reduced amp draw.
- Vibration Mitigation: Includes integrated rubber grommets and sleeves to isolate mechanical noise and prevent structural fatigue in the blower housing.
- Direct OEM Fit: Replaces Lennox 71M17 and LB-101207B, eliminating the need for field modifications or universal brackets that can compromise airflow.
- Durable Construction: Built to withstand commercial-grade thermal variations and high-RPM stress within the air handler unit.
- Can this arm be used with non-Lennox motors? While designed for Lennox OEM replacement parts, compatibility depends on the motor frame size; always verify the 4.718 x 4.156-inch dimensions against the motor housing before mounting.
- Does the 71M17 include the mounting hardware? It typically includes the pre-installed vibration grommet and sleeve, but technicians should retain existing bolts for the motor-to-arm connection.
- Which units is this mounting arm compatible with? It is most commonly found in Lennox air handler units such as the CB28UH-048 and CB29M-65 series.
