Lennox 86G17 Bracket

The Lennox 86G17 Motor Mount Bracket is a critical OEM replacement part designed for securing 3-leg blower motors within furnace and air handling units. This torsion flex adapter kit is specifically engineered to replace older or failed motor mounting brackets, ensuring the high-speed blower motor remains stable and correctly aligned within the housing. Precision alignment is essential for reducing fan noise and mechanical vibration, which can lead to premature component failure if left unaddressed. The 86G17 bracket is constructed from heavy-duty steel to provide a rigid 5.6-inch diameter mounting base, making it a rugged solution for high-duty cycle HVAC residential and commercial systems.

This technician-grade kit is functionally identical to the Lennox 86G1701 and often serves as a direct upgrade for legacy parts such as 78C77, 78C76, and 78C7701. It is commonly utilized in Lennox G12 series furnaces and handles motors with adjustable flexibility from 5 to 5-1/2 inches. For professionals, the 86G17 motor adapter is the standard choice to restore factory-spec airflow efficiency and prevent the displacement issues typically found with generic aftermarket universal mounts.
