Lennox 18M68 Motor Mount

The Lennox 18M68 Motor Mount is a heavy-duty, belly-band style mounting solution engineered for 48-frame motors in high-performance Lennox air handlers and furnaces. As a genuine OEM Lennox replacement part, this mount ensures precise alignment of the blower motor to minimize mechanical stress and prevent premature shaft or bearing failure. With a 9.875" bolt circle and a robust 3-leg configuration, it provides a secure fit for motors with a 5.625" motor diameter. This HVAC motor mount kit is constructed from high-grade, corrosion-resistant steel designed to withstand the thermal expansion and high-static pressures found in residential and commercial climate control systems. By isolating operational torque, the Lennox 18M68 significantly reduces cabinet hum and structural vibration, maintaining the strict decibel ratings required for quiet system performance. For contractors, the precision-stamped legs and standardized belly-band mounting geometry ensure a seamless drop-in installation, reducing labor time during emergency motor swaps.

• Optimized Motor Alignment: Maintains the critical center-of-gravity for 48-frame motors, preventing imbalanced rotation and excess wear.
• Vibration Dampening: High-tensile steel construction absorbs harmonic resonance, leading to quieter HVAC operation and reduced mechanical fatigue.
• Industrial-Grade Durability: Built with corrosion-resistant materials to ensure structural integrity in high-moisture air handling environments.
• Exact OEM Compatibility: Eliminates the need for field modifications, fitting various Lennox models including the EL180 and 95AF series.

• What motor frame size is compatible with the 18M68? This mount is specifically designed for 48-frame motors with a 5-5/8 inch outer diameter.
• What is the bolt circle measurement for installation? The mount features a 9.875-inch bolt circle, ensuring a standard fit for Lennox blower housings.
• How many legs does this mount utilize? While the bracket provides four points of stability, it is classified as a 3-leg belly-band motor mount for standard furnace configurations.
