Lennox 81W81 Mounting Plate

The Lennox 81W81 Mounting Plate is an OEM belt-drive blower motor mounting base engineered to secure high-torque 3 HP motors within commercial and industrial air handling units. This heavy-gauge steel motor mounting plate is a direct replacement for the legacy part number 607388-08, ensuring precise alignment of the HVAC blower assembly. When you are dealing with vibration issues or motor swaps in the field, this plate provides the structural rigidity needed to maintain tension on belt-drive systems, preventing premature wear on sheaves and belts. Designed specifically for Lennox LCA and LHA series rooftop units (including LCA090 and LHA090 models), the Lennox 81W81 features pre-drilled mounting patterns that match factory specifications for a drop-in fit. Integrating this genuine Lennox HVAC part eliminates the need for field modifications, ensuring the blower motor operates within its designed performance curve while dampening operational noise levels.

• Direct OEM Compatibility: Specifically designed for Lennox belt-drive blower motors, ensuring a precise fit with zero modifications.
• Vibration Dampening: Constructed from heavy-duty steel to absorb 3 HP motor torque and reduce noise across the cabinet.
• Structural Integrity: Resists warping under high thermal and mechanical stress, maintaining proper motor-to-fan alignment.
• Versatile Application: Compatible with several popular Lennox models, including LGA120H and LGC150S series.

• Is this mounting plate compatible with 3 HP motors? Yes, the Lennox 81W81 is precision-engineered for 3 HP belt-drive blower applications.
• Will this fit my specific Lennox rooftop unit? This plate is a standard fit for many LCA, LHA, and LGA commercial models. Always verify the part number against your unit's data plate.
• Do I need to replace the mounting hardware? It is recommended to inspect all bolts and vibration isolators for wear when installing a new HP motor mounting base.
