Daikin-McQuay GCF1876K Bearing & Mounting Plate

Upgrade your air handling assembly with the Daikin-McQuay GCF1876K Bearing & Mounting Plate, a critical OEM component designed for high-performance HVAC systems. This 1/2" bearing and mounting plate kit serves as the direct replacement for LC611 and LC611A, ensuring a seamless fit without the need for field modifications. Engineered for the rigors of commercial blower motor assemblies, the GCF1876K features a precision-machined 1/2 inch bore bearing housed in a heavy-duty steel plate to minimize vibration and shaft deflection.

For service technicians managing McQuay, AAF, or HermanNelson equipment, this HVAC blower shaft bearing provides the structural stability required for high-static pressure environments. Utilizing genuine Daikin replacement parts like the GCF1876K ensures proper alignment of the power transmission components, extending the operational life of the blower wheel and motor. Whether performing a routine HVAC bearing replacement or a complete fan overhaul, this kit delivers the specialized tolerances necessary for OEM fan deck repairs.

Key Benefits

• Precision Alignment: Centered 1/2" bearing bore prevents premature shaft wear and reduces mechanical noise.
• OEM Compatibility: Specifically engineered for Daikin McQuay air handlers and PTAC units as a drop-in LC611 replacement.
• Heavy-Duty Construction: Reinforced mounting plate resists torsion and provides a stable foundation for the rotating assembly.
• Vibration Dampening: High-grade internal races ensure smooth rotation, protecting the blower motor assembly from harmonic fatigue.

Common Questions

Is the GCF1876K compatible with older LC611 units?
Yes, the Daikin-McQuay GCF1876K is the definitive manufacturer-superseded part for both LC611 and LC611A, maintaining the exact mounting footprint and 1/2" bore specifications.

Does this kit include the mounting hardware?
This part consists of the integrated bearing and mounting plate. Technicians should inspect existing hardware for fatigue; however, the plate is pre-drilled to match standard OEM blower housing specifications.

What are the signs that my HVAC bearing needs replacement?
Audible "squealing," increased amperage draw on the motor, or visible shaft play are indicators that the bearing and mounting plate have failed and require immediate replacement to prevent total system failure.
