Multiquip B2163100004 Coupling Disk - OEM Replacement Part for Super Silent Generators

The coupling disk is a critical power transmission component that connects the diesel engine to the generator head in Multiquip WhisperWatt super silent generator systems. This flexible coupling component absorbs vibration and compensates for minor misalignment between the engine and generator shafts while transmitting rotational power at 1,800 rpm operating speed. Regular inspection of the coupling disk is essential for maintaining smooth, quiet operation and preventing damage to both the engine and generator assemblies.

In WhisperWatt series generators, the coupling disk operates continuously during power generation, subject to significant mechanical stress and thermal cycling. Signs of wear include unusual vibration, noise during operation, or difficulty maintaining rated output. The coupling disk should be inspected during major service intervals and replaced if cracks, excessive wear, or deterioration of the flexible elements are observed.

This coupling disk is designed for DCA-45USI2 series applications and is compatible with the following Multiquip generator models:

• DCA70SSIU4F
• DCA70SSJU4F
• MQP56
