Multiquip C3163600003 Adapter Coupling DCA-400SSI - OEM Replacement Part

The coupling adapter is a critical connection component in the DCA-400SSI Super Silent generator series, providing the mechanical interface between the engine and generator head. This precision-engineered adapter ensures proper torque transfer and alignment between the Isuzu BQ-6WG1X diesel engine and the revolving field synchronous generator, which operates at 1,800 rpm to produce 60 Hz power output. Proper coupling integrity is essential for maintaining generator performance across the full load range from prime output (320 kW / 400 kVA) to standby output (336 kW / 420 kVA).

This adapter is specifically designed for the Whisperwatt™ Series DCA-400SSI models, which utilize an open-delta excitation system for reliable voltage regulation. Any coupling wear, misalignment, or damage can result in vibration, reduced power quality, or catastrophic failure of the generator assembly.

Compatible with the following Multiquip generator models:

• DCA400SSI4F
• DCA400SSI4F3B
• DCA400SSI4F3PD
