Multiquip M1164400203 Coupling Ring Denyo - OEM Replacement Part for Super Silent Generators

The coupling ring provides critical mechanical connection between the engine and generator assembly in Multiquip WhisperWatt™ Super Silent generators. This precision-engineered component ensures proper torque transfer and alignment between the Isuzu 4LE2X diesel engine and the revolving field generator, operating at 1,800 rpm. Failed or worn coupling rings can cause vibration, misalignment, power delivery issues, or complete loss of generator function.

This Denyo coupling ring is designed specifically for high-output industrial generators ranging from 36 kW to 45 kW standby capacity. These units feature turbocharged, charge air-cooled engines with EGR and DOC systems, requiring durable drivetrain components that can handle continuous operation under load. The coupling ring maintains critical concentricity between the engine flywheel and generator rotor during both prime and standby power applications.

Compatible with the following Multiquip generator models:

• DCA36SPXU4F (36 kW Prime / 40 kW Standby)
• DCA45SSIU4F (45 kW)
• DCA45SSIU4FC8 (45 kW)
