The Multiquip B3163100204 is a genuine OEM Coupling Disk designed for DCA-series super-silent and ultra-silent diesel generators, including the DCA36SPXU4F, DCA40SSKU4F, DCA40SSKU4F2, and DCA45SSIU4F families. As a factory-sourced component, this coupling disk meets the original design requirements for drivetrain alignment and torque transfer in these generator units. It is a direct-fit replacement for the listed DCA models, ensuring compatibility without guesswork. DHS Equipment stocks this part to help you get your generator back on line with confidence.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications, ensuring the coupling disk transmits torque consistently without slippage or premature wear.
- Direct-Fit Replacement — Engineered to align with the existing engine-to-alternator interface on DCA-series units, dropping into place without reworking mounting points.
- Broad DCA-Series Compatibility — Confirmed fitment across DCA36SPXU4F, DCA40SSKU4F, DCA40SSKU4F2, DCA45SSIU4F, and DCA45SSIU4FC8 super-silent generator models.
- Drivetrain Integrity — A correctly seated coupling disk maintains smooth power transfer from the diesel engine to the alternator, preventing vibration, misalignment, and output instability under load.
- Verified Part Number — Order B3163100204 with confidence; this is the exact Multiquip OEM reference for these generator families, eliminating the risk of receiving an incompatible component.
A coupling disk sits between the engine and the alternator, transmitting rotational power while absorbing minor misalignment and torsional shock loads that occur during startup and under fluctuating electrical demand. In diesel generator applications like the DCA-series, the coupling disk protects both the engine crankshaft and the alternator rotor from stress fractures caused by sudden torque spikes. When the disk wears, cracks, or fails, the result is vibration, rough running, and ultimately a loss of stable power output — making timely replacement critical to uninterrupted generator operation.
