Multiquip C3164200004 Coupling Hub Washer

The Multiquip C3164200004 Coupling Hub Washer is a genuine OEM component designed for DCA300SS and DCA400SS series ultra-silent diesel generators. This washer is an exact OEM replacement sourced directly through Multiquip, ensuring correct fitment across a wide range of DCA-series generator models. Compatible units include the DCA300SSC, DCA300SSCU, DCA300SSJU4F, DCA400SSI, DCA400SSK, DCA400SSV, MQP240, and related variants. Keeping this small but critical component in proper condition helps maintain the integrity of the generator coupling assembly and protects surrounding drivetrain hardware.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original specifications, this washer delivers the correct material grade, thickness, and load-bearing surface needed for coupling hub applications in heavy-duty generator sets.
• Drop-In Compatibility — Designed to seat correctly within the coupling hub assembly without rework, aligning with existing hardware on DCA-series generator models.
• Broad DCA-Series Fitment — Confirmed for DCA300SS, DCA300SSJU4F, DCA400SSI, DCA400SSK, DCA400SSV, MQP240, and numerous variant configurations across the Multiquip ultra-silent generator lineup.
• Protects Coupling Alignment — A properly seated coupling hub washer maintains correct axial spacing and load distribution, preventing accelerated wear to the coupling and adjacent components.
• Part of a Dependable OEM Supply Chain — Sold by DHS Equipment as an authorized Multiquip parts distributor, this part is traceable and verified against Multiquip's current parts documentation.

The coupling hub washer serves as a load-distributing interface within the generator's coupling assembly, which connects the engine output shaft to the alternator. By sitting between mating surfaces at the coupling hub, the washer maintains correct axial positioning and ensures even force distribution during operation. When this washer wears, deforms, or goes missing, coupling alignment can shift, leading to vibration, accelerated wear on the coupling itself, and potential damage to both the engine and alternator flanges.
