Key Features

• Genuine OEM Specification: — Manufactured to Multiquip's exact dimensional and material tolerances for the coupling hub, so the washer provides proper load distribution and clamping force at the drive interface.
• Direct-Fit Installation: — Engineered to drop into place within the existing coupling hub assembly on DCA-series generators without modification to surrounding hardware.
• Broad DCA-Series Compatibility: — Fits DCA180, DCA220, and DCA250 Super-Silent and diesel generator variants, including Isuzu, John Deere, Cummins, and Volvo-powered configurations across multiple Tier ratings.
• Protects Coupling Integrity: — A correctly seated hub washer prevents metal-to-metal contact and uneven stress on the coupling, which left unchecked can lead to premature coupling wear or generator shaft damage.
• Verified Part Number: — Sourced directly under OEM part number C1164200004, eliminating guesswork when ordering a replacement for your DCA-series generator.

The coupling hub washer sits within the drive coupling assembly that connects the generator's prime mover — the diesel engine — to the alternator. Its role is to evenly distribute clamping load across the hub faces, keeping alignment stable and preventing slippage or vibration-induced wear at the connection point. When this washer is worn, deformed, or missing, the coupling can develop play that produces vibration, accelerates hub wear, and ultimately compromises the mechanical link between engine and alternator, affecting power output quality and drivetrain longevity.
