The Multiquip 0042618000 Lock Washer is a genuine OEM replacement designed for the DCA400SSI ultra-silent diesel generator. As an authentic Multiquip OEM component, it is manufactured to the exact specifications required by the DCA400SSI, ensuring a direct, no-compromise fit wherever lock washers are called out in the assembly. Sourced directly through authorized Multiquip supply channels, this part is the correct choice when restoring fastener integrity during scheduled maintenance or repair work on DCA400SSI units.
Key Features
- Genuine OEM Material Grade — Manufactured to the exact hardness and dimensional tolerances specified for the DCA400SSI, so the washer delivers full locking tension without distorting under load.
- Direct Drop-In Replacement — Matches the original fastener stack-up geometry, seating flush and engaging correctly with the mating bolt or nut without any rework to surrounding hardware.
- Confirmed Fitment for DCA400SSI — Verified for use on the Multiquip DCA400SSI ultra-silent diesel generator series, taking the guesswork out of parts sourcing.
- Vibration Resistance — The locking profile bites into mating surfaces to resist loosening from the continuous engine and alternator vibration inherent in generator operation, maintaining fastener clamp load over time.
- Critical Fastener Safety — Used in applications where fastener loosening can lead to component misalignment or structural failure; using the correct OEM washer maintains the integrity of those connections.
A lock washer is a thin hardened ring fitted beneath a nut or bolt head to prevent the fastener from backing out under vibration or dynamic loads. In a diesel generator like the DCA400SSI, engine vibration is constant, and fasteners throughout the drivetrain, enclosure, and electrical assembly are exposed to that movement every time the unit runs. When a lock washer loses its tension — through wear, over-torquing, or substitution with an undersized part — the fastener can work loose, leading to misalignment, noise, or component damage that is far more costly to address than the washer itself.
