Multiquip 9091605080 Plain Washer

The Multiquip 9091605080 Plain Washer is a genuine OEM component designed for DCA-series ultra-silent diesel generators, including the DCA25SSI, DCA25SSIU, DCA25SSAI, DCA25SSI2, DCA25SSIU-GEER, DCA60SSAI, and DCA60SSI2. As a Genuine OEM part, it is sourced directly through Multiquip to ensure correct dimensions and material grade for each specific application. Buying the exact OEM washer eliminates the guesswork of matching thread pitch, outer diameter, and thickness — keeping your generator assembly torqued and seated correctly from the start. DHS Equipment stocks this part to support contractors and rental fleets that depend on continuous generator uptime.

Key Features

• OEM-Grade Material and Dimensional Accuracy — Manufactured to the precise thickness, inner diameter, and outer diameter specified for DCA-series generator assemblies, ensuring correct load distribution across fastened joints.
• Drop-In Hardware Fit — Matches the original hardware profile exactly, seating flush against mating surfaces without shimming or reworking surrounding fasteners.
• Broad DCA-Series Compatibility — Confirmed fitment across DCA25SSI, DCA25SSIU, DCA25SSAI, DCA25SSI2, DCA25SSIU-GEER, DCA60SSAI, and DCA60SSI2 ultra-silent generator models.
• Protects Fastener Integrity — Distributes clamping load evenly across the mating surface, preventing bolt heads and nuts from embedding into softer substrates and loosening under vibration.
• Genuine Multiquip OEM Part — Sourced through the official Multiquip parts network, carrying part number 9091605080 for straightforward cross-referencing during service and inspection.

A plain washer serves as a load-spreading interface between a fastener — such as a bolt head or nut — and the surface it clamps against. By distributing the clamping force over a wider area, it prevents the fastener from pulling through or damaging the material beneath it and helps maintain consistent torque retention over time. In a diesel generator like the DCA-series, where panels, brackets, and internal components are subject to continuous vibration during operation, using the correct washer is essential; an undersized or incorrect washer can allow fasteners to work loose, leading to rattles, misalignment, or structural fatigue at connection points.
