The Multiquip 8171020004 is a genuine OEM Insulator Washer designed for DCA-series ultra-silent and super-silent diesel generator sets, including the DCA220SSK, DCA400SPK, DCA500SSK, DCA600SSK, DCA600SSV, DCA600SSV4F3B, DCA600SSV4F3PB, DCA800SSK, and DCA800SSK2. As a genuine OEM component, this washer is manufactured to the exact tolerances required for proper electrical isolation within the generator assembly. DHS Equipment stocks this part to keep your DCA generator running safely and within spec. Verify your model code against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Electrical Isolation: — Engineered to the exact dielectric and dimensional specification required for safe current isolation within DCA-series generator assemblies.
- Drop-In Compatibility: — Matches the original mounting configuration, seating correctly against the generator's hardware without rework or shimming.
- Broad DCA Generator Fitment: — Confirmed for DCA220SSK, DCA400SPK, DCA500SSK, DCA600SSK, DCA600SSV, DCA600SSV4F3B, DCA600SSV4F3PB, DCA800SSK, DCA800SSK2, and GEER-configured variants.
- Prevents Electrical Fault Risk: — A correctly seated insulator washer maintains the separation between conductive components, preventing shorts, grounding faults, and premature hardware failure.
- Electrical Safety Critical: — Insulator washers in generator assemblies are safety-rated components; using the correct OEM part ensures the isolation barrier performs as the generator was designed to require.
An insulator washer is a non-conductive fastener component positioned between electrically live hardware and adjacent metal surfaces inside the generator assembly. Its job is to prevent unwanted electrical contact — stopping current from traveling through mounting bolts or brackets where it should not. When an insulator washer cracks, deforms, or is substituted with a standard metal washer, the isolation barrier is lost, which can result in grounding faults, component damage, or electrical hazard conditions. Replacing a worn or damaged insulator washer with the correct OEM part restores the intended isolation and keeps the generator operating within its designed electrical parameters.
