Key Features
- Genuine OEM Material Spec — Manufactured to the exact hardness and dimensional tolerances of the original, ensuring consistent seating and clamping force under the cap nut.
- Direct Drop-In Replacement — Matches the original mounting configuration on DCA series generators, allowing straightforward installation without reworking surrounding hardware.
- Broad DCA Series Compatibility — Fits DCA40SSAI, DCA40SSI, DCA45SSIU2, DCA45SSIU2-GEER, DCA45SSIU2-FEMA, DCA60SSAI, and DCA60SSI2 ultra-silent generator models.
- Fastener Integrity — A properly functioning cap nut washer distributes clamping load evenly, preventing fastener loosening from vibration during generator operation.
- Verified Multiquip Part Number — Sold as 9111791050 — cross-reference this number against your service manual or parts diagram before ordering to confirm application.
A cap nut washer sits between a cap nut and the mating surface to distribute the clamping force of the fastener across a wider area. This prevents the nut from pulling through or damaging the surface it bears against, and it helps maintain consistent torque retention even when the machine is subject to vibration during operation — a common condition in generator applications. When a washer is missing, undersized, or deformed, the cap nut can loosen over time, leading to component movement, surface damage, or fastener failure that can escalate into a larger repair.
