The Multiquip 66416 Washer is a genuine OEM washer designed for DAC7000SS, DAC7000SSW, DAC7000SSA, DLW300ES, and DLW400ES series equipment. Sourced directly from Multiquip, this washer delivers the exact fit and material spec required to maintain proper fastener load distribution across these generator and welder platforms. Keeping this small but critical component in good condition helps preserve the structural integrity and service life of the assemblies it supports.
Key Features
- Genuine OEM Material Spec — Manufactured to Multiquip's exact hardness and dimensional tolerances, ensuring correct load-bearing performance at every fastener point.
- Direct Drop-In Fit — Engineered to seat flush against mating surfaces on DAC7000SS, DAC7000SSW, and DAC7000SSA ultra-silent generators and DLW300ES and DLW400ES diesel welders without rework or shimming.
- Broad Series Coverage — A single part number covers both the diesel generator and diesel welder product families, simplifying parts sourcing across your fleet.
- Prevents Fastener Loosening and Surface Damage — A correctly spec'd washer distributes clamp load evenly, reducing the risk of fastener pull-through, galling, or vibration-induced loosening in high-cycle operating environments.
- Verified Multiquip OEM Part — Part number 66416 is the exact reference used by Multiquip, eliminating guesswork when ordering and ensuring you receive the right component the first time.
A washer serves as the load-spreading interface between a fastener — such as a bolt or nut — and the surface it clamps against. By distributing clamping force over a wider area, it protects softer or thinner materials from deformation and helps maintain consistent tension in bolted joints. In generator and welder applications where vibration is constant, a worn, undersized, or missing washer can lead to loosened fasteners, misaligned components, and accelerated wear on surrounding hardware — making this small part an important factor in long-term assembly stability.
