The Multiquip 1603294040 Flat Washer is a genuine OEM component designed for DA7000SSA2 and DLW400ES series equipment. As a direct OEM replacement, this washer is manufactured to the exact dimensions and material specification required by Multiquip for proper load distribution and fastener retention across these machines. Confirmed fitment includes the DA7000SSA2, DA7000SSA2GH, and DLW400ES / ESA / ESA1 models. Sourcing the correct OEM part ensures the hardware stack-up performs as engineered without shimming or improvisation.
Key Features
- OEM-Spec Material and Dimensioning — Manufactured to Multiquip's exact thickness, outer diameter, and hardness rating, ensuring the washer bears load and distributes clamping force as intended for these generator and welder platforms.
- Drop-In Hardware Replacement — Seats directly against mating fastener hardware with no reworking of the surrounding assembly, maintaining the original bolt pattern and torque integrity.
- Confirmed Fitment — Compatible with DA7000SSA2, DA7000SSA2GH diesel-powered generators and DLW400ES, DLW400ESA, and DLW400ESA1 welder models.
- Fastener Integrity Protection — A correctly sized flat washer prevents fastener heads and nuts from pulling through or deforming mounting surfaces — a worn or undersized washer can allow hardware to work loose under vibration, leading to component misalignment.
- Genuine Multiquip OEM Part — Supplied as original equipment, this washer carries the Multiquip part number 1603294040 and meets the same standard as the hardware installed at the factory.
A flat washer serves as a load-spreading interface between a fastener — bolt head or nut — and the surface it clamps against. By distributing clamping force over a wider area, the washer protects the mating surface from deformation and keeps the fastener seated securely under operational vibration. In generator and welder applications where engine vibration is constant, using the correct OEM washer with the right outer diameter and thickness is essential to keeping critical hardware torqued and properly retained over time. A missing or incorrect washer can allow fasteners to loosen progressively, which may lead to component movement, surface damage, or fastener failure.
