Key Features
- Genuine OEM Construction — Manufactured to the exact material grade and dimensional tolerance specified by Multiquip, ensuring the washer seats and loads correctly within the assembly.
- Direct Drop-In Fitment — Matches the original hole pattern, thickness, and outer diameter for straightforward installation without reworking surrounding hardware.
- Broad Model Coverage — Compatible with DAC7000SS, DAC7000SSW, DAC7000SSA ultra-silent generators and DLW300ES and DLW400ES series welders under the Multiquip portfolio.
- Fastener Integrity — A correctly rated washer distributes clamping load evenly across the mating surface, preventing fastener pull-through, surface deformation, and loosening under vibration during extended generator or welder operation.
- Verified OEM Part Number — Part number 6641655170 is the genuine Multiquip reference; cross-check this number against your machine's parts manual before ordering.
A washer serves as a load-distributing interface between a fastener — bolt, nut, or screw — and the surface it clamps against. By spreading clamping force over a larger area, it prevents the fastener from pulling through or damaging softer mating surfaces and helps maintain consistent torque retention even under the continuous vibration common to diesel generators and welders. When a washer is missing, undersized, or worn flat, fasteners can work loose during operation, leading to misaligned components and potential mechanical failure in the assembly they secure.
