The Multiquip 1666255620 Flat Washer is a genuine OEM component designed for DA7000SSA2, DA7000SSA2GH, DAC7000SS, DAC7000SSW, and DAC7000SSA super-silent diesel generators. As a direct OEM replacement, this washer is sourced to the exact specification used in original assembly, ensuring a correct, trouble-free fit across the compatible generator family. Keeping fastened connections properly loaded is critical in generator applications where vibration cycles are continuous, and using the correct OEM hardware eliminates the guesswork of matching thickness, outer diameter, and material grade. DHS Equipment stocks this part ready to ship so you can get your machine back in service without delay.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact material and dimensional specification used in original generator assembly, ensuring correct load distribution across fastened joints.
- Drop-In Installation — Matches the original bore diameter and outer dimensions exactly, so it seats without rework or shimming during reassembly.
- Broad Generator Family Coverage — Confirmed fitment for DA7000SSA2, DA7000SSA2GH, DAC7000SS, DAC7000SSW, and DAC7000SSA super-silent diesel generator models.
- Vibration Resistance — Correct washer geometry maintains consistent clamping force under the sustained vibration loads typical of continuous-duty generator operation, preventing fastener loosening over time.
- Part Number Confidence — Ordering by Multiquip part number 1666255620 confirms you are receiving the correct hardware for your specific generator model, not a generic substitute.
A flat washer distributes the clamping load of a bolt or nut across a wider surface area, preventing fastener heads from pulling through or deforming the material being secured. In generator equipment, washers also help maintain consistent torque retention across components that experience ongoing vibration during operation. When the wrong washer is used — or a worn one is not replaced — fastener joints can loosen prematurely, leading to misalignment, rattling, or component damage over time.
