The Honda 90410-SD3-660 Plain Washer (8mm) is a genuine OEM component designed for EP2500 generators and EU3000 inverter generators. Sourced directly from Honda, this washer matches the original specification for the machines it serves, ensuring the correct fit without guesswork. Honda supersedes parts at serial-number breaks, so confirm your unit's serial number against the fitment table before ordering to be sure part number 90410-SD3-660 is the right listing for your machine.
Key Features
- Genuine OEM Part — manufactured by Honda to the same specification as the washer installed at the factory, so dimensions and tolerances are exactly what the assembly calls for.
- Exact-Fit Replacement — designed as a direct drop-in for EP2500 generators and EU3000 inverter generators, with no trimming or adjustment needed.
- Serial Number Matters — Honda updates parts at production breaks, so always match your machine's serial number to the fitment table to confirm part number 90410-SD3-660 applies to your specific unit.
A plain washer distributes the clamping load of a fastener across a wider surface area, preventing the bolt head or nut from pulling through or marring the material beneath it. In a generator or inverter generator, washers like this one appear throughout the assembly wherever consistent clamping force needs to be spread evenly. Using the correct OEM washer ensures the fastener assembly performs as intended; an undersized or incorrect washer can allow fasteners to loosen over time under the vibration a running generator produces.
