The Honda 90402-344-820 Washer (8X22) is a genuine OEM part designed for a wide range of Honda tillers and water pumps, including the F400, F401, F501, FC600, FG400, FG500, FR500, FR600, FR650, FR700, FR750, WB20, and WB30. As a direct Honda OEM component, this washer is manufactured to the exact specifications called out in Honda's own parts catalog. Because Honda supersedes hardware across serial number breaks, confirm your machine's serial number against the fitment table before ordering to ensure this is the correct listing for your unit.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this washer matches the original specification for proper load distribution and fit in the applications it covers.
- Broad Fitment Coverage — listed for Honda tillers including the F400, F401, F501, FC600, FG400, FG500, FR500, FR600, FR650, FR700, and FR750, as well as WB20 and WB30 water pumps.
- Verify by Serial Number — Honda updates hardware at production breaks, so always match your machine's serial number to the fitment table to confirm part number 90402-344-820 is the right washer for your specific unit.
A washer of this size serves as a load-spreading and clamping interface between a fastener and the surface it secures, distributing the clamp load evenly and helping maintain consistent tension in the assembled joint. Using the correct OEM washer — with the right inner diameter, outer diameter, and thickness — ensures the fastener assembly behaves as Honda designed. Substituting an incorrect washer can result in uneven clamping, fastener loosening over time, or damage to the mating surfaces on the equipment it powers.
