The Honda 90401-371-000 Washer (12.2X33X3.2) is a genuine OEM washer designed for the HP400 power carrier. As a factory-sourced component, this washer is manufactured to Honda's exact dimensional specifications, ensuring the correct load distribution and clamping surface for the fastener assembly it belongs to. Buyers should confirm the part number 90401-371-000 against their HP400 serial number using Honda's fitment table before ordering.
Key Features
- Genuine OEM Dimensions — sourced directly from Honda, this washer meets the exact 12.2 x 33 x 3.2 mm dimensional spec, ensuring proper load-bearing surface and clamping performance at the fastener point.
- Direct OEM Replacement — this part installs in place of the original with no modification, maintaining the integrity of the assembly on the HP400 power carrier.
- Verify by Serial Number — Honda updates parts at production breaks, so confirming your HP400's serial number against the fitment table is the best way to ensure this washer is correct for your unit.
A washer at this size serves to distribute the clamping load of a fastener across a wider surface area, preventing damage to the mating component and maintaining consistent tension in the assembly. On the HP400 power carrier, where reliable fastener retention is essential to safe operation under load, using the correctly dimensioned OEM washer helps preserve the integrity of the assembly over time. A washer that is undersized, oversized, or worn thin can allow fasteners to work loose or damage the surrounding material.
