The Honda 90581-GB5-610 Plain Washer (6MM) is a genuine OEM component designed for GXV160 vertical shaft engines, H6522 compact tractors, and HRC216 lawn mowers. As a direct Honda OEM part, it is manufactured to the exact dimensions Honda specifies for these applications. Confirm your machine's serial number against the fitment table before ordering, as Honda updates part numbers at production breaks and the correct washer for your unit depends on that serial range. This genuine replacement ensures the proper load distribution and clamping retention that the original assembly was engineered around.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this washer matches the exact diameter, thickness, and bore of the original part it replaces, maintaining correct fastener clamping across the assembly
- Broad Fitment — listed for GXV160 vertical shaft engines, H6522 compact tractors, and HRC216 lawn mowers; verify your serial number against the compatibility table to confirm the correct application
- Direct Replacement — drops into place with no modification, restoring the original hardware stack as Honda assembled it at the factory
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 damaging softer material beneath it. In assemblies like those found on GXV160 engines, H6522 compact tractors, and HRC216 mowers, using the correctly sized washer keeps fastener preload consistent and the joint secure over time. When a washer is missing, undersized, or deformed, the fastener can loosen under vibration or the mating surface can become damaged, making future service more difficult.
