The Honda 90501-819-000 Washer (8MM) is a genuine OEM component designed for the H1011 riding mower. As a direct Honda OEM part, this washer is manufactured to the exact dimensions Honda specifies for the H1011, ensuring the correct fit without guesswork. Honda supersedes hardware at serial breaks, so confirm your mower's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Dimensions — manufactured to Honda's exact 8MM specification, so it seats and loads correctly on the H1011 riding mower
- Direct OEM Replacement — sourced directly from Honda, this washer drops in as a like-for-like swap with no rework needed
- Serial Number Matters — Honda updates hardware at serial breaks; cross-reference your H1011 serial number with the fitment table to confirm this is the correct part for your unit
A washer distributes the clamping load of a fastener across a broader surface area, protecting the material beneath and helping the fastener maintain consistent tension over time. On a riding mower like the H1011, hardware that carries the wrong dimensions can allow fasteners to loosen under vibration or cause uneven load distribution on the joint. Replacing a worn or incorrect washer with the correct OEM piece restores the fastener assembly to the condition Honda intended.
