The Honda 90508-777-003 Special Washer (5MM) is a genuine OEM component designed for FR650 and FR750 tillers. As a direct Honda OEM part, it is manufactured to the exact dimensions and tolerances specified for these machines, ensuring a proper fit without guesswork. This washer is listed for both the FR650 and FR750 — confirm the part number 90508-777-003 against your tiller's serial number and parts diagram before ordering, as Honda supersedes and updates hardware at production breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this washer matches the original specification for FR650 and FR750 tillers, not an approximation.
- Correct 5MM Sizing — the (5MM) designation identifies this as a specific variant; verify this matches your tiller's parts diagram to ensure the right washer for your application.
- Serial Number Verification Advised — Honda updates hardware at production milestones, so cross-check your machine's serial number against the fitment table before placing your order.
A special washer is a precisely dimensioned fastener component used to distribute load, control spacing, or provide a reliable bearing surface at a specific assembly point within the tiller. Unlike a standard flat washer, a "special" designation in Honda's parts catalogue indicates a geometry, thickness, or profile engineered for a particular location in the machine. When the correct washer is missing or worn, fastener clamping can become uneven, which may cause components to work loose over time and affect the tiller's operation.
