The Honda 90503-777-003 Special Washer (8MM) is a genuine OEM component designed for FR650, FR750, and FRC800 tillers. As a factory-sourced part, it is manufactured to the same standards as the original hardware installed at the time of production, ensuring it seats and functions exactly as intended. This washer is the correct specification for these Honda tillers — confirm your machine's serial number against the fitment table before ordering to make sure this is the right part for your unit.
Key Features
- Correct 8MM Sizing — the (8MM) designation is the key spec to match; verify your tiller's original hardware before ordering
- Tiller Fitment — listed for the FR650, FR750, and FRC800 tillers; check your serial number against the fitment table to confirm applicability
- Serial Number Awareness — Honda updates hardware specs at production breaks, so verifying your machine's serial number ensures you receive the correct variant
A special washer of this type serves as a precisely dimensioned bearing surface within the tiller's assembly, distributing clamping load evenly across the mating components it contacts. The "special" designation indicates it differs from a standard flat washer in one or more dimensions — such as outer diameter, inner bore, or thickness — making the correct part number critical. Using an incorrect washer can result in improper load distribution, fastener loosening over time, or damage to surrounding components during tiller operation.
