The Honda 90506-777-003 Special Washer (6MM) is a genuine OEM component designed for FR650 and FR750 tillers. As a direct Honda OEM part, it is built to the same specification as the original and is an exact replacement for the piece it was designed to serve. Honda supersedes parts across serial number breaks, so confirm your tiller's serial number against the fitment table before ordering to ensure part number 90506-777-003 is the correct listing for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this washer matches the original specification the FR650 and FR750 were assembled with, eliminating guesswork on sizing and tolerancing.
- Correct 6MM Sizing — the (6MM) designation is part of the part identity; verify it matches the washer your tiller requires before purchasing.
- Serial Number Matters — Honda updates part numbers at serial breaks, so cross-check your tiller's serial number against the compatibility table to confirm this is the right listing for your machine.
A special washer is a precisely dimensioned fastening component used to distribute clamping load, maintain correct spacing, or provide a controlled bearing surface at a specific location within the tiller's assembly. Unlike a standard flat washer, a "special" designation indicates that this washer carries a non-standard dimension, profile, or feature specified by Honda for a particular application. When the correct washer is missing, worn, or substituted with an incorrect size, fastener clamping can become uneven, components may shift under load, and premature wear or loosening can follow — making an exact OEM match the straightforward choice for a lasting repair.
