The Honda 90052-ZA0-800 Spring Washer (6mm) is a genuine OEM component designed for Honda EM650, EX5500, and EX650 generators. Sourced directly from Honda, this washer matches the exact dimensions and tension profile specified for these generators. If you are restoring a fastened joint to its original clamping condition, using the correct OEM spring washer ensures the assembly performs as Honda intended. Always cross-check your generator's serial number against the fitment table before ordering, as Honda updates part numbers at production breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Spring Washer (6mm) carries the correct geometry and spring tension for the EM650, EX5500, and EX650 generators it was engineered for.
- Exact Replacement — a direct drop-in under part number 90052-ZA0-800, matching Honda's original specification with no adaptation needed.
- Serial Number Verification Recommended — Honda supersedes hardware at production milestones, so confirm your generator's serial number against the fitment table to ensure this is the correct listing for your unit.
A spring washer is a split or wave-form ring placed beneath a fastener to maintain clamping force in an assembled joint. As vibration and thermal cycling work on a fastened connection over time, a flat washer alone can allow the fastener to loosen; the spring washer's residual tension resists that movement and keeps the joint secure. When a spring washer loses its tension or is omitted, fasteners in the assembly are more likely to back off under the normal operating vibration of the generator.
