The Honda 94510-30000 Outer Circlip (30MM) is a genuine OEM retaining clip designed for a wide range of Honda generators, tillers, trimmers, and horizontal shaft engines, including the E300, EM400, EM5000, ER400, FR650, FR750, FRC800, GX35, and UMC435. As a factory-sourced component, this circlip is made to Honda's exact specifications, ensuring the correct fit and retention performance for each application it covers. Confirm the serial number on your machine against the fitment table before ordering, as Honda issues part supersessions at specific serial breaks.
Key Features
- Genuine OEM Retention — sourced directly from Honda, this circlip meets the exact dimensional and retention specifications required to secure shafts and bores correctly across all listed applications
- 30MM Outer Diameter — the (30MM) designation identifies this variant; verify this size matches your unit before ordering, particularly where multiple circlip sizes appear in the same catalogue
- Broad Fitment — listed for Honda E300, EM400, EM5000, ER400, FR650, FR750, FRC800, GX35, and UMC435 equipment; check your serial number against the fitment table to confirm the correct circlip for your serial range
- Proper Retention Function — a correctly fitted circlip keeps the relevant shaft or pin positively located; a worn, sprung, or incorrectly sized clip allows axial movement that leads to accelerated wear on adjacent components
An outer circlip is a sprung retaining ring that seats in an external groove machined into a shaft or pin, preventing the shaft from moving axially out of its bore or housing. It works by springing open to accept the groove, then contracting to lock into place, providing a positive mechanical stop with no fasteners. When a circlip is deformed, incorrectly sized, or missing entirely, the shaft or pin it retains can walk out of position, causing noise, play, and damage to the components it supports. Replacing a fatigued or damaged circlip with the correct Honda OEM part restores proper retention and protects the surrounding assembly.
