The Honda 90603-ZE1-003 Circlip (10.2MM) is a genuine OEM retaining clip designed for GX140, GX160, and GX200 horizontal shaft engines. As a Honda OEM component, this circlip is manufactured to the exact dimensions Honda specifies, ensuring the correct fit and retention force for the application it was engineered to serve. This part is listed for the GX140, GX160, and GX200 engines — confirm your engine's serial number against the fitment table before ordering, as Honda updates part numbers at serial breaks. When a circlip fails or goes missing, the shaft or pin it retains can shift, leading to accelerated wear or mechanical failure in the engine.
Key Features
- Genuine OEM Retention — sourced directly from Honda, this circlip meets the exact 10.2MM dimension specified for proper seating and holding force in the groove it occupies
- Direct OEM Replacement — installs into the existing groove without modification.
- GX-Series Fitment — listed for GX140, GX160, and GX200 horizontal shaft engines; cross-reference your serial number against the fitment table to confirm the correct application
- Critical Retention Function — a circlip in poor condition or the wrong size will not seat fully in its groove, allowing the retained component to walk or disengage under load
A circlip is a thin, open-ring fastener that snaps into a machined groove on a shaft or inside a bore, locking a component axially in place without threads or adhesive. In Honda's GX-series horizontal shaft engines, circlips are used at key internal retention points to keep pins, shafts, or rotating components from migrating out of position during operation. When a circlip is worn, sprung, or missing, the component it retains is free to shift, which can result in rapid internal wear or a more serious mechanical failure.
