The Honda 90652-VF9-A01 is a genuine OEM Inner Circlip (28MM) designed for UMK422 and UMK431 trimmers. As a direct Honda OEM component, this circlip is manufactured to the exact dimensions required for proper retention and function in these trimmers. Honda supersedes parts at serial breaks, so confirm your trimmer's serial number against the fitment table before ordering to ensure part number 90652-VF9-A01 is the correct match for your unit.
Key Features
- Genuine OEM Retention — sourced directly from Honda, this circlip meets the exact dimensional specification required to hold rotating or sliding components securely in place within UMK422 and UMK431 trimmers
- Exact 28MM Inner Diameter — the (28MM) designation identifies this specific variant; verify it matches your application before ordering, as circlips of different diameters are not interchangeable
- Trimmer Fitment — listed for the UMK422 and UMK431 trimmers; check your serial number against the fitment table to confirm this is the correct circlip for your serial range
- Restore Proper Component Retention — a worn, deformed, or missing inner circlip allows components to shift axially, leading to erratic operation or mechanical damage; replacing it restores correct assembly
An inner circlip is a precision retaining ring that seats into a groove machined into a bore or housing, preventing a shaft, pin, or bearing from moving axially out of position. In a trimmer such as the UMK422 and UMK431, these small clips hold drivetrain and shaft components in their correct positions so the unit runs smoothly and power is transmitted without unwanted play. When a circlip fails — through fatigue, improper installation, or corrosion — the retained component can shift or separate, causing vibration, loss of drive, or further mechanical damage to surrounding parts.
