A circlip rocker arm to suit the UMS 5-250cc — the five-cylinder 250cc four-stroke radial from UMS.
On this engine the component is the rocker arm retaining circlip.
Why this part matters: renewed whenever the rocker gear is disturbed, since a dislodged clip can jam the valve train. Supplied as a pack of 5, which is how these small parts are normally bought — you rarely need just one.
Fitting note: Use a new clip every time; a sprung clip can come off in service.
