A connecting rod small to suit the UMS 9-115cc — the nine-cylinder 115cc four-stroke radial from UMS.
On this engine the component is the small end of the connecting rod, where it meets the piston pin.
Why this part matters: the small end wears on high-hour engines and shows up as a rattle at idle or a knocking that changes with load.
Fitting note: Check piston pin and circlip condition at the same time.
