A cylinder with sleeve to suit the UMS 9-115cc — the nine-cylinder 115cc four-stroke radial from UMS.
On this engine the component is the cylinder barrel with its pressed-in sleeve, forming the bore the piston runs in.
Why this part matters: the sleeve is the wear surface; a scored or oval bore is the reason to replace the cylinder rather than just the rings.
Fitting note: Measure the bore at several heights before condemning it, and oil the bore on assembly.
