UMS 9-99cc SPACER ( X 4 QTY / PACK)

Replacement spacer for the UMS 9-99cc, the nine-cylinder 99cc four-stroke radial from UMS.

Function: it is a spacer that sets the position or end-float of a rotating or bolted part.

The reason this ends up on an order: getting the stack height right matters, so a spacer is replaced when the original is crushed, worn or the wrong thickness is needed. Supplied as a pack of 4, which is how these small parts are normally bought — you rarely need just one.

Fitting note: Measure the assembled end-float rather than assuming the original spacer is correct.
