UMS 5-210cc CAM PIN GUIDE ASSLY ( X 2 QTY / Pack)

Replacement cam pin guide assly for the UMS 5-210cc, the five-cylinder 210cc four-stroke radial from UMS.

Function: it is the cam pin guide assembly, which locates the cam follower in the crankcase.

The reason this ends up on an order: a worn guide lets the follower move out of line, which shows up as uneven valve timing and noise. Supplied as a pack of 2, which is how these small parts are normally bought — you rarely need just one.

Fitting note: Check the follower for scoring when renewing the guide.
