UMS 7-360cc SENSOR LOCK SCREW ( X 10 QTY / Pack)

This is the sensor lock screw for the UMS 7-360cc engine, the seven-cylinder 360cc four-stroke radial from UMS.

The part itself is the sensor locking screws that hold the pickup in position.

Why it is replaced: a screw that backs out lets the sensor move and the timing drift, so these are replaced at service. Supplied as a pack of 10, which is how these small parts are normally bought — you rarely need just one.

Fitting note: Use the correct torque and check the air gap afterwards.
