Camshaft chain roller, large gear, Delta, Alpha — a timing chain roller for Alpha and Delta mopeds. The rollers guide the camshaft drive chain and reduce its vibration and wear.
Time to replace it if chain noise is heard from the engine, the roller turns with binding, or it has developed play. Replace the part on a cooled engine and a clean assembly so that dirt does not get inside.
