Valve rocker arm Delta, Alpha, 2 pcs — a valve rocker arm for Alpha and Delta mopeds. The rocker arms transfer motion from the camshaft lobes to the valves and open them at the right moment.
Replace them if you hear a metallic knock in the cylinder head, the working surfaces show wear and scoring, or the valve clearances cannot be adjusted. Rocker arms are usually replaced in pairs.
