Cummins 3046420 Push Rod

The Cummins 3046420 push rod is a critical valve train component designed for Cummins 855 and N14 series heavy-duty diesel engines. It transmits camshaft motion to the rocker arms, actuating both intake and exhaust valves. Manufactured from chromium-molybdenum alloy steel with surface-hardened ball ends, it provides high fatigue resistance and wear resistance under high-stress operating conditions. This part serves as a direct replacement for OEM references AR11780, 217929, and 3012462. It is compatible with non-certified 14-liter N14 engines and various NT855, NTA855, NH855, and Big Cam configurations used in commercial trucks, construction machinery, and industrial power units.
