ROD ASSEMBLY, PUSH
Navistar International®

Push Rod Assembly is an internal engine component that is responsible for transmitting the motion of the camshaft to the rocker arms. It is a long, slender rod that is located inside the engine block and runs parallel to the cylinder head. The push rod assembly is made up of several individual push rods that are connected together by a series of ball and socket joints. As the camshaft rotates, it pushes against the push rods, which in turn push against the rocker arms, causing them to move up and down. This movement opens and closes the engine's valves, allowing air and fuel to enter and exhaust gases to exit the combustion chamber. The part number 1873916C2 is a specific push rod assembly used in commercial trucks.
