4N-1108: Rocker Arm Shaft

Description: The rocker arm shaft assembly is a mechanical component used in internal combustion engines to transmit motion from the camshaft to the valves. It consists of a shaft, which is mounted to the cylinder head and has rocker arms attached to it. The rocker arms pivot on the shaft and transfer the motion of the camshaft to the valves. The assembly is responsible for opening and closing the engine's intake and exhaust valves, which allow air and fuel to enter the engine and exhaust gases to exit. Proper timing and alignment of the rocker arm shaft assembly are critical for the engine to run efficiently and smoothly. Attributes: • hardened steel, while the rocker arms and brackets can be made of cast iron or other metals. • manufactured to a precise specification and is built for durability, reliability, and productivity. Applications: The shaft in the engine mounts valves and helps to transmit the up-and-down movement of the piston. It is widely used in Cat D400, D40, D44B, D550B - ARTICULATED DUMP TRUCK, PR-450, PM 565, PR 1000 - COLD PLANNER, 3412C, PM 3412, CG137-12, G342, XQG400 - GENERATOR ENGINE, 990, 992D, 980C, 988B - WHEEL - TYPE LOADER, 651E, 657E, 621B, 621E - WHEEL TRACTOR SCRAPPER and 826C, 826G, 836, 825C - EARTHMOVING COMPACTOR
