Cummins®

The 5417353 Rocker Lever, manufactured by Cummins, is a component designed for use in commercial trucks. Cummins, a well-established name in the engine manufacturing industry, produces a range of parts that contribute to the efficiency and reliability of truck engines. This part is integral to the operation of internal combustion engines, playing a significant role in the valve train system ¹.

Basic Concepts of Rocker Levers

A rocker lever is a mechanical component found in the valve train of an engine. Its primary function is to transfer motion from the camshaft to the valves, allowing them to open and close at precise intervals. This transfer of motion is facilitated through a pivot point, which enables the rocker lever to amplify the camshaft’s motion, providing a mechanical advantage. This advantage ensures that the valves open sufficiently to allow the necessary airflow into and out of the engine cylinders ².

Purpose of the 5417353 Rocker Lever

This Cummins part is specifically designed to operate within the valve train system of truck engines manufactured by Cummins. It facilitates the opening and closing of valves in direct response to the movement of the camshaft. By doing so, it ensures that the air-fuel mixture is properly admitted into the cylinders during the intake stroke and that exhaust gases are efficiently expelled during the exhaust stroke. This precise control over valve operation is vital for the engine’s performance and efficiency.

Key Features

The 5417353 is characterized by its robust design and material composition, which are tailored to withstand the demanding conditions within a truck engine. It is constructed from high-quality materials, often featuring heat treatment or specific alloy usage to enhance its durability and performance.
