Introduction

The Rocker Lever Shaft 3679418, manufactured by Cummins, is a significant component in the context of heavy-duty truck engines, contributing to their performance and reliability.

Basic Concepts of Rocker Lever Shafts

A Rocker Lever Shaft is a mechanical component in the valve train system of an engine. It transfers motion from the camshaft to the valves, enabling them to open and close at precise intervals, which is essential for the intake and exhaust processes within the engine ¹.

Purpose of the 3679418 Rocker Lever Shaft

This Cummins part facilitates the interaction between the camshaft and the valves. As the camshaft rotates, it actuates the rocker lever shaft, which in turn opens and closes the valves. This precise timing is vital for the engine’s combustion process, affecting both performance and fuel efficiency ².
