Rocker Lever
Cummins®

The Cummins 5484230 Rocker Lever is a critical component in commercial truck engines, designed to enhance engine performance and efficiency. Understanding its function and operation is essential for maintaining and optimizing truck engine performance.

Basic Concepts of Rocker Levers

A rocker lever in mechanical systems amplifies force. In an engine, it transfers motion from the camshaft to the valves, ensuring precise timing for the intake and exhaust of gases necessary for combustion ¹.

Purpose of the 5484230 Rocker Lever

This Cummins part facilitates valve movement in response to camshaft rotation. It interacts with the camshaft through a cam lobe, transferring motion to the valve, either directly or via pushrods in overhead valve engines. This interaction is vital for precise valve timing, which is essential for engine performance ².

Key Features

Constructed from high-quality materials, the 5484230 Rocker Lever ensures durability and reliability under demanding conditions. Its design includes a hardened roller tip for reduced friction and wear, and a robust body to withstand high stresses, contributing to its performance and longevity ³.
