DESCRIPTION

The Cummins 4003925 Rocker Lever is a component designed for use in heavy-duty trucks. It serves a specific function within the engine’s operation, contributing to the overall efficiency and performance of the vehicle. Understanding its role and significance is key to appreciating how it integrates into the complex mechanical system of a truck engine.

Basic Concepts of Rocker Levers

A rocker lever, in the context of an engine, is a mechanical component that amplifies the motion of the camshaft to operate the valves. It functions based on the principle of leverage, where a small movement at one end of the lever results in a larger movement at the other end ¹. This mechanism allows for precise control over the opening and closing of engine valves, which is essential for the engine’s combustion process.

Purpose of the 4003925 Rocker Lever

The 4003925 Rocker Lever is specifically designed to interact with other engine components to facilitate efficient engine performance. It plays a role in transferring motion from the camshaft to the valves, ensuring that the valves open and close at the correct times and with the appropriate force. This interaction is vital for maintaining the engine’s timing and efficiency ².

Key Features

The Cummins 4003925 Rocker Lever is engineered with specific design and construction features that enhance its functionality and durability. It is constructed from materials chosen for their strength and resistance to wear, ensuring longevity under the demanding conditions of heavy-duty truck engines.
