Cummins®

The Cummins 4096490 Rocker Lever is a critical component in commercial truck engines, designed to facilitate the operation of the valve train by transferring motion from the camshaft to the valves. This part ensures the efficient and reliable operation of the engine, contributing to the overall performance and durability of the truck.

Basic Concepts of Rocker Levers

A rocker lever is a mechanical component that amplifies or changes the direction of a force applied to it. In an engine, the rocker lever converts the rotational motion of the camshaft into linear motion to open and close the valves. This mechanism allows for precise control over the timing and duration of valve events, which are essential for engine efficiency and power output ¹.

Role of the 4096490 Rocker Lever in Truck Operation

The 4096490 Rocker Lever interacts with the camshaft and pushrods to actuate the valves, ensuring they open and close at the correct times in the engine cycle. This interaction is vital for maintaining the engine’s performance and efficiency by allowing for the intake of air and fuel and the exhaust of combustion gases ².

Key Features of the 4096490 Rocker Lever

Constructed from high-strength materials, the 4096490 Rocker Lever is designed to withstand the high stresses and temperatures within the engine environment.
