Push Rod
Cummins®

The Cummins 4006170 Push Rod is a component designed for use in heavy-duty truck engines. It plays a role in the engine’s valve train system by facilitating the transfer of motion from the camshaft to the valves. This ensures that the valves open and close at the correct times, which is necessary for the engine’s operation and performance.

Basic Concepts of Push Rods

Push rods are mechanical components used in overhead valve (OHV) engines to transmit motion from the camshaft to the valves. They are typically long, slender rods that connect the camshaft’s lobes to the rocker arms, which in turn operate the valves. The push rod’s role is to convert the rotational motion of the camshaft into linear motion that actuates the valves, allowing for the intake and exhaust processes within the engine ¹.

Purpose of the Cummins 4006170 Push Rod

This Cummins part is specifically engineered to function within the valve train of Cummins engines. It transmits motion from the camshaft to the valves via the rocker arms. This transmission ensures that the valves open and close in synchronization with the engine’s operation, which is necessary for efficient combustion and overall engine performance.

Role of Part 4006170 Push Rod in Engine Systems

The 4006170 Push Rod is an integral component in the operation of several engine systems, particularly in the interaction between the camshaft and the valve train. This push rod facilitates the transfer of motion from the camshaft to the rocker arm, which in turn actuates the valve.

In an overhead valve (OHV) engine, the camshaft is typically located in the engine block. As the camshaft lobes rotate, they push against the push rod, which then extends upward. The push rod’s extension directly influences the rocker arm, causing it to pivot. This pivoting action is transferred to the valve, either opening or closing it as needed to allow air and fuel into the combustion chamber or to expel exhaust gases.

The precision and reliability of the 4006170 Push Rod are essential for maintaining the correct valve timing. Any deviation in the push rod’s performance can lead to inefficiencies in the engine’s operation, affecting overall performance and fuel economy.

Conclusion

In summary, the 4006170 Push Rod plays a significant role in ensuring that the camshaft’s motion is accurately transmitted to the rocker arm, which subsequently controls the valve’s operation. This component’s function is vital for the synchronized and efficient operation of the engine’s valve train.
