Introduction

The Cummins 3067830 Push Rod is a critical component in heavy-duty truck engines, facilitating the transfer of motion from the camshaft to the valve train. This ensures the engine’s performance and efficiency are maintained ¹.

Basic Concepts of Push Rods

Push rods are essential in overhead valve (OHV) engines, transmitting motion from the camshaft in the engine block to the rocker arms in the cylinder head. This mechanism enables the precise opening and closing of engine valves, crucial for the intake and exhaust processes within the combustion cycle ².

Purpose of the Cummins 3067830 Push Rod

This Cummins part is engineered for the valve train system of compatible engines, ensuring valves open and close in synchronization with engine operation. This precise timing is vital for maintaining engine efficiency and performance ³.

Key Features

The 3067830 is constructed from high-quality materials, ensuring durability and reliability under heavy-duty conditions. It features a smooth surface finish to reduce friction and precise dimensions for accurate valve actuation.

Benefits

Using this part in an engine setup can lead to improved engine efficiency due to precise valve timing, enhanced reliability under heavy-duty conditions, and increased longevity of valve train components thanks to its robust construction.

Installation and Compatibility

Proper installation of this part is crucial for optimal engine performance. It should be installed according to the manufacturer’s guidelines, including specific torque settings and alignment procedures. Compatibility with certain engine models and configurations should be verified to ensure proper fit and function.

The Push Rod 3067830 is designed to fit seamlessly within several Cummins engine models, ensuring the smooth functioning of the valve train system.

L10 CELECT

This part is crucial for maintaining correct valve clearance and ensuring valves open and close at the correct times, which is essential for the engine’s performance and longevity.

M11 CELECT and M11 CELECT PLUS

Both engines are equipped with the Push Rod 3067830, playing a pivotal role by providing necessary support and movement for the valves. The M11 CELECT PLUS, with its advanced features, relies on this push rod to maintain optimal engine efficiency and reliability.

M11 MECHANICAL

This engine also utilizes the Push Rod 3067830, essential for the mechanical operation of the valves, ensuring they function correctly under various operating conditions. The robustness of the Push Rod 3067830 makes it a reliable choice for this engine model.

Role in Engine Systems

The 3067830 is an essential component in the operation of various engine systems, particularly in overhead valve (OHV) engines. It facilitates the transfer of motion from the camshaft to the valve train, ensuring precise and efficient valve operation.

Interaction with the Lever and Rocker

• Lever Mechanism: The Push Rod interacts directly with the lever mechanism within the engine. As the camshaft rotates, it actuates the push rod, which in turn moves the lever. This lever is typically part of the rocker arm assembly, which amplifies the motion to open and close the valves.
• Rocker Arm Assembly: The Push Rod’s primary function is to transmit the motion from the camshaft to the rocker arm. The rocker arm then uses this motion to open and close the engine’s valves. The Push Rod ensures that the motion is consistent and reliable, allowing for optimal engine performance.

Detailed Component Interaction

• Camshaft to Push Rod: When the camshaft lobe rises, it pushes against the Push Rod. This linear motion is critical for the subsequent components in the valve train.
• Push Rod to Rocker Arm: The Push Rod extends to the rocker arm, where it imparts motion. The rocker arm, in turn, leverages this motion to open the valve against the spring pressure.
• Valve Operation: The rocker arm, actuated by the Push Rod, ensures that the valves open and close at the precise moments required for the engine’s combustion cycle. This timing is vital for maintaining engine efficiency and performance.

Conclusion

The Cummins 3067830 Push Rod is a versatile and essential component that ensures the proper functioning of the valve train system across multiple Cummins engine models. Its compatibility with the L10 CELECT, M11 CELECT, M11 CELECT PLUS, and M11 MECHANICAL engines underscores its importance in maintaining engine performance and reliability.
