Cummins Overview

Cummins Inc. is a renowned manufacturer with a long-standing reputation in the automotive industry. The company is committed to producing high-quality components that enhance the performance and reliability of engines. Cummins’ dedication to innovation and quality is reflected in their wide range of automotive parts, including the 163002 Rocker Lever Spacer.

Compatibility with Cummins Engines

The 163002 Rocker Lever Spacer is compatible with various Cummins engines, including the G855, G855 CM558, GTA855 CM558 (CM2358) G101, and N14 G engines. This part is designed to maintain the correct clearance between the rocker levers and the camshaft, ensuring smooth and efficient engine performance.

Role of the 163002 Rocker Lever Spacer in Engine Systems

In the orchestration of engine components, the 163002 Rocker Lever Spacer assumes a significant role by ensuring precise alignment and spacing between various elements. This spacer is positioned between the Rocker Lever and the Rocker Arm Housing, facilitating the correct operation of the rocker mechanism.

When installed, the 163002 maintains the appropriate distance between the Rocker Lever and the Rocker Housing. This spacing is essential for the uninhibited movement of the Rocker Lever as it responds to the camshaft’s lobes. The spacer prevents any undue contact that could lead to friction or binding, which might otherwise impair the lever’s function.

Moreover, the spacer contributes to the stability of the Rocker Arm Housing. By providing a consistent and reliable gap, it allows the housing to support the rocker arm without the risk of deformation or excessive wear. This, in turn, ensures that the rocker arm can transmit motion to the valve train with the necessary precision.

The Base Parts of the engine also benefit from the presence of the 163002. By ensuring that the rocker mechanism operates within its designed parameters, the spacer helps to maintain the integrity of the base components. This is particularly important in high-performance engines where the tolerances are tight, and any deviation can lead to a cascade of issues.

Conclusion

The 163002 Rocker Lever Spacer is an integral component that supports the dynamic relationship between the Rocker Lever, Rocker Arm Housing, and Rocker Housing. Its role in preserving the correct spacing and alignment is fundamental to the efficient and reliable operation of the engine’s valve train.
