The Rocker Lever Housing (3200480) is compatible with both the K19 and K38 engines. These engines are known for their robust design and efficiency, often used in heavy-duty applications. The housing plays a crucial role in these engines by providing a secure mounting point for the rocker levers, which are essential for the valve train operation.

K50 Engine

Similarly, the K50 engine also utilizes the Rocker Lever Housing (3200480). This engine is part of the Cummins lineup that is designed for high-performance and durability. The housing ensures that the rocker levers are properly aligned and supported, which is vital for the smooth operation of the engine’s valve train.

Grouping of Engines

The compatibility of the Rocker Lever Housing (3200480) with the K19, K38, and K50 engines indicates that these engines share a common design philosophy in their valve train mechanisms. This commonality allows for easier maintenance and repair, as the same part can be used across multiple engine models.

By ensuring that the Rocker Lever Housing fits these engines, Cummins maintains a high standard of interchangeability and reliability in their engine components.

Role of 3200480 in Engine Systems

This Cummins part is an integral component in the orchestration of various engine systems, ensuring efficient and reliable performance. It interfaces directly with the camshaft, facilitating the transfer of motion to the valve train. This motion is essential for the precise opening and closing of the engine’s valves, which in turn regulates the intake of air and fuel and the expulsion of exhaust gases.

In conjunction with the intake manifold, the Rocker Lever Housing plays a part in optimizing the airflow into the combustion chambers. Its design and placement contribute to the overall efficiency of the air induction system, impacting the engine’s performance and power output.

The housing is also a key element in the lifting arrangement of the valve train. It supports the rocker arms, which are responsible for amplifying the camshaft’s motion to operate the valves. The integrity and alignment of the Rocker Lever Housing are therefore vital for the consistent and reliable operation of the valve train.

Furthermore, the Rocker Lever Housing is often part of a comprehensive lifting bracket system. This system ensures that the rocker arms are securely held in place and correctly aligned with the camshaft and valves. The housing’s role in this system is to provide a stable and durable platform for the rocker arms, contributing to the longevity and performance of the engine.

In high-performance engine setups, the Rocker Lever Housing may be upgraded or modified as part of performance parts to enhance the engine’s capabilities. Such modifications can include changes to the housing’s material, shape, or internal features to better accommodate higher stresses and more aggressive camshaft profiles.

Additionally, in engines equipped with an aftercooler, the Rocker Lever Housing must be designed to withstand the potentially higher temperatures and pressures that may result from the aftercooling process. This ensures that the housing maintains its structural integrity and functional reliability under these demanding conditions.

Conclusion

In summary, the 3200480 Rocker Lever Housing is a fundamental component that interacts with various engine systems to ensure the smooth and efficient operation of the valve train, contributing to the engine’s overall performance and durability.
