Rocker Lever Support (Part 4900413) Compatibility with Cummins Engines

The Rocker Lever Support part 4900413, manufactured by Cummins, is designed to be compatible with a range of Cummins engines. This part is crucial for maintaining the proper function of the rocker levers, which are integral to the engine’s valve train operation.

A1400 and A1700 Engines

The Rocker Lever Support part 4900413 is specifically engineered to fit the A1400 and A1700 engines. These engines are part of Cummins’ smaller engine series, often used in compact machinery and light-duty applications. The design of the part ensures it can handle the specific load and operational conditions of these engines.

A2000 and A2300 Engines

Similarly, the Rocker Lever Support part 4900413 is also compatible with the A2000 and A2300 engines. These engines are part of Cummins’ medium-duty engine series, typically used in a variety of applications from medium trucks to industrial equipment. The part’s robust design ensures it can withstand the higher demands and operational stresses of these engines.

Grouping for Compatibility

The compatibility of the Rocker Lever Support part 4900413 across the A1400, A1700, A2000, and A2300 engines is due to the standardized design and engineering principles employed by Cummins. This standardization allows for easier maintenance and repair, as the same part can be used across multiple engine models, reducing inventory needs and simplifying the supply chain.

Role of Part 4900413 Rocker Lever Support in Engine Systems

The part 4900413 Rocker Lever Support is an integral component in the operation of engine systems, particularly in the valve train mechanism. This support is designed to provide a stable mounting point for the rocker lever, which is essential for the efficient transfer of motion from the camshaft to the valves.

In the valve train, the rocker lever is responsible for amplifying the motion of the camshaft lobe. It does this by converting the rotational motion of the camshaft into the linear motion required to open and close the engine’s valves. The rocker lever support ensures that this conversion is performed with precision and minimal deflection, which is vital for maintaining valve timing and engine performance.

The support is typically mounted on the cylinder head, where it interfaces with other components such as the camshaft, pushrods (in pushrod engines), and the rocker lever itself. In overhead camshaft (OHC) engines, the rocker lever support may be part of the rocker arm assembly, directly interacting with the camshaft lobes.

In engines with hydraulic lifters, the rocker lever support must accommodate the lifter’s operation, which maintains zero valve clearance by adjusting to thermal expansion and wear. The support’s design must allow for the lifter’s movement while ensuring that the rocker lever remains securely in place.

For engines utilizing solid lifters, the rocker lever support must be robust enough to handle the direct transfer of motion from the lifter to the rocker lever without any intervening hydraulic components. This requires a design that can withstand higher stresses and maintain alignment under varying engine loads.

In summary, the part 4900413 Rocker Lever Support plays a significant role in the valve train’s functionality by providing a stable and precise mounting point for the rocker lever. Its design and integration with other engine components are essential for the reliable operation of the valve train and, by extension, the engine’s overall performance.

Conclusion

The 4900413 Rocker Lever Support is a critical component in the operation of Cummins engines, ensuring the efficient and reliable functioning of the valve train system. Its design, compatibility across various engine models, and the benefits it offers in terms of engine performance and longevity make it an essential part for maintaining the high standards of Cummins engines.
