The QSM11 CM876 engines, while part of the same family, have specific design requirements that are also met by this housing, ensuring a consistent fit and function across the board.

Component Usage

The 2868954 Rocker Lever Housing is an integral component in the operation of the rocker lever system within engine systems. This housing encases and supports the rocker lever, ensuring its stability and alignment during engine operation.

The rocker lever, which is pivotal in transferring motion from the camshaft to the valves, is securely mounted within the Rocker Lever Housing. This arrangement allows for precise and consistent valve actuation, which is essential for the engine’s performance and efficiency.

Additionally, the Rocker Lever Housing interfaces with other components such as the valve stem and the pushrod. The housing provides a stable platform for the rocker lever to pivot, which in turn transmits the camshaft’s motion to the valve stem via the pushrod. This transmission of motion is vital for the opening and closing of the valves at the correct times, which is fundamental to the engine’s combustion process.

Furthermore, the housing is designed to accommodate adjustments to the valve clearance. This is typically achieved through shims or adjustable components within the housing, allowing for fine-tuning of the valve operation to maintain optimal engine performance.

Conclusion

In summary, the 2868954 Rocker Lever Housing plays a significant role in the coordination and efficiency of the valve train system, ensuring that the rocker lever functions correctly within the engine’s operational parameters. Its compatibility with various Cummins engines, coupled with its robust design and features, makes it a critical component for maintaining engine performance and reliability in heavy-duty applications.
