Role of Part 3928832 in Engine Systems

The Push Rod Cover Gasket 3928832 is an essential component in the sealing and maintenance of various engine systems. It is specifically designed to ensure the integrity of the push rod cover, which is a critical part of the valve train system in overhead valve (OHV) engines.

Integration with Engine Components

1. Cam Follower Cover: The Push Rod Cover Gasket interfaces directly with the cam follower cover. It ensures a tight seal between the cover and the engine block, preventing oil leaks and maintaining the proper lubrication of moving parts within the valve train.
2. Breather System: In conjunction with the crankcase breather kit, the gasket helps manage crankcase ventilation. It allows pressure to be released from the crankcase while preventing oil from escaping, thus contributing to a cleaner and more efficient engine environment.
3. Crankcase: The gasket is positioned between the push rod cover and the crankcase. This placement is vital for maintaining the structural integrity of the crankcase, ensuring that no oil or contaminants enter the combustion chamber.
4. Cylinder Head: Although the Push Rod Cover Gasket does not directly contact the cylinder head, its role in sealing the push rod cover indirectly supports the overall sealing strategy of the engine, which includes the cylinder head gasket.
5. Complete Engine Gasket Kit and Full Engine Gasket Set: When included in a complete engine gasket kit or a full engine gasket set, the Push Rod Cover Gasket plays a part in the comprehensive sealing solution for the engine. It ensures that all critical areas are sealed, contributing to the engine’s overall performance and longevity.
6. Lower Engine Gasket Kit and Set: In a lower engine gasket kit or set, the Push Rod Cover Gasket is one of the many gaskets designed to seal the lower portion of the engine. This includes the crankcase, oil pan, and other lower engine components, ensuring a leak-free environment.
7. Overhaul Kit and Rebuild Kit: During engine overhauls or rebuilds, the Push Rod Cover Gasket is a necessary component. It ensures that the push rod cover is properly sealed, which is essential for the successful completion of the overhaul or rebuild process.
8. Subset and LWR ENG GSK (TAL): In subsets of gasket kits or specific lower engine gasket tal (TAL) configurations, the Push Rod Cover Gasket is included to address the unique sealing requirements of the push rod cover in these applications.

Summary of Component Interaction

The Push Rod Cover Gasket 3928832 interacts with a variety of engine components to ensure the engine operates efficiently and without leaks. Its role in sealing the push rod cover is integral to the maintenance of the valve train system, crankcase ventilation, and overall engine integrity.

Conclusion

The Push Rod Cover Gasket 3928832 by Cummins is a vital component for maintaining the efficiency and integrity of heavy-duty truck engines. Its proper installation and maintenance are crucial for preventing oil leaks and ensuring the engine’s longevity and performance.
