Compatibility with Cummins Engines

This Cummins part is designed to fit seamlessly with several of their engine models. This cover is essential for providing access points for maintenance and inspection purposes, ensuring that technicians can easily reach critical areas of the engine.

QSK19 and CM2350 Engines

The QSK19 and CM2350 engines are part of Cummins’ range of industrial and marine engines, known for their robust performance and reliability. The 4967604 is specifically engineered to fit these engines, ensuring that it aligns perfectly with the design specifications of both models. This compatibility allows for easy installation and removal, facilitating routine maintenance and reducing downtime.

K105 Engine

The K105 engine is another model in Cummins’ lineup that benefits from the 4967604. This cover is designed to integrate smoothly with the K105, providing a secure and durable solution for accessing the engine’s internal components. Its precise fit ensures that it does not interfere with other parts of the engine, maintaining the overall integrity and performance of the K105.

Grouping of Engines

While the 4967604 is compatible with the QSK19 and CM2350 engines, it is also designed to fit the K105 engine. These engines, though part of different series, share common design principles that allow for the interchangeability of certain components, including this hand hole cover. This compatibility is crucial for fleets and operators who utilize multiple Cummins engine models, as it simplifies maintenance procedures and inventory management.

Role of Part 4967604 Hand Hole Cover in Engine Systems

The 4967604 is an essential component in the maintenance and operation of various engine systems. It is specifically designed to fit and seal the access points, commonly referred to as hand holes, which are integral to the crankcase breather arrangement.

Integration with Crankcase Breather Arrangement

In the crankcase breather arrangement, the hand hole cover plays a significant role by providing a secure seal over the access points. This seal is vital for maintaining the integrity of the crankcase ventilation system. The crankcase breather arrangement is responsible for releasing pressure build-up within the crankcase, which occurs due to the combustion process.

The hand hole cover ensures that the breather system operates efficiently by preventing external contaminants from entering the crankcase. It also helps in retaining the necessary pressure levels within the system, which is essential for the proper functioning of the engine.

By fitting snugly over the hand holes, the cover allows mechanics to access the interior of the crankcase for inspection or maintenance without compromising the sealed environment. This design facilitates easier and safer maintenance procedures, ensuring that the engine components remain protected and function optimally.

Conclusion

The Cummins 4967604 Hand Hole Cover is a critical component for maintaining and servicing commercial truck engines. Its durable construction, precise fit, and ease of installation make it an invaluable tool for technicians. Regular maintenance and proper installation are key to ensuring the longevity and effectiveness of this part, contributing to the overall reliability and performance of the truck.
