Cummins®

The Cummins 4067301 Plain Hose is a component designed for use in commercial truck systems. It serves a specific function within the truck’s fluid transfer systems, ensuring the efficient and reliable movement of fluids necessary for the operation of various truck systems.

Basic Concepts of Plain Hoses

Plain hoses are flexible tubes used in fluid transfer systems to convey liquids or gases from one point to another. They are characterized by their simplicity, lacking reinforcements such as wire spirals or textile braids found in other hose types. This simplicity allows for flexibility and ease of installation, making them suitable for a wide range of applications. Plain hoses are typically used in systems where the pressure and temperature conditions are within certain limits, and where the hose is not subjected to significant mechanical stress ¹.

Purpose of the Cummins 4067301 Plain Hose

The Cummins 4067301 Plain Hose plays a role in the fluid transfer systems of commercial trucks by transporting fluids between components. It is integral to systems such as the cooling system, where it may carry coolant to and from the engine, or in hydraulic systems for transferring hydraulic fluid. The hose ensures that fluids are delivered efficiently and under the necessary conditions to maintain system performance ².

Key Features

The Cummins 4067301 Plain Hose is constructed from materials chosen for their durability and resistance to the fluids they transport. Its design includes features that enhance its performance, such as smooth inner walls to minimize flow resistance and outer walls that provide the necessary strength and flexibility. The hose’s construction allows it to withstand the operational pressures and temperatures of commercial truck systems ³.

Benefits

The Cummins 4067301 Plain Hose offers several advantages, including efficient fluid transfer due to its design, durability under the pressures and temperatures encountered in truck systems, and resistance to environmental factors that could lead to degradation. These attributes contribute to the reliability and longevity of the hose in demanding applications ⁴.

Installation Considerations

When installing the Cummins 4067301 Plain Hose, it is important to ensure compatibility with other system components and to follow manufacturer guidelines. Proper installation involves securing the hose with appropriate fittings, avoiding kinks or sharp bends that could restrict flow or damage the hose, and ensuring that all connections are tight to prevent leaks ⁵.

Troubleshooting Common Issues

Common issues with plain hoses include leaks and degradation over time. Troubleshooting steps may involve inspecting the hose for signs of wear or damage, checking connections for tightness, and replacing the hose if it shows signs of failure. Regular inspections can help identify potential issues before they lead to system failures ⁶.

Maintenance Tips

To ensure the longevity and optimal performance of the Cummins 4067301 Plain Hose, regular maintenance is recommended. This includes inspecting the hose for signs of wear, checking for leaks, and ensuring that all connections are secure. Replacement guidelines should be followed to maintain system efficiency and safety ⁷.

With a history spanning over a century, Cummins has established a reputation for quality and innovation in the commercial truck industry. Its product range includes engines, powertrain components, and aftermarket parts, all designed to meet the demanding requirements of commercial applications ⁸.

Role of Part 4067301 Plain Hose in Engine Systems

The Cummins 4067301 Plain Hose is integral to the efficient operation of various engine systems. Its primary function is to facilitate the smooth transfer of fluids and gases between different components, ensuring that the engine operates within optimal parameters.

Arrangement

In the arrangement of engine components, the 4067301 Plain Hose plays a significant role in connecting various parts. It ensures that the pathways for fluid and gas flow are maintained without leaks or restrictions. This is particularly important in high-pressure systems where any disruption can lead to inefficiencies or damage ⁹.

Crankcase Breather

The crankcase breather system relies on the 4067301 Plain Hose to vent gases that accumulate within the crankcase. These gases, which include unburnt fuel and combustion byproducts, need to be expelled to prevent pressure build-up. The hose ensures that these gases are directed to a safe location, often back into the intake system, where they can be re-burnt, thus reducing emissions and improving engine performance ¹⁰.

Plumbing

In the context of engine plumbing, the 4067301 Plain Hose is used to connect various fluid systems, such as coolant and oil circuits. It provides a reliable conduit that withstands the temperature and pressure variations within these systems. Proper plumbing is essential for maintaining the thermal management of the engine, ensuring that critical components do not overheat ¹¹.

Aftercooler Water

For engines equipped with an aftercooler, the 4067301 Plain Hose is used to route water through the aftercooler system. The aftercooler is designed to reduce the temperature of compressed air before it enters the combustion chamber. The hose ensures that water flows efficiently through the aftercooler, enhancing the cooling process and contributing to more efficient combustion and reduced emissions ¹².

Conclusion

The Cummins 4067301 Plain Hose is a vital component in the fluid transfer systems of commercial trucks and engines. Its design and construction ensure efficient and reliable fluid transfer, contributing to the overall performance and longevity of the systems it serves. Regular maintenance and proper installation are key to maximizing the benefits of this Cummins part.
