Cummins®

The Lubricating Oil Filter Head, identified by Cummins Part #3918290, is a critical component in the engine system. Manufactured by Cummins, a well-established name in the commercial truck industry, this part ensures the efficient operation of the oil filtration system within the engine.

Function and Operation

The Lubricating Oil Filter Head facilitates the flow of oil through the filtration system. It allows oil to pass through a filter medium, trapping contaminants and impurities. This process maintains the cleanliness of the oil, which is essential for lubricating engine components and ensuring smooth operation ¹.

Purpose of the Lubricating Oil Filter Head

In truck operations, the Lubricating Oil Filter Head contributes to engine efficiency and longevity by ensuring that the oil circulating through the engine remains free of contaminants. This reduces wear on engine parts, maintains optimal engine performance, and extends the engine’s lifespan ².

Key Features

The Cummins Lubricating Oil Filter Head is designed with features that enhance its performance. These include robust construction for durability, high-quality materials to withstand harsh engine conditions, and a design that facilitates easy installation and maintenance. It may also incorporate a pressure relief valve to prevent damage from over-pressurization ³.

Benefits

The advantages of the Lubricating Oil Filter Head include improved engine protection due to cleaner oil, extended oil life as contaminants are effectively removed, and enhanced overall engine performance. These benefits contribute to the reliability and efficiency of the truck’s engine system.

Installation Process

Proper installation of the Lubricating Oil Filter Head involves ensuring the engine is cool and the oil has been drained. The old filter head should be removed, and any gaskets or O-rings should be inspected and replaced if necessary. The new filter head should be installed according to the manufacturer’s instructions, ensuring all connections are secure. After installation, the engine oil should be refilled to the appropriate level.

Common Issues and Troubleshooting

Frequent problems associated with the Lubricating Oil Filter Head may include oil leaks, difficulty in installation or removal, and contamination of the oil due to a faulty filter. Troubleshooting steps may involve inspecting the filter head for damage, ensuring all connections are tight, and replacing the filter head if it is found to be defective.

Maintenance Tips

To ensure the Lubricating Oil Filter Head operates efficiently, regular maintenance practices are recommended. This includes inspecting the filter head during routine oil changes for signs of wear or damage, and replacing it according to the manufacturer’s guidelines or when signs of contamination are observed in the oil. Adhering to these practices helps maintain the integrity of the engine’s lubrication system.

Role of Part 3918290 Lubricating Oil Filter Head in Engine Systems

The lubricating oil filter head, identified as part 3918290, is an integral component in the efficient operation of engine systems. It interfaces directly with the engine’s lubrication circuit, ensuring that clean, filtered oil is consistently supplied to vital engine components.

Interaction with the Engine Oil Cooler

The lubricating oil filter head plays a significant role in maintaining the optimal temperature of the engine oil. As oil circulates through the engine, it absorbs heat. The oil then passes through the oil cooler, where it is cooled before returning to the engine. The lubricating oil filter head ensures that the oil entering the cooler is free from contaminants, which could otherwise impede heat exchange efficiency or cause blockages within the cooler’s passages.

This component is designed to work in harmony with the oil cooler to sustain a balanced oil temperature, which is essential for the longevity and performance of the engine. The filtered oil, after being cooled, is directed back into the engine, where it lubricates moving parts, reduces friction, and helps in dissipating heat away from critical components.

Conclusion

In summary, the Lubricating Oil Filter Head (3918290) is a key player in the engine’s lubrication system, working alongside components like the engine oil cooler to ensure that the engine operates within its designed parameters, promoting efficiency and reliability.
