Cummins Lubricating Oil Pump Drive Shaft (Part 3235120) Compatibility

The Cummins Lubricating Oil Pump Drive Shaft, identified by the part number 3235120, is a critical component in the engine’s lubrication system. This part ensures that the oil pump operates efficiently, maintaining the necessary lubrication for the engine’s moving parts.

K19 Engine Series

The K19 engine series is known for its robust design and reliability, often used in heavy-duty applications. The Lubricating Oil Pump Drive Shaft (3235120) is specifically engineered to fit seamlessly within this engine series. The drive shaft interfaces directly with the oil pump, ensuring that it can rotate smoothly and efficiently. This design is crucial for maintaining the oil flow necessary for the engine’s operation, particularly under high-stress conditions.

Grouping of Compatible Engines

While the K19 series is a notable example, the drive shaft (3235120) is also compatible with other Cummins engines that share similar design characteristics and lubrication system requirements. These engines often include:

• K19-C440: A variant of the K19 series, designed for applications requiring high power output and durability.
• K38: Another series known for its reliability and efficiency, often used in industrial and marine applications.
• KT19: A turbocharged version of the K19, providing enhanced performance and efficiency.

These engines, while differing in specific applications and power outputs, share a common requirement for a reliable and efficient lubrication system. The drive shaft (3235120) is designed to meet these requirements, ensuring that the oil pump operates smoothly and efficiently across different engine models.

Role of Part 3235120 Lubricating Oil Pump Drive Shaft in Engine Systems

The lubricating oil pump drive shaft, specifically part 3235120, is integral to the operation of both the lubricating oil pump and the scavenge pump within an engine system. This component ensures the efficient transfer of mechanical energy from the engine’s rotating components to the pumps, facilitating the circulation of lubricating oil throughout the engine.

Lubricating Oil Pump Integration

In the lubricating oil pump system, the drive shaft connects to the pump’s rotor. As the drive shaft rotates, it imparts motion to the rotor, which in turn draws oil from the sump and pressurizes it. This pressurized oil is then distributed through the engine’s lubrication circuits, ensuring that all moving parts receive adequate lubrication. The consistent rotation of the drive shaft is essential for maintaining a steady oil flow, which is vital for reducing friction and wear on engine components.

Scavenge Pump Interaction

The scavenge pump, also known as the scavenging pump, plays a role in removing unwanted substances from the engine’s lubrication system. The drive shaft for the lubricating oil pump often extends to power the scavenge pump as well. This setup allows for simultaneous operation of both pumps, enhancing the efficiency of the lubrication system. The scavenge pump helps in maintaining clean oil by removing contaminants and ensuring that the oil remains effective over time.

Overall System Efficiency

The integration of part 3235120 within these pump systems enhances the overall efficiency of the engine’s lubrication process. By providing a reliable means of transferring rotational energy, the drive shaft ensures that both the lubricating oil pump and the scavenge pump operate in sync. This coordinated operation is essential for maintaining optimal engine performance and longevity.

Conclusion

The Lubricating Oil Pump Drive Shaft 3235120 by Cummins is a vital component in the lubrication system of heavy-duty engines. Its role in ensuring consistent oil flow, reducing friction, and maintaining engine performance underscores its importance. Proper installation, maintenance, and troubleshooting are essential for maximizing the benefits of this Cummins part.
