Cummins Engine Part 4308111: Oil Suction Connection

The Cummins part number 4308111, identified as an Oil Suction Connection, is a critical component in the lubrication system of several Cummins engines. This part ensures that oil is effectively drawn from the oil pan and supplied to the engine’s lubrication system, which is essential for maintaining engine health and performance.

VTA903 and CM2250 Engines

The Oil Suction Connection part 4308111 is integral to the VTA903 and CM2250 engines. These engines, known for their robust design and reliability, require precise lubrication to function optimally. The oil suction connection facilitates the smooth flow of oil, ensuring that all moving parts are adequately lubricated, which helps in reducing friction and wear, and ultimately extends the engine’s lifespan.

V105 Engine

Similarly, the V105 engine also utilizes the Oil Suction Connection part 4308111. This engine is designed for heavy-duty applications, and the efficient operation of its lubrication system is paramount. The oil suction connection in this engine ensures that the oil is drawn efficiently from the oil pan and distributed throughout the engine, maintaining the necessary lubrication levels to handle the demanding conditions of its intended use.

Grouping of Engines

The VTA903 and CM2250 engines, while distinct in their specific applications and configurations, share a commonality in their requirement for the Oil Suction Connection part 4308111. This part’s role in these engines is to maintain the integrity of the lubrication system, ensuring that oil is consistently and effectively circulated. The V105 engine, on the other hand, also relies on this part to manage the high demands of its heavy-duty operations, highlighting the universal importance of the Oil Suction Connection in Cummins engines.

Role of Part 4308111 Oil Suction Connection in Engine Systems

The part 4308111 Oil Suction Connection is an essential component in the lubrication system of an engine, facilitating the efficient circulation of oil. This component is strategically positioned to interface with the oil pan, which serves as the reservoir for the engine oil.

Interaction with the Oil Pan

The Oil Suction Connection is designed to connect to the oil pan, allowing it to draw oil from the pan’s sump. This connection ensures a consistent supply of oil is available for the engine’s lubrication system. The design of the connection point is typically threaded or flanged to create a secure seal, preventing any oil leaks that could lead to a loss of lubrication and potential engine damage.

Oil Circulation Process

Once the Oil Suction Connection has drawn oil from the pan, it directs the oil towards the oil pump. The pump then pressurizes the oil and distributes it throughout the engine’s moving parts. This process is vital for reducing friction, dissipating heat, and removing contaminants from the engine’s internal components ³.

Maintenance and Efficiency

Regular maintenance of the Oil Suction Connection is important to ensure the longevity and efficiency of the engine’s lubrication system. Any blockages or leaks in this component can lead to inadequate oil supply, which may result in increased wear on engine parts and reduced performance. Engineers and mechanics should inspect this connection during routine maintenance checks to ensure it is functioning correctly and is free from debris or corrosion.

Conclusion

In summary, the 4308111 Oil Suction Connection plays a significant role in the engine’s lubrication system by ensuring a reliable flow of oil from the oil pan to the pump, which is essential for the engine’s operation and durability.
