Role of Part 3949692 Oil Suction Connection in Engine Systems

The Oil Suction Connection, identified by part number 3949692, is an integral component in the lubrication system of an engine. It is specifically designed to facilitate the efficient transfer of oil from the oil pan to the engine’s lubrication system.

Integration with the Long Block

In the context of a long block, which includes the cylinder block, crankshaft, pistons, and other essential components, the Oil Suction Connection plays a significant role. It is typically mounted on the oil pan and is connected to the oil pump. This connection ensures a steady flow of oil from the pan to the pump, which then circulates the oil throughout the engine to lubricate moving parts, reduce friction, and dissipate heat.

Functionality in the Long Block Kit

When considering a long block kit, which may include additional components such as gaskets, seals, and sometimes even the oil pan, the Oil Suction Connection is a key element. It ensures that the oil pump can draw oil effectively from the pan, maintaining the necessary lubrication for the engine’s internal components. Proper installation and sealing of this connection are essential to prevent oil leaks and ensure optimal engine performance.

Interaction with the Oil Pan

The oil pan serves as the reservoir for the engine’s lubrication system. The Oil Suction Connection is directly interfaced with the oil pan, usually through a dedicated port. This setup allows for the oil pump to suction oil from the pan efficiently. The design of the connection must accommodate the oil pan’s shape and the pump’s requirements to ensure a consistent oil flow.

Ensuring Adequate Oil Supply to the Engine

The primary function of the Oil Suction Connection is to maintain an adequate supply of oil to the engine. By securely connecting to the oil pan and the oil pump, it ensures that the engine receives a continuous flow of lubricant. This is essential for the longevity and reliability of the engine, as proper lubrication reduces wear and tear on critical components such as bearings, pistons, and the crankshaft.

Conclusion

In summary, the Oil Suction Connection (part 3949692) is a vital component in the engine’s lubrication system, ensuring that oil is efficiently drawn from the oil pan and circulated throughout the engine to maintain optimal performance and longevity. Its compatibility with various Cummins engines, coupled with its robust design and reliable performance, makes it an essential part for heavy-duty applications.
