Compatibility with Cummins Engines

The Cummins part number 3641725, an Oil Pan, is designed to fit seamlessly with several models of Cummins engines. Specifically, this oil pan is compatible with the QSK50 CM2150 MCRS and QSK50 CM2350 K108 engines.

For the QSK50 CM2150 MCRS engine, the oil pan is engineered to ensure optimal oil flow and storage, maintaining the engine’s lubrication system’s integrity. It is crafted to fit precisely with the engine’s design, ensuring that it can hold the required amount of oil while also providing easy access for maintenance and oil changes.

Similarly, for the QSK50 CM2350 K108 engine, the oil pan is tailored to meet the specific requirements of this engine model. It is designed to integrate smoothly with the engine’s architecture, ensuring that the oil is contained effectively and that the lubrication system operates efficiently. The fitment of the oil pan is critical for maintaining the engine’s performance and longevity.

Both engine models benefit from the use of the Cummins part number 3641725 oil pan, as it is made from high-quality materials that can withstand the rigors of engine operation. This ensures that the oil pan remains durable and reliable, providing long-lasting support for the engine’s lubrication system.

Role of Part 3641725 Oil Pan in Engine Systems

Part 3641725, the Oil Pan, is an integral component in the lubrication system of an engine. It serves as the reservoir for engine oil, which is essential for the proper functioning and longevity of the engine.

The Oil Pan collects oil that has circulated through the engine and lubricated various moving parts. This oil, after performing its duty, drains back into the pan due to gravity. The pan’s design ensures that the oil is stored in a manner that allows for efficient pumping back into the engine by the oil pump.

In conjunction with the oil pump, the Oil Pan maintains a continuous cycle of oil circulation. The pump draws oil from the pan and sends it through the oil filter, which removes contaminants. The clean oil is then distributed to critical engine components such as the crankshaft, camshaft, valve train, and pistons.

The Oil Pan also plays a role in temperature regulation. As oil absorbs heat from the engine components it lubricates, it carries this heat back to the pan. Some engines are equipped with an oil cooler, which may be integrated into the Oil Pan design to help dissipate this heat and maintain optimal oil temperature.

Additionally, the Oil Pan often includes features such as baffles to minimize oil surge during operation, ensuring a consistent oil level for the pump to draw from. Some designs may also incorporate an oil level sensor, which provides feedback to the engine control unit (ECU) for monitoring and maintaining appropriate oil levels.

Conclusion

In summary, the Cummins 3641725 Oil Pan is a fundamental component that supports the lubrication system by storing, circulating, and cooling engine oil, thereby contributing to the overall efficiency and reliability of the engine. Its robust design, compatibility with specific Cummins engines, and key features make it a valuable component in maintaining the performance and longevity of commercial truck engines.
