Role in Engine Systems

The 4931967 Threaded Plug is a component in various engine systems, particularly in the management and control of oil within the engine. This component is specifically designed to interface with the oil drain plug, ensuring a secure and leak-free connection when draining oil from the oil pan.

When maintaining or servicing an engine, the oil drain plug is unscrewed from the oil pan to allow the old oil to be expelled. The 4931967 Threaded Plug plays a significant role here by providing a reliable seal that prevents oil leakage during normal operation. Its threaded design ensures a tight fit, which is vital for maintaining the integrity of the oil system.

Additionally, the 4931967 Threaded Plug is involved in the process of refilling the oil pan with fresh oil. After the old oil has been drained, the plug is removed, and new oil is poured into the pan. Once the oil level reaches the required mark, the plug is reinserted and tightened to seal the pan, ensuring that the new oil remains contained within the system.

Conclusion

In summary, the Cummins Threaded Plug 4931967 is a key component in the efficient and safe operation of the engine’s oil system, facilitating both the draining and refilling processes while maintaining a secure seal on the oil pan. Its design, durability, and compatibility with various Cummins engines make it an essential part for ensuring the reliability and performance of commercial trucks.
