Role of the Cummins 3417076 Threaded Plug in Engine Systems

The Cummins 3417076 Threaded Plug is an essential component in various engine systems, facilitating the secure and efficient operation of several critical assemblies.

In aftercooler plumbing, the threaded plug ensures that connections are sealed properly, preventing coolant leaks and maintaining optimal cooling efficiency for the compressed air.

For base parts, it provides a reliable sealing solution where different components interface, ensuring no fluid or gas escapes, which is vital for the integrity of the engine’s foundational structure.

In the camshaft and camshaft and gear systems, the threaded plug is used to seal off passages or bolt holes, ensuring that the camshaft operates within a sealed environment, which is necessary for precise valve timing and engine performance.

The check valve system utilizes the threaded plug to maintain unidirectional flow, preventing backflow which could lead to inefficient engine operation.

Within the connecting rod and piston assembly, the threaded plug may be employed to seal oil passages, ensuring that lubrication is directed correctly to reduce friction and wear.

In the cylinder head and cylinder head mounting, the threaded plug plays a role in sealing coolant or oil passages, which is essential for thermal management and lubrication of the cylinder head components.

For EBM (Engine Build Module): Performance Parts and EBM: Device, the threaded plug is critical in sealing high-pressure passages, contributing to the enhanced performance characteristics of these specialized components.

In timing control systems, the threaded plug ensures that timing passages are sealed, which is important for the accurate delivery of timing fluids or gases that control valve operation.

The fuel connection and injector plumbing systems rely on the threaded plug to maintain fuel integrity by sealing connections, which is fundamental for consistent fuel delivery and combustion.

When dealing with oil connections, the threaded plug is used to seal oil lines and passages, ensuring that oil pressure is maintained for lubrication purposes.

In the complex oil control (top level assembly) valve, oil control top level assembly valve, and oil control valve valve systems, the threaded plug is instrumental in sealing various oil passages, which is crucial for the modulation of oil flow to different engine components.

The oil manifold system uses the threaded plug to seal off individual oil passages, ensuring that oil is distributed correctly throughout the engine.
