5.9 C OE Intake Rocker Lever

Part: 5.9 C OE Intake Rocker Lever

Part Number: 3937220

Manufacturer: Cummins

Description:

This part refers to a Cummins 5.9L engine Intake Rocker Lever. This component is a critical part of the valve train system in a diesel engine, specifically involved in the operation of the engine’s intake valves.

The Intake Rocker Lever is responsible for transferring the motion from the camshaft to the intake valve in a Cummins 5.9L engine. It works as part of the rocker arm assembly, which plays a vital role in opening and closing the intake valves in sync with the engine’s combustion cycle.

As the camshaft rotates, it pushes against the rocker arm, which in turn moves the rocker lever. This movement opens the intake valve at the appropriate time during the engine’s intake stroke. The lever is crucial for ensuring that the intake valve opens at the right moment, allowing air (or the air-fuel mixture in some engines) into the combustion chamber for the next cycle.

The rocker lever is typically made from hardened steel or other durable materials to withstand the constant stress and heat generated during engine operation. These materials are chosen for their resistance to wear and heat, ensuring a long lifespan in the harsh environment inside the engine.
