3979506 | Cummins QSB6.7 Camshaft, New

The Cummins NT855 camshaft is a crucial component in the engine's valve train system. Its purpose is to open and close the engine's intake and exhaust valves at the proper time, allowing air and fuel to enter the engine and exhaust gases to exit. 

 

The camshaft is driven by the engine's crankshaft via a timing chain or belt, and its shape and position determine the valve timing and lift. The cam lobes on the camshaft push against the valve lifters, which in turn push against the pushrods, rocker arms, and valves to open and close them.

 

Proper camshaft operation is essential for engine performance and efficiency. A worn or damaged camshaft can cause poor fuel economy, reduced power output, and even engine damage if valves are not opening and closing correctly. Therefore, regular inspection and maintenance of the camshaft is important to ensure the engine's longevity and performance.
