Buy wp20323 - Genuine Cummins Camshaft - wisentpartscenter.com

Description

Genuine Cummins 3924471 Camshaft controls the opening and closing of the engine’s intake and exhaust valves on Cummins 6C-series 8.3L engines. Its machined lobes work through the valve-train components to keep valve movement synchronized with crankshaft position, allowing each cylinder to breathe correctly throughout the combustion cycle.

Key Functions
- Controls intake and exhaust valve timing as the engine rotates.
- Transfers cam-lobe motion through the valve train to open and close the valves.
- Keeps valve events synchronized with piston movement for proper cylinder filling and exhaust flow.

Verify fitment with us before ordering to ensure the correct part for your application.

Purpose of the Part

The 3924471 determines when the intake and exhaust valves open and how long they remain open as the engine runs. Correct camshaft timing and lobe condition are critical because even small changes in valve movement can affect cylinder breathing, combustion quality, power, and overall engine operation.

Issue Symptoms / When to Replace

Camshaft wear can show up as valve-train noise, reduced engine performance, uneven cylinder operation, or abnormal valve lash that repeatedly changes after adjustment. Worn or damaged lobes can also reduce valve lift. Because lifter, rocker, pushrod, valve, and adjustment problems can create similar symptoms, the complete valve train should be inspected before condemning the camshaft.

Brand Information

Cummins was founded in Columbus, Indiana in 1919 and has manufactured diesel engines and engine components for more than a century. Its C-Series 8.3L engine family has been used across commercial, industrial, agricultural, construction, and power applications, with Cummins supplying the internal valvetrain components specified for each engine build and CPL. Cummins’ current parts catalog still identifies 3923478 specifically for the 6CTA 8.3L platform.

How to Identify an OEM Part

A genuine 3924471 can be identified by the Cummins part number permanently engraved directly into the camshaft. This physical marking is the strongest OEM identifier when the original packaging is no longer available.
