FAQ

1. What are the symptoms of a bad valve push rod on a Cummins NT855 engine?

A worn or bent push rod can cause a ticking noise from the valve cover, reduced engine power, misfiring, or a check engine light related to valve timing. If you suspect a push rod issue, it is critical to inspect the entire valve train. This 3046420 push rod is a direct replacement to restore proper engine function.

2. Is this push rod a direct replacement for the OEM Cummins part?

Yes. This part is manufactured to OEM specifications (OEM Size) and is a direct replacement for the original Cummins part number 3046420. No modifications or special tools are required for installation, provided the engine’s valve lash is adjusted to factory specifications after replacement.

3. How should I maintain or inspect my valve push rods during engine service?

During routine overhead maintenance, visually inspect each push rod for straightness. Roll the rod on a flat surface to check for bends. Also, check the ball ends for pitting or excessive wear. If any rod is found to be damaged, it is best practice to replace all push rods in the engine to ensure uniform performance and prevent future failures.
