FAQ

Q: What is the difference between an eccentric shaft and a standard camshaft?
A: In this context, “eccentric shaft” is a specific term for the camshaft used in Cummins M11 engines. It performs the same function—controlling the intake and exhaust valves—but is referred to by this name due to its design for the unit injector system. It is a direct replacement for the standard camshaft in these engines.

Q: Can this eccentric shaft be used in a Cummins ISM engine?
A: No, this specific part (4922089) is designed for the Cummins M11 and C Series engines. The Cummins ISM engine uses a different camshaft design. Please verify your engine model and part number before purchasing.

Q: What are the signs of a failing eccentric shaft?
A: Common symptoms include rough engine running, loss of power, poor fuel economy, excessive valve train noise (clattering), and potential engine misfire. If you experience these issues, inspect the camshaft and lifters for excessive wear or scoring. Replacing the shaft and related components (lifters, bearings) is recommended for a complete overhaul.
