Rod Bearing - 5.9L Cummins Diesel 89-02

The Rod Bearing - 5.9L Cummins Diesel 89-02 is a critical internal engine component built to withstand the extreme pressures and temperatures generated by high-output diesel combustion. If you operate a boat, truck, or marine vessel powered by a first or second-generation 5.9L Cummins engine, this bearing keeps your crankshaft centered and rotating smoothly under load. Whether you're cruising open water or hauling heavy cargo, a worn or damaged rod bearing will cause catastrophic engine failure—making this OEM-equivalent replacement an essential maintenance item for any serious diesel operator.

Manufactured by MAHLE ORIGINAL/CLEVITE under part number CB1413V, this rod bearing is engineered to the same exacting standards as factory equipment. The bearing uses a precision-molded bimetallic construction—a thin layer of copper-lead alloy bonded to a steel backing—which allows it to conform slightly to the crankshaft journal while maintaining dimensional stability under sustained high-RPM operation. The CB1413V delivers superior load capacity and thermal conductivity compared to inferior aftermarket alternatives, ensuring consistent oil film thickness and metal-to-metal separation even during aggressive throttle or towing conditions.

Diesel boaters and fleet operators who perform in-frame engine rebuilds or rod bearing replacement will find this bearing compatible with Dodge Ram, Freightliner, and other platforms running the 1989–2002 5.9L Cummins engine block. Installation requires precision honing and proper torque procedures; most shops recommend replacing the full rod bearing set during any major teardown to ensure uniform wear characteristics across all cylinders. Its compact 2.35 x 1.35 x 3.2 inch profile and light 0.265 lb weight make handling straightforward, and the MAHLE brand heritage guarantees fitment accuracy and long service life on the water or road.
