Connecting rod bearing for Cummins 6BTAA5.9-C178

The connecting rod bearing, part number 3016761, is a precision component installed within the internal combustion engine. It provides a low-friction surface between the connecting rod and the crankshaft, allowing the rod to rotate around the crankshaft journal while transferring force from the piston. This component is necessary for the rotational movement of the engine assembly.

This part is compatible with several Cummins engine models, specifically the 6BTAA5.9-C178, KTA38C-1050, QSM11-C335, and QSM19-C700. These engines are frequently utilized in cranes, heavy machinery, and various industrial equipment. Proper installation and maintenance of these bearings ensure the required clearance for oil film formation, which separates the moving metal surfaces during engine operation.

Connecting rod bearings function by supporting the loads generated during the combustion cycle. They are engineered to maintain the necessary gap for hydrodynamic lubrication, which prevents direct metal-to-metal contact between the rod and the crankshaft. Regular inspection of these bearings is standard practice during engine overhauls to maintain the mechanical integrity of the rotating assembly.
