Cummins 4992926 Connecting Rod Assembly

The Cummins 4992926 connecting rod is a critical internal engine component designed to convert reciprocating piston motion into rotational crankshaft motion. Manufactured from high-strength forged steel, it undergoes precision machining and heat treatment to withstand high combustion pressures and inertial forces in heavy-duty applications. This part serves as a direct replacement for Cummins OEM part numbers 4993830, 4993829, 4993824, 4944475, 4993823, and 4992924. It is engineered for the B3.3 and QSB3.3 engine platforms commonly deployed in construction machinery, industrial equipment, and commercial vehicles. Each rod includes the big-end bearing housing and small-end bushing bore, ready for assembly with OEM-spec bearings and piston pins.
