The crankshaft 3089797 facilitates the conversion of linear piston movement into rotational energy within the Cummins K50 and K T50 diesel engine series. This component features precision-machined connecting rod journals and main bearing journals that interface with the engine block and connecting rods to transfer power effectively throughout the drivetrain.
This part is compatible with Cummins K50 and K T50 engine configurations. It is manufactured by Cummins to meet the specific dimensional and structural requirements of these heavy-duty power units. The design incorporates specific bearing surfaces that allow the component to rotate within the engine block while supporting the forces generated during the combustion cycle.
In internal combustion engines, the crankshaft acts as the central rotating element that transmits torque to the flywheel and transmission system. Proper alignment and surface integrity of the journals are necessary to maintain the rotational balance and lubrication efficiency required for the engine to operate under load.
