4980462 | Cummins ISB Crankshaft, New 5.9 L and 6.7 L - ISB / QSB Series

The crankshaft in a Cummins engine is a crucial component that converts the up and down motion of the engine's pistons into rotational motion. Its primary function is to provide the engine with a smooth and continuous power output by transferring the energy generated by the combustion process to the transmission and ultimately to the wheels.

 

The crankshaft is responsible for synchronizing the movement of the pistons with the timing of the valves, ensuring that the engine runs smoothly and efficiently. It also helps to maintain engine balance and stability by counteracting the force generated by the pistons during their upward and downward movements.
