Crankshaft for Mercedes-Benz OM402

The crankshaft OM402/A serves as the primary rotating component within the Mercedes-Benz OM402 engine. It is responsible for converting the linear reciprocating motion of the engine pistons into rotational motion, which is subsequently transferred to the transmission system to drive the machinery. The component features precision-machined connecting rod journals and main bearing journals that facilitate its installation within the engine block and connection to the internal rotating assembly.

This component is manufactured by Mercedes-Benz to meet the specific dimensional and balance requirements of the OM402 engine series, which is utilized in heavy trucks, buses, and industrial equipment. Proper installation and alignment of the crankshaft are required to ensure the correct operation of the engine and to maintain the specified power output during operation.

In internal combustion engines, the crankshaft acts as the central axis for the power stroke. It must withstand the forces generated by the combustion process and the inertia of the moving pistons. By providing a stable rotational path, the crankshaft allows for the smooth delivery of torque throughout the engine cycle.
