Crankshaft for Mercedes-Benz OM402

The crankshaft A4020302301 serves as a primary component within the Mercedes-Benz OM402 diesel engine. It functions by converting the linear, reciprocating motion generated by the engine pistons into the rotational movement necessary to drive the machine transmission and auxiliary systems. This component features precision-machined connecting rod journals and main bearing journals, which provide the required support points for the engine assembly to rotate within the engine block.

This part is compatible with the Mercedes-Benz OM402 engine series. The component is manufactured by Mercedes-Benz to meet the specific dimensional and balance requirements of this engine platform. Proper installation and alignment of the crankshaft are necessary to ensure the engine operates within its intended mechanical parameters.

In heavy machinery engines, the crankshaft acts as the central rotating shaft that manages the power output of the combustion cycle. It must maintain structural integrity while subjected to the forces of combustion and the continuous rotational load of the engine operation. The journals must remain within specified tolerances to support the bearings and maintain proper oil clearance for the engine lubrication system.
