Camshaft for Mercedes-Benz OM402

The camshaft A4020501801 serves as a rotating component within the Mercedes-Benz OM402 internal combustion engine. Its primary function involves controlling the opening and closing sequences of the intake and exhaust valves, which is necessary for the engine combustion cycle and overall operation. The component features lobes with specific profiles that actuate the valve train, including tappets or rocker arms, at the required intervals during the engine cycle. This synchronized movement facilitates the intake of the air-fuel mixture into the cylinders and the subsequent expulsion of exhaust gases.

This part is compatible with the Mercedes-Benz OM402 engine, which is frequently utilized in heavy-duty trucks, buses, and various industrial machinery, including specific crane models and construction equipment. Maintaining the correct valve timing is necessary for the engine to operate within its design parameters. Accurate valve operation ensures proper cylinder filling and scavenging, which influences the power output and efficiency of the power unit. The camshaft is a critical element in the valve train assembly of the OM400 series engines.
