Crankshaft gear for Mercedes-Benz OM401

The crankshaft gear A4030500403 serves as a synchronization component within the Mercedes-Benz OM401 engine. Mounted directly onto the crankshaft, this gear transmits rotational movement to the camshaft and, depending on the specific engine configuration, to the fuel injection pump. Its primary function is to maintain precise timing between the piston movement, valve operation, and fuel injection cycle.

This component is compatible with the Mercedes-Benz OM401 engine series. Proper installation and alignment of this gear are necessary to maintain the rotational timing of the engine assembly.

In internal combustion engines, the crankshaft gear acts as the driving element for the timing system. By maintaining a fixed gear ratio with the driven components, it ensures that the mechanical sequence of the engine remains consistent throughout its operational range.
