Oil pump for Mercedes-Benz OM401

The oil pump OM401/2 is a mechanical component responsible for circulating engine oil under pressure to the moving parts within the Mercedes-Benz OM401 and OM402 series engines. By delivering a constant flow of lubricant to the crankshaft, connecting rods, camshafts, and pistons, the pump ensures that these surfaces remain coated to minimize friction and assist in heat dissipation during operation.

This component is engineered to meet the specific pressure and flow requirements of the OM401 and OM402 engine platforms. It is compatible with these engine series, which are commonly found in heavy-duty trucks, buses, and various industrial machinery applications. Proper installation and function of this pump are necessary to maintain the internal lubrication circuit of the engine.

In any internal combustion engine, the oil pump serves as the heart of the lubrication system. It draws oil from the sump and forces it through the oil galleries and filter to reach critical friction points. Maintaining consistent oil pressure is essential for the operation of the engine's rotating and reciprocating assemblies.
