Oil pump P71 for Mercedes-Benz OM 442

The P71 oil pump, part number 4031801701, functions within the lubrication system of the Mercedes-Benz OM 442 engine. It draws oil from the sump and delivers it under pressure through internal galleries and filters to moving components such as the crankshaft, connecting rods, pistons, camshaft, and turbocharger. By maintaining a continuous flow of lubricant, the pump manages friction and heat across these internal engine parts.

This component is engineered for compatibility with the Mercedes-Benz OM 442 diesel engine, which is frequently found in heavy machinery, trucks, and cranes. The pump design integrates with the engine architecture to support the lubrication requirements of this specific power unit.

Oil pumps in diesel engines typically utilize gear or rotor mechanisms to generate the necessary flow and pressure. These pumps often include an integrated pressure relief valve to regulate system pressure and prevent over-pressurization. The pump ensures that oil reaches all critical contact surfaces, which is necessary for the operation of heavy-duty internal combustion engines.
