Oil pump for Mitsubishi 4D56

The oil pump with part number 2134042800 is engineered for the Mitsubishi 4D56 engine, which is utilized in various industrial cranes and heavy machinery. This component is responsible for drawing oil from the crankcase and circulating it through the lubrication galleries to critical moving parts, including the crankshaft, camshafts, connecting rods, and pistons. By maintaining consistent oil pressure, the pump facilitates the reduction of friction and the dissipation of heat within the engine assembly.

This specific oil pump is compatible with the Mitsubishi 4D56 engine model. Proper operation of this component is necessary to ensure that all internal surfaces receive sufficient lubrication to prevent premature wear or mechanical failure of the engine block and its associated rotating assemblies.

In internal combustion engines, the oil pump serves as the primary mechanism for maintaining the lubrication circuit. It converts mechanical rotation from the engine into hydraulic flow, ensuring that oil reaches the bearings and valve train to support continuous operation under load.
