Supporting the efficient operation of hydraulic systems, the 708-2H-33311 Komatsu Hydraulic Pump Piston, coded as 708-2H-33311, is designed to maintain pressure balance in heavy-duty machinery such as excavators and dozers. This component offers a working principle compatible with high pressure in the internal mechanism of the main hydraulic pumps found in crawler excavators and loaders.
During the replacement process of hydraulic pump elements, the cleanliness of the system and the condition of the lubrication channels are of great importance. Ensuring that the hydraulic oil is fresh and filtered during the installation of these operating elements inside the pump is among the factors that directly affect the service life of the component. Additionally, paying attention to manufacturer tolerances during disassembly and assembly prevents a drop in hydraulic flow performance.
To ensure full compatibility with the hydraulic pump structure used in your PC400-8, PC450-8, PC550-8, D155AX-6, WA500-6 and D85EX-15 machines, please verify the part number from your machine's pump label.
