Using Komatsu PC400LC-8 Piston Pump, Inner Parts (4/12) (#70199-) Parts
Use the Komatsu PC400LC-8 Piston Pump, Inner Parts (4/12) (#70199-) Parts listing to identify aftermarket replacement parts within the hydraulic system section. This excavator application is listed for machine serial 70001-UP; the diagram and parts table retain the selected configuration and its source notes.
The parts table contains 31 listed part occurrences, including pump assembly (reference 708-2H-00450), pump subassembly (reference 708-2H-01450) and slider (reference 708-2H-34150). Read any option and reference notes beside these entries before choosing a replacement; repeated references may represent separate positions in the source list.
For hydraulic replacement parts, compare the listed circuit, cylinder, valve or hose application wherever identified in the selected assembly. Retain connection and configuration notes when requesting a quote rather than relying on appearance alone.
Catalog quantities describe the illustrated assembly. Adjust the order quantity to what you need, select the relevant rows, and use Add selected to cart for verified store matches or Add selected to quote for quote items. The diagram alone does not establish current stock or part interchangeability.
