Using Komatsu PC400LC-8 Excavator Parts Catalog

This Komatsu PC400LC-8 excavator parts catalog helps you locate aftermarket replacement parts by machine system and assembly. Its current coverage contains 359 assembly listings across 21 source sections. The navigation groups related sections for easier browsing; available choices include Engine, Hydraulic System, Undercarriage, Work Equipment and Electrical System.

Choose the section relevant to your repair, then compare the full Komatsu PC400LC-8 model designation, machine serial range and any engine or attachment information on the assembly page. Model suffixes, serial breaks and configuration notes remain important even where two diagrams look similar.

The published engine listings identify SAA6D125E-5-FR (engine serial 660001-UP) and SAA6D125E-5F (engine serial 562304-UP). These are catalog applications, not a claim that every machine in this model series uses the same engine configuration.

Use the part-number links to inspect listed store products, or select the required parts and quantities to prepare a quote. Only the published sections are shown here; the catalog does not imply that every original book section or machine configuration is available.
