A numerical index at the end of the book cross-references every part number to its figure and index position, making lookups fast when you already know the number.

Why This Parts Book Matters

Ordering the wrong part on a 39-tonne excavator is expensive in both money and downtime. The PC390LC-8M0 Parts Book removes the guesswork. Each exploded illustration shows exactly how a component is assembled, which fasteners and seals go where, and how many of each are required. The index-number system links every part on the drawing to its part number, description, quantity and serial range in the accompanying list, so you can confirm that the part you are about to order was actually fitted to your machine — whether it is an early 81354-series unit or a later build.

This is the same document Komatsu distributors use when they look up parts for the PC390LC-8M0. Whether you are rebuilding a control valve, replacing a final drive seal, refreshing the undercarriage, ordering a new bucket or sourcing a breaker adapter, the exact part numbers are here. The multilingual foreword and the English parts listings make it usable for workshops and parts departments across different regions.
