Taken together, the catalogue walks a shop from the complete engine assembly (part 6275-A0-RA20) through every mounting cushion, air-cleaner hose, KCCV ventilator and element kit, radiator and oil-cooler pack, fuel cooler, condenser, coolant piping, and sub-tank, then onward into fuel, electrical, hydraulic, frame, cab, guards, swing, travel, undercarriage, and work-equipment illustrations. Each figure pairs an exploded drawing with an index of part numbers, descriptions, quantities, and the F40003-and-up serial note so replacements stay matched to this short-tail excavator.

How to use the figures and indexes

Every illustrated figure carries a figure code such as B0100-001001 or C0100-001006. The facing index lists INDEX NO., PART NO., DESCRIPTION, Q’TY, and SERIAL NO. Match the callout on the drawing to the index row, confirm quantity and the SN:F40003– line, then order by the printed part number. Fasteners, washers, O-rings, and clamps are called out individually so a partial rebuild does not omit a seal or clip that belongs only on this serial range.

Who this catalogue serves

The Komatsu PC138US-10 Serial F40003-Up Machine Parts Catalogue is written for owners, fleet mechanics, and parts counters who need the exact component for a PC138US-10 in the F40003-and-up range. It is a parts identification book, not a step-by-step service manual; it tells you what to order and where it sits in the assembly so downtime is spent waiting on the right part instead of the wrong one.

Get the parts list that matches this serial range

With this Komatsu PC138US-10 Serial F40003-Up Machine Parts Catalogue you can identify engine mounts, KCCV parts, radiator and cooler hardware, hoses, clamps, and the remaining machine sections down to individual fasteners. Correct part numbers matter because a look-alike cushion, hose, or cooler from another serial group will not bolt up or seal. After payment the PDF is delivered immediately—no shipping—so you can open it on a shop computer, tablet, or phone and print the figure you need at the bench.
