Komatsu PC210-3KP, PC210LC-3KP, PC240-3KP, PC240LC-3KP, PC240NLC-3KP Parts Catalog

If you are ordering parts for any of these five Komatsu excavator models – PC210-3KP, PC210LC-3KP, PC240-3KP, PC240LC-3KP, PC240NLC-3KP – you already know that one wrong digit on a part number means a week of downtime waiting for the correct shipment. This is the factory Parts Catalog that Komatsu dealers use. 388 pages of nothing but group numbers, figure numbers, and the exact interchange codes that tell you what fits what and what supersedes what.

Every page in this book came from the same press that prints the manuals for Komatsu service bays. The foreword alone – page 3 of the PDF – spells out the code system for STD, LC, and NLC suffixes, how to read the assembly indentation, and what those cold-weather spec codes (A and B) mean. You get the serial number breaks: PC210-3KP K15001 and up, all the way through PC240NLC-3KP. No reprints, no generic aftermarket garbage.

388 Pages of Factory Part Numbers

You want to know how many pages cover the final drive vs. the engine? The catalog is 388 pages, figure numbers aren’t continuous, and each figure is a system breakdown. You get the part name, quantity per assembly, machine code, and the serial number range where that part applies. That lone paragraph in the foreword about the “.” and “..” indentation? That’s how you tell a component from a sub-component. Skip that and you order a seal kit when you needed the whole cylinder assembly.

How to Read the Parts List

Open the PDF to the foreword. The format is columnar: Fig. number, Description, Quantity, Serial number, Machine code, Codes. If you see a “.” in front of a part name, that part belongs to the assembly listed just above. Two dots mean it’s a sub-component of that assembly. The codes in parentheses – STD, LC, NLC – map to the model suffixes. For example, “-STD” corresponds to the PC240-6K base machine. The catalog uses these codes to tell you which parts interchange across the five models listed on the cover.

There is a reason the factory puts a little “KIT” note next to certain part numbers. Those items ship as a set, and the catalog lists the components under a KIT line. You will also see PAINT(1) and PAINT(2) markers for undercoat and different-color finishes. That matters when you need a bolt that matches the original corrosion protection – ask me how I know.

Cold Weather Specs: What the Codes Mean

Two cold-weather specifications appear in this catalog: (A) for -30°C and (B) for -50°C. These codes pop up beside parts like hydraulic hoses, seals, and battery cables. If you are working a machine that runs in northern Canada or a winter site in Minnesota, you need to order the (B) spec parts. The catalog tells you exactly which figure and line number those parts live on. Without this document, you are guessing which grade of rubber will crack at -40°F.

Order Parts the Right Way

When you call the Komatsu dealer, they will ask for the model number, the engine serial number, and the service meter reading. This catalog does not give you the engine serial number – that is on the machine tag – but it does give you the machine serial number ranges to confirm you are ordering for the correct production series. Use the figure number to reference the exploded diagram, then read the part number off the line that matches your machine code. If the line says “Part No.” with a superscript note, check the footnotes at the bottom of the page for supersession or interchange info.

Komatsu PC210-3KP Parts Catalog: Figure Numbers and Codes

Figure numbers in this catalog are not sequential. You might see Fig. 1-01 for the undercarriage and Fig. 3-12 for the swing mechanism. The table of contents at the front lists each figure with its page number. The codes next to each figure – like “STD” or “LC” – tell you which model variant that figure applies to. If a figure covers all models, it will say “STD/LC/NLC.” The catalog also uses “G-1, G-2” for part groups; those are assembly-level groupings that are not sold as individual parts.

One more thing about the interchange column. If you see a diagonal arrow between two part numbers, the top part is being replaced by the lower part. If there is a horizontal line with an asterisk, the part is supplied as a set rather than singly. The factory marks obsolete parts with a black dot. Do not waste time trying to order a part marked obsolete – order the supersession number listed directly below it.

Frequently Asked Questions

Does this parts catalog include wiring diagrams or torque specs?

No. This is a parts catalog only – it lists part numbers, quantities, codes, and interchange info. For torque specs and assembly procedures you need the service manual.

Why are there two different cold-weather codes, and how do I know which one my machine needs?

Code (A) indicates parts rated for -30°C ambient temperature, while code (B) is for -50°C. The catalog marks these codes in the “Codes” column next to the part number. If your machine was originally built for a specific region, check the serial number plate – if it says “COLD SPEC B” or similar, order everything with the (B) code. If you are unsure, call your Komatsu dealer with the machine serial number and ask which cold-weather package was installed. Using a (A) rated hose in a -50°C environment will crack that hose inside a week, and you will lose hydraulic oil on the jobsite.

Stop guessing which seal fits or whether a part supersedes. Access the Factory Manual and keep a PDF on your tablet while you tear down. You will stay on the machine, not on hold with a parts hotline.
