Komatsu PC200, PC200LC, PC210, PC210LC Parts Catalog – Factory OEM

You have a Komatsu PC200 or PC210 series machine torn down and need a water temperature sensor part number. Or you’re staring at a hydraulic line that leaked and you don’t know which O-ring to order. Aftermarket parts catalogs will give you a number that might fit, but you end up with the wrong thread pitch or a seal that swells shut on the first hot cycle. This is the OEM Komatsu PC200, PC200LC, PC210, PC210LC Parts Catalog – 505 pages, factory-sourced, and ordered exactly like the dealer’s system. No translations that lose critical dimensions. No guesswork on serial number breaks.

I’ve been turning wrenches since before most of these excavators left the factory. When a customer rolls in with a PC200LC-7 that won’t build pilot pressure, I don’t reach for a third-party website. I pull this catalog, find the main pump connection parts section, and cross-reference the part number against the machine serial number. Saves a phone call to the dealer and a two-day wait for the wrong box.

Engine Overhaul: Cylinder Head to Flywheel

This catalog covers the engine section with every part from the cylinder head gasket set down to the flywheel bolts. If you’re rebuilding the SAA6D107E-1, you need the correct part numbers for the turbocharger oil tube, the injector nozzles, and the crankshaft damper. The index breaks it down: cylinder head, valve train, timing gears, oil pump, cooling fan. You see the part number, the quantity per machine, and the exact illustration reference. No ambiguity on whether the PC210 takes a different water pump than the PC200 – it tells you right there in the FIG. No. and the serial number applicability column.

Ever ordered a main bearing set only to find it doesn’t fit your block because of a mid-production change? This catalog lists the serial number breaks explicitly. Page 2 gives you the machine serial number ranges (PC200-7: DBB0001- , PC210LC-7: DBG0001-). That is how you know which parts apply to your specific undercarriage.

Hydraulic System Breakdown: Valves, Pumps, and Lines

The hydraulic section runs deep: main control valve, piston pump, suction and return lines, boom and arm circuits, and all the optional attachment piping. Need a seal kit for the main relief valve set at 280 kg/cm²? The parts catalog lists each relief valve as a separate item with its own part number. The LS (load sensing) line routing is illustrated with each tube and fitting identified. If you’re adding a second auxiliary circuit, the optional equipment pages show the valve stack, the solenoid valves, and the accumulator bracket. That is information you will not find in any aftermarket document.

Pay attention to the “Symbols and codes” section starting on page 3. Komatsu uses marks like “●” and “△” to indicate interchangeable or superseded parts. If a part is discontinued, the catalog shows which newer part replaces it. That saves you from ordering obsolete numbers.

Electrical and Cooling Systems: Factory Wiring and Coolant Routing

Battery cables, main harness clips, alternator internal parts (35A and 60A versions), starter motor breakdowns (4.5kW and 5.5kW), and all the warning labels are listed. The cooling section covers radiator, intercooler, condenser, fan shroud options – both with and without AC. If your machine has the optional sound suppression package, the fan shroud part number changes. This catalog separates those variations. You can order the correct radiator hose without guessing which side the thermostat housing faces.

Working on a machine with electrical gremlins? The wiring harness is broken down into sub-sections: starter harness, main harness with clamps, battery box wiring. Each connector and clip has a part number. That is the kind of detail that gets a machine back to digging in one afternoon instead of three.

Why This Factory Parts Catalog Beats Aftermarket

Every aftermarket parts catalog I have seen for Komatsu excavators either reprints blurred scans or substitutes generic part numbers that require you to call a hotline. This is the original OEM PDF from Komatsu, in Chinese and English, with clear illustrations and the exact part numbers the dealer computer spits out. The “Parts Book” title on page 1 confirms it. The foreword explains how to read the figure-and-list layout. No assumptions. No “equivalent to” nonsense. If you want to learn about the engine itself, refer to this Wikipedia article on diesel engines for background on common rail systems, but for ordering parts, you need this catalog. Alternatively, this Wikipedia article on diesel engines covers general theory. Neither replaces the part numbers here.

Who Needs This Catalog: Field Mechanics and Equipment Owners

If you own a PC200LC-7 or PC210LC-7 and do any of your own repairs, you need this. If you run a shop that services these models, you need one per bay. The 505 pages cover engine, cooling, fuel tank, electrical, hydraulic, turntable, cab, guards, and swing bearing sections. We also carry the matching workshop manual for torque specs and procedures – check out the Komatsu PC200 PC200LC Workshop Manual if you need repair procedures. For a deeper dive into the full machine teardown, the Komatsu PC200 PC220 Service Manual – 810 Page OEM Shop Manual is a solid companion. And if you need operator-level instructions like daily checks and controls, grab the Komatsu PC200 PC200LC PC210 PC210LC PC220 Operators Manual – 283 Pages.

Does this catalog include torque specs and repair procedures?

No. This is a parts catalog only – it lists part numbers, quantities, and exploded diagrams. For torque values and step-by-step repair instructions, you need the workshop manual.

How do I find the right part for my machine if the serial number is not listed?

Each section has a “SERIAL No.” column that tells you the machine serial number range for that part. If your machine serial number falls within the range shown on the page, that part is correct. If your serial number is newer than the last listed range, check the “Symbols and codes” at the beginning of the catalog – a triangle symbol often indicates a superseded part that replaces an earlier one. For machines outside the covered series (e.g., PC200-6), this catalog does not apply. You need the specific manual for your model. The foreword on page 2 explains the figure numbering and interchangeability symbols in detail. Read it before you start ordering. It takes five minutes and saves you from returning a $400 hydraulic pump.

Stop wasting billable hours chasing wrong part numbers. This is the exact reference Komatsu dealers use. Access the Factory Manual and keep it on your shop tablet or printed out. Have the part numbers before you call the parts counter.
