Komatsu PC200, PC220, 200LC-6, 220LC-6 1995 Workshop Manual

You’ve got a PC200-6 or PC220-6 on the lift, and the aftermarket PDF you obtained is missing half the torque specs. I’ve been there. That’s why I only trust the factory book. Komatsu PC200, PC220, 200LC-6, 220LC-6 1995 Workshop Manual is the same 729-page binder the dealer techs used when these machines were new. No reprints. No guesswork. Just the OEM data from Komatsu. This is the manual that tells you exactly how much to tighten that main pump relief valve and what the standard hydraulic pressure should read before you start tearing things apart.

PRUEBAS Y AJUSTES: What You Get on Page 20-1

The PRUEBAS Y AJUSTES section starts on page 20-1 and runs for dozens of pages. This is where you find the actual test procedures – measuring engine speed, exhaust color, valve clearance, compression pressure, leak-down, injection timing, and oil pressure. Every one of those procedures comes with a “TABLA DE JUICIO PARA VALORES ESTANDARD” – a judgment table listing acceptable ranges. If you’re dialing in the CLSS hydraulic system, page 20-1 is where you start. The manual also includes a full table of standard electrical system values, so you can check sensor outputs without guessing.

ESTRUCTURA Y FUNCIONAMIENTO: The CLSS System

Chapter 10, ESTRUCTURA Y FUNCIONAMIENTO, covers the CLSS (Closed-center Load Sensing System) in depth. There’s a system diagram and an operation description for each function. You’ll see how the main pump (HPV95=95) works with the control valve, the EPC solenoid valve, and the PPC valves for swing, travel, and service. The manual also walks through the relief valve settings and the safety suction valves. If you’ve ever had a machine that drifts or hesitates, this chapter shows you which valve to check and what pressure to expect.

Torque Specs and Fluid Capacities

Right in the PROLOGO section there’s a standard torque table (“TORSIÓN ESTÁNDAR”) and conversion tables. You get the correct ft-lb values for bolts and nuts used throughout the machine. The “LISTA DE LUBRICANTES Y AGUAS” in the GENERAL section tells you exactly what oil goes into the hydraulic tank, final drives, swing circle, and engine. No more guessing which ISO grade or SAE weight. For coolant, it lists the capacity in gallons. That table alone can save you an afternoon of flushing because you put in the wrong fluid.

Does This Manual Cover the Engine?

Yes, but with a specific caveat. The PC200-6 uses the S6D95L-1 engine; the PC220-6 uses the SA6D95L-1. This workshop manual covers engine-related parts in the structure section – fan belt tension adjustment (alternator and A/C compressor), governor linkage check, and speed sensor adjustment. For a full engine overhaul, Komatsu publishes a separate engine manual for the Series 95 motors. But for daily troubleshooting and adjustments on the machine, this manual has what you need. The wiring diagram and electrical circuit diagram in chapter 10 cover the entire machine, including the engine control system.

Why OEM Beats Aftermarket for This Komatsu

Aftermarket manuals for the PC200/PC220 often copy the Spanish text but leave out the safety warnings and tool lists. This factory manual includes “HERRAMIENTAS PARA COMPROBACIONES, AJUSTES Y LOCALIZACION DE FALLAS” – the specific Komatsu tool numbers for each test. You’ll also find the “MATERIALES DE RECUBRIMIENTO” list, telling you which sealants and adhesives to use on threads and gaskets. That kind of detail prevents leaks and comebacks. Next time you’re ordering parts, check the KOMATSU PC200 PC210 Hydraulic Excavator Parts Catalog for exploded views and part numbers to go with this manual.

For the PC200LC variant specifically, see the Komatsu PC200 PC200LC Workshop Manual. And if you’re working on a later model, the Komatsu PC200 PC220-7 Service Manual covers the -7 series updates. Reading a hydraulic schematic from this manual is more straightforward than a Manual Transmission rebuild diagram, because Komatsu labels every port and pressure tap. The structured troubleshooting approach beats any generic Manual Transmission guide – it’s designed for these exact machines.

Can I use this manual for a PC200LC-6?

Yes, it covers the 200LC-6 variant. The LC designation refers to the longer undercarriage; all other systems are identical to the PC200-6.

What if I don’t read Spanish?

The manual is written in Spanish, but the diagrams, torque tables, and numerical values are universal. Most sections have clear headings and numbered steps. If you’re comfortable using a parts catalog alongside, you’ll get through any repair. The electrical diagrams use standard ISO symbols. That said, if Spanish isn’t your language, consider having a bilingual coworker check the safety warnings on page 00-1 before you start. The “SEGURIDAD AVISOS DE SEGURIDAD” section contains critical precautions about jacking, welding, and high-pressure oil – these apply regardless of language.
