Komatsu PC160LC-8 2007 Workshop Manual

You’ve been burned by aftermarket manuals before. I have too. The specs are wrong, the wiring diagrams don’t match, and you end up chasing ghosts. That stops with the factory-issued Komatsu PC160LC-8 2007 Workshop Manual. This is the exact document Komatsu put together for their technicians. 1015 pages of verified data. No third-party reinterpretation. If you’re working on a PC160LC-8 with serial number C20001 and up, this is the only source you should trust.

Specifications and Technical Data

Section 01 of this manual lays out the full machine specs. You get dimension drawings, weight tables, and the approved fuel, coolant, and lubricants. No guessing which oil grade – it’s all there in black and white. The weight table is critical for transport and lift planning. Don’t skip it.

What the Troubleshooting Section Covers

The troubleshooting portion is massive. It’s divided into failure code tables, fuse locations, and then four parts of troubleshooting by failure code. On top of that, there are dedicated sections for electrical system (E-mode), hydraulic and mechanical (H-mode), and engine (S-mode). If you’re getting a code on the monitor, you go to Section 40 and find the exact diagnostic path. No guesswork.

7 Major Systems in the Structure Section

Section 10 breaks down the machine into seven systems: engine and cooling, power train, undercarriage, hydraulics (three parts), work equipment, cab, and electrical. Each system includes function descriptions and maintenance standards. For example, the power train section covers the swing circle, swing machinery, final drive, and sprocket. You get the factory wear limits and inspection intervals.

Get Factory Torque Specs from the Standard Tightening Torque Table

Right in the foreword, there’s a standard tightening torque table. This isn’t a generic chart – it’s Komatsu’s own values for bolts and nuts on this machine. Use those numbers. I’ve seen too many guys grab a generic torque chart and snap a bolt in the final drive. Don’t be that guy.

Engine and Cooling System: Disassembly Procedure

Section 50 covers disassembly and assembly. The engine and cooling system subsection gives you the step order for pulling the radiator, oil cooler, aftercooler, and fuel cooler. There are required tool lists and safety warnings about hot coolant. Follow the sequence – Komatsu arranged it so you don’t create clearance issues.

Original Komatsu Documentation, Not a Reprint

This is a PDF of the actual shop manual, not a scanned copy of a copy. The page quality is clear, the diagrams are sharp. Aftermarket manuals often skip the safety notices and the handling instructions for connectors and hydraulic components. This one has all of it: safety notice, how to read electric wire codes, precautions for push-pull couplers. That’s the difference between doing the job right and doing it twice.

Frequently Asked Questions

Can I use this manual for a PC160LC-8 with a different serial number range?

It’s officially for C20001 and up. If yours is earlier, some specs may differ. Check your machine serial before relying on values.

Does the manual include the hydraulic circuit diagram?

Yes. Section 90 has the full hydraulic circuit diagram and electrical diagrams. You can trace lines and troubleshoot pressure issues.

What kind of torque values are listed – metric or imperial?

The manual includes a conversion table in the foreword. The standard torque table is in Nm, but you can convert. For field work, I’d use the Nm numbers directly.

How are the troubleshooting procedures organized?

They start with failure codes, then E-mode, H-mode, S-mode. Each mode has a step-by-step check. For example, if you have a code from the hydraulic system, you go to H-mode and follow the decision tree. It’s logical once you understand the numbering – but read the foreword first for how to read the manual. That’s a mistake many skip.
