Komatsu PW160-7E0 2007 Workshop Manual

I’m Mike Callahan, 28-year ASE Master. I’ve torqued more head bolts than most people have had hot meals, and I’ve seen more machines wrecked by guys trusting aftermarket spec sheets than by actual wear. This Komatsu PW160-7E0 2007 Workshop Manual is the real deal – factory-issued, 1140 pages, straight from the people who built the machine. If you’re working on a PW160-7E0 with serial H55051 and up, this is the only document you should have on your bench.

1140 Pages of Factory Specs

Page count matters. When you’re buried in a hydraulic pump rebuild or a swing motor overhaul, you don’t want a 50-page “quick guide.” This manual gives you the full structure, function, and adjustment data for every major system. The Fuel system section alone covers pressure testing, bleeding procedures, and residual pressure release. The Engine chapter includes compression pressures, valve clearance adjustments, and blow-by measurements. Every spec is the one Komatsu used on the line.

Fuel System and Engine Related Parts

Look at the TOC: “FUEL, COOLANT AND LUBRICANTS” under 01 GENERAL. Then flip to “ENGINE RELATED PARTS” in section 10. That’s where you’ll find the radiator, oil cooler, and charge air cooler layouts. The manual also covers the SAA4D107E-1 engine (for complete engine tear-down, you’ll need the separate 107 Series Engine Shop Manual, but this book gives you the machine-specific mounting and interface details). Need to bleed air from the fuel circuit? The procedure is in the Testing and Adjusting section – and it’s not the generic “crack the injector lines” advice you get from YouTube. It’s the exact sequence Komatsu expects.

Does This Manual Cover the Hydraulic Circuits?

Yes, and it does it right. Section 10 has a full hydraulic circuit diagram, CLSS (Closed Center Load Sensing System) outline, and detailed breakdowns of the control valve, swing motor, travel motor, and pilot pressure control system. The HPV125 pump is covered with LS valve, PC valve, and LS(pc)-EPC valve functions. The manual doesn’t assume you know the system – it explains the operation of the swing lock, the relief valve portion, and the travel motor’s counterbalance spool action. If you’ve ever chased a drift in the boom circuit, the BOOM SAFETY VALVE section will save you hours of head-scratching.

Swing Motor and Travel Motor: What You Need to Know

Two common failure points. The manual dedicates separate subsections to each. For the swing motor, you get the operation of the swing lock, the relief valve portion, and the full operation sequence. The travel motor section includes the “OPERATION OF TRAVEL MOTOR” and the overrun protection logic. Pay attention to the “2 Position 3 way valve” and “2 Position 4 way valve” diagrams in the solenoid valve manifold section – those are critical for diagnosing intermittent travel issues. I’ve had techs skip those schematics and end up swapping a motor that was fine. The manual also covers the ATT EPC valve assembly and the quick coupler control valve if your machine is equipped.

Testing and Adjusting: Standard Value Tables

Section 20 is where the real work gets done. It starts with “STANDARD VALUE TABLE FOR ENGINE RELATED PARTS” and “STANDARD VALUE TABLE FOR CHASSIS RELATED PARTS.” You’ll find flow control characteristics for the PC valve, measuring procedures for engine speed, intake air pressure (boost), exhaust gas color, valve clearance, compression pressure, blow-by, oil pressure, and fuel system diagnostics. The manual also includes the inspection and adjustment of hydraulic oil pressure in the work equipment, swing, and travel circuits. Don’t skip the “Procedure for pressure reducing adjustment” – that’s a step most aftermarket manuals leave out.

Source Authenticity: OEM vs Aftermarket

Aftermarket manuals are copies of copies. They reprint somebody else’s table, often with wrong torque values or missing notes. This one is a direct scan of the Komatsu factory document, VEBM395100. The copyright is 2007, printed in Europe. The caution statements are intact – like the Never connect to NC as malfunctions and errors occur warnings on the engine controller connectors (CN-CE01, CN-CE02, CN-CE03). A third-party reprint would have lost those details. You’re paying for the original, not a guess.

Does this manual include the engine overhaul procedure?

It covers engine-related parts, fuel system, and testing procedures like valve clearance and compression. But the SAA4D107E-1 engine is documented in a separate 107 Series Engine Shop Manual. This manual tells you what you need for the machine integration – mounting, cooling, fuel delivery – and points you to the engine-specific manual for internal rebuilds. That’s the correct factory approach.
