Komatsu WH609-1E0, WH613-1E0, WH713-1E0, WH714H-1E0, WH716-1E0 Workshop Manual

You’ve been burned by aftermarket manuals that pull torque values out of thin air. I’ve seen stripped threads and blown gaskets from trusting those. This Komatsu WH609-1E0, WH613-1E0, WH713-1E0, WH714H-1E0, WH716-1E0 Workshop Manual is the real deal – 496 pages of OEM data straight from Komatsu. No guesses. No third-party editing. If you’re working on one of these machines, you need the actual specs the factory uses on the line.

Structure and Function: 17 Systems Broken Down

Section 10 of this manual covers every major system on these telescopic handlers. From the ENGINE-TRANSMISSION COUPLING through the POWER TRAIN, TRANSMISSION, FRONT AXLE, REAR AXLE, and BRAKE PUMPS. You get full hydraulic diagrams, solenoid valve layouts, safety valves, cylinders, and the air conditioning system. If you need to understand how the 4WS steering unit interacts with the control valve, it’s all here. This isn’t a generic overview – this is Komatsu’s internal documentation.

Testing and Adjustments: Valve Lash and Brake Pedal Travel

Section 20 starts with STANDARD SPECIFICATIONS and goes straight into VALVE LASH ADJUSTMENT. Checking engine speed? Tensioning the A/C compressor belt? Adjusting accelerator cable length? It’s in there. Adjusting brake pedal travel and positioning the stop lamp microswitches is covered on a specific procedure. Bleeding air from circuits before hydraulic pressure checks. You’ll also find calibration steps for the overturn prevention system (ASM). Don’t skip the transmission assembly pressure checks – that’s how you catch a failing seal before it costs you a shift.

Does the Manual Cover the WH714H-1E0 Transmission?

Yes. All five models – WH609-1E0, WH613-1E0, WH713-1E0, WH714H-1E0, WH716-1E0 – are included. The TRANSMISSION section covers power shift checks, assembly pressure checks, and speed checks of the cardan shafts. If you’re diagnosing a slipping clutch or delayed engagement, you need the factory procedure for checking dynamic pump DP value and calibrating the DR valve.

30 Removal and Installation Procedures

This section is 200+ pages of how to pull it apart and put it back together. Starts with special tools and precautions. Covers engine hood, radiator hood, air filter, turbocharger, exhaust pipe, belt and fan, radiator-exchanger assembly, intercooler, muffler, battery tray, cylinder head, injectors, injection pump, hydraulic pump, complete engine-transmission assembly, control valve, solenoid valves, A/C compressor, servo-control feed valve, steering solenoid valve, front and rear axles, telescopic boom, lift and offset cylinders, intermediate and top boom, extension cylinder, and boom sliding pads replacement. Each removal and installation is a separate subsection – no guessing what goes where.

Torque Specs: Why the Factory Standard Matters

Aftermarket manuals often hand-wave torque values. This manual includes a dedicated STANDARD TIGHTENING TORQUE table right after the safety section. Every bolt on the machine has a specified torque. When you’re torquing the cylinder head or the brake pump mounting bolts, you need that number. If you don’t have it, you’re either undertightening (leaks) or overtightening (stripped threads). Also includes a COATING MATERIALS table and TABLE OF OIL AND COOLANT QUANTITIES. Get the factory data.

I’ve been turning wrenches for 28 years. When I see a tech reach for an aftermarket PDF, I tell them to stop. Those reprints copy errors. This manual is a direct scan from Komatsu’s own shop manual – verified, complete, with the original file name and all 496 pages. If you think a generic guide saves you time, wait until you have to redo a job because the torque was wrong.

FAQ

What models does this manual cover?

WH609-1E0, WH613-1E0, WH713-1E0, WH714H-1E0, WH716-1E0. Five telescopic handler models.

Is this a reprint or an original factory scan?

This is a direct digital reproduction of the official Komatsu Shop Manual. No third-party editing. The PDF includes the original file name and all pages. We do not reprint or modify content. It’s the same document a Komatsu dealer tech would use. Every page is exactly as Komatsu released it, including the revised pages table, safety warnings, and torque tables. If you’ve ever been burned by a “reprint” that omitted crucial pages or mislabeled diagrams, you’ll appreciate the difference.

Does it include torque specifications for the engine?

Yes. Section “STANDARD TIGHTENING TORQUE” at the front gives baseline values. Additionally, specific torque values are called out in procedures like cylinder head installation.

How many pages?

496 pages.

Stop guessing. Access the Factory Manual and get the torque right.
