Komatsu WD600-6 Installation Manual – Factory Assembly Specs for Field Technicians

If you’re putting together a WD600-6 wheel dozer from a shipping crate, you need the factory manual. Not a third-party reprint. Not a scanned copy from some forum. The Komatsu WD600-6 Installation Manual is exactly what Komatsu issued for serial numbers 55001 and up. 69 pages. Each step numbered. Each torque spec listed. That’s what you work from.

Komatsu WD600-6 Installation Manual: What the 69 Pages Cover

The manual begins with a block outline and dimension table – you check your clearances before you start lifting. Then it walks through workspace layout, general assembly schedule, and a full list of equipment, jigs, tools, and consumables (section 5 and 6). The real meat is section 7 – the assembly procedure. That’s 52 pages of numbered steps from oil/coolant filling to running-in.

Does the Manual Cover the Brake and Cooling Systems?

Yes. See items 0065 and 0066. Brake pipe connection is a separate step – both standard and Brake cooling specification. You get the exact routing and torque for those lines. If you’re working on a machine with the cooling option, you follow item 0066. Miss that step and you’ll have a leak at the cooler. I’ve seen it.

6 Key Assembly Sections You Must Follow

The manual is ordered like a production line: front axle, drive shaft, brake pipes, tires, cab installation (multiple steps for AJSS and steering wheel specs), cab harnesses, ducts, lights, fenders, ladder, handrails, then checking sections, bleeding hydraulic and brake air, starting engine, H-link and Y-link, blade assembly, greasing, electrical system failure history deletion, floor mats, running-in, and final touch-up. That sequence exists because each step depends on the previous one – for example, you cannot install the cab until the front axle and brake pipes are connected and secured. The brake pipe routing also differs based on whether your machine has the cooling option; item 0066 covers the cooling specification separately. Skipping the check of sections (item 0310) before starting engine is asking for a hydraulic leak or a loose fastener that ruins a bearing. The electrical system failure deletion procedure (items 0430, 0510, 0520) must be done in order, and you need the dummy harness from section 5 – not your own jumper wires. I’ve seen a tech try to shortcut the deletion and brick the controller. Follow the manual.

Get the Right Torque Specs from the Factory

Aftermarket manuals guess. This one gives you the Komatsu-approved torque values for every critical fastener: brake pipe fittings, axle mounting bolts, drive shaft flanges, cab mounts, blade links. You don’t have to wonder. You also get fluid capacities for oil and coolant (item 0020). Torque values are listed inline in each step. You’ll see them for brake pipe connections on page 14 and for brake bleeding on page 48. Verify with your own torque wrench – don’t assume anything.

Tool List and Consumables from Section 5

Section 5 lists every jig, tool, and consumable you need before you start. That includes special tools like the dummy harness for electrical system failure deletion (item 0590). Section 6 covers oils, greases, and paints – including the specific grease for the pins and the paint for touch-up after assembly. Having this list means one trip to the parts counter, not five.

You can pair this manual with the full Komatsu WD600-6 Workshop Manual – 1859 pages OEM for deeper repair coverage. For other dozer models, see Komatsu WD900-3 Installation Manual – Field Assembly Specs & OEM Torque and Komatsu WF550A-3 Installation Manual – OEM Factory Assembly Specs.

Understanding the drivetrain helps too – read up on Manual Transmission basics if you’re new to wheel dozers. Also check Manual Transmission for gearbox principles.

FAQ

Is this manual the same as the service manual?

No, this is only for field assembly – not diagnostics or overhaul.

Does it cover the electrical system failure deletion procedure?

Yes – items 0430, 0510, 0520 cover deleting electrical system failure history in 3 steps. You need the starter kit (dummy harness) mentioned in section 5. Without that harness, you cannot clear the codes properly. The manual walks you through the exact procedure, including how to connect the dummy harness and which signals to cancel. This is critical for a machine that has been shipped with the battery disconnected – the controller logs faults that must be cleared before first operation. Follow the sequence or the machine will not start.
