Komatsu PC600-PC700LC Installation Manual – OEM Field Assembly Specs

Description

If you’re staring at a disassembled Komatsu PC600, PC600LC, PC650, PC650LC, or PC700LC on a jobsite in San Antonio, you’ve got one shot to get the installation right. I’ve seen too many guys skip the factory sequence and end up with a hydraulic leak that costs a day of billable hours. This Komatsu PC600, PC600LC, PC650, PC650LC, PC700LC Installation Manual is the binder you keep next to the coffee pot. 211 pages of OEM assembly instructions — no aftermarket reprints, no guesswork.

Tightening Torque: The Specs That Matter

Torque is not a suggestion. The dedicated TIGHTENING TORQUE section in this manual lists every fastener spec for these excavators. Page 1 of the instruction covers the field assembly header, but the torque data lives in its own chapter. Aftermarket manuals love to generalize — this one gives you the exact ft-lb for track frame bolts, counterweight mounts, and boom cylinder pins. Don’t guess and risk a stripped hole on a $12,000 component.

What Does the Installation Manual Cover?

Everything from unpacking the KIT LAYOUT DIAGRAM to the final Field Assembly Inspection Report. You get chapters on PRECAUTIONS FOR FIELD ASSEMBLY, DISPOSAL OF REMOVED PARTS, and a full LIST OF TOOLS FOR FIELD ASSEMBLING. The manual splits the job into sections: A (Chassis), B (Work Equipment for backhoe), C (Loading Shovel work equipment), and D (Counterweight Remover). Section M covers inspection and maintenance after assembly — including flushing the hydraulic circuit and checking failure codes.

Chassis Assembly Step-by-Step

Section A runs 17 sub-steps: left and right track frame installation, travel pipe, operator cab handrails, rearview mirrors, counterweight mounting, and bleeding air from travel motors. Each step references the required tools from the LIST OF TOOLS FOR FIELD ASSEMBLING. You also get track shoe tension test procedures and a check of fuel, coolant, and oil levels. This is not a generic guide — it’s written for the specific model and serial numbers 65001 and up.

Work Equipment Assembly: Backhoe and Loading Shovel

Two separate procedures for two configurations. Section B covers boom, arm, bucket cylinder assembly for backhoe — includes hose routing, grease piping, and wiring connections. Section C does the same for loading shovel: releasing residual hydraulic pressure, pulling out boom foot pins, installing bucket assembly, and bleeding air from the work equipment circuit. If you mix up the sequence, you’ll be fighting pressure locks all afternoon. Stick to the factory order.

211 Pages of OEM Assembly Data

The manual weighs in at 211 pages, each one printed from the original Komatsu PDF — not a photocopy of a photocopy. You get the COATING MATERIALS chart, SELECTION OF WIRE ROPES, and the exact TIGHTENING TORQUE table. Compare that to a third-party summary that skips the shim adjustment for counterweight (Section D-2). This document is the one your insurance adjuster will ask for if something goes wrong. Keep it in the truck.

Source Authenticity: OEM vs Aftermarket

I’ve used aftermarket manuals that claimed “factory specs” and then gave me a torque value off by 15 ft-lb on a boom cylinder pin. That’s a lawsuit waiting to happen. This is the original Komatsu Field Assembly Instruction, document number GEN00101-02, published for the PC600-8E0, PC600LC-8E0, PC650-8E0, PC650LC-8E0, and PC700LC-8E0. It includes the PRECAUTIONS FOR FIELD ASSEMBLY that cover safety meetings, crane signals, and protective gear. You don’t get that from a scanned aftermarket PDF.

Does this manual include wiring diagrams or electrical schematics?

No. It focuses on mechanical assembly, torque, and hydraulic circuit procedures. Wiring connections are limited to work equipment wiring (B-13) and rear view camera (A-10).

What is the most common mistake when using this manual?

Skipping the PRECAUTIONS FOR FIELD ASSEMBLY section. Guys jump straight to the first bolt and miss the tool list and safety meeting requirements. I’ve seen this cause dropped counterweights and hydraulic oil baths. Read page 3 (CONTENTS) first, then the precautions. The manual is structured so you don’t skip steps — but you have to open the damn thing. Access the Factory Manual and print the TIGHTENING TORQUE page for your toolbox.

You need a manual that tells you the truth about torque and sequence. This one does. It’s 211 pages of Komatsu factory procedure, not a rewrite from a guy who never touched a PC700LC. Get it in your hands, read Section M before you start the hydraulic flush, and don’t let anyone tell you aftermarket is good enough. Access the Factory Manual.
