FIAT Kobelco SK 100 V, SK 120 V, SK 120LC V Workshop Manual

You have a FIAT Kobelco SK 100 V, SK 120 V, or SK 120LC V hydraulic excavator in the bay. Customer wants it back by Friday. You pull up a copied PDF from some random site and find torque specs that don’t match any bolt you’ve ever seen. That’s the problem aftermarket reprints create. This 712-page workshop manual is the OEM document — the same book the dealer techs use. FIAT Kobelco SK 100 V, SK 120 V, SK 120LC V Workshop Manual starts with the factory spec sheet and never lets up.

712 Pages of Factory Data – Not a Condensed Reprint

This manual is 712 pages of factory-issued information. It is divided into four major sections: General, Systems, Components, and Procedure. The General section includes specification LP01, location and weight of components LP03, maintenance standards and test procedures LP04, working standards LP07, and the standard man-hour table LP08. You get everything from fluid capacities to hydraulic pump flow rates. The Systems section covers LP12 Hydraulic System, LP22 Control System, LP15 Swing Frame, LP18 Travel System, LP25 Electrical System, LP26 Air-Conditioner System, LP21 Attachments, and LP29 Troubleshooting. Aftermarket copies often skip the LP08 man-hour table and the detailed troubleshooting steps. Not this one.

LP04 Maintenance Standards and Test Procedures

If you are overhauling a swing motor or checking wear limits on the hydraulic cylinder, LP04 is where you live. It includes test procedures for pressure checks, flow rates, and component clearance limits. The factory specifies how to measure each item and what the acceptable range is. No vague statements like “inspect and replace if worn” — you get actual numbers. For example, the wear limits on pin bosses and bushings are listed with tolerances. This section alone saves you from calling the dealer for every spec.

Safety Warning on Page 2 – Read It Before You Lift a Component

Page 2 of this manual has a warning that every tech should read before cracking a bolt. It states: “Because of the size of some of the machine components, the serviceman or mechanic should check the weights noted in this Manual. Use proper lifting procedures when removing any components.” The weight data is in LP03. A misjudged counterweight or boom section can kill you. The manual doesn’t assume you know safe lifting — it spells it out. That is the kind of detail that gets cut from reprints. Don’t skip it.

Does This Manual Cover the Electro-Hydraulic Control System?

Yes. LP22 Control System covers the pilot pressure circuits, joystick controls, and the main control valve. If the machine is sluggish on the swing or the hoe drifts, the LP29 Troubleshooting section walks you through the hydraulic and electrical checks. The manual also includes LP25 Electrical System with wiring diagrams. You get the factory schematic, not a re-drawn mess. Whether it’s a solenoid issue or a failed relief valve, the manual directs you to the right component chapter.

FIAT Kobelco SK 100 V Workshop Manual – Engine and Component Disassembly

The Components section is laid out by part number. Chapter 50 covers the engine — disassembly, inspection, reassembly. Chapter 12 covers the hydraulic pump, 13 the control valve, 14 other valves, 15 hydraulic motor, 16 swivel joint, 17 hydraulic cylinder, and 21 reduction unit. Each chapter includes torque values for bolts and fasteners. The manual states: “When checking or repairing the machine we suggest that you refer to this manual carefully.” That is not a suggestion — it’s a time-saver. You do not need to hunt down a separate engine manual or pump manual.

Why the Factory Manual Beats Aftermarket Copies

Aftermarket vendors scan old prints and lose clarity on torque charts and wiring diagrams. This file is from the original OEM PDF — the same as the dealer’s. The manual even warns on page 1: “Take special care to order parts only after confirming the validity of the part number in the ‘PARTS MANUAL’.” That means the part numbers in this workshop manual are verified against the factory parts list. You also get the book code S5LP0007E1.

How many pages does this manual have?

712 pages.

What is covered in LP04 Maintenance Standards and Test Procedures?

LP04 includes wear limits for pins, bushings, and bores, along with hydraulic test procedures for pump flow, relief valve pressure, and cylinder leakage. It also covers torque specifications for bolts in ft-lbs (converted from Nm in the factory data). The manual gives you step-by-step inspection criteria, not just a table. You also get the test conditions – oil temperature, engine speed, and required gauges. This section is critical for any rebuild job. If you skip the LP04 procedures, you risk installing worn parts and doing the job twice. Most aftermarket manuals condense this into a single page. Not this one.

Does this manual cover the transmission system?

This excavator uses hydraulic travel motors and reduction units – there is no manual transmission. For background on manual transmissions in other equipment, see Manual Transmission and Manual Transmission.

What sections cover the electrical system?

LP25 Electrical System provides full wiring diagrams, connector pin-outs, and component location data. It covers the starter circuit, alternator, sensors, and the machine’s control modules. The manual also includes troubleshooting steps for common electrical faults. For the air conditioner, LP26 Air-Conditioner System has separate wiring and test procedures.
