FIAT Kobelco CK1000-II, CKE900 Workshop Manual – What the Factory Gave the Techs

Ever tried splitting a 100-ton crawler crane with nothing but a generic online PDF and a prayer? I’ve seen guys lose a whole day because the aftermarket torque chart had the wrong thread pitch for a hydraulic fitting. That’s why you reach for a real FIAT Kobelco CK1000-II, CKE900 Workshop Manual – the one the Kobelco factory printed for their own techs. This thing is 564 pages of what the engineers actually want you to do, not what some internet forum guessed.

What You Get from a 564-Page Shop Manual

This isn’t a quick-reference card. It’s divided into ten sections, starting with full SPECIFICATION chapters for both the CK1000-II and the CKE900. You get outside dimensions, weight breakdowns for each part, and even stability calculations for swinging and traveling. Skip that on a crane and you’re asking for trouble. Then MAINTENANCE STANDARDS (Section 2) gives you pin, bushing, spring, and sheave wear limits plus the operating speed and pressure test points. The GENERAL WORK STANDARD section (Section 3) is where you live – it has the tightening torque tables for metric coarse, metric fine, UNC, UNF, and hydraulic fittings. No guessing whether that bolt is Grade 8 or Grade 10.9 – it’s all right there.

Torque Specs That Match the Factory Floor

Section 3.1 is the part I dog-ear first. You get torque values for capscrews and nuts in both metric and inch threads. For example, the hydraulic fitting torque table (3.1.5) lists every fitting size used on the machine. One wrong ugga-dugga on a boom cylinder line and you’re pulling a fitting out of the port. That’s not a repair – that’s a new valve block. The manual also covers standard parts like bolts, O-rings, back-up rings, and bite fittings (3.2.1–3.2.4). Need conversion tables? Section 3.3 has unit conversion, millimeter-to-inch, meter-to-foot, and gradient tables. You can convert a metric spec to inches without opening a separate app.

Hydraulic System: Seven Pumps and the Oil Flow Paths

Chapter 5 is the heart of the machine: HYDRAULIC SYSTEM. It shows you the location of main components, then walks through the hydraulic circuit and component specs. The oil flow from No.1 and No.2 pumps, then No.3 pump, then No.4 and No.5 for the main and auxiliary winch drum brake cooling circuit, No.6 pump (control), and No.7 pump for auxiliary actuator circuit. That’s seven separate circuits in one machine. If you lose pressure on the boom hoist, you need to know which pump feeds it. The manual gives you the schematic and the pressure test procedure. Combine that with the performance test procedure in Section 2.2.2, and you can diagnose a weak pump in the Manual Transmission’>manual time it takes to hook up a gauge.

Who Needs a Manual This Thick?

If you own a CK1000-II or CKE900, you need it. If you run a rental yard or a construction company with one of these crawler cranes, you need it. The Manual Transmission’>manual covers the power train (engine removal, pump drive assembly disassembly), the hoist system (boom hoist, drum lock adjustment, brake pedal bleeding – Section 6.6 is critical for air in the brake circuit), the swing system, the propel system, and the electric system with wiring schematics and connector lists. Beginners? Don’t dive into a crane without factory guidance. But if you have a basic toolbox and can read a torque table, this book will keep you out of trouble. Professionals will appreciate the page on upper and lower roller and axle adapter tightening torque in Section 9.5 – that’s a spec you won’t find in any aftermarket reprint.

Source Validity: OEM vs. Aftermarket Documentation

This is a direct scan of the Kobelco shop manual – book code S5GH00002ZE04. It was issued from 2006 to 2007 with revision ZE01 through ZE04 for the CK1000-II (from GH03-02004 onward) and CKE900 (from GH03-02002 onward). That means it’s the final factory update. Aftermarket manuals cut corners – they re-type tables and introduce typos. This is a Manual Transmission’>manual you can print, put on the bench, and trust. The safety section alone is reason enough – crane work kills people who ignore load charts and torque specs. Don’t gamble with a third-party PDF when the factory version is available.

Does this manual cover the CK1000-II and CKE900 exactly the same?

Yes. Both models are included in the same document. Sections 1.1 and 1.2 list separate specifications for each, including performance, dimensions, and stability. The rest of the manual applies to both machines unless noted otherwise.

Are the torque specs in imperial units?

Section 3.1 gives torque in both metric (Nm) and inch-pound (in-lb) and foot-pound (ft-lb) for UNC and UNF threads. The conversion tables in Section 3.3 let you swap between systems.

I need the hydraulic circuit diagram. Where is it?

Section 5.2.1 has the hydraulic circuit schematic. The oil flow descriptions from each pump are in section 5.3.3 through 5.3.7. You’ll need that when tracing a leak or checking pressure.

What about the electrical system – does this include wiring diagrams?

Yes. Chapter 10 (ELECTRIC SYSTEM) has the wiring schematic (10.1), connector list (10.2), and arrangement of electrical parts for the cab, right deck, floor plate, revolving frame, left deck, and left guard. Harness part numbers are listed in 10.3.7.

You can spend your weekend chasing a ghost pressure drop, or you can get the factory documentation that tells you which valve feeds which circuit. This is the same 564-page manual that Kobelco sent to dealers. Access the Factory Manual now, print the torque tables, and keep your crane in the air where it belongs.
