FIAT Kobelco CK2500-II, CKE2500-II Workshop Manual

You’re staring at a crawler crane that won’t swing, the hydraulic schematic on your tablet is from a third-party site, and the torque values don’t match anything you’ve ever seen. I’ve been there. That’s why I won’t touch a FIAT Kobelco CK2500-II, CKE2500-II Workshop Manual unless it’s the factory print. This one runs 608 pages and comes straight from Kobelco’s book code S5JD00002ZE03. No aftermarket guesswork.

Specification Chapters for the CK2500-II and CKE2500-II

Section 1 breaks down the specs for both models—performance, outside dimensions, weights of base machine, counterweight, and attachments. You get stability data for swinging and traveling. Need the inch-pound conversions? The manual includes millimeter-inch and meter-foot tables in Section 3.3. That’s the kind of detail that keeps you from ordering the wrong sheave or pin.

What Torque Specs Does This Manual Cover?

Section 3.1 has the tightening torque for capscrews and nuts—metric coarse, metric fine, UNC, UNF, plus hydraulic fittings. Page 3-3 gives you the numbers for M6 through M30 coarse threads. You don’t look those up in a generic chart. This is the factory spec for these machines. I’ve seen stripped bolt holes from guys using a standard torque table. Don’t be that guy.

Understand the Hydraulic Circuit Before Service

Chapter 5 maps the entire hydraulic system. Component locations, circuit diagrams, and oil flow from each of the six pumps. It explains the No.1 and No.2 pump flow, then the No.3 and No.4 pump flow, then the control pump (No.5) and auxiliary actuator circuit (No.6). When a swing motor starts lagging, you trace it back through these schematics, not some aftermarket redraw. If you’re serious about keeping your KOBELCO CK2500-II CKE2500-II Shop Manual handy on the bench, this is the section you’ll dog-ear first.

Hoist System: Lifting a Load Safely

Section 6.2 walks you through lifting, holding, and lowering a load—powered lowering and free-fall operation. The drum lock adjustment procedure is right there, along with the brake pedal adjustment and air bleeding steps. You don’t experiment with hoist brakes. You follow the exact assembly drawings for the winch reduction unit, with or without free fall option. That’s how you keep the load where it belongs.

6 Pump Circuits Explained

Within the hydraulic system chapter, the oil flow from all six pumps is described in detail. Each subsection covers a specific pump circuit, including control pressures and valve operations. Knowing which pump feeds the boom hoist versus the swing system saves hours of diagnosis. This manual lays it out better than any training video I’ve seen.

Electrical System Wiring Schematics

Chapter 10 gives you the complete electrical wiring schematic, a connector list, and the arrangement of electrical parts. No vague diagrams—factory color codes and pin locations. You want to diagnose a no-start or a faulty swing lock solenoid? Start here. For general background on tractor-style Manual Transmission systems, the power train section in Chapter 4 covers the pump drive assembly and engine removal, but the specific transmission used in these cranes is detailed in the propel system (Chapter 9). If you’re also working on other Kobelco equipment, check the Kobelco CK2500-II Crawler Crane Specifications for machine data and the Kobelco CK2500-II Operators Manual for daily operation. The same external resource on Manual Transmission fundamentals can help if you’re cross-training.

Tool List and Work Standards

Section 3.2 covers standard parts—bolts, O-rings, back-up rings, and bite fittings. You’ll see the exact dimensions and part numbers. The conversion tables in 3.3 let you switch between metric and Imperial on the fly. I keep a printout of those tables laminated in my toolbox. That’s the kind of real-world utility you get from this manual.

FAQ

Is this the same as a service manual?

Yes. “Workshop Manual” and “Service Manual” are interchangeable in this context. It’s the full factory document for repairs, not a simplified owner’s manual.

Does it cover both CK2500-II and CKE2500-II?

The manual includes separate specification sections for each model. Both have their own performance data, dimensions, and stability tables.

What about the electrical system?

Chapter 10 provides the full wiring schematic, connector list, and component arrangement. This is the OEM diagram used by dealer techs. It shows wire colors, connector pinouts, and component locations. If you’re troubleshooting a swing lock solenoid or a failed ECM, this is your primary resource. You won’t find a generic version that matches these exact circuits.

Can I print this PDF?

The 608-page file is fully printable. No restrictions. Take sections into the shop as needed.

If you’re working on one of these cranes, don’t waste time on aftermarket copies. Access the Factory Manual and get the specs that matter for your CK2500-II or CKE2500-II.
