FIAT Kobelco CK850-II, CKE800, CKE700 Workshop Manual – 554 Pages of Factory Specs

You are staring at a machine that cost six figures and moves loads that can kill a man if one fitting backs off. The wrong torque on a hydraulic fitting or a missed step in the swing brake adjustment means downtime or worse. That is why you need the FIAT Kobelco CK850-II, CKE800, CKE700 Workshop Manual – not a reprint, not a third-party summary, but the actual 554-page OEM document that Kobelco issued for these crawler cranes. It is the same book that dealer techs used when these machines were new. I have seen too many guys lose billable hours because they trusted a generic spec sheet. This manual fixes that.

554 Pages of Factory Specs: What You Get

This is not a 50-page owner’s manual. The book is broken into ten major sections covering everything from the power train to the electric system. The table of contents alone runs three pages. Section 1 gives you the full specification for the CK850-II and the CKE800/CKE700 – performance numbers, outside dimensions, weight of each part, and stability calculations for swinging and traveling. Section 2 covers maintenance standards and test procedures, including pin and bushing wear limits, propel device specs, and the exact method of measuring pressure on page 2-17. That page alone can save you from chasing a phantom leak for half a day.

Torque Data That Matters: Metric and UNC Threads

Section 3 devotes 14 pages to tightening torque of capscrews and nuts. This is where aftermarket manuals fail. They give you a generic table and call it done. Kobelco lists metric coarse, metric fine, UNC coarse, UNF fine, and a separate table for hydraulic fittings. You need to know the difference between a 10.9 bolt and a 12.9 bolt? The conversion table on page 3-3 covers it. Hydraulic fittings are a different beast – one over-torqued JIC fitting can crack the flare. The manual gives you the foot-pound values for each size. I have used these numbers to reassemble pump drive assemblies more times than I can count. Use them.

Hydraulic System and Hoist Circuit: Real-World Application

Section 5 maps out the entire hydraulic system – location of main components, oil flow from all seven pumps, and valve details. If you are diagnosing a main winch that drifts under load, the hydraulic schematic in Section 6 shows you the brake cooling circuit and the freefall acceleration path. You can trace the oil flow from No. 4 and No. 5 pumps straight to the brake cooling circuit. Bleeding air from the brake circuit? That procedure is in Section 6.5. The manual does not assume you have a scan tool – it assumes you have a pressure gauge and a willingness to follow the diagram. The hoist system section (Section 7) covers the boom drum lock adjustment and the reduction unit. That is the kind of detail that keeps a crane from dropping a load.

One more thing about the electrical section. Section 10 has the full wiring schematic, a connector list, and the arrangement of electrical parts on the cab, deck, and revolving frame. If you have a no-start condition that you traced to a bad relay, the harness part number list helps you order the correct replacement. Want to see the actual component locations? The manual shows them on the left deck, right deck, and floor plate. No guesswork.

Who Needs This Manual?

This manual is for the guy who owns a CK850-II, CKE800, or CKE700 and does his own repairs. It is also for the independent heavy equipment mechanic who needs factory data to quote a job correctly. The audience is not the weekend warrior with a lawn tractor – these are 50-ton crawler cranes. If you are comfortable reading hydraulic schematics and using a torque wrench, you will get value from page 1 (the cover) to page 554. The manual covers the power divider disassembly (Section 4.3), the swing bearing (Section 8.4), and the propel reduction unit (Section 9.3). For fleet managers, having this PDF on a tablet means your techs work from the same data as the dealer.

OEM vs. Aftermarket: Why Kobelco’s Own Print Wins

I have been burned by aftermarket manuals that copied the wrong torque table or left out the safety warnings. This manual starts with a SAFETY section before any spec. It warns about stability limits and pressure tests. The document is scanned from the original Kobelco print, not a re-typed version. The unit conversion tables in Section 3.3 – millimeter to inch, meter to foot, gradient conversion – are all factory-verified. You will not find a field with a missing value. The book code S5GG00005ZE04 tells you this is the fourth revision. That means updates were incorporated. If you buy the Kobelco CK850-II Technical Manual from a third party, you are gambling. This is the original.

For those who need the electrical schematics separate, check the FIAT Kobelco CKE600, CKE700, CK800, CK850-2, CK1000-2 Electrical Schematic. And if you are working on the excavator variants, the FIAT Kobelco SK330NLC-6E SK330LC-6E Workshop Manual – 1244-Page OEM is also in the series. As for external references, you can look up the basics of a Manual Transmission on Wikipedia, but the manual covers the power train far better than any general resource. Same for the Manual Transmission – the book goes into the propel system, which is a different animal.

Does this manual cover the engine rebuild for the CK850-II?

Yes, Section 4.2 covers engine removal, repair, and re-installation. It does not list every internal clearance, but it gives the steps and references to the separate engine service manual for internal specs. The manual is a chassis-level workshop manual, not an engine overhaul manual.

What format is the manual in?

PDF. 554 pages, searchable. You can access it immediately after purchase.

Can I print the pages I need?

Yes. The PDF is not locked. Print a page for the torque specs and take it to the shop. I have a grease-stained copy of page 2-17 on my bench right now.

Will this manual help me fix a swing brake that won’t hold?

Yes. Section 8.2 covers the swing system hydraulic schematic and stopping function. The swing lock adjustment is in Section 8.5. Follow the pressure test procedure on page 2-19 to check the swing brake valve. That is the exact method used by Kobelco technicians.

You have a machine that needs factory-accurate data. This manual is the only way to get it without a dealer visit. Access the Factory Manual and keep it on your tablet or printed out. Every torque value, every hydraulic circuit, every adjustment procedure is here. No reprints, no third-party guesses. Just 554 pages of Kobelco engineering.
