FIAT Kobelco CKE900, CKE600, CKE800, CKE700, CK850-2 Technical Manual

If you’re tracing a hydraulic circuit on a FIAT Kobelco backhoe loader and you don’t have the factory symbol legend, you’re guessing. I’ve seen whole control valve assemblies swapped because someone misread a cross-port relief symbol from an aftermarket chart. This 30-page Technical Manual gives you the exact symbols and abbreviation tables used on the CKE900, CKE600, CKE700, CKE800, and CK850-2 models. No guesswork, no third-party invention — just the OEM data you need to read the diagram right the first time.

Hydraulic Schematic Symbols Reference

Pages 1 and 2 of this manual contain the full symbol roster: swivel joints, telescopic cylinders, variable displacement pumps, counterbalance valves, sequence valves, and the rest. Every symbol used in the CK/CKE/BM/BME series diagrams is listed with its name. You won’t find a generic “hydraulic motor” icon here — you get the specific symbol for a variable displacement motor and a double rotate pump and motor. That level of precision matters when you’re ordering a replacement or building a test line.

Which Models Are Covered?

This manual covers the CKE600, CKE700, CKE800, CK850-2, and CKE900. The abbreviation table on page 3 includes model columns for each — for example, CKE800 and CK850-2 share most drain port labels but differ on swing control drains. If you’re working on a CKE900, you’ll see which auxiliary winch options apply. No need to cross-reference a dozen separate documents; it’s all in these 30 pages.

30 Pages of Factory Data

Thirty pages might not sound like much — until you’re staring at a tangled mess of hoses and you need to identify which port is DR3 vs DR5. The manual abbreviates every line: ACC for accumulator, MCC for main clutch cooling, PDB for pressure boom down. Those abbreviations are model-specific; the table on page 3 shows which apply to your CKE700 versus the CKE900. Get the wrong one and you’ll be capping off a pressure port that should be open.

Use the Abbreviation Table Correctly

Take PD M 2 — pressure for main winch down 2nd speed. On the CKE900 that port exists; on the CKE600 it’s blank. The table makes that obvious. Ignore the model columns and you’ll waste time chasing a line that doesn’t exist on your machine. I’ve watched a tech put a T-fitting into a PDB port that wasn’t even drilled on his CKE800 because he used a generic schematic. This manual prevents that.

CKE900 vs CK850-2: Key Differences

One example: DR4 Drain Swing motor is present on the CKE600, CKE700, CKE800, and CK850-2, but on the CKE900 that drain is labeled DR4 for Propel motor (RH/LH). Different function, same abbreviation — but the model column tells you which is which. That’s the kind of detail aftermarket reprints ignore. You need the original FIAT Kobelco layout.

Pair This With a Workshop Manual for Complete Repairs

This technical manual is the dictionary for the hydraulic circuit. For actual disassembly and torque procedures, you’ll want the KOBELCO CK1000-II CKE900 Workshop Manual”>KOBELCO CK1000-II CKE900 Workshop Manual. The two together let you read the diagram and then turn the wrench with the right specs. Also check the Kobelco CK/CKE Series Hydraulic Circuit Diagram”>Kobelco CK/CKE Series Hydraulic Circuit Diagram for full system layouts. For older models, the KOBELCO CK850-II CKE800 CKE700 Shop Manual”>KOBELCO CK850-II CKE800 CKE700 Shop Manual covers the mechanical side.

Hydraulic motors in these machines often drive a Manual Transmission”>Manual Transmission on the propel side — the symbol for the motor is on page 1. Understanding that symbol matters when you’re diagnosing a no-drive condition. Likewise, the clutch symbols tie into the Manual Transmission”>Manual Transmission cooling circuits. Skip the symbol reference and you’ll miss the link between the motor drain and the transmission case.

Can I use this manual to rebuild the engine?

No.

How do I identify which abbreviation applies to my specific machine model?

Open page 3 and look for the column headers: each of the 30 abbreviation rows has checkmarks for CKE600, CKE700, CKE800, CK850-2, CKE900, and others (CK1350, CK1000-2, etc.). If the cell is blank, that abbreviation does not exist on your model. Also note the “Remark” column — it tells you if a port varies by option. For example, PD1 (Boom/Jib Pedal control) only appears on CKE1350. Use those columns to filter exactly which lines run on your chassis.
