FIAT Kobelco CKE900, CKE600, CK1350, CKE1800, CKE2500-2 Hydraulic Schematic – 32-Page Factory Diagram

Description

I’ve seen guys spend two hours chasing a hydraulic leak on a CKE900 because they were following a copied diagram from some forum. The pressure readings didn’t match, the lines didn’t match, and they ended up replacing a good pump. That’s the difference between a factory schematic and some scanned reprint. This FIAT Kobelco CKE900, CKE600, CK1350, CKE1800, CKE2500-2 Hydraulic Schematic is the actual OEM document — 32 pages of what the factory put in the machine. Not a redraw. Not a translation. If you need to trace a circuit, identify a valve symbol, or decode an abbreviation like PB J or DR7, this is what you reference on the bench.

Hydraulic Symbols and Abbreviations from the Factory

Page 1 of the manual starts with a symbol table. Swivel joints, double-acting cylinders with cushion, pilot lines, variable displacement pumps — every icon is drawn the way FIAT Kobelco intended. The abbreviation table on page 3 lists all codes used in the CK/CKE/BM/BME series circuits. For example, ACC means Accumulator, PBA means Parking Brake Aux. Winch. You get the exact same legend the dealership uses. No guessing what a dashed line means.

CKE600, CKE900, CK1350, CKE1800, CKE2500-2 – Which Models Are Covered?

The abbreviation table on page 3 has columns for CKE600, CKE900, CK1350, CKE1800, CKE2500-2, plus a few others like CKE700 and CKE800. Each abbreviation shows which models use that port. For instance, D R5 Drain Propel motor (RH/LH) appears on CKE600, CKE900, CK1350, CKE1800, CKE2500-2, but not on CKE700. If you’re working on a CKE1800 and see a D R5 line, you know it’s a propel motor drain. That kind of precision saves hours of cross-referencing.

Why OEM Schematics Outmatch Aftermarket Versions

Aftermarket hydraulic diagrams often omit the abbreviation key. They’ll draw a line labeled “PB J” with no explanation. This manual includes the full list from AC to PR — 200+ abbreviations across four pages. The schematic itself is the actual factory layout, not a redrawn copy where someone misread a symbol. If you’ve ever tried to use a third-party manual for a FIAT Kobelco and found the wrong cylinder orientation, you understand the value. Pair this with a full workshop manual like the KOBELCO CK1000-II CKE900 Workshop Manual and you have a complete diagnostic setup.

Using the Abbreviation Table to Diagnose Hydraulic Circuits

Let’s say you’re troubleshooting a boom-down issue on a CKE2500-2. The schematic shows a line labeled “PD B”. The abbreviation table confirms PD B = Pressure for Boom Down. That line routes from the control valve to the cylinder. If you lose pressure there, you know exactly which circuit to test — not the main winch or the aux clutch. The table also tells you which models share that port. For the CK1350, PD B is present; for the CKE600, it’s also there. The manual covers all five primary models in one document. For broader CK/CKE series hydraulic diagrams, refer to the Kobelco CK/CKE Series Hydraulic Circuit Diagram for additional model variants.

What This 32-Page Manual Does NOT Cover

This is a hydraulic schematic, not a service manual. You won’t find torque specs, engine rebuild procedures, or electrical wiring diagrams. What you get are 32 pages of crisp line drawings and the factory’s own symbol set. If you need a service manual for the CKE1350 or CK1600 alongside this schematic, the KOBELCO CK1600 CKE1350 Shop Manual is a solid companion. Also, if you’re refreshing your understanding of Hydraulic systems fundamentals, that helps, but this schematic cuts through the guesswork. For cylinder repair specifics, Cylinder Head Mechanics can supplement what the schematic shows for port routing.

Frequently Asked Questions

Does this manual include torque values?

No. This is strictly a hydraulic schematic — symbols and line routing only.

Can I use this for the CKE700 model?

The abbreviation table includes a column for CKE700, but the schematic itself is drawn for the listed models (CKE600, CKE900, CK1350, CKE1800, CKE2500-2). Most symbols and abbreviations apply cross‑model, but for a dedicated CKE700 diagram you would need the specific schematic.

What do abbreviations like AC C and P/S mean?

They are listed in the abbreviation table on pages 3 and 4. AC C stands for Accumulator, P/S stands for Pressure Switch. The table gives the full abbreviation key so you can decode every label in the circuit without having to guess or search online.

Is this a printed book or a digital access?

It’s a digital PDF, 32 pages. You can access it and view on a tablet or print it out for the shop.

Stop tracing blind or relying on blurry copies. Open the factory schematic, find the circuit you need, and get it right the first time. Access the Factory Manual and keep it open on your tablet next to the machine.
