New Holland Kobelco CKE1350, CK1600 2004 Workshop Manual

If you’re a tech who’s been burned by aftermarket manuals with missing torque specs or generic hydraulic drawings, you already know the cost. I’ve seen guys spend half a shift chasing a swing brake issue because some third-party manual skipped the pilot pressure sequence. Not here. This New Holland Kobelco CKE1350, CK1600 2004 Workshop Manual is a factory-original 15-page PDF that covers only the swing system — no fluff, no generic diagrams, no guesswork. It’s the same booklet your dealer’s senior tech uses when the swing motor won’t release.

This manual came off the press in June 2004, book code S5GN1502E. It applies to CKE1350 machines GN02-01001 up and CK1600 machines GN02-01006 up. If you’re working on either model, you need these exact pages.

Swing System: What the Factory Manual Covers

Five chapters, 15 pages, zero overlap with the rest of the machine. That means no wading through engine or undercarriage sections to find the swing data. The factory split the swing system into: Apparatus and Location Components, Construction and Function (including the hydraulic schematic), Swing Reduction Unit, Swing Bearing, and Swing Lock. Each chapter has its own page numbering (1-1, 2-1, etc.), so you can jump straight to the problem area.

Apparatus and Location Components

Page 1-1 lays out every major component: swing pump mounted on the power divider, swing motor with internal brake, swing control valve, reduction unit, swing bearing ring, swivel joint, swing gear, and swing lock. If you’re replacing a swing motor or chasing a leak, start here. The illustration (Fig.1-1) shows exactly where the oil cooler and slewing ring sit. No guessing which line goes where.

Construction and Function: Hydraulic Schematic and Swing Operation

Section 2 is the meat of this manual. The hydraulic schematic on page 2-1 shows the full circuit from boom to auxiliary actuator, including the T/P (opt) port. Then pages 2-2 through 2-6 walk through two specific swing modes: Neutral Free and Neutral Brake. The factory explains how the swing remote control valve, brake mode select solenoid valve (SOL46), and the pilot pressure from the control pump release the brake and meter oil to the swing motor. If your machine drifts in free mode or locks up in brake mode, you need to understand spool A and B sequencing. It’s all here.

3 Key Sections You Need for Swing Repairs

Beyond the theory, three sections matter for actual wrenching: the Swing Reduction Unit (section 3), the Swing Bearing (section 4), and the Swing Lock (section 5). These are the mechanical parts that wear. The reduction unit section tells you the gear ratio and how the unit mounts to the motor. The swing bearing section covers the bolting pattern and inspection points. Swing lock section covers the pin and cylinder — critical for safety when you’re working under the upper structure.

Does This Manual Cover the Full Machine?

No. This is a subsystem manual. It covers only the swing system. If you need the engine, hydraulics outside the swing circuit, or the undercarriage, you’ll need other factory manuals. For the full parts breakdown, see the Kobelco CKE1350 Parts Manual 2006. For understanding the symbols in the hydraulic schematic, grab the Kobelco Hydraulic System Schematic Symbols & Abbreviations. And for operation, inspection intervals, and fluid specs, the Kobelco CK1600 Operation & Maintenance Manual covers both models.

Why Factory OEM Documentation Matters

I’ve seen third-party swing manuals with the wrong internal brake release pressure. One guy ended up pulling a motor because the aftermarket spec said 200 psi when the factory calls for 450 psi. This manual comes straight from New Holland Kobelco — it’s the exact same PDF the dealer sends to his shop. No redrawn diagrams, no paraphrased torque values. The hydraulic schematic on page 2-1 is the real deal. If you’re troubleshooting a slow swing or a dragging brake, this is the reference you bring to the machine, not a six-page generic you printed off a forum.

Get the Right Torque Data

This manual does not include a dedicated torque table, but the swing bearing section gives bolt sizes and tightening sequence references. For the swing reduction unit mounting bolts, you’ll find the spec in the component assembly section. If you need general fastener torque for the machine, look at the Manual Transmission documentation for transmission-related torque patterns (though swing is hydraulic, not mechanical transmission). For the swivel joint bolts, check the Manual Transmission resources only if cross-referencing similar threaded fasteners — but honestly, stick with the factory manual for any swing-related fastener.

Frequently Asked Questions

Does this manual cover the full excavator?

No. It covers only the swing system. 15 pages, swing only. You’ll need separate manuals for engine, hydraulics, tracks, etc.

What year models does this apply to?

2004. The first edition was issued June 2004. The machine serial numbers are GN02-01001 and up (CKE1350) and GN02-01006 and up (CK1600). Later revisions may exist, but this is the original factory release.

Can I print this manual and take it to the field?

Yes. The PDF is clean, clear, and designed for printing. The schematics are high enough resolution to read hose routing. I’d recommend laminating the hydraulic schematic page (2-1) if you use it around hydraulic oil.

Does it include torque specifications for the swing bearing bolts?

The swing bearing section references the tightening pattern and thread size, but does not list a numerical torque value on a dedicated page. You’ll need the matching Kobelco CKE1350 Parts Manual 2006 for the official torque table. Many OEM manuals split torque data into the parts manual, so this is not unusual. If you need the bolt torque right now, call your dealer with the machine serial and ask for the swing bearing bolt spec — they’ll pull it from the same source this manual came from.

Bottom line: if you’re rebuilding the swing system on a CKE1350 or CK1600, this is the document that keeps you from pulling the wrong part or torquing something to the wrong spec. 15 pages, factory diagrams, hydraulic waveforms, and a clear breakdown of the swing modes. Access the Factory Manual and get the swing sorted before the next job goes off the rails.
