FIAT Kobelco CK1600, CKE1350 2004 Service Manual

If you’ve ever wasted a Saturday wrestling a backhoe loader apart with a third-party manual that gave you a pin clearance tolerance that was off by 0.010”, you know the feeling. That’s the kind of shop time you don’t get back. This FIAT Kobelco CK1600, CKE1350 2004 Service Manual is the factory-issued book code S5GN0402E, printed in 2004, and it’s the same 24 pages the dealer techs used. No reprints, no copy-paste from a different model. Every dimension in this thing was checked against production drawings.

What the Manual Covers: Maintenance Standards and Test Procedures

The table of contents splits into two main sections. Section 1 – Maintenance Standard – covers pin, bushing, spring, and sheave wear limits, plus the propel device. Section 2 – Performance Standard and Test Procedure – gives you operating speed specs, the point and method of measuring pressure, and the slew ring inspection. You won’t find exploded views of the engine or wiring diagrams here; this manual is for the undercarriage, the driveline, and the hydraulics that make a backhoe actually move and swing.

Check Pin and Bushing Wear Limits

Page 1-1 has a table that lists every pin and bushing on the machine – front drum, rear drum, boom drum, boom foot, brake pedal. For example, the front and rear drum pin part number GG82W01008P1 has a standard diameter of 1.732” (44.0 mm) and a usable limit of 1.725” (43.82 mm). That’s 0.007” of wear before you replace the pin. The bushing inner diameter goes from 1.732” to 1.743” (44.26 mm). If you try to reuse worn parts because an aftermarket manual told you a looser limit, you’ll get slop in the drum engagement and premature failure. This manual gives you the exact number.

Propel Device: What the Factory Specs Tell You

Section 1.2 covers the propel device. The manual doesn’t include full disassembly steps – it’s a maintenance standard, meaning it tells you what to measure. You’ll find free length specs for compression and tension springs. The front and rear drum pawl spring (part HP26C15002G1) has a standard free length of 2.835” (72 mm) and a usable limit of 2.693” (68.4 mm). A spring that’s sagged more than 0.142” will not return the pawl positively. That’s the kind of threshold that stops a machine from shifting.

Measuring Hydraulic Pressure Correctly

Section 2.2 is the point and method of measuring pressure. Page 2-2 describes the locations for pressure taps and the procedure to check charge pressure, pilot pressure, and main relief. You need a pressure gauge with the right range – the manual specifies which port to connect to and at what engine speed. Follow these steps and you won’t blow a seal because you assumed the relief was set lower than it is. The OEM procedure includes a warning about high-pressure oil and hot components. Listen to that warning.

Slew Ring Inspection Protocol

Section 2.3 covers the slewing ring (the bearing that lets the upper structure rotate). The manual gives you the standard dimension for the ring gear and the usable limit for backlash. You measure it with a dial indicator at the specified point, and if the reading exceeds the limit, the ring and pinion need replacement. Page 2-6 has the table. I’ve seen shops skip this check and end up with a cracked ring because they didn’t catch the wear early. Don’t be that shop.

Why Use the Factory Service Manual?

Aftermarket manuals for this era of Kobelco equipment are hit-or-miss. This is a direct scan of the factory shop manual, with the OEM book code and revision date. No guesswork about which part number supersedes which – the table on page 2 lists the applicable machine serial numbers: CKE1350 from GN02-01001, CK1600 from GN02-01006. If your machine falls in those ranges, this manual is correct. If it doesn’t, check the related KOBELCO CK1600 CKE1350 Shop Manual for other editions. You can also cross-reference with the Kobelco CK1600 Technical Manual for deeper component disassembly, or the Kobelco CK1600 2007 Operation & Maintenance Manual for daily service intervals. For background on how these hydraulics systems compare to Manual Transmission drivetrains, the same engineering principles apply.

Frequently Asked Questions

Does this manual include engine repair procedures?

No. This is specific to the undercarriage, propel device, and hydraulic test procedures. For engine overhaul, you need the separate engine service manual.

Can I use these pressure test specs on a CKE1350 that has been modified with a different pump?

The specs in this manual are for the original Kobelco hydraulic system as delivered from the factory. If the machine has been retrofitted with an aftermarket pump or valve block, the OEM pressure settings may not apply. You’ll need to contact the component manufacturer for their recommended settings. That said, using the factory pressure test procedure still gives you a baseline to compare against. For example, the main relief pressure tap location and the method of measuring are standard regardless of pump brand – the key is that the relief valve itself might have a different cracking pressure. I always recommend verifying with the pump supplier before adjusting anything. The manual’s test procedure steps for gauge connection and engine speed are still valid, but the target pressures in section 2.2 are for original equipment. When in doubt, install a pressure gauge and run the machine through its cycles – the readings will tell you if something is off.

If you’re working on a CK1600 or CKE1350, you need the factory numbers. Manual Transmission builders use OEM torque specs for the same reason: precision matters. Access the Factory Manual now and get the 24 pages that keep your backhoe loader running to spec.
