FIAT Kobelco SK170LC-6ES, SK170-6E Workshop Manual

If you’re working on a FIAT Kobelco SK170LC-6ES or SK170-6E, you need the real factory book. Not a reprint, not a third-party compilation. This is the FIAT Kobelco SK170LC-6ES, SK170-6E Workshop Manual – 986 pages of OEM data that came straight from Kobelco’s engineering department. I’ve been turning wrenches for 28 years and I can tell you the difference between a factory spec and an aftermarket guess is the difference between a machine that runs and one that leaks oil for a week. That’s not hyperbole.

986 Pages of OEM-Sourced Information

The manual is exactly what you’d get if you walked into a Kobelco dealer and asked for the shop binder. It covers the SK170LC-6ES and SK170-6E models specifically. Not a range, not a ‘similar’ machine. These pages are organized into seven major sections: SPECIFICATIONS, MAINTENANCE, SYSTEM, DISASSEMBLY, TROUBLESHOOTING, ENGINE, and INSTALLATION PROCEDURES FOR OPTIONAL ATTACHMENT. That’s 986 pages of nothing but this machine.

Engine Section: Disassembly and Troubleshooting

Inside the ENGINE section (YM51) you get the factory removal order, torque values for the head bolts, and the correct sequence. The TROUBLESHOOTING section (YM44) covers engine diagnosis separately. I’ve seen guys skip the troubleshooting flow and replace a fuel pump that was fine because they didn’t check the supply pressure first. This manual gives you the test procedure. Page 3 has the safety warnings—read those before you stick your hand anywhere near a rotating shaft.

What Torque Values Are in the SPECIFICATIONS Section?

Section one, SPECIFICATIONS, includes a TOOLS subsection (YM11). That’s where you find the required tool list and the torque tables. You want to know the proper torque for the swing motor mounting bolts? It’s in there. The manual uses Imperial units—foot-pounds, inch-pounds, psi. No metric conversion guesswork needed if you’re in North America. The MAINTENANCE section (YM12) gives you the standard maintenance time schedule, so you know how often to check fluid levels and replace filters. Use the factory intervals; skip that and you’ll be replacing bearings in a season. For a larger excavator, consider the FIAT Kobelco SK330NLC-6E SK330LC-6E Workshop Manual – 1244-Page OEM for additional reference.

Understand the Electrical System Before You Probe It

Moving to the SYSTEM section, it has a full ELECTRICAL SUBSECTION (YM23). Wiring diagrams, connector pinouts, voltage readings at each sensor. If you short a wire because you used a generic diagram, you’re looking at a fried ECU. This manual gives you the correct wire colors and locations. Also includes the MECHATRO CONTROL SYSTEM (YM21) which is the electronic brain for the hydraulics. You need the factory procedure to calibrate it after a valve replacement. The FIAT Kobelco SK330, SK330LCVI, SK330NLCVI Workshop Manual – 1302 Pages Factory S covers that series if you have a 330 chassis in the shop. Understanding the clutch pack in a Manual Transmission helps when diagnosing the swing brake on the SK170.

Installation Procedures for Optional Attachments

Finally, the last section covers mounting breakers and nibblers (YM63). If you’re adding a hydraulic breaker to an SK170LC-6ES, the manual tells you the required bracket modifications and hydraulic line routing. No guessing. You get the factory-approved installation steps. Need specs for the SK310? The FIAT Kobelco SK310, SK310LC Workshop Manual | 350 Pages is available separately. For a refresher on how a Manual Transmission works, the theory applies to the travel drive.

Use the factory data. Nothing else works.

Is this a genuine OEM manual?

Yes, it’s the factory Kobelco document, not a reprint.

What if I need help with the MECHATRO control system diagnostics?

The TROUBLESHOOTING section has a dedicated MECHATRO CONTROL subsection (YM41) that walks you through error codes, sensor tests, and actuator checks. It includes the control override procedures—for example, if the ESX control locks you out, the manual tells you the safe way to bypass it for testing. Without this, you’re either guessing or calling a dealer tech who charges $150 an hour. The manual pays for itself the first time you use it.
