Liebherr L550, L580, L556, L566, L576 2010 Service Manual

If you’re turning wrenches on a Liebherr L550, L580, L556, L566, L576 2010 Service Manual is what you need. I’ve seen guys snap bolts because some third-party paper said 150 ft-lbs when the factory spec was 120. That’s not a mistake you forget. This is the actual OEM document from Liebherr-Werk Bischofshofen, printed in 2010, covering the 2plus2 wheel loader series.

Safety Regulations and Special Tools – First Chapter

Chapter 1 opens with safety regulations you follow on every job. It also lists the special tools required for maintenance and repairs. Page 2 in the preface tells you exactly what basic tool set you need plus the Liebherr-specific tools. Overlooking this section gets you hurt or costs you a torn seal.

Technical Data Overview – Know Your Machine

The technical data covers the whole machine and each individual assembly. You get engine specs, hydraulic pressures, transmission ratios, and axle capacities. For charge pressure values, turn to the technical data section. That data is not generic – it’s measured from the actual production line. I’ve run into dealers who rely on memory and misdiagnose a pump because they guessed the flow rate. Don’t be that guy.

Maintenance Schedule and Lubrication Charts

Chapter 2 transitions into maintenance. You get the inspection schedule, testing and adjustment checklists, lubrication charts, and fuel/lubricant specifications. Every grease point is mapped. The schedule lists intervals in operating hours. If you skip a lube point on the L580, the center pin wears and then you’re pulling the whole boom. The manual saves that headache.

Period.

15 Function Groups – Engine, Hydraulics, Drivetrain

The technical description is broken into fifteen function groups. Each group explains layout, function, and technical data of components. For example, Group 4 covers the engine cooling system; Group 7 is the hydraulic system with pump flow and relief settings. The drivetrain section details the ZF transmission, and you’ll find a reference to the Manual Transmission internals if you need a refresher on gear operation. Not every manufacturer organizes their manual this way. Liebherr does it right.

Troubleshooting and Service Code Table

Chapter 19 is your diagnostics hub. It includes troubleshooting procedures, a service code table, and a description of the “SCULI” service software. When the dash lights up with a code, you don’t guess – you look it up in this chapter. The manual tells you which sensor, which wiring path, and which test point. Aftermarket manuals leave that out. This one doesn’t.

752 Pages of Factory Data

That number matters. 752 pages means every system has room for diagrams, torque tables, and step-by-step removal/installation procedures. You’ll find torque values for cylinder bolts, wheel lug nuts, and driveline fasteners. The hydraulic system pressures are listed in psi and bar. No rounding up to make it easier – these are the numbers the factory floor uses.

Why OEM Documentation Beats Aftermarket

Aftermarket manuals reprint specs from a different year or combine models and hope it works. This Service Manual is specific to the L550, L556, L566, L576, and L580 with production numbers 456, 454, 460, 457, 459 and serial numbers listed on the ID page. If you own a machine from the 2010 series, the data matches your exact hardware. The wiring diagrams are original factory prints, not traced from a photograph. You trace a wire and the color code is right.

Does This Manual Include Full Wiring Diagrams?

Yes. The function group chapters include electrical schematics for each system. Starting, charging, ECM, lighting, and implement controls are all covered. For a detailed look at how a Manual Transmission syncs electrically with the ECU, the drivetrain section has that diagram.

Does this manual cover the 2010 L550 specifically?

Yes. The manual is titled for the 2010 model year and includes the L550, L556, L566, L576, and L580 in the 2plus2 series. The production numbers and serial numbers are listed on the ID page. If your machine’s serial falls within the listed range, the data is direct.

Can I find torque specs for the wheel lug nuts?

Torque tables are in the technical data section and the maintenance chapter. Look for the wheel assembly subsection. Always use a calibrated torque wrench – the manual states the spec.
