This manual has been issued to provide you with technical information on design, function, disassembly, assembly, adjustments and troubleshooting of components and assemblies on the LIEBHERR wheel loader.

The descriptions are brief but precise, with photographs, drawings, electric and hydraulic circuit schematics and graphic diagrams. This information is intended to simplify any necessary repair work on the LIEBHERR wheel loader.
We deliberately avoided full photographic details of each repair stage, since only skilled mechanics, already familiar with most repair work, should perform these repairs. This manual also contains information about adjustments and adjustment values.

No special emphasis is put on replacing sealing components such as 0-rings, gaskets etc., since it is taken for granted that all removed seals, 0-rings and gaskets are replaced during the course of repair. Unless specific values are given, all threaded connections should be tightened according to the torque charts.
