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.

Instructions on regular care and maintenance is excluded from this manual since they are covered in the individual
Operations and Maintenance Manuals.

Observe all Accident Prevention Guidelines before any maintenance and repair on the wheel loader. To perform repairs listed in this manual, a complete set of standard tools as well as special tools and fixtures shown and listed in this manual are necessary. It is essential to keep all equipments, tools and working areas clean and tidy.

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.
