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.
ADJUSTMENT PROCEDURE – CHECKING AND ADJUSTING THE TRAVEL HYDRAULICS

1.1 Please note that during the warranty period only authorized LIEBHERR representatives are permitted to work on the wheel loader valves. This includes adjustment.
1.2 The valves must be checked and adjusted with the hydraulic oil at operating temperature of 60° + 10°C (140° F).
1.3 Use glycerine filled pressure gauges with an accuracy of ± 1 % . 1.4 If specified values cannot be reached, the cause must be determined according to the troubleshooting chart, and the defect must be repaired.
1.5 To check and adjust the following valves, check if the inching device on regulator valve 32 is in neutral position. See section 10.72.
1.6 After the valves have been adjusted, install new safety caps. This will prevent unauthorized personnel from attempting to adjust the valves.
