10.5 Spare parts

CAUTIOn

Use of unsuitable spare parts.

Spare parts which do not comply with the requirements as laid down by Bosch
Rexroth can cause injury and property damage.

▶

Use exclusively original spare parts from Rexroth to repair the Rexroth axial
piston units, otherwise the functional reliability of the axial piston unit cannot
be assured and the warranty is void.

The spare parts lists for axial piston units are order-specific. When ordering spare
parts, quote the material and serial number of the axial piston unit as well as the
material numbers of the spare parts.
Address all questions regarding spare parts to your responsible Bosch Rexroth Service
partner or the service department of the manufacturer's plant for the axial piston unit.
Details for the manufacturer's plant can be found on the name plate of the axial
piston unit.
