Installation 29/60
RE 91616-01-B/10.2014, A6VE Series 65 and 71, Bosch Rexroth AG
7.4 Installing the axial piston unit
7.4.1 Preparation
1. Compare the material number and designation (ordering code) with the details in
the order confirmation.
If the material number for the axial piston unit does not correspond to the one in
the order confirmation, contact Bosch Rexroth Service for clarification, see
chapter 10.5 “Spare parts” on page 49.
2. Before installing, completely empty the axial piston unit to prevent mixing with
the hydraulic fluid used in the machine/system.

The direction of rotation as specified on the name plate determines the direction
of rotation of the axial piston unit as viewed on the drive shaft, see chapter 5.3
“Product identification” on page 20.
7.4.2 Dimensions
The installation drawing contains the dimensions for all connections and ports on
the axial piston unit. Also observe the manuals provided by the manufacturers of the
other hydraulic components when selecting the required tools.
7.4.3 General notes
Please keep in mind the following general notes for installation of the axial piston
unit:
• Note that you can expect certain installation positions to affect the control
device. Gravity, dead weight and case pressure can cause minor shifts in control
characteristic curves and changes in response time.
• For combinations comprising several units, make sure that the respective case
pressure is not exceeded. In the event of pressure differences at the reservoir
ports of the units, the shared drain line must be changed so that the minimum
permissible case pressure of all connected units is not exceeded in any situation.
If this is not possible, separate drain lines must be laid if necessary.
