Installation 29/60
RE 92701-01-B/04.2018, A10VO, A10VSO Series 31,
Bosch Rexroth AG
If the minimum fluid level is equal to or below the upper edge of the pump,
see section 7.3.3 “Above-reservoir installation” on page 30.
Axial piston units with electric components (e.g. electric controls, sensors) must
not be installed in a reservoir below the fluid level.
Our advice is to fit a suction pipe to the suction port
S
and to fit a pipe to case
drain port
l
or
l
1
. In this case, the other drain port must be plugged. The case of
the axial piston unit must be filled before fitting the piping and filling the
reservoir with hydraulic fluid. Because complete air bleeding and filling is not
possible in installation positions 6 and 8, the axial piston unit should be air bled
and filled in a horizontal position prior to installation.
