Bosch Rexroth AG, A20V(L)O Series 1, RE 93100-01-B/2019-09-10
7 Installation
Prior to installation, the following documents should be to hand:
• Installation drawing for the axial piston unit (can be obtained from your contact
person at Bosch Rexroth)
• Hydraulic circuit diagram for the axial piston unit (in the installation drawing)
• Hydraulic circuit diagram for the machine/system (available from the machine/
system manufacturer upon request)
• Order confirmation (contains the order-related technical data for your
axial piston unit)
• of the axial piston unit (contains the permissible technical data)

7.1 Unpacking

The axial piston unit comes in a polyethylene material (PE) corrosion protection film.
CAUTION! Danger due to falling parts!
If the packaging is not opened correctly, parts may fall out and damage the parts
or even result in injury.
▶ Place the packaging on a level surface with sufficient load-bearing capacity.
▶ Only open the packaging from the top.
▶ Remove the packaging from the axial piston unit.
▶ Check the axial piston unit for transport damage and completeness; see chapter 4
"Scope of delivery" on page 19.
▶ Dispose of the packaging in accordance with the regulations in your country.

7.2 Installation conditions

The installation position and location of the axial piston unit essentially determine
how it is installed and commissioned (such as when filling and air bleeding
the axial piston unit).
▶ Fasten the axial piston unit so that the expected forces and torque can
be transferred without any danger. The machine/system manufacturer
is responsible for sizing the fasteners.
▶ Observe the permissible radial forces on the drive shaft when driving with radial
loading (belt drives). If necessary, store the belt pulley separately.
▶ Make sure the axial piston unit is always filled with hydraulic fluid during
commissioning and operation. Also do this also after relatively long standstill
periods, since the axial piston unit may drain out through the hydraulic lines.
▶ Direct the leakage in the housing area to the reservoir through the highest
drain port. Use a line size that matches the port.
▶ A check valve in the drain line is only permissible on a case-by-case
basis following consultation. Please consult your proper contact person
at Bosch Rexroth.
▶ To keep noise values low, use elastic elements to isolate all connecting lines from
all vibration-capable components (e.g. reservoir).
▶ Make sure the suction, drain, and return lines flow into the reservoir below
the minimum fluid level under all operating conditions. This will prevent air from
being drawn in and foam from forming.
