Bosch Rexroth AG, A4VG Series35, RE92035-01-B/2019-11-25
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)
• Data sheet for 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 underground 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.
▶ No check valve is permitted in the drain line.
