Axial piston units

7 Installation
Prior to installation, the following documents should be to hand:
• Product-specific data sheet of the axial piston unit (contains the permissible
technical data, main dimensions and circuit diagrams of standard versions)
• Product-specific instruction manual (contains product-specific parameters)
• Installation drawing for the axial piston unit (can be obtained from your contact
person at Bosch Rexroth, if required)
• Hydraulic circuit diagram for the axial piston unit (in the product-specific
data sheet and on 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)
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 22.
▶ 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 transferring drives
or output drives with radial force 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.
▶ Depending on the specific product, a check valve in the drain line is only
permissible after consultation. Further information can be found in the
product-specific instruction manual or you can ask your responsible 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).
