Tasks to be performed
Hydraulic Check hydraulic fluid level in the reservoir.
system
Check the operating temperature under comparable load
condition at the drain port and in the reservoir.
Perform hydraulic fluid analysis: Viscosity, aging and
contamination
Check filter.
The replacement interval may vary depending on the
cleanliness of the hydraulic fluid. We recommend using
a contamination indicator.
Axial piston Check axial piston unit for leakage.
unit Early detection of hydraulic fluid loss can help to find
faults on the machine/system and rectify them.
This is why Bosch Rexroth recommends always keeping
the axial piston unit and system clean.
Check axial piston unit for unusual noise development.
Check mounting elements for tight seating.
All fasteners have to be checked when the hydraulic
system is switched off, depressurized and cooled down.
10�3 Maintenance
The axial piston unit is low-maintenance when used as intended.
The service life of the axial piston unit is heavily dependent on the quality of the
hydraulic fluid. This is why we recommend changing the hydraulic fluid at least
once per year or every 2000 operating hours (whichever occurs first), or having
it analyzed by the hydraulic fluid manufacturer or a laboratory to determine its
suitability for further use.
The service life of the axial piston unit is limited to the service life of the bearings
used if the permissible operating parameters are observed. You can ask your local
contact person about service life based on load cycle. You can find their contact
information at https://addresses.boschrexroth.com
Based on these parameters, a maintenance interval should be determined by the
system manufacturer for the replacement of the bearings and included in the
maintenance schedule of the hydraulic system.
10�4 Repair
Bosch Rexroth offers a comprehensive range of services for the repair of Rexroth
axial piston units.
Repairs on the axial piston unit and its assembled parts should only be performed
by service centers certified by Bosch Rexroth.
▶ Only use original spare parts from Rexroth to repair the Rexroth
axial piston units, otherwise the functional reliability of the axial piston unit
cannot be guaranteed, and the warranty will be voided.
For questions regarding repairs, contact your proper Bosch Rexroth service partner
or the service department of the manufacturer's plant of the axial piston unit;
see chapter 10.5 "Spare parts" on page 49.
