10.2 Inspection

In order for the axial piston unit to be reliable and long-lasting, Bosch Rexroth
recommends inspecting the hydraulic system and axial piston unit on a regular basis,
and documenting and archiving the following operating conditions:
Table 12: Inspection schedule
Task 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.
Conduct hydraulic fluid analysis: Viscosity, aging and
contamination
Axial piston unit Check axial piston unit for leakage.
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 fastening 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. You can ask your local contact person about service life based on load cycle.

Based on these details, 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.
