10.3 Maintenance
The axial piston unit is low maintenance when used properly.
The service life of the axial piston unit is heavily dependent on the quality of the
hydraulic fluid. For this reason, we recommend changing the hydraulic fluid at least
once per year or every 2000 operating hours (which ever 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 by the service life of the bearings
fitted. The service life on the basis of the load cycle can be requested from the
responsible Bosch Rexroth Service partner, see chapter 10.5 “Spare parts” on
page49 for address. Based on these details, a maintenance period is to 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

axial piston units.
Repairs on the axial piston unit and its fittings may only be performed by service
