42/52 Maintenance and repair
Bosch Rexroth AG, A2FM/A2FE Series 70, RE 91071-01-B/03.2015
Task to be performed
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 to rectify them. For this
reason, Bosch Rexroth recommends that the axial piston
unit and system are always kept in a clean condition.
Check axial piston unit for unusual noise development.
Check fixing 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 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 (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 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
page 43 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

Bosch Rexroth offers a comprehensive range of services for the repair of Rexroth
axial piston units.
Repairs on the axial piston unit and its fittings may only be performed by service
centers certified by Bosch Rexroth.
▶ Use exclusively original spare parts from Rexroth to repair the Rexroth axial
piston units, otherwise the functional reliability of the axial piston unit cannot be
assured and the warranty is void.
In the event of questions regarding repairs, contact your responsible Bosch Rexroth
service partner or the service department of the manufacturer's plant for the axial
piston unit, see Chapter 10.5 "Spare parts" on page 43.
