Tabelle 31: Axial piston unit malfunction table

Malfunction

Possible cause

Remedy

Unusual noises

Insufficient air bleeding of the hydraulic 
system

Fill the axial piston unit, suction line for the 
hydraulic pump and the reservoir
Completely air bleed the axial piston unit and 
hydraulic system
Check correct installation position

Insufficient suction conditions, 
e.g., insufficient dimensioning of the suction 
line, viscosity of the hydraulic fluid too high, 
suction height too high, suction pressure 
too low, foreign particles in the suction line, 
impermissible filter in the suction line

Machine/system manufacturer: Check the 
system, e.g. optimize inlet conditions, 
use suitable hydraulic fluid
Fill the suction line with hydraulic fluid

Remove foreign particles from the suction line

Drive speed too high

Machine/system manufacturer: 
Reduce drive speed

Wrong direction of rotation

Machine/system manufacturer: Check correct 
direction of rotation, see chapter 7.5.1 
"Preparation" on page 41

Improper mounting of the axial piston unit

Check the mounting of the axial piston 
unit according to the specifications of the 
machine/system manufacturer – observe 
tightening torques

Improper mounting of assembled parts, 
hydraulic lines or improper installation of the 
coupling

Fasten assembled parts according to the 
parameters provided by the coupling fitting 
manufacturer

Resonances due to a defective or unsuitable 
elastic coupling

Check the specification of the elastic coupling 
and/or replace defective or worn coupling

Valve and controller vibrate

Optimize the adjustment of the controller of 
the axial piston unit and the pressure limitation 
in the hydraulic system

Mechanical damage to the axial piston unit 
(e.g. bearing damage)

Replace axial piston unit

Contact Bosch Rexroth Service

Increased, unusual vibration

Bearings worn
