14.2 Malfunction table
Table 15: 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7.4.1"Preparation" onpage31
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
Mount assembled parts according tothe
information provided bythecoupling fitting
manufacturer
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
