Fault finding

5. FAULT FINDING

Hydraulic motor

Fault

Probable cause

Action

The motor does not run.

Mechanical stop in the drive.

The motor does not deliver 
enough torque because the pres-
sure difference across the motor 
is not great enough for the load.

Insufficient or no oil being sup-
plied to motor.

Check system pressure. If the 
pressure has risen to the relief 
valve setting, remove the load 
from the drive.

Investigate the pressure level in 
the system and correct the set-
ting of the pressure limiting valve 
if necessary.

Check the hydraulic system. 
Check the external leakage of 
the motor. (The D connection).

Motor rotates in wrong direction.

Oil supply connections to motor 
incorrectly connected.

Connect the oil supply correctly.

Motor runs jerkily.

Pressure or flow fluctuations in 
the hydraulic system.

Find the cause in the system or 
in the driven unit.

Noise in the motor.

The motor is being operated with 
the charge pressure too low.

Internal faults in the motor.

Adjust the charge pressure to the 
correct level. See .1  "Recom-
mended charge pressures".

Investigate the drain oil, if neces-
sary. Put a magnetic plug in the 
oil flow and check the material 
that sticks to the magnet. Steel 
particles indicate damage. Note 
that fine material from the cast-
ings may be desposited and 
does not mean internal damage 
in the motor.

External oil leakage on the mo-
tor.

The radial lip seal is worn.

Replace the radial lip seal.
