Installation and maintenance manual , Hägglunds CB, RE 15302-WA/05.2019

Fault

Probable cause

Action

The motor does not run.

Mechanical stop in the drive.

Check system pressure. If the pressure has

risen to the relief valve setting, remove the load
from the drive.

The motor does not deliver enough torque

because the pressure difference across the

motor is not enough for the load.

Investigate the pressure level in the system and

correct the setting of the pressure limiting valve

if necessary.

Insufficient or no oil being supplied to motor.

Check the hydraulic system. Check the external

leakage of the motor (D connection).

Motor rotates in wrong direction.

Oil supply connections to motor incorrectly

connected.

Connect the oil supply correctly.

Motor runs rough.

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 too low
charge pressure.

Adjust the charge pressure to the correct level.
See chapter Recommended charge pressure in
data sheet

RE 15302.

Internal faults in the motor.

Investigate the drain oil, if necessary. 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 castings may be deposited

and does not mean internal damage in the
motor.

External oil leakage on the motor.

The radial lip seals or other seals is worn or
damaged.

Replace the damaged seals.
