9.0 REPLACING PARTS
• Immediately replace parts and components if they are not able to guarantee safe and reliable
operation.
• Never improvise repairs.
• The use of non-original spare parts not only renders the warranty null and void but can jeopard-
ise the gear unit’s operation.
9.1 REMOVING THE MOTOR
If during operation the mobile coupling between the motor and gear unit has not rusted signicant-
ly, it should be possible to remove the motor without applying excessive force.
If instead, it proves difcult to remove the motor, do not use screwdrivers or levers to apply force
as this may damage the anges and mating surfaces, but proceed as illustrated below.
1. Drill and thread the motor shaft (fan side).
2. Screw an impact extractor tool into the bore.
3. Undo the bolts xing the motor to the gear unit.
4. Detach the motor by means of the inertial force of the extractor.
