11. Repair
Procedure 1. Clean the toothing of the motor and the gear unit before installation and
apply a thin but continuous coat of Microlube GL 261 grease. See safety
data sheet in Section (>>> 15.1 "Safety data sheets" page 123).
2. Clean the mounting surface for the servomotor on the gear unit.
3. Attach lifting tackle to servomotor.
4. Insert the servomotor.
The motor shaft must not be subjected to any axial loads during installa-
tion.
When inserting the servomotor, it must be ensured that the spline shaft
connection of the servomotor and gear unit meshes properly. This can be
facilitated by gently turning the servomotor during insertion.
5. Fasten the servomotor with four M12x30-8.8 Allen screws (>>> Fig. 11-4)
(3) and lock washers.
6. Tighten the four M12x30-8.8 Allen screws (3) with a torque of M
A
= 78 Nm.
7. Remove the lifting tackle.
8. Install the drive assembly as described in Section (>>> 11.1.2 "Installing
the drive assembly" page 74).
Caution!
When installing the motor, it must be ensured that the toothing of the motor
and gear unit are not damaged.
Warning!
The servomotor weighs approx. 30 kg. When removing or installing the ser-
vomotor, care must be taken to avoid injury by crushing. Protective gloves
must be worn.
Caution!
The servomotor must not be tilted. The orientation of the servomotor is iden-
tified from the position of the sockets. When the motor unit is installed, these
sockets must be positioned in the same way as before removal.
