• Fork wrench DIN 894 or DIN 895
• Hexagon socket wrench DIN 911
• Hook wrench
• Fork wrench
11.2 Disassembling
Proceed as follows when disassembling an
servomotor:
1. Loosen the connecting cable tightening
spindle from the interface at the motor.
When doing so, proceed according to
the disassembly instructions for the
connecting cable tightening spindle.
2. Loosen the union nut of the angle plug
of the measurement transducer cable at
the interface at the servomotor and pull
the plug.
3. Clamp the motor with the installed gear-
box carefully into a bench vise.
CAUTION
Hot surfaces possible, particularly
on motor housings and gearboxes!
Risk of injury! Risk of burns!
Do not touch device housing surfa-
ces at heat sources! Risk of burns!
Do not touch housing surfaces of
motors and gearboxes! Risk of burns!
Depending on the operating condi-
tions, temperatures during or after
operation may exceed 60 °C
(140 °F).
After switching off the motors, allow
them to cool down sufficiently before
accessing them.
Wear protective gloves or do not
work near hot surfaces.
NOTE
Incorrect motor assembly/disas-
sembly possible!
Material damage to the motor due to in-
correct clamping into a bench vise.
Clamp the motor only slightly and
use extensive braces.
NOTE
Incorrect assembly/disassembly of
planetary gearbox possible!
Material damage and malfunction of the
planetary gearbox in later operation.
During assembly/disassembly, it is
imperative that you hold the planetary
gearbox horizontally. Otherwise,
there is the risk of the gears and
needle bearings loosening from the
gearbox.
