Dismounting
Stop!
¯ Before dismantling the machine shaft, mount an adequately
dimensioned load handling device at the gearbox.
¯ Ensure pretensioning of the drive mechanism, preventing the gearbox
from falling into the drive mechanism when it is loosened from the
plug−in shaft.
¯ When removing the hollow shaft via the housing, impermissibly great
forces may be generated.
¯ Tensioning of the hollow shaft causes a bearing failure and damage of
the gearbox housing.
1. Undo axial gearbox locking in the hollow shaft.
2. Remove/extract the gearbox from the motor shaft using an appropriate auxiliary
tool (LEERER MERKER).
