6.5.3 Demounting
Remove the axial securing device from the hollow shaft.
If frictional corrosion has occurred on the seating surfaces, rustreleasing agent may be used to
facilitate forcing off the gear unit. The rust releaser can be injected through the pressureoil connection
(see figure 25), using a pump.
When the rustreleasing agent has taken effect, pull the gear unit off using the device (see figures 27
and 28).
Removing the gear unit from the drivenmachine shaft can be done as follows:
preferably using a hydraulic lifting unit,
using forcingoff screws in an end plate (see figure 28), or
using a central threaded spindle.
Note
The end plate and/or the auxiliary plate for forcing off the gear unit are not included in the Siemens
delivery.
