6.5.3 Demounting
• Remove the axial securing device from the hollow shaft.
• If frictional corrosion has occurred on the seating surfaces, rust­releasing agent may be used in order
to facilitate forcing off the gear unit. The rust releaser can be injected through the pressure­oil connection
(see Fig. 53), e.g. using a pump.
• The end plate and the locking ring must first be removed.
• When the rust­releasing agent has taken effect, pull the gear unit off with the device (see figs. 53
and/or 54).
• Removing the gear unit from the driven­machine shaft can be done locally as follows:
─ using forcing screws in an end plate (see Fig. 54) or
─ using a central threaded spindle or
─ preferably using a hydraulic lifting unit ("Lucas").
