Demounting

• Depending on the facilities available on site, the gear unit may be forced off the shaft using forcing­off
bolts in an end plate (see figure 17), a central threaded spindle or preferably a hydraulic lifting unit.

Avoid canting when pulling the unit off.
When using forcing­off screws or threaded spindles, the head of the thread pressing against
the driven machine should be rounded and well greased to reduce the risk of seizing at this
point.

Support bracket

Fig. 18: Support bracket
For the position of the torque arm refer to the dimensioned drawing in the gear­unit documentation.
The support bracket must be vertical and level in the area of the torque­reaction arm.
It must be designed in such a way that no resonance vibrations are set up and that no vibrations can be
transmitted from adjacent foundations. Steel structures on which the unit is to be fitted must be rigid. They
must be designed according to the weight and torque, taking into account the forces acting on the gear unit.
