Avoid canting when pulling the unit off.
The plate for forcing­out is not included in our delivery.
If the counterforce is provided not only by the hollow shaft, but also by the
housing, as shown in fig. 53, the forces used must not exceed the values given
in the following table 17.

If the above values are exceeded, the housing, the hollow­shaft bearings or
other gear components may be irreparably damaged. Before replacing the gear
unit on the machine shaft, always check the bearings for any signs of damage.
When using forcing 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.
6.6 Shaft­mounting gear unit with hollow shaft and shrink disk
The end of the driven machine shaft (material C60+N or higher strength) should have a centring means
to DIN 332 Form DS (with thread) in its end face (for connecting dimensions of the driven machine shaft,
see dimensioned drawing in the gear­unit documentation).
6.6.1 Fitting
• Remove the preservative agent from the hollow shaft and the machine shaft with a suitable cleaning
agent (such as benzine).
Do not allow the cleaning agent (e.g. benzine) to contact the shaft sealing rings.
Ensure adequate ventilation. Do not smoke!
Danger of explosion!
• Check the hollow and machine shafts to ensure that seats and edges are not damaged. If necessary,
rework the parts with a suitable tool and clean them again.
The bore of the hollow shaft and the machine shaft must be absolutely free of
grease in the area of the shrink disk seat.
This is essential for safe and reliable torque transmission.
Do not use contaminated solvents or dirty cloths for removing grease.
