Fitting

The gear unit must not be cleaned in an explosive environment.
• 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 shaft­sealing 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.
Coat with a suitable lubricant to prevent frictional corrosion of the contact surfaces.
6.4.2.1 Fitting
• Fit the gear unit by means of a nut and a threaded spindle. The support is provided by the hollow shaft.
The hollow shaft must be exactly aligned with the machine shaft to avoid canting.

Instead of the nut and threaded spindle shown in the diagram, other types of equipment such as a hydraulic
lifting equipment (type "Lukas") may be used.
The hollow shaft may be tightened against a machine­shaft collar only if the gear­unit
configuration is one of the following:
­ Torque arm
­ Support with gear­unit swing base
With a different arrangement the bearings may be excessively stressed.

6.4.2.2 Axial fastening

Depending on type, secure the hollow shaft axially on the machine shaft (e.g. with locking ring, end plate,
set screw).
