6.5.2.1 Fitting with integrated DU bush
• Fit the gear unit by means of nut and threaded spindle. The counterforce is provided by the hollow shaft.
The hollow shaft must be exactly aligned with the machine shaft to avoid
canting. When fitting, ensure that the position of the teeth between the machine
shaft and hollow shaft is correct. The correct position can be determined by
turning the input shaft and/or by swivelling the gear unit lightly around the
hollow shaft.

6.5.2.2 Fitting with loose DU bush
The loose DU bush is pushed onto the machine shaft, fixed rigidly in position with a locating tie and then
pulled into the hollow shaft along with the machine shaft (see fig. 52).
The hollow shaft must be exactly aligned with the machine shaft to avoid
canting. When fitting, ensure that the position of the teeth between the machine
shaft and hollow shaft is correct. The correct position can be determined by
turning the input shaft and/or by swivelling the gear unit lightly around the
hollow shaft.
Instead of the nut and threaded spindle shown in the diagram, other types of equipment such as a hydraulic
lifting equipment (type Lucas) 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.
6.5.2.3 Axial fastening
Depending on type, secure the hollow shaft axially on the machine shaft (e.g. with locking ring, end plate,
set screw).
