6.6.1.2 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. 55).
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 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.
6.6.1.3 Axial fastening
If the shrink disk is fitted according to instructions (see item 6.6), the gear unit is fixed securely in the axial
direction. Additional fastening is not required.
