When disassembling the gear unit from the machine shaft, canting must be avoided. Note The auxiliary washer for forcing out is not part of the delivery from Siemens. NOTICE Property damage Damage to the gear unit housing or other gear unit components.If the support is provided not only by the hollow shaft when fitting the gear unit, but also by the housing,as shown in figure 2, the forces used must not exceed the values given in the following table 8. Prior to refitting the gear unit onto the machine shaft, the hollow shaft bearings must be checked for damage.

For the connection dimensions of the machine shaft, see dimensioned drawing in the gear unit documentation. 6.7.1 Preparatory work For simpler disassembly (also see item 6.7. we recommend connecting the shaft end of the machine to pressure oil supply, which terminates in the recess of the hollow shaft (see figure . This connection may also be used for supplying rust releasing agent. Fig. 2: Hollow shaft and shrink disk, prep
