6.7 Shaft­mounted gear unit with hollow shaft and shrink disk
The end of the driven­machine shaft (material C60+N or higher strength) should have a centring means

Preparatory work

To facilitate demounting (see item 6.7.4), we recommend providing a connection for pressure oil on the
end of the driven­machine shaft end, which is drilled through to the hollow­shaft recess (see figure 33).
This connection may also be used for supplying rust­releasing agent.
