10.Increase the pressure to approx. 60 to 70 MPa (600 to 700 bar).
→ The unit floats.
The rotor is prevented from sliding off by the slotted nut and the spacing sleeve.
Note
A few oil drops can spurt out in the axial direction.
11.Reduce the oil pressure at the pump.
12.Check the radial runout at the reference mark. See the "Checking the radial runout"
figure.
13.If the required accuracy is not attained, repeat the pressure operation.
→ This rotates the rotor core and the shaft against one another.
14.Remove the extension pipe.
15.Place the "rotor - spindle shaft" system vertical.
→ Allow the oil to drip from the sleeve.
16.Store the unit for 24 hours.
→ Collect the escaping residual oil in the sump.
The "rotor - spindle shaft" system is fully loadable again after 24 hours.
17.Degrease the threaded holes and grub screws with e.g. Loctite 7061.
18.To secure the grub screw, apply Loctite 243 or similar to the threaded hole.
19.Screw the grub screws into the threaded hole.
20.Mark on the face the position of the rotor to the spindle.

Compensation for deformations caused by thermal joining
Thermal joining can cause deformation of the bearing seat. For this reason, we recommend
re-machining the bearing seat.
