1. Unscrew both grub screws from the rotor core sleeve.
2. Wrap the threaded shoulder on the extension tube and the second grub screw with Teflon
sealing tape.
3. Screw the extension tube firmly into the sleeve of the rotor core.
4. Place the rotor core with spindle shaft, slotted nut and the spacing sleeve on the prism.
5. Attach the oil hand pump.
6. Vent the hydraulic system.
7. Screw the second grub screw with Teflon sealing tape tightly into the sleeve thread.
8. Force the oil with the hand pump slowly until the pressure of approx. 50 MPa (500 bar) is
reached.
9. Allow the oil to act for approximately 15 minutes.
→ The oil penetrates the fitting gaps and distributes itself.
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.
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.
→ The rotor core and the shaft are rotated against each other.
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.
You have removed tensions in the rotor.
