Proceed as follows:
1. Let the rotor and spindle cool.
2. Seal one of the two oil connections on the rotor with a threaded pin.
This means screwing the threaded pin in all the way and securing it
against turning with LOCITE 620 (for gluing guidelines, see section
11.3). The threaded pin must be glued into place in such a way that
it completely seals the connection against oil pressure.
3. Using appropriate assembly tools, clamp the rotor and spindle to
each other in such a way that the rotor is firmly held in position on
the spindle.
Note: The rotor must not be permitted to shift axially on the spindle
while the oil is being injected.
4. Connect the oil pump.
Use oil with a viscosity of 300 mm
2
/s at +20°C! This ensures that the
oil will quickly and completely flow out after "floating".

5. Pump oil into the step interference fit.
Note: Oil is exuded!
Have a collecting pan ready.
Slowly increase the oil pressure until oil begins to leak out of the coil end
of the interference interface.
A separating oil film forms between the rotor and spindle. Due to this
floating of the rotor on the spindle, the tension that resulted from
shrink-fitting is released.
6. Eliminate all pressure from the oil pump, supply lines and press
group.
7. Open both oil connections.
8. Bring the spindle with the clamping device into a vertical position
and, using compressed air, force the oil out of the step interference
fit (see Fig.11-14).
9. Let oil completely run out of the step interference fit.
