Fig. 11-10: Assembling the rotor and spindle
The spindle usually slides into its end position (final stop on spindle)
without requiring additional force. If it does not slide into its end stop by
virtue of its own weight, the spindle can be forced into place in the rotor
with no more than 500 N (the force equal to the body weight of the
mechanic).
5. Let the rotor and spindle cool to room temperature.
6. Check whether the rotor has properly shrunk onto the spindle:
• Visually check whether the spindle is in its final position in the
rotor
• Check the concentricity of the spindle:
Check whether the concentricity of the spindle is still as high as it was
prior to shrink-fitting. If the concentricity has deteriorated, the spindle
is slightly deformed. This deformation is caused by stress which can
occur in the step interference fit during cooling.
Note: If the spindle is not in its final position and the necessary
concentricity can not be achieved, the measures described in
the “Measures to be Taken in the Case of Faulty Assembly”
section (below) must be taken.
7. Use the threaded pins to close the pressure oil connections in the
rotor. To do this: screw the threaded pins in all the way and secure
them against rotation with LOCITE 620 (for the gluing guidelines,
see section 11.3). The threaded pins must be glued into place in
such a way that they completely seal the connections against oil
pressure.
