Fig. 11-7: 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 parts 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.
