With the universal tool supplied, carefully knock
the rotor and attached shaft out in the direction of
the coupling and then draw them out in the same
direction.
With this attachment you receive an
additional tool. Use one tool to hold the
shaft and the other to turn the rotor
anti-clockwise and withdraw it. You can
then withdraw the shaft from its tube.
The lower sleeve bearing is slit and can be
opened and pulled over the shaft. The upper
bearing can be pulled off in the direction of the
rotor.
Using the tool, the sleeve bearing can
be pushed out in the direction of the
coupling.
Replace defective parts. Bearings should only be
replaced in pairs.
Replace defective parts.
Reassemble in the reverse order. Use the shaft to press the sleeve
bearing into the stator tube from the
coupling side. Screw on the rotor and
tighten gently.
