8.3.8 Rotor replacement<br />
Danger!<br />
The brake must be free of residual torque.<br />
1. Loosen the connecting cable.<br />
2. Evenly release the screws and remove them completely.<br />
3. Completely remove the stator from the end shield. Observe the connecting cables.<br />
4. Completely remove the rotor from the hub.<br />
5. Check the toothed part of the hub.<br />
6. In case of wear, replace the hub, too.<br />
7. Check the friction surface of the end shield. If the flange / friction plate is severely<br />
gouged, it must be replaced. If the end shield is severely gouged, the friction surface<br />
must be reprocessed.<br />
8. Measure the rotor thickness (new rotor) and the height of head of the sleeve bolts<br />
using a caliper gauge.<br />
9. The distance between the stator and the armature plate is calculated as follows:<br />
Distance = rotor thickness + s Lürated − height of head<br />
"s Lürated ", ( 51)<br />
10. Evenly remove the sleeve bolts until the calculated distance is reached between the<br />
stator and the armature plate.<br />
11. Completely mount the new rotor and set the stator, ( 51).<br />
12. Connect the connecting cable again.<br />
