Dismantling
Follow the procedure for dismantling the
bearings.
- Remove the coupling dise (single bearing
alternator) and insert a tube of the
corresponding diameter on the shaft end.
- Rest the rotor on one of its pales, then si ide
it out. Use the tube as a lever arm to assist
dismantling.
-After extraction of the rotor, be careful not
to damage the fan or dismantle it.
- Remove the revolving field coil (rotor) and
place on special V-shaped supports.
NOTE: If intervention is required on the
revolving
field
coil
(rewinding,
replacement of components), the rotor
assembly must be rebalanced.
Reassembling the revolving field coil
- Followthe dismantling procedure in reverse
order.
Take care not to knock the windings when
refitting the rotor in the stator.
- Refit the fan with its fixing bolts on the hub.
Follow the procedure for refitting the
