- Rest the rotor on one of its poles, then slide
it out. Use the tube as a lever arm to assist
dismantling.
- After extracting the rotor, be careful not to
damage the fan. If the fan is dismantled, it is
essential that it is replaced.
NOTE: If intervention is required on the
revolving
field
coil
(rewinding,
replacement of components), the rotor
assembly must be rebalanced.
4.6.7.2 - Reassembling the revolving
field coil
- Follow the dismantling procedure in
reverse order.
Take care not to knock the windings when
refitting the rotor in the stator.
- If the fan is being replaced, assemble the
parts as shown in the following diagram. Fit
a tube and a threaded screw.
Follow the procedure for reassembling the
bearings (see section 4.6.6).
4.6.8 - Accessing, checking and
replacing the nanophase rectifier
4.6.8.1 - Dismantling
- Remove the inspection and access doors
[59] and [42].
- Remove the cover [144].
- Remove the cover supports [146] and
[147].
- Cut the fixing clamps on the cables and
bundles.
- Disconnect the R220 AVR and the CCM
module.
- Remove the 8 screws from the supports
[141] and [142].
- Remove the nanophase rectifier [140] and
disconnect the power cables.
4.6.8.2 - Reassembly
- Reconnect the power cables to the rectifier
making sure they are in the correct position
(T1 to T9).
- Fix the rectifier on the supports [141] and
[142] using the 8 screws.
- Reconnect the R 220 VS AVR and the CCM
module.
- Place the fixing clamps on the cable
bundle.
- Replace the cover supports [146] and
[147].
- Replace the cover [144].
