12.1.1 - Removal
- Remove the cover (13) once the screws (27) are removed;
- extract the fan (7) using a hub puller or failing this two
diametrically opposite levers (e.g. screwdrivers) supported on
the flange (6);
- withdraw the assembly rods (14);
- withdraw the key (21);
- using a wooden mallet, tap the fan side of the shaft to release
the shaft extension side flange (5);
- remove the rotor shaft (3) and front flange (5) avoiding making
contact with the winding;
- withdraw the fan side flange (6);
- recover the preload washer (59);
- withdraw the circlips (60) on flanged motors using an elbowed
circlips pliers;
- separate the front flange from the rotor shaft;
- the shaft is then seen with its 2 bearings and where relevant
the circlips.
To remove the bearings use a bearing puller and avoid making
contact with the shaft support surfaces.
- For each flange remove all traces of sealant located on the
housing on the frame.
12.1.2 - Refitting motor without circlips
- Each flange must be fitted with a continuous bead silicone or
polyurethane sealant at the housing on the frame;
- fit the bearings on the rotor shaft;
- introduce the rotor into the stator taking all precautions not to
make contact with the winding;
- fit the front flange (5);
- fit the rear flange (6) after placing the pre-load washer (59) in
the bearing housing;
- place the assembly rods in position (14) and tighten the nuts
diagonally to the recommended torque (see § 10.2.4);
- fit new flange seals (39, 54) using grease;
- fit the fan (7) wedging it in place with a drift;
- check that the motor turns freely by hand and that there is no
radial play;
- refit the cover (13) and fix it in place with the screws (27);
- refit the key (21).
12.1.3 - Refitting motor with flange and circlips
- Each flange must be fitted with a continuous bead silicone or
polyurethane sealant at the housing on the frame.
- Fit the front bearing (30) in the flange (5) resting supported on
the outer ring;
- fit the circlips (60);
- fit this assembly on the rotor (3) resting on the interior bearing
ring;
- fit the rear bearing on the rotor;
- introduce the rotor (3) and flange (5) assembly into the stator
taking all precautions not to make contact with the winding;
- fit the rear flange (6) after placing the pre-load washer (59) in
the bearing housing;
- place the assembly rods in position (14) and tighten the nuts
diagonally to the recommended torque (see § 10.2.4);
- fit new flange seals (39, 54) using grease;
- fit the fan (7) wedging it in place with a drift;
- check that the motor turns freely by hand and that there is no
axial play;
- refit the cover (13) and fix it in place with the screws (27);
- refit the key (21).
