11.2.1 - 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 supported on the flange (6);
- remove the key (21) and withdraw the seals (39 and 54) for
motors with feet, (39) for flanged motors);
- unscrew the assembly rods (14) then withdraw them;
- unscrew the fixing screws (40) of the inner cover (33);
- using a bronze drift, extract the flanges (5 et 6) by gently
tapping on the flange pad; recover the pre-load washer (59);
- withdraw the circlips (38) if necessary (flange motor);
- remove the rotor (3) from the stator (1) taking care not to touch
the winding;
- extract the bearings (30) and (50) with a bearing puller whilst
protecting the shaft end with a washer; avoid making contact
with the shaft support surface.
11.2.2 - Re-fitting
- See § 10.2.4 before refitting;
- introduce the rotor front side inner cap (33) then refit the new
bearings onto the shaft.
- fit the circlips (38) for flanged motors;
- introduce the rotor (3) into the stator (1) taking all precautions
not to make contact with the winding;
- fit the pre-load washer (59) with a little grease in the bottom of
the rear flange bearing cage (6), then refit the rear flange (6),
positioning it on the stator;
- for fitting the cap (33), screw a threaded rod of the same
diameter as the screws (40) into one of the threaded holes of
the cap to ensure the correct angular positioning during refitting
of the front flange (5); for a flange, fit a new seal (39) spring
towards the exterior;
- refit the flange (5) taking care with the positioning of any cap;
- place the assembly rods in position (14) and tighten the nuts
diagonally to the recommended torque (see § 10.2.4);
- fix the cap with its screws (33);
- fit the new flange seals with grease (54) to the rear, (39) to the
front for motors with feet;
- fit the fan (7) wedging it in place with a drift;
- check that the rotor turns freely by hand (and that there is no
axial play if there is an immobilised bearing housing);
- refit the cover (13) and fix it in place with the screws (27);
- refit the key (21).
Bearing housings must be fitted with a front interior cap.
