16. Clean the bearing journal with a clean cloth.
17. Heat the new bearing (pos. 153) to maximum 110 °C.
18. Fit the heated bearing (pos. 153) on the shaft (pos. 172).
19. MGE 90: Fit locking ring (pos. 188) on the shaft.
20. Place the flange in the vice and clean the bearing seat with a
clean cloth.
21. Clean the bearing and fit the rotor in the flange.
22. MGE 90: Fit locking ring (pos. 187) so that the bearing is held
by the flange.
23. Clean the bearing journal in the non-drive end with a clean
cloth.
24. Heat bearing (pos. 154) to maximum 110 °C.
25. Fit the heated bearing (pos. 154) on the shaft (pos. 172).
26. Remove the cardboard from the rotor when the bearings have
cooled down.
27. Fit the gasket (pos. 156d) on the flange.
28. Check that the corrugated spring water (pos. 158) is correctly
fitted in the stator housing.
29. Gently insert the rotor into the stator.
30. Unscrew the puller to slowly insert the rotor into the stator.
Press flange and stator together when the bearing (pos. 154)
has engaged with the stator housing. Check that the drain
hole of the flange faces downwards.
31. Remove the puller and cross-tighten screws (pos. 185).
32. Lubricate shafts ends and fit seal rings.
33. Check that the shaft can rotate freely.
34. Fit fan and cover.
See section 7.11 Replacing the fan.
35. Fit the terminal box.
See section 7.10 Replacing the stator housing.
7.13 Replacing IP55 seal rings with IP66 rings
1. Disconnect the power supply.
2. Remove the stator housing from the terminal box.
See section 7.10 Replacing the stator housing.
3. Remove the fan. See section 7.11 Replacing the fan.
4. Remove seal rings (pos. 156c) from shaft (pos. 172).
5. Lubricate gamma ring (pos. 159d) and fit it on the drive end of
the shaft.
6. Lift the motor so that the non-drive end of the shaft rests on a
solid, vibration-free surface.
7. Gently knock the ring home with the relevant punch.
The distance between flange (pos. 156b) and ring must be 0.8
to 1.3 mm.
8. Support the motor so that it rests on the drive end of the shaft.
9. Lubricate gamma ring (pos. 159e) and fit it on the non-drive
end of the shaft.
10. Gently knock the ring home with the relevant punch.
The distance between stator housing (pos. 150) and ring must
be 0.8 to 1.3 mm.
11. Fit fan and cover.
See section 7.11 Replacing the fan.
12. Fit the terminal box.
See section 7.10 Replacing the stator housing.
Follow the instructions of bearing and bearing
heater.
Warning
Use heat-resistant gloves.
Follow the instructions of bearing and bearing
heater.
Warning
Use heat-resistant gloves.
Warning
Watch your fingers when you insert the rotor, as
the magnet will pull rotor and stator together with
big force.
The design of the punch ensures correct
tolerances.
