23. To adjust the shaft height, attend to the ND-end of the motor.
Slacken the lock screw, pos. 45a, in the shaft height adjusting
unit, pos. 45, and adjust the height by turning the screw, pos,.
45b, by using the shaft height adjustment spanner, pos. U.

Adjusting of shaft height
24. When the shaft has been adjusted to the correct height,
tighten the lock screw with the specified torque using a torque
screwdriver. See section
3. Tightening torques and lubricants
.
25. Turn the stator housing to horizontal position.
26. Fit the end cover, pos. 13, and fasten it with the four belonging
screws, pos. 46.
Note:
Nyltites must be renewed on all screws
27. Cross-tighten the screws with the specified torque. See
section
3. Tightening torques and lubricants
.
28. Turn the stator housing to vertical position, with the D-end
facing upwards.
29. Fill motor liquid (SML-3) into the stator housing until it has
been filled.
30. Move the shaft up and down and rotate the shaft to let air
escape.
31. Refill the stator housing with motor liquid
32. Carefully insert the radial bearing, pos. 5, into the stator
housing.
Note:
It is important that you position the radial bearing so it is
not resting on the taps on the upthrust ring, when you mount
the shaft seal housing. In such case the upthrust ring will be
forced down.
Check that the radial bearing is positioned correctly by turning
it with a screwdriver. If the radial bearing is resting on the taps
of the upthrust ring, it will drop down when you turn it. See. fig.
18.

Positioning of radial bearing
33. Slide the washer, pos. 28, down on the shaft, so its positioned
in the recess of the radial bearing.
34. Lubricate the rotating part of the shaft sealing, pos. 34, and
the shaft with motor liquid.
35. Fit the rotating part of the shaft seal onto the shaft, and press
it down using a punch, pos. V.
36. Lubricate the recess inside the shaft seal housing, pos 32.
37. Press the stationary part of the shaft seal into the recess of
the shaft seal housing, using a punch, pos. V.
Note:
On MS6000R,you must press a lip seal, pos. 32a, into
the shaft seal, before you insert the stationary part of the shaft
seal.
38. Fit the shaft seal housing with an O-ring, pos. 24, and
lubricate it.
39. Fit the shaft seal housing, pos. 32, into the top of the motor
and press it down into place by using the punch for shaft seal,
pos.
V.
40. Fit the four screws, pos. 50, into the shaft seal housing and
cross-tighten the shaft seal housing in two steps. First you
cross-tighten with half a torque and then with a full torque.
See section
3. Tightening torques and lubricants
.
41. Mount the flange extension, pos.25a, onto the motor head.
42. Fasten the flange extension with the four screws, pos. 22,
including the washers, pos. 21.
43. Cross-tighten the screws using a torque wrench combined
with the machined Torx 50 head driver, pos. M, or ring
spanner, pos. N. See section
.
44. Insert the motor cable, pos. 220, into the cable plug.
Note:
For proper sealing, Grundfos always recommends that
you use a new motor cable.
45. Tighten the motor cable with the screws, pos. 220a, using a
torque screwdriver. See section
.
46. Mount the screw, pos. 25b, that secures the earth plate of the
cable plug to the flange extension.
47. Tighten this screw with the specified torque. See section
3. Tightening torques and lubricants
48. Fit the sand fighter, pos. 27, on the shaft and push it down to
the shaft seal housing, pos. 32.
Make sure that the steel ring inside the sand fighter is facing
the shaft seal housing.
