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.
See fig. 9.

Adjusting of shaft height
24. When the shaft has been adjusted to the correct height,
tighten the lock screw with the specified torque, using the
torque screwdriver. See section
25. Turn the stator housing to horisontal position.
26. Fit the end cover, pos. 13, and fasten it with the four 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 into the motor until it has been almost 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.
10.

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 the 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. Firstyou
cross-tighten with half a torque and then with a full torque.
Note:
Fit the last screw at the cable plug with the motor cable.
41. Insert the motor cable, pos. 220, into the cable plug.
Note:
For proper sealing, Grundfos always recommends that
you use a new motor cable
42. Tighten the motor cable with the screws, pos. 220a, and the
last screw, pos. 50, for the shaft seal housing.
43. Tighten the screws for the motor cable with the specified
torque. See section
3. Tightening torques and lubricants
.
44. Cross-tighten the screws in the shaft seal housing with the
specified torque. See section
.
45. 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.
