17. Fit the compensation disc (pos. 1038) into the N-end of the
motor housing.
18. Insert the rotor into the motor housing. Connect the wires of the
water-in-oil sensor (pos. 1049) before the rotor is fully inserted.
Note Align the motor flange with the water-in-oil sensor
pointing downwards/away from the terminal box.
19. Fit the screws (pos. 1021) and tighten them a little by hand.
20. Place the motor in horizontal position.
21. Fit the cable flange (pos. 1002) and the O-ring (pos. 1007) on
the cable (pos. 1001).
22. Lubricate the O-ring with soapy water or cream and fit it into the
cable flange.
23. Fit the cable guide (pos. 1003), the large cable seal (pos. 1004),
the thrust washer (pos. 1005) and the small cable seal (pos.
1006) on the cable (pos. 1001).
24. Lubricate the complete seal unit with soapy water or cream and
insert it into the terminal box.
25. Lubricate the threads of the screws (pos. 1008) with Loctite 243.
26. Fit the screws into the cable flange and tighten them. See
section Torques and lubricants.
27. Fit the cable relief (pos. 1009) on the cable.
Note Make sure that you have enough cable in the terminal
box before tightening the cable relief.
28. Fit the screw (pos. 1028) and the lock washer (pos. 1029).
29. Connect the wires according to the notes you made during
dismantling. Secure connections with terminal tubes and shrink-
on sleeves.
30. Remove the screw (pos. 1041) and the washer (pos. 1040) from
the motor housing.
31. Wrap PFTE tape around the plug (pos. 1052).
32. Fit the plug into the motor housing and tighten it. See section
Torques and lubricants.
33. Lubricate the screw (pos. 1041) with Loctite 511 and fit the
washer (pos. 1040) on the screw.
34. Fit the screw into the motor housing (pos. 1017) and tighten it.
See section Torques and lubricants.
