9.
If necessary, use two suitable attachment points to secure the motor with the lifting gear so that the motor shaft is
pointing down vertically.
10. Turn the motor in an axial position to the gear unit so that the nameplates are on the same side, if possible, and can
also be read after installation in the machine.
11. If the motor shaft has a keyway, position the motor shaft so that the keyway faces the slot of the clamping hub (10).
12. An elastic bellow coupling is installed in the MF/MFL motor adapter that can assume a slightly tilted position, as long
as the clamping hub is not connected with the motor shaft. Correct any existing tilt of the clamping hub before
inserting the motor shaft.
13. Carefully place the motor on the motor adapter (4) and make sure that the motor shaft is inserted (7) in the clamping
hub (15) so that it is centered and not at an angle.
14. If the motor shaft cannot be inserted into the clamping hub, do not use force and instead turn the locking screw (11)
counterclockwise one quarter rotation with the hexagon insert (3) (in this process, the clamping hub widens because
the cross pin (12) locks against the cylinder head of the locking screw). The size of the hexagon insert can be found on
the adhesive label (14) as well as in the following tables.
15. If necessary, repeat the previous step.
16. The contact surfaces of the motor flange and motor adapter flange must fit together without a gap. If this is not the
case, do not use force and instead check the dimensions of the motor.
17. Mount the motor on the motor adapter with screws (9). Tighten the screws evenly, with increasing torque and
alternating diagonally. The tightening torque can be found in the chapter
18. Insert the torque wrench (2) in the hexagon insert (3) and tighten the locking screw (11). The corresponding tightening
torque can be found in the following table and on the adhesive label on the motor adapter.
19. If the motor flange does not fully cover the bores or openings of the motor adapter, seal off the openings with a
suitable sealant. This maintains the protection class of the gear unit so that dust and water cannot get into the interior
of the motor adapter.
20. Plug the access hole with the threaded sealing plug (13) by screwing it in until it is flush with the surface of the motor
adapter.
