1. Remove the coupling guards (681) and the coupling shells (862).
2. Remove the seal protection bracket (89-11.03) and its mounting material. For pumps with a taper piece
(722), with motor of 5.5 kW or higher, the two bolts (914.02 or 901.02) have to be placed back to connect
the taper piece to the motor stool. Thoroughly clean the motor stool (341), the shaft (210), the coupling
shells (862) and the motor shaft.
3. Loosely fasten the coupling shells (862) with the coupling pin (560) on the shaft (210). Use the hexagon
socket head cap screw (914.01) and the nut (920.01) for this. When the pump is equipped with a steel
coupling, never use the same coupling twice but order a new one.
4. Place the motor on the motor stool (341).
5. Pump with cartridge seal:
• Loosen the three cartridge grub screws (904) one turn.
• Push the hydraulic pump assembly in the lowest position.
• Tighten the three cartridge grub screws (904) rmly to the shaft.
6. Tighten the lower bolts of the coupling shells (862) in such a way that the coupling slightly clamps around
the motor shaft.
7. For pump series VMS: use a su󰀩cient tyre iron to lift the coupling (and hydraulic assembly) 1.5 mm
higher then the lowest position. For easy and accurate adjustment of the coupling contact your supplier for
the appropriate toolkit for hydraulics adjustment.
