♦ Push the device with the side (1) from the suction side through the impeller and center it in the bearing bushing.
♦ With the aid of a press, the bearing bush can now be removed (alternatively by axial striking with a rubber
hammer on the end face of the device).
Insert bearing bush:
♦ Place the bearing bush onto the rotor.
♦ Slide the device with the side (2) forward from the drive side through the impeller.
♦ By means of a press, the bearing bush can now be used (alternatively by axial striking with a rubber hammer on
the end face of the device).
