7.5.3 Changing the radial ball bearings
When changing the radial ball bearings, you merely
need to remove the bearing pedestal from the plant.
For removal and dismantling of the bearing pedestal,
see Sections 7.6.1 and 7.6.2.
7.6 Dismantling
There are three possibilities for dismantling:
1. Dismantling the entire pump from the plant.
2. Dismantling the entire slide-in unit, i.e. the housing
remains in the plant.
3. Removing only the drive section, i.e. the pump
does not need to be drained (back-pull-out design).
See Section 5.8.
Dismantling of the entire pump is described.
¾
Secure pump on a workbench or worktop with the
suction nozzle facing downwards.
¾ Screw ring bolt M 8 into the drive shaft.
7.6.1 Removing bearing pedestal
Caution! Magnetic forces!
Risk of accident!
Axial forces are produced when the bearing pedestal
is pulled out of the lantern. These forces diminish
again abruptly after it has been removed.
The operating torque of the magnetic coupling in-
stalled is specified on the type plate.
¾
Undo bearing pedestal screwing 901/1, 554/4.
¾ Detach the bearing pedestal from the lantern cen-
tering, if necessary using 2 levers.
If required you have the possibility to use the two
threaded holes in the beating frame for jacking
screws.
