a)
Loosen the fasteners (if applicable) holding the
motor to the baseplate.
b) To remove the motor from the wet end, on Group
A and 1 pumps remove the four (4) motor
flange/lantern fasteners [6570.6]. On Group B
and 2 pumps remove the six (6) lantern/bearing
holder fasteners [6570.8].
c) Screw the two (2) square head jackbolts [6575]
in the lantern through the threaded holes until
each comes into contact with its mating part.
(Figure 6-15 and 6-16) Continue to screw both
jackbolts evenly to disengage the motor from the
wet end of the pump. (Figure 6-17 and 6-18)
d) The drive end can now be moved to the repair
shop.

6.7.4
Removal of drive end from the wet end
The magnetic coupling will remain engaged
even after the fasteners that attach the drive end to
the wet end have been removed. This is due to the
strong radial and axial forces associated with the
magnetic coupling.
Do not attempt to remove the drive end
from the wet end without using the jackbolts. The
magnetic force can cause severe personal injury.
Be sure to separate the inner and
outer magnet assemblies evenly. Cocking of the two
can result in serious damage to the magnets and/or
containment shell. It is best to alternatively give each
bolt a turn to ensure proper and even separation.
