c)
Rotate the bearing holder [3830] so that holes 
are 
located at the 3, 6, 9, and 12 o’clock
positions with the flat being forced to be at the 12 
o’clock position, which is in line with the lifting 
lug. 
d)
See section 6.6 for impeller assembly.
e)
Install the casing [1100] onto the lantern/bearing 
holder with studs and nuts [6572 and 6580]. 
 
6.9.3.2 
Group B and 2
a)
Install gasket [4610.1] into groove on bearing 
holder [3830] 
b)
To continue the assembly process the bearing 
holder should be support horizontally. A tapped 
hole is located at the 12 o’clock position on the 
holder [3830] so that an eyebolt can be engaged. 
An appropriate lifting device should be attached 
to the eyebolt, placing it in light tension to 
support the wet end. See Figure 6-45.

c)
Install the inner magnet/shaft assembly through 
the bushing [3300] that is located in the bearing 
holder [3830]. 
d)
Place the containment shell [3500] over the inner 
magnet followed by retaining ring [2530]. 
The retainer ring [2530] is
manufactured from carbon steel and may attach to 
the containment shell [3500] upon installation due to 
the presence of magnets in the inner magnet 
assembly. 
 
e) 
Install and tighten the twelve (12) retainer 
ring/containment shell cap screws [6570.7]. 
f)
See section 6.6 for impeller assembly.
g)
Install the casing [1100] onto the bearing holder 
with studs and nuts [6572 and 6580]. 
 
6.9.4 
Mounting the wet end to the power end
Do not attempt to assemble the drive
end to the wet end without using the jackbolts. The 
magnetic force can cause severe personal injury. 
 
Be sure to engage 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. 
 
Thread the entire length of the square head
jackbolts [6575] through the bearing housing or 
lantern. 
 
a) 
Slide the wet end towards the power end until 
the jackbolts [6575] engage in the recess 
provided for it. 
b)
Turn the jackbolts [6575] counterclockwise to 
allow the wet end to slowly engage into the 
power end. Alternate from one bolt to the other 
to prevent the unit from cocking. 
c)
Once the mating surfaces are in contact, install 
fasteners [6570.6] for Group A and 1 and 
[6570.8] for Group B and 2.
