6.9 Containment Shell [3500] Repair
Unless there is visual damage to the
particulate control ring [1500.2], removal is not
necessary and is not part of the normal inspection
procedure. If the particulate control ring [1500.2] is
damaged, it must be replaced.
6.9.1 Particulate Control Ring [1500.2] Removal
a) With small channel lock pliers, grip the old
particulate control ring near one of the notches
and pull it out.

particulate control ring with the containment
shell’s molded keys and press in place.

6.9.3 O-Ring [4610] Installation
a) Check the o-ring [4610] for dirt or deformation
before placing on the containment shell [3500].
Replace the o-ring if necessary.
b) Secure the containment shell [3500] composite
side down. An empty adapter [1340] works well
to hold the containment shell [3500] in place if
nothing else is available.
c) Attach one side of the o-ring [4610] around the
containment shell [3500] rim.
d) Slide your index fingers around the containment
shell [3500] on the o-
ring’s [4610] surface, forcing
it down into position while holding it with your
thumbs. The o-ring [4610] will snap into place.

6.10.1 Bushing Removal
This procedure requires 100 mm (4 in.)
length of 3/4 in. Schedule 40 PVC Pipe.
Make sure the bushing removal tool is
perfectly centered to prevent damaging the inside of
the impeller [2200]. We recommend placing a shop
towel under the impeller [2200] to prevent damage to
the SiC bushing [3300] when it falls free.
a) Center the impeller on an arbor
press, wear ring [3043] side up.
b) Center the PVC bushing tool on the bushing
[3300].
c) Place something soft such as a shop towel
underneath the impeller [2200] to catch the
bushing [3300] as it falls.
d) Carefully press the bushing [3300] down until it
dislodges and falls from the impeller [2200].
