rotating element be used for
reassembly. DO NOT attempt
to remove the seal using a
screwdriver or other sharp object.
Damage to the shaft or element
can occur.
7. Before the motor bracket (#1) can
be removed, the four (4) “O”rings
(#8), located on the upper left
and right studs must be removed.
a. Gently tap on the back of the
motor bracket, alternating
between the left and right side,
until the motor bracket moves
approximately 1/4".
b. Tap the motor bracket face to
move it back to its original
position.
c. Remove the "O" rings by
sliding them off the studs.
d. Slide the motor bracket straight
off. Do not attempt to remove
the motor bracket without first
removing the "O" rings (#8).
8. Remove the seat portion of the
seal. Refer to Figure 4-10.
a. Place the motor bracket face
down on a flat surface.
b. Look into the opening in the
center of the bracket, you will
see a portion of the seat.
c. Insert the 1" dowel, and very
gently, tap the seat until it
drops out. Care must be taken
with the seats. They are often
a brittle material and are prone
to breakage. It is recom-
mended that a new
replacement seat be installed
during reassembly.
4D Inspection of Components
Thoroughly clean all parts. All
components should be examined for
wear and corrosion. Replace any
parts that show visible wear. If the
pump was not producing sufficient
pressure or capacity, the clearances
between the casing and impeller
probably exceed the maximum
allowable clearance. At minimum
the impellers should be replaced in
this case. If the total side running
clearance for an impeller exceeds
.007", it is unlikely that pump
performance will reach that of a new
pump except at lower discharge
pressures.
The “O” rings and other elastomeric
components should be replaced if
they have been deformed or cut.
If seal components must be reused,
