8. Remove the rotating element from
the sleeve. Refer to Figure 4-3.
The element normally adheres
tightly to the sleeve and some
force may be necessary to remove
it. This is common and if care is
taken, the element can be
reassembled and reused. It is
recommended that a new
rotating element be used for
reassembly. DO NOT attempt to
remove the seal using a screw-
driver or other sharp object.
Extensive damage to the shaft,
sleeve, or element could occur.
9. 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).
10.Remove the seat portion of the
seal, Refer to Figure 4-6.
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.
d. Care must be taken with the
seats. They are often a brittle
material and are prone to
breakage. It is recommended
that a new replacement seat
be installed during reassem-
bly.
11.It is not necessary to remove the
locking collar (#14) on the motor
shaft unless motor repairs are
planned. Note the condition of the
setscrew in the collar and replce if
necessary. The two studs (#18) may
also be left in the motor face.
4C Disassembly (C15 and P15)
The following tools and equipment are
needed for disassembly of C15 and
P15 units:
1. Soft plastic or wooden mallet.
2. 9/16" wrench or socket.
3. Two 10" or larger adjustable
wrenches.
4. Penetrating oil.
5. 1" wood dowel ( Approx. 6" long).
6. Thin blade screwdriver.
7. Two large blade screwdrivers.
8. Cealube G or similar glycol base
lubricant. (DO NOT use petroleum
products.)
To disassemble the pump:
Refer to Figures 4-11 and 4-12 for
reference to the numbered parts in the
disassembly below.
1. Remove all liquid from the pump.
2. Remove the two (2) 3/8" nuts (#20),
and the two (2) 3/8" X 4" bolts (# 19)
from the cover. (#2)
3. Remove the cover. In some cases,
light tapping with a plastic or wooden
mallet on the outside diameter of the
cover may be required to loosen it
from the motor bracket. Care should
be taken if a screwdriver is needed
to pry between the cover and motor
bracket. Damage to the “O” ring (#7)
and/or impeller can result.
4. Remove the impeller (#11), refer to
Figure 4-7. The impeller is a slip fit
and, under normal conditions, can
be removed by gently tapping on the
end of the shaft sleeve with a mallet.
Leave the impeller key (#23) in
Figrue 4-7
Figure 4-6
place. Striking the sleeve too hard
could damage the seat or rotating
element.
5. Remove the impeller drive hub,
Refer to Figure 4-8. Two (2)
adjustable wrenches are used to
remove the impeller drive hub
(#14).
a. Adjust one wrench to fit over
the sleeve and engage the
impeller key. Adjust the second
wrench to fit the impeller nut
(#15).
b. Holding both wrenches, turn the
impeller nut counter-clockwise.
c. After the impeller nut is re-
moved, the impeller drive hub
can be removed.
d. The hub is keyed and can be
removed using two large bladed
screwdrivers.
e. Insert the blades of the screw-
drivers between the
springholder on the rotating
element and the shoulder of the
hub.
f. Holding the screwdrivers at
approximately 3 o’clock and 9
o’clock, push the handles in
toward the motor body, using
the motor bracket for leverage.
Refer to Figure 4-9. This
procedure usually does not
require excessive force. Care
should be taken not to damage
the hub or motor shaft.
6. Remove the rotating element from
the shaft. The element normally
adheres tightly to the motor shaft
and some force may be necessary
to remove it. This is common and
if care is taken, the element can
be reassembled and reused. It is
recommended that a new
