d. If the impeller does not fit,
repeat steps a. and b. to deter-
mine the problem.
5. Place “O” ring (#7) into the “O”
ring groove in the motor bracket.
It is helpful to stand the motor and
pump assembly on end for this
procedure.
6. Remove the thru bolts installed
in 2b. Place the cover over the
motor bracket and install the four
(4) 3/8” X 4” bolts. Tighten the
bolts systematically, alternating
diagonally across the cover.
These bolts must be torqued to
about 20 ft. lbs. to obtain proper
performance.
7. After the bolts are “snugged up”,
make sure the impeller is not
binding by inserting a 5/32” hex
wrench into the locking collar and
moving it left to right. The shaft
should rotate with little or no re-
sistance. If the shaft will not turn,
loosen the bolts equally until the
impeller moves freely.
Proceed to section 4G Testing and
Final Adjustment.
4G Reassembly (T41- C15 and P15)
All parts should be visually inspected
and cleaned or replaced as outlined
in 4D above.
1. The stationary seat (#125) must
be installed in the motor bracket
before the bracket is installed on the
motor. To install the seat:
a. Place the motor bracket, face
up, on a flat surface.
b. To make the installation of the
seat easier, apply a thin coating
of compatible lubricant to the
elastomer portion of the seat
prior to installation.
c. Carefully press the seat,
smooth side up, into the seat
cavity of the motor bracket.
Care must be taken not to
damage the seat face. Thumb
pressure is usually sufficient to
install the seat.
2. Install the motor bracket.
a. While holding the motor bracket
with the outlet port facing up,
install two of the thru bolts into
the motor face, to temporarily
hold the motor bracket in place.
b. Slide the bracket back until
the feet are resting against the
motor face. Light tapping may
be necessary to seat the motor
bracket in the proper position.
3. Install the sleeve hub and rotating
element as a unit.
a. Place the sleeve in an upright
position with the smaller end
facing up.
b. Lubricate the motor shaft with
a small amount of glycol based
lubricant.
c. It is generally easier to remove
the entire head or sealing
assembly from the spring and
install it on the motor shaft.
This assembly lifts out of the
rotating element spring.
d. After removal, apply a thin layer
of lubricant to the elastomer
portion of the seal.
e. Holding the head assembly
between the thumb and index
finger with the sealing face
pointing toward the stationary
seat, slide the assembly over
the motor shaft until it rests
against the seat. Refer to
Figure 4-14. A slight twisting
motion will allow the assembly
to slide more easily.
