terminals. The operator
should “map” the wire
terminal locations to ensure
correct rewiring. The
power cord should be
removed from the motor
housing (figure 5.5C).
6. Locate and remove the
pump casing bolts. These
bolts secure the motor and
motor adapter to the pump
casing (figure 5.5D).
7. Separate the motor and
motor adapter from the
pump casing to expose the
pump impeller (figure
5.5E). Remove the motor
and motor adapter from
the unit and place on a
workbench to continue the
procedure.
8. Locate and remove the
dust cap from motor end
to expose slotted motor
shaft. The motor shaft is
free to rotate, but must be
secured to remove the
impeller. To secure the
motor shaft, insert a flat
bladed screw driver in slot
to hold the shaft stationary
(Figure 5.5F).
9. Locate and remove impeller
locking screw (Figure
5.5G). Using a socket and
ratchet, the impeller
retaining screw can be
removed. Once the
retaining screw is removed,
the impeller can be
“unthreaded” from the
motor shaft to expose the
pump seal assembly.
10. Remove all seal parts
(Figure 5.5H). Note seal
component arrangement
to facilitate reassembly.
