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.
11.
Clean motor shaft and lubricate with a mild
soap solution.
12.
Install new stationary seal member in pump
casing cavity (figure 5.5I). The operator must
be certain the stationary seal member is fully
squared and seated in cavity.
13.
Slide the rotating member onto lubricated pump
shaft (figure 5.5J). The operator must be certain
not to damage or tear rubber bellows assembly.
14.
Place the spring onto the rotating member.
15.
Align the impeller, spring and rotating member
before reinstalling the impeller (figure 5.5K).
The operator must be certain the spring and
rotating member are aligned before the impeller
is fully tightened and the impeller retaining
screw is reinstalled.
16.
Clean pump casing, cavities, impeller and
O-ring before reassembly.
17.
Mate the motor and motor adapter to the pump
casing. Reinstall the pump casing bolts.
18.
Reconnect the motor power cord and leads.
