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.
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 tighten and the impeller retaining screw is
reinstalled.
