Locate and remove impeller locking screw.
Using a socket and ratchet, the impeller
retaining screw can be removed. Once
removed, the impeller can be “unthreaded”
from the motor shaft to expose the pump
seal assembly.
11.
Remove all seal parts. Note seal component
arrangement to facilitate reassembly.
12.
Clean the motor shaft and lubricate with a
mild soap solution. Note: Oil must never be
used as a lubricant as it will damage the
rubber parts of the seal assembly.
13.
Install new stationary seal member in pump
casing cavity. Be certain the stationary seal
member is fully squared and seated in cavity.
14.
Slide the rotating member onto the lubricated
pump shaft. Be certain not to damage or tear
the rubber bellows assembly.
15.
Place the spring onto the rotating member.
16.
Align the tension spring and rotating member
before reinstalling the impeller. Be certain
the spring and rotating member are aligned
before the impeller is fully tightened and the
impeller retaining screw is reinstalled.
17.
Clean the pump casing, cavities, impeller
and O-ring before reassembly.
18.
Mate the motor and adapter to the pump
casing. Reinstall the 4 pump casing bolts.
