The pump motor housing contains a special lubricating oil.
Keep oil clean and free of water at all times.
NOTICE:
Whenever motor cover is being removed for ser-
vice, remove oil and replace with new oil at reassembly. Use
only oil listed in parts list (Part No. U197-8A). When filling
with new oil, DO NOT overfill. To allow room for expansion,
oil level with cold motor should be about 1/4’’ (6 mm) above
top of motor assembly.
Impeller and Seal Replacement
Risk of electrical shock. Disconnect electri-
cal power before doing any service work on pump!
Refer to assembly drawing.
Disassembly
1.
Unscrew hex-head cap screws, remove motor assembly
from volute and set it on its side in a clean area.
2.
Remove oil plug. Turn pump upside down to drain oil.
3.
Hold impeller; remove impeller nut and washer.
4.
Unscrew impeller (turn counter-clockwise) for cleaning.
5.
Loosen cord nut and gently pull cord assembly out from
motor cover. Disconnect wires from cord set (wires and
connector are color coded for reassembly).
6.
Unfasten socket head screws holding motor cover to seal
plate and remove motor cover.
7.
Remove rotating half of seal off of shaft.
8.
Cradle motor assembly so that it stands vertically with
motor shaft extending out of the bottom.
9.
Remove through bolts from motor assembly. Remove
motor and shaft from seal plate.
10. Working from back of seal plate, tap primary seal head
out of seal plate; thoroughly clean seat cavity.
Re-assembly
NOTICE:
Make sure that seal faces are clean and undam-
aged. Apply Permatex #2 or equivalent sparingly to outside
edge of seal body (with spring) Figure 1.
1. Press new seal body into cavity in seal plate (Figure 1).
2.
Reinstall motor and shaft to seal plate using the four
through bolts removed in step 10 under “Disassembly”.
NOTICE:
Do not overtighten through bolts!
3.
Slide new rotating half of seal onto shaft (Figure 2).
NOTICE:
Do not nick or scratch the silicon carbide seal
face when passing it over shaft shoulder. Seal faces must
be clean and undamaged or seal may leak.
4.
Reassemble impeller, washer, and impeller nut.
5.
Inspect O-Ring carefully; replace if damaged. If it is not
nicked or scratched, clean and reinstall.
NOTICE:
It is good practice to replace O-Ring each time
pump is serviced.
6.
Reconnect motor wires to connector. Reference color
code markings.
