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.

5. Install new capacitor. See below for electrical connec-
tions to capacitor.
6. 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.
7. Reinstall capacitor cover, feeding wire through connector
hole, then reconnect cord wires to connector. Reference
color code markings.

allow room for expansion, oil level with cold motor should
be about 1/4’’ (6 mm) above top of motor assembly.
