Stator Assembly
NOTE: Seals, bearings, and o-rings should be replaced if removed. Heat the impeller housing evenly with a heat
gun to ease removal of bearings in next step. Remove tail cone O-ring before applying heat To ease installation,
wrap bearings in wax paper and chill in a freezer for 30 minutes or longer. Warm the impeller housing evenly with
a heat gun or a propane torch. DO NOT OVERHEAT.
1. Press or drive bottom bearing into place until it bottoms
against the shoulder in the pump housing. Apply
grease to center bearing spacer and install. Verify that
bearing spacer is centered, and install second bearing.
CAUTION:
Do not drive on the inner race. Bearing damage
will result. Drive on outer race only.
2. Place impeller spacer onto inner race of front bearing.
3. Apply marine grease to seal lips and also between the
two seals. Install two new oil seals over impeller
spacer with lips up and visible (toward impeller). Press
seals to bottom of chamfer on seal bore (about 1/8"/.32
cm beyond end of bore).
WARNING: Never allow the impeller spacer to push up
through the two seals when inserting the stub shaft.
If spacer pushes though seals, the seal lips will be
compromised and allow water into bearing housing.
4. Grease and install two new O-rings on stub shaft.
Mount stub shaft flats in a vise. Grasp stator assembly
with thumbs over impeller spacer. Carefully lower
assembly over stub shaft. Verify that stub shaft has
not pushed impeller spacer up through seals.
NOTE: If impeller spacer has pushed up through
seals, push into place slowly and carefully to prevent
dislodging seal springs.
5. Hand thread impeller onto stub shaft.
