Figure 13. Seal Removal
Install Seal and Bearing
1. Clean area in housing where seal outer diameter
(OD) seats. Apply a thin coat of Permatex®.
2. Inspect area of shaft where seal seats. Remove
any burrs or nicks with an emery cloth.
3. Place seal squarely on housing, place spring-
loaded lip down towards housing. Select a piece of
pipe or tubing with an OD that will sit on the outside
edge of the seal but will clear the housing. Tubing
with an OD that is too small will bow seal cage and
ruin seal.
4. Carefully press seal into housing, avoiding
distortion to the metal seal cage.
5. Slide bearing and spacer washer onto shaft and
secure with snap ring.
6. Insert shaft into motor housing and align splines.
