Before reinstalling the locking tabs one of the tabs will need to be
shortened (see Fig. 9.) to avoid contacting the seal housing.
NOTE : There should be clearance between the locking tab
and the base of the locking tab slot in the seal
housing (see Fig. 10.).

Install the spring clip by first hooking both ends of the clip into the
small aligned cutouts of the seal housing and the adjuster nut, and
then snapping the clip into the groove of the seal housing using a
screwdriver. (Fig.11.)
Figure 11.
Check that the seal housing is now secured from rotating and that it
is still sitting flat against the adjuster nut.
