Install bearing and seal pusher (T6) (3) as
follows:
NOTE
Correct bearing must be installed in
lug. Leading lug bearing is wider and
has smaller inside diameter. Bearing
markings must be next to threads on
lug after installation.

Coat bearing (4) and inside of lug (1 or 2).

Position identification side of bearing (2)
against bearing installation pilot (5).
NOTE

bearing (2) is against outboard, threaded side
of lug (3 or 4). Align matchmarks on bearing
with matchmarks on lug unless bearing is to
be rotated for longer service.

highest and lowest holes (7) are rotated 8 to
22 clockwise from vertical.
