Lightly grease the O.D. of the seal retainer (74).
Insert the seal retainer into the gearcase (27), onto
the spindle sleeve (85) until the outside face of the
seal retainer is flush with the face of the gearcase.
Place the open end of the service fixture 61-10-0013
over the spindle sleeve and gently push the
retainer into the gearcase prior to installing
the retaining ring (50). Striking the
service fixture with a hammer
is not recommended,
doing so may cause
the seal retainer to
wedge in the
gearcase.
