SERVICE
MANUAL
8. When inspecting or replacing bearings, make
sure
the bearing
cone
(inner race) is free to creep
on spindle of steering knuckle. The
cones
are de-
signed to creep on the spindle In order to afford a
constantly changing load contact
between
the
cones
and
the roller bearings. Polishing the spindle or
applying
bearing lubricant
will
permit creeping and
prevent rust forming
between
cone
and spindle.
9. Be sure bearing parts have been thoroughly
cleaned and
air-dried
because bearing lubricant
will
not adhere to wet or oily surfaces.
10. Use a bearing packer if available and thor-
oughly pack both bearing assemblies with new high
melting point wheel-bearing lubricant. Remove any
excess
lubricant.
11. Apply a light coat of lubricant to spindle and
inside surface of wheel hub.
12. Place inner bearing in race of wheel hub and
install
a new grease seal.
13.
Clean
loose
material from brake drum with
compressed air. Be sure inner hub and bearings
are
covered. Inspect lining contact area for oil and
grease.
Clean

vent (such as denatured alcohol). Make sure wiping
cloth and fluid do not
become
loaded with grease
from
repeated use.
14. Inspect brake linings for oil and grease con-
tamination.
Clean
by wiping with a non-flammable,
non-toxic solvent (such as denatured alcohol). Sand
lightly to rough up surface of linings.
