Ibs.-ft. Every six months the
wheel bearings, grease seals and
axle spindles should be inspected
for damage (corrosion, etc.) or ex-
cessive wear. Replace any dam-
age.! or worn parts. Repack
wheel bearings. Use a wheel
bearing grease conforming to
specification MIL-G-10924 and
suitable for all ambient tempera-

Grease can be replaced in a
wheel bearing using a special fix-
ture or by hand as follows:
Place a spoonful of grease in the
palm of one hand and take the
bearing in the other hand. Push a
segment of the wider end of the
bearing down into the outer edge
of the grease pile closest to the
thumb. Keep lifting and pushing
the bearing down into the edge of
the grease pile until grease oozes
out both from the top and from be-

cap serves no purpose due to the tact
that there Is no way to force the

thoroughly pack the Inner and outer
bearing with grease and then to apply
only a very small amount of grease
Into the grease cap.
If bearing adjustment is required or the hub has
been removed foranyreason, the following pro-
cedure must be followed to ensure a correct
