DJUSTMENT
-
Fr
equently one should jack up each
front
wheel,
try
moving the wheel
fr
om side to side
and
if even the slightest
movement is
pr
es
ent
between the wheel and hub remove the hub cap and pull the
cotter pin. Then
tight
en the
adjusting
nut
while
at
the same
tim
e
turning
th
e wheel
by hand until
slight
binding is felt.
Th
e nut should
th
en be backed off until the cot-
ter pin will go in either the horizontal or ve
rt
ical hole in the spindle.
If
it happens
that
the binding is noticed just when t he cotter pin is in line with one castellation it
is b
ett
er
to back the
nut
off
until the next castellation is in line with the other
cott
er
pin hole to
pr
event the bearing from being too
tight
. Be sure to use a new
co
tt
er pin if any cracking is presen
t.
BE CAREFUL to keep d
irt

atter
out
of
th
e grease or hub cap, which may now be assembled. Occasionally
one should go ov
er
the
nuts
on the hu bs, radius rod end
and
st
e
ering
arms
to see if
they are tight.
