In operation only when he tuyns the
wheel. and. therefore, he assumes
there cannot be much wear. A. q
matter Of fact. the steering PARTS are
constantly moving even whom you are
uriVen over what you consider q
smooth road. On a rough road, when
the steering wheel 10 held firm, there
10 considering amount of movement
to the rest Of the system. II 10 in.
teresting to watch this movement on
another car. It is because of this
constant moving OF the parts that at.
tention to fabrication is 90 necessary.
Dryness Of the steering knuckle pins
lsometimes called king pins, will result
IN hard steering, because the pins will
bind In the knuckies. Later on they
VIII be entirely too free In the
knuckles. with perhaps a binding
point at one position of the steering
wheel. knuckle pins should be oiled
daily. or II grease-graphite is used,
once every two weeks. or as expert.
Cnce dictates Is necessary.
A habit q great many owners have
is that Of turning the steering wheel
while the car Is standing still. This
puts a terrific strain on all the steer
ing parts and results In the develop
ment OF play In Q short time. Never
try to turn the front wheels except
when the car is moving. even though
II be very slow.
Steering Play Developed.
Once steering play has developed. II
multipiies rapidly owing to the sys-
tenn being operated In the reverse by
the front wheels. This will be noticed
mn ~ ffCf1I Io rlv LIB
the front wheels might take q notion
to wfggle from side to side rapidly.
While the average system does not
take into consideration the results Of
excessive wear. II In possible to pre-
vent this wiggiing by keeping the
steering connections tight. This re-
sistance offered to the front wheels
tends to keep them moving in .
straight line.
Adjustments of the steering system
should be made with some idea Of the
location Of the wear that h to be COM
rensated for. II the wear exists In
the steering knuckle pins. there u no
use adjusting the steering gears. Like
wise, II the drag link IL bsnt, thus
causing stiff steering. there II little
sense In doing anything but straighten
II. In making adjustment always
Jack UP front wheels 20 that you can
make different adjustments and try
each one. This also affords q means
Of disconnecting the drag link or tie
rod to locate the exact part that needs
adjustment. for sometimes the owner
finds difficulty In doing this.
Wear In the Gears.
Wear In the gears ID quito easy to
take up, a. there usually 10 an ad-
justing nut just above the gear
housing. This nut when turned gives
firmer mesh to the gears. In the
worm and wheel types Of steering only
one-half Of the worm wheel comes In
contact with the worm. After the
adjustment on this type has been
taken up as Tar as II will 60. 1t II ad-
yisable to use the other half of the
worm wheel. This II done by discon-
Meeting the steering arm and turning
the steering wheel around one-half
revolution. This brings the other haIf,
Of the worm wheel in mesh with the
worm and you have In effect Q new
steering gear. In disconnecting the
steering arm, mark the part from
pencil indicating it's position. Then
you will know more easily when you
have turned the worm around to its
new position. u.
In the screw and nut types there
are two general types, the sput nut
and the complete nut. In the split nut
type one-half the nut moves up while
the other half moves down. As they
do this they rock Q horizontal shaft
which imports the necessary motion
to the steering arm. In the complete
nut type. the nut travels UP and down
on the screw and In doing 20 operates
the steering arm by means of con-
Lecting link.
When either Of the screw types
becorn" 90 worn that the nut no
longes ds the screw but cocks at
one position, Il is q sign that q
new nut ought to be fitted.
Sometimes excessive strain will
cause tooth on the worn gear TO
chip, or portion Of the screw on
the other type. This will be felt
at the wheel and may cause binding
at one point In the steering.
Scrape Across Road.
Steering is, Of course. affected by
other things besides fabrication and
adjustment. II the front wheels are
not properly lined up they will have
q tendency to. scrape across the
road surface. and this gives the ef.
feet Of stiff steering gear. The
front tires should b kept wsll In
