3. STEERING COLUMN ALIGNMENT.
(a) After adjustments have been made and
lock screw tightened, turn steering
wheel to see if any stiffness exists. If
so, steering gear has been adjusted
too tight or steering column is out of
alignment. Misalignment of the column
places a bend in the column, conse­
quently, the wheel tube must undergo
reverse bending stresses during each
revolution. This is a serious condition
and mustbe avoided. THE STEERING
COLUMN MUST NOT BE SPRUNG
IN ANY DIRECTION.
4. STEERING GEAR
FRONT WHEELS,
CONNECTION
WITH
(a) The steering gear should be connected
to the front wheels so as to obtain as
nearly as possible the specified turn­
ing radius on both left and right turns.
This is accomplished by turning the
steering wheel as far to the right as
possible, then rotate the wheel in the
opposite direction as far as possible
and note the total number of turns,
Turn the wheel back just onE?-half of
this total movement, thus placing the
gear in the mid'-position. With the
front wheels in position for straight­
ahead driving, it should then be pos­
sible to connect the drag link to the
ball on the end of the steering gear
arm without moving the gear to any
appreciable extent, If this cannot be
done, remove the arm from the steer­
ing gear, using a suitable puller, and
place it on the splined shaft in the
proper position. Otherwise it will not
permit the front wheels to swing equal­
ly to the left and right, Check steering
knuckle s top on front axle to make
sure that there is proper clearance
for the tire when turning at maximum
angle. Axle stops should also be set
out sufficiently to prevent steering
gear from lIbottoming", that is, to stop
the gear short of its absolute limit of
travel. If the gear is permitted to
bottom, damage to internal parts will
occur. Check to see if axle stops are
set to do this on both left and right
turns. See that steering gear housing
is filled with lubricant as recom­
mended in "Lubrication Section".
