allowed body to shift. Also check the serrations
on pitman shaft; if serrations are twisted, re-
place the shaft.

7. When worm thrust bearing adjustment is
.ompleted,
check load on bearings by applying
kale J 544-A to a spoke at the rim of steering
"heel and pulling at 90 degrees to spoke, figure
'-7,
with
wheel
turned to near one extreme
iosit ion . The pull required to keep wheel
turn-
ng should be between
%
and
llfs
pounds. Re-
idjust
to within these limits if necessary.
8. Turn steering wheel from one extreme
iosition
to the other while counting the
turns,
hen turn wheel back one-half the total number
-f turns. This pla ces steering gear on the "high
ioint" at which no lash
should
exist between
'all nut and pitman shaft teeth. The lower
poke of wheel should point straight down, or
lot over
%"
to either side of straight down
osition.

lock wise until lash
between
ball nut and
p
it-
ran shaft teeth is just removed. Work pitman
.r rn back and forth to feel for lash. After tight-
ning adjusting screw lock nut, rotate steering
Theel back and forth through the "high point"
ange and check for tight spots. Check pull at
Theel with Scale J 544-A as described above.
The
pull
required to keep wheel moving through
"high
point" should be between
2
and
2%,
pounds. Readjust if necessary to remove tight
spots and obtain specified load at wheel rim.
NO'rE:
If lash cannot be removed at "high
point," or if gear load varies greatly and feels
rough, the gear assembly should
be removed
for inspection of internal parts (par.
7-8
and
7-9).
10. Connect steering tie rod to pitman arm,
being careful to properly seat the bearings
around ball stud. Make sure that the pressed
steel dust cover properly covers opening around
ball stud. See figure 7-4. Turn the tie rod plug
up solid then back off two turns and install
cotter
pin.
11. Road test car for ease of steering. If
steer ing gear was adjusted to specified load
limits and hard steering exists, the front sus-
pension members should be checked for lubri-
cation and alignment and tire inflation pres-
sures should be
checked.
When car is moving
straight ahead, the lower spoke of steering
wheel should be straight down, or not over
%"
to either side of straight down position. If
lower spoke is too far to either side, check
steering wheel for proper position on steering
shaft (par. 7-6) and check tie rods for equal
adjustment and toe-in (par. 6-30). It is impor-
tant to have the steering gear in the no-lash
range when car is moving straight forward.

ADJUSTM EN T OF STEERING WHEEL
HEIGH T
a.
1948
Models
On 1948 Models, the steering wheel cannot be
r
aised
from the production setting but it can be
lowered approximately 11;16" by installation of
two special spacers between the steering column
bracket and the lower flange of instrument
panel, and using longer bracket bolts.
Two column bracket spacers,
14"
thick, and
t
hree
bracket bolts of different lengths are in-
cluded
in the spacer package listed under
Group
6.764. Figure 7-8 shows the proper
len gth
of
bolt to use on the right and
left side of
bracket
for each
model.
b.
1949
Model
s
On 1949 Models, the steering wheels on Series
50-70 can be raised from the production set-
ting; however, the increased height may affect
visibility for the average driver. The Series 70
steering wheel can also be lowered from the
production setting.
