must be free to turn with no perceptible end play to

inch loose. Three different thickness shims are
available to obtain the specified clearance.
(35) Start the cross shaft and adjuster screw into
bearing in the housing cover. Then, using a screw driv-
er through the hole in the cover, turn the screw coun-
terclockwise to pull the shaft into the cover.
(36) Install the adjusting screw lock nut, but do
not tighten at this time.
(37)
Rotate the wormshaft to centralize the ball nut.
(38) Place a new cover gasket on the housing cover.
(39) Carefully install the cross shaft and cover
as-
NOTE: The cross shaft and sector teeth should
be
coated with the steering gear lubricant before in-
stalling the cross shaft in the housing.
(40)
Make certain some lash exists between the
cross shaft sector teeth and the ball nut rack then
install and tighten the cover bolts to
25
foot-pounds.
Gear Installation
All Models Except AV2 Equipped with
273
Cu. In. V-8 Engine
(1)
Slide the steering column assembly upward to
where the column coupling will clear the end of the
wormshaft and permit installation of the steering
gear. Also make sure the clamp is in place on the
steering shaft coupling.
NOTE: On models equipped with 6 cylinder engines
the steering gear can be entered through the hood
opening. However, when installing the steering gear
in models equipped with
8
cylinder engines, limited
clearance makes it necessary to place the gear in po-
sition from underneath the vehicle.
(2)
Position the steering gear in position and install
the three mounting bolts.
(3) Tighten the mounting bolts to 55 foot-pounds
for AR1, AR2, AV1 and AV2 models and 80 foot-
pounds for AP1 and AP2 models.
(4)
With the master serration on the wormshaft
aligned with the notch mark on the coupling housing
slide the steering column assembly down far enough
to engage the column coupling with the wormshaft.
sembly into the steering gear housing (Fig. 5).
(5) Align the groove on the steering column coup-
ling with the groove in the wormshaft and install the
coupling bolt, washer and nut.
(6)
Tighten the nut to 30 foot-pounds.
(7)
While the jacket clamp bolts are loose, position
the jacket assembly
so
the steering shaft coupling is
centered at the midpoint of its travel.
The coupling travel midpoint can be determined
by a
3/16"
diameter gauge hole which is provided in
the steering shaft.
When the dimension from the top of the coupling
to the center of the gauge hole is
inch the coupling
is centered in its travel.
(8)
After centering the coupling, tighten the col-
umn jacket to instrument panel clamp bolts to
95
inch-pounds.
NOTE: On vehicles equipped with manual tranrmir-
sion and concentric shift linkage, it will
be
necer-
sary to readjust the length of the 1st and reverse
shift rod and the 2nd and 3rd shift rod after the
steering column assembly has been secured in posi-
tion. See "Manual Transmission Linkage Adjust-
ments."
(9) Turn the steering gear and steering wheel to
the midpoint of its travel.
(10) Adjust as necessary. See "Ball Nut Rack and
Sector Mesh Adjustment."
(11) Place the front wheels in the straight ahead
position
so
the master serrations in the steering gear
arm align with those on the steering cross shaft.
(12) Install the steering gear arm, lock washer and
nut on the cross shaft and tighten the nut to 120
foot-pounds.
(13) After the steering gear has been completely
installed, test the steering wheel to be sure
it
is cen-
tered in the straight ahead position. If
it
is found
to be off center with the wheels straight ahead, adjust
the tie rods to center the wheel. See Group
2,
"Front
Suspension.''
AV2 Models Equipped with

(1)
From under the vehicle position the gear on the
crossmember and install the three gear housing
mounting bolts. Tighten the bolts to 55 foot-pounds.
(2) Lower the engine on the front engine mount
pads and install the front engine mount stud nuts and
washers. Tighten the nuts to 75 foot-pounds.
(3) With the master serration on the wormshaft
aligned with the notch mark on the coupling hous-
ing slide the steering column assembly down far
enough to engage the column coupling with the worm-
shaft.
(4)
Move the coupling down the wormshaft until it
bottoms and install the bolt.
(5) Tighten the nut to 30 foot-pounds.
(6) While the jacket clamp bolts are loose, position
