stopped by the end of the worm. If
the balls are stopped by the end of
the worm, hold in those already posi-
tioned, and turn the worm in the
opposite direction. The filling of the
circuit can then be continued until
most of the balls are in place.
6.
Lay one half of the ball return
guide on the bench, and place the
remainder of the 31 balls in it. Posi-
tion the second half of the guide and,
holding the two halves together, plug
each open end with gear lubricant
so the balls will stay in the guide
when it is installed.
7.
Push the guide into the guide
holes of the ball nut, tapping lightly
with the wooden handle of a screw
driver if necessary.
8.
Assemble the second ball return
circuit in the same way as the first.
9.
Install the ball return guide
clamp and screws. Check the ball
nut to see that it rotates freely.
Torque the screw to specification.
10.
Coat the threads of the steering
shaft bearing adjuster, the housing
cover bolts, and the sector adjust-
ing screw with a suitable oil-re-
sistant sealing compound.
Do not
apply sealer to female threads, and
especially avoid getting any sealer
on the steering shaft bearings.
11.
Coat the worm bearings, sector
shaft bearing and gear teeth with
STEERING LINKAGE
The manual steering linkage (Fig.
12) consists of the
Pitman arm, the
steering arm-to-idler arm rod, the
steering idler arm, and the spindle
connecting rods (tie rods).
Do not
attempt to straighten bent link-
age; use new parts.
SPINDLE CONNECTING ROD
END REPLACEMENT
The spindle connecting rod ends,
which are threaded into the outer
ends of the rod sleeves, have non-
adjustable, spring-loaded ball studs.
A rod end should be replaced when
excessive looseness at the ball stud
is noticed.
1.
Remove the cotter pin and nut
from the worn rod end ball stud
(Fig.
12).
2.
Disconnect the end from the
spindle, connecting arm,
Pitman arm,
or idler arm as shown in Fig. 14.
3.
Loosen the connecting rod
sleeve clamp bolts, and count the
number of turns needed to remove
the rod end from the sleeve. Discard
gear lubricant ESW-M 1687-A.
12.
Clamp the housing in a vise,
with the sector shaft axis horizontal,
and position the steering shaft lower
bearing cup and the bearing in place.
13.
Position the steering shaft and
ball nut assembly in the housing.
14.
Position the steering shaft up-
per bearing on the top of the worm,
and install the steering shaft bearing
adjuster and cup. Install the lock nut
with the flat side against the bearing
adjuster and the letter "S" outward.
Leave the nut loose.
15.
After installing the steering
wheel nut on the steering shaft, ad-
just the worm bearing preload, using
an inch-pound
torque wrench to
check for specified preload.
16.
Position the sector adjusting
screw and the adjuster shim, and
check the end clearance which
should not exceed 0.002 inch be-
tween the screw head and the end of
the sector shaft. If clearance is great-
er than 0.002 inch, replace the shim.
17.
Thread the sector shaft ad-
justing screw into the housing cover.
18.
Install a new gasket on the
housing cover.
19.
Rotate the steering shaft until
the ball nut teeth are in position to
mesh with the sector gear, tilting the
housing so that the ball nut will tip
REPAIR
all rod end parts that were removed
from the sleeve.
All new parts
should be used when a spindle con-
necting rod end is replaced.
4.
Thread a new rod end into the
sleeve, but do not tighten the sleeve
clamp bolts at this time.
5.
Install the seal on the rod end
ball stud, insert the stud in the part
from which the old one was re-
moved, and 'install the stud nut.
Torque the nut to specification and
install the cotter pin.
6.
Check and, if necessary, ad-
just toe-in (Part 3-1).
After toe-in
is checked and adjusted, torque the
old sleeve clamp bolts to specifica-
tion. Add four pounds torque if
new bolts are used.
SPINDLE SLEEVE REPLACEMENT
A spindle sleeve should be re-
placed if it becomes worn or dam-
aged (Fig. 12).
Do not attempt to
straighten the sleeve if threaded
portion is damaged.

Install but do not tighten
the housing cover attaching bolts.
Do not tighten the cover bolts un-
til it is certain that there is some
lash between the ball nut and the
sector gear teeth.
24.
After loosely installing the sec-
tor shaft adjusting screw lock nut,
adjust the sector shaft mesh to the
specified mesh load, then tighten the
adjusting screw lock nut. Remove
the steering wheel nut.
1.
Remove the spindle connecting
rod ends as described in the previ-
ous sub-section.
2.
Screw the spindle rod ends
into the new sleeve the same num-
ber of turns as the ends that were
removed. Do not tighten the clamp
bolts at this time.
3.
After installing the seal on
the rod ends, position the sleeve
assembly on the
Pitman arm (or the
idler arm) and the spindle arm. Install
the attaching nut, torque it to speci-
fication, and install the cotter pin.
5.
Check and, if necessary, ad-
just toe-in (Part 3-1). After toe-in is
checked and adjusted, torque the
sleeve clamp bolts to specification.
