INSTALLATION
1. Set front wheels and steering gear in straight
ahead position. Adjust tie rods if necessary to
obtain 0" -1/16" toe-in.
2. Attach front end of drag link to center steering arm
and rear end to the pitman arm.
WORM BEARING ADJUSTMENT
If end play exists in the worm bearings, the follow-
ing adjustment is necessary.
1. Disconnect drag link at pitman arm using tool
J-2781.
2. Loosen the four worm cover bolts about 1/8".
3. Use a knife to separate the top shim.
4. Remove one shim at a time and retighten cover.
5. After each shim is removed, turn steering wheel
through entire radius to determine if any stiffness
exists.
6. If stiffness is felt, replace shims unti1 steering
wheel turns freely.
7. Attach drag link to pitman arm.
ROLLER MESH INSPECTION
Improper mesh of roller with worm gear is indi-
cated by excess play or stiffness in the steering wheel.
Inspection for proper mesh should not be made until
worm bearing end pl ay and gear alignment have
been checked and corrected if necessary as follows:
1. Disconnect drag link at pitman arm.
2. Turn steering wheel to straight ahead position.
3. Shake pitman arm to determine amount of lost
motion. If lost motion exceeds 1/32", adjust roller
for proper mesh.
4. Connect pitman arm to drag link.
STEERING GEAR 130
ROLLER MESH ADJUSTMENT
1. Disconnect pitman arm from drag link.
2. Remove left side dust shield.
3. Turn steering wheel to straight ahead position.
4. Remove roller shaft adjustment screw lock nut
and lift lock plate clear of boss on housing.
5. Tighten roller shaft adjustment screw just
enough to eliminate lost motion at pitman arm.
(It is better to leave a slight amount of play -
not in excess of 1/32" - than to tighten too
much.)
6. Replace lock plate against cover in locked posi-
tion and replace and tighten lock nut.
7. Replace dust shield and connect drag link to
pitman arm.
IMPORTANT: Before connecting drag link
to pitman arm, place the front wheels on roller
plates and attach spring scale to tire tread.
Maximum pull required to turn wheels at any
point in the turning radius is 25 pounds. Any
excess pull indicates a binding in the front
suspension that should be corrected for proper
functioning of steering mechanism.
CENTER STEERING ARM
REMOVAL
1. Remove drag link at front by backing off plug.
2. Remove tie rod ends from steering center arm
using tool .T-2781.
INSTALLATION
1. When installing new bearings in center steering
arm bracket space as shown in Figure 6 and
apply pressure on outer race a t end carrying
manufacturers name and part number.
