Figure 8-85—Installing Preload Spring
1. Install the support on the up-
per end of the mast jacket and
install the four attaching support
screws. Torque screws to 25 in.
lb. Torque larger screws first.
2. Install the steering shaft into
the mast jacket.
3. Place the lower bearing on
upper portion of steering shaft.
4. Snap the lower ends of the two
tilt springs on the support spring
anchor.
5. Install the tilt lever into the
lock shoe release actuator.
6. Apply front wheel bearing lube
on lock shoes and on frictional
surfaces at actuator assembly in-
cluding surfaces where actuator
contacts support. Move the tilt
lever up slightly to prevent the
lock shoes from engaging the sup-
port pins, then install the actuator
assembly over the steering shaft
and feed horn contact ring wire
and direction signal switch con-
trol cable thru shift bowl. Posi-
tion a c t u a t o r a s s e m b l y on
support.
NOTE: Reassembly will be fa-
cilitated during seating of actua-
tor in support if the mast jacket
is supported in a vise and the
steering shaft is slightly up.
7. Apply lube to pivot pins. Align
the actuator assembly pivot pin
holes with the holes in the support
assembly and install pivot pins.
Pins should be flush with edge of
actuator.
8. Raise tilt release l e v e r and
position actuator at extreme up
position.
9. Connect the upper ends of the
two tilt springs using Installer
J-21181 (See Figure 8-86) to
lobes on actuator.
10. Install the turn signal actuator
yoke and detent spring. Be sure
yoke engages turn signal cable
operating lever in actuator.
11. Install upper bearing, inner
race, plastic bearing cap and horn
contact ring in original positions.
Replace cover by driving into po-
sition using a rubber mallet.
12. Install inner race seat, lock
plate and 12-sided nut.
13. Tighten 12-sided nut moder-
ately tight. Place steering wheel
on steering shaft and use Steering
Gear Tension Scale J- 544 on outer
edge of steering wheel to measure
pull required to turn steering
shaft. Pull required should not
exceed 35-40 inch ounces. Re-
tighten 12-sided nut as necessary.
Figure 8-86—Installing Tilt Springs
14. Coat horn contact ring with
lubriplate.
15. Install the tilt release and
direction signal turn levers in
actuator.
16. Install steering wheel. Para-
graph 8-5.
17. Install direction signal switch
as follows:
a. Position tilt wheel in full down
position. Locate switch pin in
center position.
b. Place direction signal lever in
off position, then install control
wire loop over switch operating
pin.
c. Attach cable wire clamp to
switch.
d. Assemble s w i t c h to mast
jacket and position switch bracket
as far forward (spring extended)
as possible and secure to mast
jacket.
18. Install spring and clamp onto
lower end of steering shaft and
compress spring to approximately
1/2 inch dimension.
19. Install lower coupling pinch
bolt and tighten to 25 ft. lbs.
20. On column shift steering col-
umns only adjust neutral safety
switch and transmission pointer
assembly (see Figure 8-87).
