ignition key cylinder operates properly look for the
following conditions.
(1) Look for rough areas or flash in the casting
and if found remove with a file (Fig. 10).
(2) Grease the lock plate actuator, lock plate, slider
and locking link.
REMOVAL
The ignition key must be in the key cylinder for
cylinder removal. The key cylinder must be removed
first before removing ignition switch.
(1) Remove key cylinder, (Refer to 19 - STEER-
ING/COLUMN/LOCK CYLINDER HOUSING -
REMOVAL).
(2) Remove lower steering column cover screws
and remove cover (Fig. 8).
(3) Remove ignition switch mounting screw (Fig.
13). Use tamper proof torx bit to remove the screw.
(4) Using a small screwdriver, push on locking tab
(Fig. 11) and remove switch from steering column.
(5) Disconnect two electrical connectors at rear of
ignition switch (Fig. 13).
INSTALLATION
The ignition key must be in the key cylinder for
cylinder removal. The key cylinder must be removed
first before removing ignition switch.
(1) Before installing ignition switch, rotate the slot
in the switch to the ON position (Fig. 12).
(2) Connect two electrical connectors to rear of
ignition switch. Make sure that locking tabs are fully
seated into wiring connectors.(3) Position switch to column and install tamper
proof screw. Tighten screw to 3 N´m (26 in. lbs.).

GEAR SHIFT LEVER
REMOVAL
(1) Support the steering column assembly as
shown in (Fig. 14) using a suitable size socket and
back-up support.
(2) Disconnect over drive switch wiring.
(3) Using a drift of the appropriate size drive the
knurled pin out of the steering column and gear shift
lever. Remove the gear shift lever from the steering
column assembly.
CAUTION: The pin can only be removed from the
direction shown (Fig. 14).
INSTALLATION
(1) Support the steering column using a suitable
size socket and back-up support.
(2) Install the gear shift lever into the steering col-
umn assembly. Align the pin holes in the gear shift
lever and the steering column assembly.CAUTION: The pin must be installed in the original
direction.
(3) Carefully Install the pin into the steering col-
umn assembly and through the shift lever. If the pin
binds check the alignment on the holes. Be sure pin
is fully installed into the steering column assembly.
(4) Connect over drive switch wiring.

WORM THRUST BEARING PRELOAD
(1) Mount the gear carefully into a vise.
CAUTION: Do not overtighten the vise on the gear
case. This may affect the adjustment
(2) Remove adjuster plug locknut (Fig. 5) .
(3) Rotate the stub shaft back and forth with a 12
point socket to drain the remaining fluid.
(4) Turn the adjuster in with Spanner Wrench
C-4381. Tighten the plug and thrust bearing in the
housing until firmly bottomed in the housing about
28-31 N´m (20-23 ft. lbs.).
(5) Place an index mark on the housing even with
one of the holes in adjuster plug (Fig. 6) .
(6) Measure back (counterclockwise) 18 mm (0.70
in) and mark the housing (Fig. 7) .
(7) Rotate adjustment cap back (counterclockwise)
with spanner wrench until hole is aligned with the
second mark (Fig. 8) .
(8) Install and tighten lock nut to 108 N´m (80 ft.
lbs.). Be sure adjustment cap does not turn while
tightening the lock nut.
PITMAN SHAFT OVER-CENTER PRELOAD
NOTE: Before performing this procedure, the worm
bearing preload adjustment must be performed.
(1) Rotate the stub shaft with a 12 point socket
from stop to stop and count the number of turns.
(2) Starting at either stop, turn the stub shaft
back 1/2 the total number of turns. This is the center
of the gear travel (Fig. 9) .(3) Place the torque wrench in the vertical position
on the stub shaft. Rotate the wrench 45 degrees each
side of the center and record the highest rotational
torque in this range (Fig. 10) . This is the Over-Cen-
ter Rotating Torque.
NOTE: The stub shaft must rotate smoothly without
sticking or binding.

(4) Rotate the stud shaft between 180É and 270É to
the left of center and record the left off-center pre-
load. Repeat this to the right of center and record the
right off-center preload. The average of these two
recorded readings is the Preload Rotating Torque.
(5) The Over-Center Rotating Torque should be
0.23-0.68 N´m (2-6 in. lbs.)higherthan the Preload
Rotating Torque.
(6) If an adjustment to the Over-Center Rotating
Torque is necessary, first loosen the adjuster lock
nut. Then turn the pitman shaft adjuster screw back
(COUNTERCLOCKWISE) until fully extended, then
turn back in (CLOCKWISE) one full turn.
(7) Remeasure Over-Center Rotating Torque. If
necessary turn the adjuster screw and repeat mea-
surement until correct Over-Center Rotating Torque
is reached.
NOTE: To increase the Over-Center Rotating Torque
turn the screw CLOCKWISE.
(8) Prevent the adjuster screw from turning while
tightening adjuster lock nut. Tighten the adjuster
lock nut to 49 N´m (36 ft. lbs.).
