Manual Steering Gear - Jeep J-10 Series 1982 Technical & Service Manual

2K-2 MANUAL STEERING GEAR
(8) Install socket and inch-pound torque wrench on
steering wheel nut.
(9) Measure worm bearing preload by rotating
steering wheel through 90° arc (1/4 turn). Preload
should be 5 to 8 inch-pounds (0.6 to 1 N«m).
NOTE: Steering column misalignment or damage will
affect torque readings. If rotating torque is excep
tionally high, check the column alignment. If alignment
is correct, remove the gear, determine the problem area,
and repair as necessary.
(10) If preload adjustment is necessary, loosen worm
bearing adjuster locknut and turn adjuster clockwise to
increase preload or counterclockwise to decrease
preload.
(11) When desired preload is obtained, tighten ad
juster locknut to 90 foot-pounds (122 N»m) torque and
check preload again. Correct preload as necessary.
(12) Adjust pitman shaft overcenter drag torque.
CAUTION: Do not attempt to adjust pitman shaft
overcenter drag torque until after worm bearingpreload
has been adjusted.
(13) Rotate steering wheel slowly from stop-to-stop
and count total number of steering wheel turns.
(14) Turn steering wheel back 1/2 total number of
turns to place gear on center; then turn wheel 1/2 turn
off center.
(15) Install socket and inch-pound torque wrench on
steering wheel nut.
(16) Measure torque required to turn gear through
center of travel (this is overcenter drag torque). Drag
torque should equal worm bearing preload torque plus 4
to 10 inch-pounds (.5 to 1 N«m) but must not exceed total
of 18 inch-pounds (2 N»m).
Example:
Worm bearing preload is adjusted to 6 inch-pounds
(0.7 N«m) torque. Over center drag torque is adjusted to
7 inch-pounds (0.8 N»m) in addition to worm bearing
preload. This makes a total of 13 inch-pounds (1 N»m)
which is acceptable.
(17) If adjustment is required, loosen pitman shaft
adjusting screw locknut and loosen or tighten adjusting
screw to obtain desired drag torque.
(18) Tighten pitman shaft adjusting screw locknut to
25 foot-pounds (34 N«m) after adjusting drag torque and
recheck drag torque again. Correct adjustment if
necessary.
(19) Install pitman arm. Index arm to shaft using
alignment marks made at disassembly.
(20) Tighten pitman arm nut to 185 foot-pounds (251
N«m) torque and stake nut to shaft threads in one place.
(21) Lower vehicle.
(22) Correct steering wheel-to-steering shaft align
ment if necessary and install horn button cover.
Pitman Shaft Seal Replacement
(1) Raise vehicle.
(2) Place front wheels in straight-ahead position.
(3) Mark pitman arm and shaft for assembly
reference.
(4) Remove pitman arm using Puller J-6632 (fig.
2K-2).
(5) Remove seal using pointed tool or screwdriver
with small blade.
(6) Inspect condition of gear lubricant. If con
taminated and full of metal particles, remove and over
haul gear.
(7) Wrap pitman shaft splines with shimstock to
protect replacement seal during installation.
(8) Lubricate lip of replacement seal with chassis
lubricant, slide seal over shimstock and into seal seat in
gear housing. Complete seal installation by tapping seal
into place using small plastic mallet.
(9) Install pitman arm on shaft. Align arm and
shaft using reference marks made at disassembly.
(10) Tighten pitman arm nut to 185 foot-pounds (251
N«m) torque and stake nut to shaft threads in one place.
(11) Lower vehicle.
Side Cover and Gasket Replacement
(1) Raise vehicle.
(2) Remove pitman shaft adjusting screw locknut.
(3) Remove side cover attaching bolts.
(4) Turn pitman shaft adjusting screw clockwise to
remove cover from screw.
(5) Inspect condition of gear lubricant. If con
taminated and full of metal particles, remove and over
haul gear.
(6) Coat replacement side cover gasket with chassis
lubricant and position gasket on replacement side cover.
(7) Slide pitman shaft adjusting screw out of T-slot
in pitman shaft. Do not lose adjusting screw shim.
(8) Thread adjusting screw into side cover to depth
of 2-3 threads. Turn screw counterclockwise to start it
into cover.
(9) Install adjusting screw in pitman shaft T-slot.
align bolt holes in cover and gear housing, and turn
adjusting screw counterclockwise until side cover seats
against housing.
(10) Install and tighten side cover attaching bolts to
30 foot-pounds (41 N#m) torque.
(11) Install pitman shaft adjusting screw locknut
finger-tight only.
(12) Adjust worm bearing preload and pitman shaft
overcenter drag torque.
(13) Check and correct gear lubricant level as
necessary.
(14) Lower vehicle.
