adjuster screw.
76.If necessary back off sector shaft adjuster screw.
Tap cover in place to allow cover to joint fully
with casing.
NOTE: Before tightening fixings, rotate
input shaft to ensure sector shaft roller is
free to move in valve worm. If initial
resistance is left, turn adjuster screw
approximately two turns in a clockwise direction.
77.Fit cover bolts. Tighten to
75 Nm.

Adjusting sector shaft
NOTE: Refit drop arm and tighten nut
sufficiently to ensure that no backlash
exists between drop arm and sector shaft.
81.To set worm on centre, rotate input shaft to full
inner-lock (full right lock for a left hand drive
vehicle, full left lock for a right hand drive
vehicle). Rotate input shaft back towards centre
two full turns.
82.The box is now on centre and can be adjusted.

OVERHAUL 83.Hold input shaft and rock drop arm to establish
backlash is present. Continue rocking and slowly
turn sector shaft adjusting screw clockwise.
Continue rotating adjuster screw until backlash
has almost been eliminated.
84.Refit locknut and tighten.
NOTE: It is important steering box is
centralised before any adjustments are
made.
85.Check maximum rolling torque one and a quarter
turns either side of centre position, using a
torque wrench and spline socket LRT-57-025.
Rotate adjuster screw to obtain across centre
torque of 0.34 Nm plus torque figure at one and
a quarter turns. Tighten adjuster locknut to
60
Nm.
Adjusting rack adjuster.
86.Turn in rack adjuster to increase figure
measured in instruction 85. by 0.23 - 0.34 Nm.
The final figure may be less, but must not
exceed 1.35 Nm.
87.Lock rack adjuster in position with grub screw.
Tighten to
5 Nm.
Torque peak check
With input shaft rotated from lock to lock, rolling
torque figures should be greatest across centre
position and equally disposed about centre position.
The condition depends on value of shimming fitted
between valve and worm assembly inner bearing cup
and casing. The original shim washer value will give
correct torque peak position unless major components
have been replaced.Procedure
88.With input coupling shaft toward the operator,
turn shaft fully counter-clockwise.
89.Check torque figures obtained from lock to lock
using torque wrench and spline socket
LRT-57-025.
90.Check also for equal engagement either side of
centre.
Adjustments
91.Note where greatest figures are recorded
relative to steering position.If greatest figures are
not recorded across centre of travel (steering
straight-ahead), adjust as follows:
If torque peak occursbeforecentre position,addto
shim washer value; if torque peak occursaftercentre
position,subtractfrom shim washer value,
refer to
fitting valve and worm assembly
.
Shim washers are available as follows:
0.03mm, 0.07mm, 0.12mm and 0.24mm.
NOTE: Adjustment of 0.07mm to shim
value will move torque peak area by 1/4
turn on the shaft.
CAUTION: When reshimming valve and
worm, extreme caution must be exercised
to prevent seal damage during
reassembly.

SUPPLEMENTARY RESTRAINT SYSTEM

REPAIR ROTARY COUPLER CENTRALISE
Fitting a rotary coupler which has not been centralised
could result in tape breakage. If the tape is broken, a
new rotary coupler must be fitted.
Providing the removal procedure has been correctly
followed this operation should not be necessary. If
however there is evidence of tampering, it is
imperative that the coupler is centralised.
CAUTION: Ensure wheels are positioned
straight ahead before fitting the rotary
coupler.
1.Correctly fit rotary coupler to column switch
assembly but do not fit steering wheel or make
any electrical connections.
See rotary coupler.
2.Depress rotary coupler locking peg and without
using undue force, rotate coupler anti-clockwise
as far as inner tape will allow. Releasing peg will
lock coupler in its current position.
NOTE: Do not apply excessive force when
limit is reached as this may result in tape
breakage. If no limit can be found, tape
has already broken and rotary coupler must be
replaced.
3.Having turned rotary coupler fully anti-clockwise
to limit position, proceed to turn coupler 2.5 turns
clockwise to obtain central position. (Coupler will
normally rotate a full five turns from
anti-clockwise limit to clockwise limit).
4.Make necessary electrical connections and refit
steering wheel.
See steering wheel.
5.Refit driver's airbag module.See driver's
airbag module.
