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 occurs before centre position, add to
shim washer value; if torque peak occurs after centre
position, subtract from 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.
