CAUTION
•Be sure there is no ratcheting or catching
when operating the rack towards the shaft.

AC100274 AB
MB991006
Measure the total pinion torque through the
whole stroke of the rack.
1. Using special tool preload socket (MB991006),
rotate the pinion shaft at the rate of one rotation in
4 to 6 seconds to check the total pinion torque and
the change in torque.
Standard value:
Total pinion torque: 0.8 − 2.1 N⋅m
[Change in torque: 0.6 N
⋅m or less]
Total pinion torque: 0.7 − 2.1 N⋅m
[Change in torque: 0.6 N
⋅m or less]
CAUTION
When adjusting, set at the highest value of the
standard value range.
NOTE: If the total pinion toque cannot be adjusted
to the standard value within the specified return
angle, check the rack support cover components
and replace any parts if necessary.
2. If the total pinion torque or the change in torque is outside the standard value, move the rack support
cover 0
− 30°, and adjust the pinion torque again.
>>L<< TAB WASHER/TIE ROD

1. Turn the adjusting bolt of special tool boot band
crimping tool (MB991561) to adjust the opening
dimension (W) to the standard value.

POWER STEERING GEAR BOX AND LINKAGE
POWER STEERING37-34
NOTE: The dimension (W) is adjusted by approxi-
mately 0.7 mm per one turn.
NOTE: Do not turn the adjusting bolt more than
one turn.
Standard value (W): 2.9 mm
: Screw in the
adjusting bolt.
: Loosen the
adjusting bolt.
CAUTION
•Hold the rack housing, and use special tool to
crimp the bellows band securely.

3. Check that crimped width (A) is within the
standard value.
Standard value (A): 2.4 − 2.8 mm
: Readjust the
dimension (W) of step (1) to the value calcu
-
lated by the following equation, and repeat
step (2).
W = 5.5 mm − A [Example: if (A) is 2.9 mm,
(W) is 2.6 mm.]
: Remove the bel-
lows band, readjust the dimension (W) of
step (1) to the value calculated by the follow
-
ing equation, and use a new bellows band to
repeat steps (2) to (3).
W = 5.5 mm − A [Example: if (A) is 2.3 mm,
(W) is 3.2 mm.]
