|
1.
caution |
- Be sure there is no ratcheting or
catching when operating
the rack towards the shaft.
- Measure the total pinion torque through
the whole stroke of the rack.
|
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]
2.
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.
|
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.

|
After installing the tie rod to the
rack, fold tab washer end (two locations) to tie rod
notch.
|

|
1.Turn the adjusting bolt of
special tool boot band crimping tool (MB991561) to adjust
the
opening dimension (W) to the standard value.
note |
The dimension (W) is adjusted
by approximately 0.7 mm per one turn.
|
note |
Do not turn the adjusting bolt
more than one turn.
|
Standard value (W): 2.9 mm <When
more than 2.9 mm>: Screw in the adjusting
bolt. <When less than 2.9 mm>: Loosen the
adjusting bolt.
|

2.
caution |
- Hold the rack housing, and use special
tool to crimp the
bellows band securely.
- Crimp the bellows band until special
tool touches the stopper.
|
Use special tool boot band crimping tool (MB991561)
to crimp the bellows band.
|
![](../../../img/37/ACX01166AB00ENG.png)
|
3.Check that crimped width
(A) is within the standard value. Standard
value (A): 2.4 -
2.8 mm <When more than 2.8 mm>: Readjust
the dimension (W) of step (1) to the
value calculated 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.] <When less than 2.4 mm>:
Remove the bellows band, readjust the dimension
(W) of step (1) to the value calculated by the following
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.]
