Using the special tool, measure total rotation torque by
turning the pinion gear at a speed of one rotation per
4 to 6 seconds.
Standard value:
Total rotation torque: 0.6 – 1.5 Nm
Torque fluctuation: 0.5 Nm or less
2.
If the total rotation torque or torque fluctuation does not
meet the standard values, adjust by returning the rack
support cover within a range of 0 to 30
_
.
Caution
(1) Adjust around the maximum limit of the standard
values.
(2) See that no ratcheting or catching are present
when operating the rack towards the shaft
direction.
(3) Measure the total pinion torque through the whole
stroke of the rack.
3.
If the adjustment is impossible in the given range, check

BELLOWS BAND INSTALLATION
1.
Turn the adjusting bolt of the special tool to adjust the
opening dimension (W) to the standard value.
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.
NOTE
(1) The dimension (W) is adjusted by about 0.7 mm per
one turn.
(2) Do not turn the adjusting bolt more than one turn.
2.
Use the special tool to crimp the bellows band.
Caution
(1) Hold the rack housing, and use the special tool
to crimp the bellows band securely.
(2) Crimp the bellows band until the special tool
touches the stopper.
3.
See that the crimped width (A) meets 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.]
