torque.
Standard value:
From
0-90°0.6-l .3 Nm (5-11 in.lbs.1From
90°-650°0.2-1.0 Nm (2-9 in.lbs.1
NOTE
Measure the pinion torque through the whole stroke of the rack.If the measured value is not within the standard range, first
adjust the rack support cover, and then check the total pinion
torque again.If the total pinion torque cannot be adjusted to within the
standard range by adjusting the rack support cover,
,check the
rack support cover, rack support spring, rack support and
replace any parts necessary.
CHECK THE TIE ROD FOR SWING RESISTANCE
