11. Install diaphragm spring into gear housing.
+Always install retainer, spring washer and diaphragm spring in
that order.
+Make sure convex end (painted white) of diaphragm spring
faces outward when installing.

16. Install boot bands.
+Securely install boot band to boot groove and clinch the root
section of the trapezoidal area.
+Make sure that there is a clearance of 3.5 mm (0.138 in) or less
at the clinched section of the boot band. Refer to the Figure at
left.
SST869C
+After installing gear in vehicle, make sure that the clinched
section of boot band is positioned toward the rear of vehicle (to
prevent interference with adjacent parts).

AdjustmentNJST0026Adjust pinion rotating torque as follows:
1. Set rack to the neutral position without fluid in the gear.
2. Coat the adjusting screw with locking sealant and screw it in.
3. Lightly tighten lock nut.
4. Tighten adjusting screw to a torque of 4.9 to 5.9 N´m (50 to 60
kg-cm, 43 to 52 in-lb).
5. Loosen adjusting screw, then retighten it to 0.2 N´m (2 kg-cm,
1.7 in-lb).
SST862CB
6. Move rack over its entire stroke several times.
7. Measure pinion rotating torque within the range of 180É from
neutral position.
Stop the gear at the point of maximum torque.
8. Loosen adjusting screw, then retighten it to 4.9 N´m (50 kg-cm,
43 in-lb).
9. Loosen adjusting screw by 50É to 70É.
SST713C
10. Prevent adjusting screw from turning, and tighten lock nut to
specified torque.

11. Check rack sliding force on vehicle as follows:
a. Install steering gear onto vehicle, but do not connect tie-rod to
knuckle arm.
b. Connect all piping and fill with steering fluid.
c. Start engine and bleed air completely.
d. Disconnect steering column lower joint from the gear.
e. Keep engine at idle and make sure steering fluid has reached
normal operating temperature.
f. Pull tie-rod slowly to move it from neutral position to±11.5 mm
(±0.453 in) at speed of 3.5 mm (0.138 in)/s. Check that rack
sliding force is within specification.
Average rack sliding force:
132 - 308 N (13.5 - 31.4 kg, 30 - 69 lb)
Maximum force deviation:
176 N (17.9 kg, 39 lb)
12. If rack sliding force is not within specification, readjust by
repeating adjustment procedure from the beginning.
13. If rack sliding force is still out of specification after
readjustment, gear assembly needs to be replaced.
