POWER STEERING GEAR
ASSEMBLY
1.
Apply Genuine NISSAN PSF or equivalent to O-ring. Put an O-ring into rack Teflon ring.
2.
Heat rack Teflon ring to approximately 40
°
C (104
°
F) with a
dryer. Assemble it to mounting groove of rack.
3.
To fit rack Teflon ring on rack, use rack Teflon ring installation
tool (SST) from tooth side. Compress rim of ring with the tool.
4.
Apply Multi-purpose grease or equivalent to rack oil seal. Insert
rack to gear housing assembly.
CAUTION:
●
When inserting rack, do not damage retainer sliding part.
If it is damaged, replace gear housing assembly.
●
When unstring rack, do not damage cylinder inner wall. If
it is damaged, it may cause oil leaks. Replace gear hous-
ing assembly.
●
Attach rack oil seal. Both inner lip and outer lip should
face each other.
a.
To avoid damaging inner rack oil seal, wrap an OHP sheet
[approximately. 70 mm (2.76 in)
×
100 mm (3.94 in)] around rack
tooth. Place oil seal on sheet. Then, pull oil seal along with OHP
sheet until they pass the toothed section of rack, then remove it.

b.
Insert rack oil seal (inner) to piston (rack Teflon ring) position
and push retainer to adjust screw side with fingers lightly, and
then make rack move in gear housing assembly, install rack oil
seal (inner) to fit in with gear housing assembly.
c.
When installing outer rack oil seal, cover the end of rack with an
OHP sheet [70 mm (2.76 in)
×
100 mm (3.94 in)]. It will avoid
damaging rack oil seal. Then place oil seal on sheet. Pull rack oil
seal along with OHP sheet until they pass rack end. Then
remove OHP sheet.
d.
Install end cover assembly to rack, move it to gear housing
assembly.
5.
Using a 42 mm (1.65 in) open head (suitable tool), tighten end
cover assembly at the specified torque.
CAUTION:
Do not damage rack surface. If it is damaged, it may cause
oil leaks. Replace rack assembly.
6.
After tightening end cover assembly, caulk cylinder at one point
as shown in the figure using a punch. This will prevent end cover
from getting loose.
7.
Apply Genuine NISSAN PSF or equivalent to O-ring. Install O-
ring to gear housing assembly.
8.
Install gear sub-assembly to gear housing assembly.
9.
Install power steering solenoid valve to gear sub-assembly (with
EPS).

10. Decide neutral position of rack gear.
11. Install the projection part (Tip) of rear cover cap to gear sub
assembly as shown in the figure.
12. Apply thread locking adhesive (Three Bond TB1111B or equiva-
lent to the thread of adjusting screw to the adjusting screw
height from gear housing assembly. The adjusting screw height
is the same as it was measured in the overhaul in advance.
13. Rotate pinion ten times whole range of rack so that parts get to
fit with each other.
14. Measure pinion rotating torque within from – 180
°
to + 180
°
make preload gauge (SST) and torque adapter (SST) in rack
neutral position, then hold preload gauge (SST) at maximum
torque.
15. After loosening adjusting screw once, tighten it again with torque
of 4.9 - 5.9 N·m (0.50 - 0.60 kg-m, 44 - 52 in-lb). After that
loosen it within from 20
°
to 40
°
.
16. Measure pinion rotating torque within torque adapter (SST) and
preload gauge (SST), then confirm whether its reading is within
the specified value. If the reading is not within the specified
value, readjust screw angle with adjusting screw. Change gear
assembly to new one, if the reading is still not within the speci-
fied value or the rotating torque of adjusting screw is less than 5
N·m (0.51 kg-m, 44 in-lb)

17. Turn pinion fully to the end of the left with tie-rods to rack.
18. Set dial gauge to rack as shown in the figure. Measure vertical
movement of rack when pinion is turned counterclockwise with
torque of 19.6 N·m (2.0 kg-m, 14 ft-lb). Check reading is within
the specified value. If reading is outside of the specification,
readjust screw angle with adjusting screw. If reading is still out-
side of specification, or if the rotating torque of adjusting screw is
less than 5 N·m (0.51kg-m, 44 in-lb), replace steering gear
assembly.
19. Install large-diameter side of boot to gear hosing assembly.
20. Install small-diameter side of boot to the mounting groove of
inner socket.
21. Install boot clamp to the small-diameter side of boot.
22. Install boot clamp to the large-diameter side of boot.
a.
Tighten large-diameter side of RH/LH boot with boot clamp
(stainless wire).
b.
After wrapping clamp around boot groove for two turns, insert
screwdriver in loop on both ends of wire. Twist 4 to 4.5 turns
while pulling with a force of approx. 98 N (10 kg, 22.1 lb).
c.
Twist boot clamp as shown in the figure, pay attention to rela-
tionship between winding and twisting directions.
1.71 - 2.34 N·m (0.18 - 0.23 kg-m, 16 - 20 in-lb)
