21. Install boot clamp to boot of the large-diameter side.
a.
Twist boot clamp (stainless wire) of the large diameter side for
LH/RH boots.
b.
After twisting 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.
d.
Bend the twisted wire to radius direction of rack, then confirm
the twisted point with clamp faces in the opposite direction to
adjusting screw within 90
°
as shown in the figure.
e.
After twisting wire 4 to 4.5 turns, bend cut end of wire. Cut end of
wire should not touch boot. Be sure wire end is at least 5 mm
(0.20 in) away from clearance for tube.
22. Install new O-ring to sub-gear assembly and install EPS sole-
noid valve to it, then tighten bolts at specified torque.
23. Install cylinder-tubes to gear housing assembly.
Tighten flared nuts at specified torque.

24. Install lock nut and outer socket to inner socket, then tighten lock
nut temporarily until length of tie-rod reaches to specified value.
On specified tightening torque with lock nut, refer to
.
NOTE:
Perform toe-in adjustment after this procedure. Length achieved
after toe-in adjustment is not necessarily value given here.

CHECKING RELIEF OIL PRESSURE
Before starting work, confirm belt tension is proper.
1.
Connect oil pressure gauge (special service tool) and oil pres-
sure gauge adapter (special service tool) between oil pump dis-
charge connector and high pressure hose and then bleed air
from the hydraulic circuit.
2.
Start engine. Allow engine to run until tank temperature reaches
50 to 80
°
C (122 to 176
°
F).
WARNING:
●
Warm up engine with shut-off valve fully opened. If
engine is started with shut-off valve closed, fluid pres-
sure in power steering pump increases to maximum. This
will raise fluid temperature excessively.
●
Be careful not to contact hose with belt when engine is
started.
3.
With engine at idle, close oil pressure gauge valve (special service tool) and read the relief oil pressure.
CAUTION:
Do not close shut-off valve of pressure gauge for more than 10 seconds.
4.
After measurement, open valve slowly.
●
If relief pressure is outside the specification, disassemble and service oil pump. Refer to
5.
After inspection, remove oil pressure gauge (special service tool) and oil pressure gauge adapter (special
service tool) from the hydraulic circuit, add fluid and bleed air from the hydraulic circuit thoroughly.
Refer to
PS-6, "Air Bleeding from Hydraulic System"

REMOVAL
1.
Remove undercover.
2.
Remove power steering oil pump belt from auto tensioner. Refer
to
3.
Loosen hose clamp from suction hose and remove suction hose
from power steering pump, then drain fluid. Refer to
SGIA0457E

4.
Remove joint, then drain fluid. Refer to
.
5.
Remove oil pump together with oil pump bracket. Refer to
INSTALLATION
Install oil pump with reverse order of the removal. After installation, bleed air. Refer to
NOTE:
Adjustment of belt tension is no necessary because engine of this model equips auto tensioner.
