POWER STEERING GEAR AND LINKAGE
ASSEMBLY
1. Apply recommended fluid to O-ring B. Put an O-ring B into a rack Teflon ring.
2. Heat rack Teflon ring to approximately 40°C(104°F) with a
dryer. Assemble it to mounting groove of rack assembly.
3. Install the Teflon ring correcting tool [SST: KV489Q0020] (A)
from tooth side of rack to fit rack Teflon ring (1) on rack. Com-
press the ring with tool.
4. Apply recommended grease to rack oil seal. And install rack oil
seal in the following procedure. Then assemble rack assembly
to gear housing assembly.
CAUTION:
lInstall rack oil seal in a direction so that the lip of inner oil
seal and the lip of outer oil seal face each other.
lDo not damage retainer sliding surface by rack assembly.
Replace gear housing assembly if damaged.
lDo not damage gear housing assembly inner wall by rack
assembly. Gear housing assembly must be replaced if
damaged because it may cause fluid leakage.
a. Wrap an OHP sheet [approximately 70 mm (2.76 in)´100 mm
(3.94 in)]. Around rack assembly teeth to avoid damaging rack
oil seal (inner). Install rack oil seal over sheet. Then, pull oil seal
along with OHP sheet until they pass rack assembly teeth, and
remove OHP sheet.

b. Insert rack oil seal (inner) into rack assembly piston (rack Teflon
ring).
c. Push retainer to adjusting screw side by hand, and move the
rack assembly inside the gear housing assembly so that the
rack oil seal (inner) can be pressed against the gear housing
assembly.
d. Wrap an OHP sheet [approximately 70 mm (2.76 in)´100 mm
(3.94 in)]. Around the edge to avoid damaging rack oil seal
(outer). Install rack oil seal over sheet. Then, pull oil seal along
with OHP sheet until they pass rack edge, and remove OHP
sheet.
e. Install end cover assembly to rack edge, and move rack oil seal
(outer) until it contacts with gear housing assembly.
5. Tighten end cover assembly to specified torque using a 45 mm
(1.77 in) open head (suitable tool).
CAUTION:
Do not damage rack assembly. Replace it if damaged
because it may cause fluid leakage.
6. Crimp gear housing assembly at one point using a punch as
shown in the figure so as to prevent end cover assembly from
getting loose after tightening end cover assembly.
7. Install pinion assembly to gear housing assembly.
CAUTION:
In order to protect rack oil seal from any damage, insert pin-
ion assembly out straightly.
8. Apply recommended fluid to O-ring A. Install O-ring A to rear
cover.
9. Using a rear cover wrench [SST: KV489Q0030] (A), install rear
cover to gear housing assembly.

On-Vehicle Inspection and ServiceEGS001LL
CHECKING RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal before starting the following procedure.
1. Connect the hydraulic pressure gauge [SST] between oil pump
discharge connector and high-pressure hose. Bleed air from the
hydraulic circuit while opening valve fully. Refer toPS-6, "
Air
Bleeding Hydraulic System".
2. Start engine. Run engine until oil temperature reaches 50 to
80°C(122to176°F).
CAUTION:
lLeave the valve of the hydraulic pressure gauge [SST]
fully open while starting and running engine. If engine is
started with the valve closed, the hydraulic pressure in
oil pump goes up to the relief pressure along with
unusual increase of oil temperature.
lBe sure to keep hose clear or belts and other parts when
engineisstarted.
3. Fully close the hydraulic pressure gauge [SST] valve with
engine at idle and measure the relief oil pressure.
CAUTION:
Never keep valve closed for 10 seconds or longer.
4. Open the valve slowly after measuring. Repair oil pump is the
relief oil pressure is outside the standard. Refer toPS-26, "
Dis-
assembly and Assembly".
5. After inspection, disconnect the hydraulic pressure gauge [SST] from hydraulic circuit, then add fluid and
bleed air. Refer toPS-6, "
Air Bleeding Hydraulic System".
Removal and InstallationEGS001LM
REMOVAL
1. Drain power steering fluid from reservoir tank.
2. Remove radiator shroud. Refer toCO-11, "
Components".
3. Loosen drive belt. Refer toEM-12, "
DRIVE BELTS".
4. Remove drive belt from oil pump pulley.
5. Disconnect the pressure sensor electrical connector.
6. Remove piping of high pressure and low pressure (drain fluid from their pipings). Refer toPS-30,
"HYDRAULIC LINE".
7. Remove oil pump mounting bolts, and then remove power steering pump. Refer toPS-30, "
HYDRAULIC
LINE". Relief oil pressure:
8,500 - 9,300 kpa (86.7 - 94.9 kg/cm
2, 1,233 - 1,349 psi)

ASSEMBLY
NOTE:
Secureoilpumpinaviseifnecessary.
CAUTION:
Use copper plates when securing in a vise.
1. Apply recommended grease to oil seal lips (1). Apply recom-
mended fluid to around oil seal, and then install oil seal to body
assembly.
2. Apply recommended fluid to drive shaft, and press drive shaft
into body assembly, then install snap ring.
3. Apply recommended fluid to O-ring B, and install O-ring B into
body assembly.
4. Install side plate to body assembly.
5. Install dowel pin (3) into dowel pin hole (A), and install cam ring
(2) pointing it's D
1side toward the body assembly (1) side as
showninthefigure.
lWhen installing cam ring, turn carved face with a letter E (B)
of it to rear cover.
CAUTION:
Do not confuse the assembling direction of cam ring. If
cam ring is installed facing the incorrect direction, it may
cause oil pump operation malfunction.
