3. INSPECT FLOW CONTROL VALVE
(a) Coat the valve with power steering fluid and check that it
falls smoothly into the valve hole by its own weight.
(b) Check the flow control valve for leakage. Close one of the
holes and apply 392 - 490 kPa (4 - 5 kgf/cm
2, 57 - 71 psi)
of compressed air into the opposite side hole, and confirm
that air does not come out from the end holes.

side rear plate.
9. INSTALL REAR HOUSING
(a) Coat a new O-ring with power steering fluid and install it
to the rear housing.
(b) Install the rear housing and use a press to push down on
the wave washer hard enough to compress it.
NOTICE:
Do not apply too much pressure.
Be careful not to damage the O-ring.
10. INSTALL SPRING, FLOW CONTROL VALVE AND
PRESSURE PORT UNION

INSPECTION
NOTICE:
When using a vise, do not overtighten it.
1. INSPECT STEERING RACK
Using a dial indicator, check the rack for runout and teeth wear
and damage.
Maximum runout: 0.30 mm (0.0118 in.)
2. MEASURE OIL CLEARANCE BETWEEN CONTROL
VALVE ASSEMBLY AND BUSHING
Using a micrometer and a cylinder gauge, measure the oil clear-
ance.
Standard clearance:
0.050 - 0.083 mm (0.00197 - 0.00327 in.)
Maximum clearance: 0.125 mm (0.00492 in.)
3. IF NECESSARY, REPLACE BUSHING AND OIL SEAL
(a) Using SST and 2 steel plates, remove the bushing from
the rack housing.
SST 09612-65014 (09612-01030)
NOTICE:
As shown, from the opposite side of SST confirm that
its claw is firmly caught on the bushing.
Be careful not to damage the rack housing.
(b) Using a brass bar and a hammer, remove the oil seal from
the rack housing.
NOTICE:
Be careful not to damage the rack housing.
(c) Coat a new oil seal lip with power steering fluid.
(d) Using a socket wrench (24 mm), extension bar and ham-
mer, press in the oil seal.
NOTICE:
Make sure to install the oil seal facing the correct direction.

(e) Using a socket wrench (24 mm) and a extension bar, care-
fully press in a new bushing to a depth of 73 mm (2.87 in.).
NOTICE:
If the bushing is pushed in too far, it will cause deformation
of the rack housing. If it is not pushed in far enough, it will
interfere with the control valve assembly. Therefore, al-
ways use a press and install the bushing to the proper
depth. Then, install the control valve assembly and ensure
that it rotates smoothly.
4. IF NECESSARY, REPLACE TEFLON RING AND
O-RING
(a) Using a screwdriver, remove the teflon ring and O-ring
from the steering rack.
NOTICE:
Be careful not to damage the groove for the teflon ring.
(b) Coat a new O-ring with power steering fluid and install it.
(c) Expand a new teflon ring with your fingers.
NOTICE:
Be careful not to overexpand the ring.
(d) Coat the ring with power steering fluid.
(e) Install the ring to the steering rack and settle it down with
your fingers.
5. IF NECESSARY, REPLACE TEFLON RINGS
(a) Using a screwdriver, remove the 4 rings from the control
valve assembly.
NOTICE:
Be careful not to damage the grooves for the ring.
(b) Expand 4 new teflon rings with your fingers.
NOTICE:
Be careful not to overexpand the ring.
