HINT:
There are 3 vane plate lengths for the following rotor and cam
ring marks.
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 valve for leakage. Close one of the holes and apply 392 − 490 kPa (4 − 5 kgf/cm
2, 57 − 71 psi) of com-
pressed air into the opposite side, and confirm that air
does not come out from the end holes.
Inscribed mark:
A, B, C, D, E or F
4. INSPECT SPRING
Using calipers, measure the free length of the spring. Minimum free length: 35 − 37 mm (1.38 − 1.46 in.)
If it is not within the specification, replace the spring.

5. IF NECESSARY, REPLACE BEARING
(a) Using 2 screwdrivers, remove the snap ring from the vane
pump shaft.
NOTICE:
To prevent vane pump shaft damage, wind tape on the
shaft.
(b) Using a press, press out the bearing.
(c) Coat a new bearing with power steering fluid.
(d) Using a press, press in the bearing.
NOTICE:
Be careful not to damage the shaft.
(e) Install a new snap ring to the shaft.
6. IF NECESSARY, REPLACE OIL SEAL
(a) Using a screwdriver and hammer, tap out the oil seal from
the front housing.
NOTICE:
Be careful not to damage the housing.
(b) Coat a new oil seal lip with power steering fluid.
(c) Using a socket wrench (23 mm), press in the oil seal as shown in the illustration.
NOTICE:
Make sure you install the oil seal facing the correct
direction.
Be careful not to damage the front housing.

STEERING WHEEL
INSPECTION
1. CHECK STEERING WHEEL FREEPLAY
(a) With the vehicle stopped and tires pointed straight ahead,
rock the steering wheel gently back and forth with light fin-
ger pressure.
(b) Freeplay should not exceed the maximum. Maximum freeplay: 40 mm (1.58 in.)
If the freeplay exceeds the maximum, adjust it in the following
procedure.
2. ADJUST STEERING GEAR
(a) Point the front wheels straight ahead.
(b) Loosen the adjusting screw lock nut.
(c) Turn the cross shaft adjusting screw clockwise to de- crease steering wheel freeplay and counterclockwise to
increase it.
HINT:
Turn the adjusting screw in small increments and check the
freeplay between each adjustment.
(d) Turn the steering wheel half way around in both direc- tions.
(e) Check that the freeplay is correct and steering is smooth and without rough spots.
(f) Torque the adjusting screw lock nut (See page SR−41).
3. CHECK STEERING EFFORT
(a) Center the steering wheel.
(b) Remove the steering wheel pad (See page SR−11).
(c) Start the engine and run it at idle.
(d) Measure the steering effort in both directions.
