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 compressed air 392 −
490 kPa (4 − 5 kgf/cm
2, 57 − 71 psi) into the opposite side,
and confirm that air does not come out from the end hole.
If necessary, replace the valve with one having the same letter
on the front housing.
Inscribed mark: A, B, C, D, E or F
4. INSPECT SPRING
Using calipers, measure the free length of the spring.
Minimum free length: 32.3 mm(1.272 in.)
If it is not within the specification, replace the spring.
5. IF NECESSARY, REPLACE OIL SEAL
(a) Using SST, tap out the oil seal from the front housing.
SST 09631−10030
NOTICE:
Be careful not to damage the bushing of the front housing.
(b) Coat a new oil seal lip with power steering fluid.

NOTICE:
Make sure to install the oil seal facing the correct direction.
6. IF NECESSARY, REPLACE BEARING
(a) Press out the bearing from the vane pump shaft.
(b) Using a snap ring expander, remove the snap ring from
the shaft.
NOTICE:
Be careful not to damage the shaft.
(c) Using a snap ring expander, install a new snap ring to the
shaft.
