INSPECTION
NOTICE:
When using a vise, do not overtighten it.
1. MEASURE OIL CLEARANCE BETWEEN VANE PUMP
SHAFT AND BUSHING
Using a micrometer and a caliper gauge, measure the oil clear-
ance.
Standard clearance:
0.03 − 0.05 mm (0.0012 − 0.0020 in.)
Maximum clearance: 0.07 mm (0.0028 in.)
If it is more than the maximum, replace the front housing and
vane pump shaft.
2. INSPECT VANE PUMP ROTOR AND VANE PLATES
(a) Using a micrometer, measure the height, thickness and
length of the 10 plates.
Minimum height: 8.1 mm (0.319 in.)
Minimum thickness: 1.797 mm (0.0707 in.)
Minimum length: 14.988 mm (0.59008 in.)
(b) Using a feeler gauge, measure the clearance between
the rotor groove and plate.
Maximum clearance: 0.03 mm (0.0012 in.)
If it is more than the maximum, replace the plate and/or rotor
with one having the same mark stamped on the cam ring.
Inscribed mark: 1, 2, 3, 4 or None

3. INSPECT FLOW CONTROL VALVE
(a) Coat the flow control 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 hole.
If necessary, replace the valve with one having the same letter
as inscribed 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: 36.0 mm (1.42 in.)
If it is not within the specification, replace the spring.
5. IF NECESSARY, REPLACE OIL SEAL
(a) Using a screwdriver with vinyl tape wound around its tip,
remove the oil seal.
NOTICE:
Be careful not to damage the bushing of the front housing.
(b) Coat a new oil seal lip with power steering fluid.
(c) Using SST, press in the oil seal.
