INSPECTION
NOTICE:
When using a vise, do not overtighten it.
1. MEASURE OIL CLEARANCE BETWEEN VANE PUMP
SHAFT AND BUSHING
Using a micrometer and caliper gauge, measure the oil clear-
ance.
Standard clearance:
0.01 – 0.03 mm (0.0004 – 0.0012 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 (0.0708 in.)
Minimum length: 14.988 mm (0.5901 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 the 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 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 hole, and con-
firm that air does not come out from the end hole.
If necessary, replace the valve with the one having the same let-
ter as inscribed on the front housing.

4. INSPECT SPRING
Using vernier calipers, measure the free length of the spring.
Minimum free length: 36.0 mm (1.417 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 front housing.
(b) Coat a new oil seal lip with power steering fluid.
(c) Using SST and a press, press in the oil seal.
