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 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 vane plates.
Minimum height: 8.6 mm (0.339 in.)
Minimum thickness: 1.40 mm (0.0551 in.)
Mininum length: 14.99 mm (0.5902 in.)
(b) Using a feeler gauge, measure the clearance between

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 compressed air into the opposite side,
and confirm that air does not come out from the end holes.
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
