INSPECTION
NOTICE:
When using a vise, do not overtighten it.
1.
CHECK OIL CLEARANCE BETWEEN VANE PUMP
SHAFT AND BUSHING
Using a micrometer and 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 shaft and front hous-
ing.
2.
INSPECT VANE PUMP ROTOR AND VANE PLATES
(a)
Using a micrometer, measure the height, thickness and
length of the 10 plates.
Minimum height: 8.6 mm (0.339 in.)
Minimum thickness: 1.40 mm (0.0551 in.)
Minimum length: 14.99 mm (0.5902 in.)
(b)
Using a feeler gauge, measure the clearance between
the rotor groove and plate.
Maximum clearance: 0.033 mm (0.0013 in.)

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
holes.
If necessary, replace the valve with one having the same letter
as inscribed on the front housing.
