10. REMOVE VANE PUMP HOUSING OIL SEAL
(a) Using a screwdriver and a shop rag or a piece of
cloth, remove the vane pump housing oil seal from
the vane pump front housing.
NOTICE:
Be careful not to damage the vane pump front
housing.
INSPECTION
1. INSPECT VANE PUMP SHAFT AND BUSHING IN
VANE PUMP FRONT HOUSING
(a) Using a micrometer, measure the outer diameter [a]
of the vane pump shaft with pulley.
(b) Using vernier calipers, measure the inner diameter
[b] of the vane pump front housing bushing.
(c) Calculate the oil clearance.
Oil clearance = Inner diameter of the bushing [b] -
Outer diameter of the shaft [a]
Maximum oil clearance:
0.07 mm (0.0028 in.)
If the oil clearance exceeds the maximum, replace
the vane pump assembly.
2. INSPECT VANE PUMP ROTOR AND VANE PUMP
PLATE CLEARANCE
(a) Using a micrometer, measure the thickness of the
vane pump plates.
Standard thickness:
1.405 to 1.411 mm (0.05531 to 0.05555 in.)
If the thickness is not within the specified range,
replace the vane pump assembly.
(b) Using a feeler gauge, measure the clearance
between the side face of the vane pump rotor
groove and the vane pump plates.
Maximum clearance:
0.03 mm (0.0012 in.)
If the clearance exceeds the maximum, replace the
vane pump assembly.

3. INSPECT FLOW CONTROL VALVE ASSEMBLY
(a) Coat the flow control valve assembly with power
steering fluid and check that it falls smoothly into the
flow control valve due to its own weight.
If the control valve does not fall into the hole
smoothly, replace the vane pump assembly.
(b) Check the flow control valve assembly for leaks.
Close one of the holes and apply compressed air,
392 to 490 kPa (4 to 5 kgf/cm
2, 57 to 71 psi), into
the opposite side hole, and confirm that air does not
come out from the holes in the ends of the flow
control valve assembly.
If air leaks, replace the vane pump assembly.
4. INSPECT FLOW CONTROL VALVE COMPRESSION
SPRING
(a) Using vernier calipers, measure the free length of
the flow control valve compression spring.
Minimum free length:
29.2 mm (1.150 in.)
If the length is less than the minimum, replace the
vane pump assembly.
5. INSPECT PRESSURE PORT UNION
If the union seat in the pressure port union is severely
damaged, replace the vane pump assembly.
6. INSPECT TOTAL PRELOAD
(a) Check that the pump rotates smoothly without
abnormal noise.
(b) Temporarily install the service bolt.
Recommended service bolt:
Thread diameter:
10 mm (0.39 in.)
Thread pitch:
1.25 mm (0.0492 in.)
Bolt length:
50 mm (1.97 in.)
(c) Using a torque wrench, check the pump rotating
torque.
Rotating torque:
0.27 N*m (2.8 kgf*cm, 2.4 in.*lbf) or less
If the rotating torque is not as specified, check the
vane pump housing oil seal.
