DISASSEMBLY
NOTICE:
When using a vise, do not overtighten it.
1. MEASURE PS VANE PUMP ROTATING TORQUE
(a) Check that the pump rotates smoothly without abnormal
noise.
(b) Temporarily install the vane pump pulley set nut.
(c) Using a torque wrench, check the pump rotating torque.
Rotating torque:
0.3 N·m (2.8 kgf·cm, 2.4 in.·lbf) or less
2. REMOVE SUCTION PORT UNION
(a) Remove the bolt and suction port union.
(b) Remove the O–ring from the union.
3. REMOVE PRESSURE PORT UNION
(a) Remove the pressure port union.
(b) Remove the O–ring from the union.
4. REMOVE FLOW CONTROL VALVE AND SPRING
5. REMOVE REAR HOUSING, WAVE WASHER AND SIDE
REAR PLATE
(a) Using 2 screwdrivers, remove the snap ring.
(b) To prevent oil seal lip damage, wind vinyl tape on the ser-
rated part of the vane pump shaft.
(c) Using a plastic hammer, tap out the rear housing, wave
washer and side rear plate.
(d) Remove the O–ring from the rear housing.
(e) Remove the O–ring from the side rear plate.
6. REMOVE CAM RING AND 10 VANE PLATES
NOTICE:
Be careful not to drop the plate.
7. REMOVE VANE PUMP SHAFT WITH VANE PUMP RO-
TOR AND SIDE FRONT PLATE
8. REMOVE VANE PUMP ROTOR AND SIDE FRONT
PLATE
(a) Using a screwdriver, remove the snap ring from the vane
pump shaft.
(b) Remove the vane pump rotor and side front plate.
(c) Remove the 2 O–rings from the side front plate.
9. REMOVE SHORTER STRAIGHT PIN

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.
