INSPECTION AND REPLACEMENT
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.
   Oil clearance mm (in.)
 Standard 0.03±0.05 (0.0012±0.0020)
 Maximum 0.07 (0.0028)
2. INSPECT VANE PUMP ROTOR AND VANE PLATES
(a) Using a micrometer, measure the height, thickness and
length of the 10 vane plates.
   Minimum mm (in.) 
 Height
 
 8.6 (0.339)
 Thickness 1.40 (0.0551)
 Length 14.99 (0.5902)
(b) Using a feeler gauge, measure the clearance between the
rotor groove and plate.
   Clearance mm (in.)
 Maximum 0.035 (0.0014)
If more than maximum, replace the plate and/or rotor with one
having the same mark stamped on the cam ring.
Inscribed mark:
1, 2, 3, 4 or None
HINT: There are 5 vane lengths with the following rotor and
cam ring marks:
 
 Rotor and cam
ring number 
 Vane plate length mm (in.)
 None 14.999±15.001 (0.59051±0.59059) 1 14.997±14.999 (0.59043±0.59051)

 4 14.991±14.993 (0.59020±0.59027)
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. SR±28
± STEERINGPOWER STEERING VANE PUMP

(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 let-
ter as inscribed on the front housing.
Inscribed mark:
A, B, C, D, E or F
4. INSPECT SPRING
Using calipers, measure the free length of the spring.
