INSPECTION OF POWER STEERING
PUMP
1. MEASURE OIL CLEARANCE OF SHAFT AND BUSH-
ING
Using a micrometer and calipers, measure the oil clear-
ance.
Standard clearance: 0.01 = 0.03 mm
(0.0004 ± 0.0012 in.)
Maximum clearance: 0.07 mm (0.O028 in.)
If more than maximum, replace the entire power steering
pump.
2. INSPECT ROTOR AND VANE PLATES
(a) Using a micrometer, measure the height, thickness
and length of the vane plates.
Minimum height: 8.0 mm (0.315 in.)
Minimum thickness: 1.77 mm (0.0697 in.)
Minimum length: 14.97 mm (0.5894 in.)
(b) Using a feeler gauge, measure the clearance be-
tween the rotor groove and vane plate.
Maximum clearance: 0.03 mm (0.0012 in.)
If more than maximum, replace the vane 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 five vane lengths with the following ro-
tor and cam ring marks:
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 [4
±5 kg/crn
2 (57 ± 71 psi, 392 ± 490 kPa)] into the oppo-
site side, and confirm that air does not come out from
the end hole.
4. INSPECT FLOW CONTROL SPRING
Using a scale, measure the free length of the spring.
Spring length: 36 ± 38 mm (1.42 ± 1.49 in.)
If not within specification, replace the spring. If necessary, replace the valve with one having the
same letter as inscribed on the front housing.
Inscribed mark: A,6,C,6, E or F
5. IF NECESSARY, REPLACE OIL SEAL
A
(a) Using a screwdriver, pry out the oil seal.
(b) Using a socket wrench and hammer, drive in a new
oil seal.
