INSPECTION
INSPECT FUEL TANK AND LINE
(a) Check the fuel lines for cracks or leakage, and all connec-
tions for deformation.
(b) Check the fuel tank vapor vent system hoses and connec-
tions for looseness, sharp bends or damage.
(c) Check the fuel tank for deformation, cracks, fuel leakage
or tank band looseness.
(d) Check the filler neck for damage or fuel leakage.
(e) Hose and pipe connections are as shown in the illustra-
tion.
If a problem is found, repair or replace the parts as necessary.

3. INSPECT FIELD COIL
(a) Check the field coil for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the lead wire and field coil brush lead.
If there is no continuity, replace the field frame.
(b) Check the field coil for ground.
Using an ohmmeter, check that there is no continuity be-
tween the field coil end and field frame.
If there is continuity, repair or replace the field frame.
4. INSPECT BRUSHES
Using vernier calipers, measure the brush length.
Standard length: 15.5 mm (0.610 in.)
Minimum length: 10.0 mm (0.394 in.)
If the length is less than minimum, replace the brush holder and
field frame.
5. INSPECT BRUSH SPRINGS
Check the brush spring load.
Take the pull scale reading the instant the brush spring
separates from the brush.
Standard spring installed load:
1.2 kW13.7 ± 19.6 N (1.4 ± 2.0 kgf, 3.0 ± 4.4 lbf)
1.4 kW17.6 ± 23.5 N (1.8 ± 2.4 kgf, 3.9 ± 5.3 lbf)
Minimum spring installed load:
1.2 kW9.8 N (1.0 kgf, 2.2 lbf)

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.
5S±FE and 1MZ±FE Engines:
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 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 plates.
5S±FE and 1MZ±FE Engines:
Minimum height: 8.6 mm (0.339 in.)
Minimum thickness: 1.397 mm (0.0550 in.)
Minimum length: 14.991 mm (0.5902 In.)
(b) Using a feeler gauge, measure the clearance between
the rotor groove and plate.
5S±FE and 1MZ±FE Engines:
Maximum clearance: 0.035 mm (0.0014 in.)
If it is more than the maximum, replace the plate and/or rotor
with one having the same mark stamped on the cam ring.

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 valve for leakage. Close one of the holes and
apply 392±490 kPa (4±5 kgf/cm

pressed 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 letter
as inscribed on the front housing.
