(b) Check the valve seating position.
Apply a light coat of prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do not
rotate valve.
(c) Check the valve face and seat for the following:
If blue appears 360° around the face, the valve is
concentric. If not, replace the valve.
If blue appears 360° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
Check that the seat contact is in the middle of the
valve face with the following width:
1.0 - 1.4 mm (0.039 - 0.055 in.)
If not, correct the valve seats as follows:
If the seating is too high on the valve face, use 30°
and 45° cutters to correct the seat.
If the seating is too low on the valve face, use 60°
and 45° cutters to correct the seat.
(d) Hand-lap the valve and valve seat with an abrasive com-
pound.
(e) After hand-lapping, clean the valve and valve seat.
12. INSPECT VALVE SPRINGS
(a) Using a steel square, measure the deviation of the valve
spring.

2. FOR VEHICLE EQUIPPED WITH VEHICLE SKID CON-
TROL (VSC) SYSTEM
(a) Precaution when using drum tester:
When using a drum tester, make sure that the ignition
switch is OFF, start the engine with the diagnosis connec-
tor short-circuited between Ts and E
1 (CG) and take a
measurement.
NOTICE:
Check that VSC warning light is blinking.
Ensure that the vehicle does not move using wires.
After the measurement, disconnect the short circuit
and check that the VSC warning light is turned off
when restarting the engine.
(b) Precaution during VSC operation:
(1) Since VSC may be affected by the removal/installa-
tion of the VSC-related parts, do not remove/install
those parts unless absolutely necessary.
(2) When operating on VSC, follow the instructions in
BR section in this manual to surely make prepara-
tions or check after operations.
3. WHEN SERVICING FULL-TIME 4WD VEHICLES
The Full-time 4WD LAND CRUISER is equipped with the me-
chanical lock type center differential system.
During tests using a brake tester or chassis dynamometer, such
as braking force tests or speedometer tests, if only the front or
rear wheels are to be rotated, it is necessary to set the position
of the center differential to FREE or LOCK depending on the
type of the test being performed.

(b) Using Braking Tester:
Measure by low-speed type (Vehicle Speed: Below 0.5
km/h or 0.3 mph) brake tester and observe the following
instructions before performing the test.
(1) Position the wheels to be tested (front or rear) on
the tester.
(2) Put the center differential in FREE position.
(3) If the vehicle is equipped with Vehicle Skid Control
(VSC) system, prohibit the system from the activa-
tion (See step 2.).
(4) Shift the transmission shift lever to ºNº position.
HINT:
Do not forget to change the Vehicle Skid Control (VSC) & Trac-
tion Control (TRAC) system to operational condition after the
test. Check that the VSC warning indicator light goes off when
restarting the engine.
(c) Using Speedometer Tester:
Observe the following instructions and then measure with
the rear wheels.
(1) Position the rear wheels on the tester roller.
(2) Position the front wheels on the free roller or jack
them up.
(3) Put the center differential in FREE position.
(4) If the vehicle is equipped with Vehicle Skid Control
(VSC) & Traction Control (TRAC) system, prohibit
the system from the activation (See step 2.).
(5) Ensure that the vehicle does not move using wires.
CAUTION:
The maximum speed should be less than 60 km/h (37 mph)
and maximum driving time should be 1 minute.
HINT:
Sudden shifting, braking, acceleration or deceleration is
not allowed.
Do not forget to change the Vehicle Skid Control (VSC) &
Traction Control (TRAC) system to operational condition
after the test. Check that the VSC warning indicator light
goes off when restarting the engine.
