INSPECTION
1. INSPECT A.D.D. ACTUATOR
(a) Disconnect the actuator connector.
(b) Measure the resistance between terminals 2 and 6.
Standard resistance: 0.3 ± 100 W
(c) Measure the resistance between terminal 2 or 6 and body
ground.
Standard resistance: More than 0.5 MW
If the resistance value is not as specified, replace the actuator
assembly.
2. INSPECT A.D.D. ACTUATOR OPERATION
Apply battery positive voltage between terminals 2 and 6, and
check the actuator operation by sound, A.D.D. status and conti-
nuity between terminals 3 and 4.

If the operation is not as specified, replace the actuator assem-
bly.
3. INSPECT LIMIT SWITCH CONTINUITY
(a) Connect the actuator connector.
(b) Push the 2WD/4HI switch and check that the 4WD indica-
tor light comes on after it is blinking.
(c) Check the A.D.D. actuator operation by sound.
(d) Disconnect the actuator connector.
(e) Check the continuity between each terminal, as shown in
the chart.

5. REMOVE A.D.D. ACTUATOR (See page SA±43)
6. INSPECT CLUTCH HUB AND CLUTCH SLEEVE
(a) Check the clutch hub and clutch sleeve for wear and dam-
age.
If necessary, replace them.
(b) Check that clutch sleeve slides smoothly on the clutch
hub.
7. MEASURE SLEEVE FORK AND CLUTCH SLEEVE
CLEARANCE
Using a feeler gauge, measure the clearance between the
sleeve fork and clutch sleeve.
Maximum clearance: 0.35 mm (0.0138 in.)
If the clearance exceeds the maximum, replace the fork or
sleeve.

the coil spring.

Do not compress the coil spring more than neces-
sary.

Do not place yourself over the top of the shock ab-
sorber.
