A

Indicator mark

1. Make sure that the indicator mark is within the

area marked with A in the illustration.

2. If the mark is out of the area, replace the drive

belt. (Refer to

P.11A-15

).

NOTE: The drive belt tension check is not neces-
sary as auto-tensioner is adopted.

AUTO-TENSIONER CHECK

M1111003000284

OPERATION CHECK

1. Turn OFF the engine from the idle state then

check to see that the drive belt is not protruding
from the pulley width of the auto-tensioner.

2. Remove the drive belt.(Refer to

P.11A-15

).

3. Securely insert the spindle handle or ratchet

handle with a 12.7 mm insertion angle into the jig
hole of the auto tensioner. Turn the auto-tensioner
to the left and right to check and see that there is
no threading.

4. If there are any problems in the procedure 1 or 3,

replace the auto-tensioner.(Refer to

P.11A-36

).

5. Install the drive belt.(Refer to

P.11A-15

).

FUNCTION CHECK

You can verify if the auto-tensioner is defective or not
by checking the drive belt tension.

When using the M.U.T.-II

1. Check the drive belt tension. (Refer to

P.11A-7

).

2. Measure the drive belt tension vibration frequency

by the following procedures:

CAUTION

• The temperature of the surface of the belt

should be as close to normal temperature as
possible.

• Do not allow any contaminants such as water

or oil to get onto the microphone.

• If strong gusts of wind blow against the

microphone or if there are any loud sources
of noise nearby, the values measured by the
microphone may not correspond to actual
values.

• If the microphone is touching the belt while

the measurement is being made, the values
measured by the microphone may not corre-
spond to actual values.

• Do not take the measurement while the vehi-

cle's engine is running.

(4) Hold special tool belt tension meter set

(MB991668) to the middle of the drive belt
between the pulleys (at the place indicated by
arrow), approximately 10

− 20 mm away from

the rear surface of the belt so that it is
perpendicular to the belt (within an angle of

±

15 degree).

(5) Gently tap the middle of the belt between the

pulleys (the place indicated by the arrow) with
your finger as shown in the illustration, and
measure that the vibration frequency of the
belt is within the standard value.

Standard value: 110

− 144 Hz

3. If not within the standard value, replace the

auto-tensioner. (Refer to

P.11A-36

).

When using the V.C.I.

1. Check the drive belt tension. (Refer to

P.11A-7
