Belt tension meter set (MB992080)

1. Connect the Special tool microphone assembly 

(MB992082) to the Special tool belt tension meter 
(MB992081) of the Special tool belt tension meter 
set (MB992080).

2. Press the "POWER" button to turn on the power 

supply.

3. Press number key 1. Check to ensure that "No. 

01" appears on the upper left of the display and 
that the following numeric values are displayed for 
individual items (M, W, and S):
M 000.9 g/m
W 010.0 mm/R
S 0100 mm
If numeric values have not been entered (new 
tool), set them according to the belt specifications 
as shown below. Once you set them, you do not 
have to set them again. The settings remain 
undeleted even after battery replacement.
NOTE: This operation is to temporarily set the 
preset data such as the belt specifications, 
because if the measurement is taken without input 
of the belt specifications, conversion to tension 
value (N) cannot be made, resulting in judgement 
of error.
<Setting procedure>
(1) Press down the "MASS" button till the belt 

mass select display appears.

(2) Press the "UP" or "DOWN" button to select "01 

1.5GT 0.9" and press the "MEASURE" button 
to decide it.
Check to ensure that "M 000.9 g/m" is 
displayed.

(3) Press the "WIDTH" button to change to the 

belt width input display.

(4) Press number keys 0, 1, 0, and 0 sequentially, 

and press the "SELECT" button to apply them. 
Check to ensure that "W 010.0 mm/R" 
appears on the display.

(5) Press the "SPAN" button to change to the 

span length input display.

(6) Press number keys 0, 1, 0, and 0 sequentially, 

and press the "SELECT" button to apply them. 
Check to ensure that "S 0100 mm" appears on 
the display.

4. Press "Hz" button twice to change the display to 

the frequency display (Hz).

(Microphone)

The temperature of the surface of the belt should 

be as close as possible to normal tempera-
ture.

• Do not let any contaminants such as water or 

oil get onto the microphone.

• If strong gusts of wind blow against the 

microphone or if there is 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.

5. Hold the microphone to the middle of the drive 

belt between the pulleys (at the place indicated by 
the arrow), about 10 

− 15 mm away from the rear 

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

± 15 °).

6. Press the "MEASURE" button.
7. 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 check 
that the vibration frequency of the belt is within the 
standard value.
NOTE: To take the measurement repeatedly, fillip 
the belt again.

8. After the completion of the measurement, press 

and hold the "POWER" button to turn off the 
power supply.

<When the vibration frequency is 
measured vehicle communication 
interface (V.C.I.) is used: 
Recommendation>

NOTE: The vibration frequency measuring method is 
recommended for check and adjustment of the drive 
belt tension.

1. Connect the special tool belt tension meter set 

(MB991668) to the special tool V.C.I (MB991824).

2. Connect special tool M.U.T.-III main harness A 

(MB991910) to special tool V.C.I. (MB991824).

3. Connect special tool M.U.T.-III main harness A 

(MB991910) to the diagnosis connector.

4. Turn the ignition switch to the "ON" position and 

select "Belt Tension Measurement" from the menu 
screen.

1. Loosen the nut of the nut for alternator pivot bolt.
2. Loosen the alternator fixing nut.
3. Use the adjusting bolt to adjust the belt tension 

and belt deflection to the standard values.

4. Tighten the nut of the nut for alternator pivot bolt.

Tightening torque: 47 

± 5 Nm

5. Tighten the alternator fixing nut.

CAUTION

When checking the belt tension, turn the crank-
shaft clockwise one turn or more.
7. Check the belt tension, and readjust if necessary.
8. When the belt tension is adjusted by measuring 

the deflection, adjust it with a tool for vibration 
frequency measurement or tension measurement 
afterward.
