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

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

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.

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.
