OPERATIONS INSIDE THE ENGINE COMPARTMENT
PERIODIC INSPECTION AND MAINTENANCE
2-11
CAUTION
•
The temperature of the surface of the belt
should be as close as possible to normal tem-
perature.
•
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 USING THE TENSION GAUGE>
Use a belt tension gauge to check that the belt ten-
sion is within the standard value.
<BELT DEFLECTION CHECK>
Apply approx. 100 N of force to the middle of the
drive belt between the pulleys (at the place indicated
by the arrow) and check that the amount of deflection
is within the standard value.
When the belt tension is adjusted by measuring the
belt deflection, adjust it with a tool for vibration fre-
quency measurement or tension measurement after-
ward.
If not within the standard value, adjust the belt ten-
sion by the following procedure.
1. Loosen the nut of the alternator pivot bolt.
2. Loosen the alternator fixing bolt.
3. Use the adjusting bolt to adjust the belt tension
and belt deflection to the standard values.
