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 correspond to actual values.
- Do not take the measurement while the vehicle's engine is running.
- Hold special tool MB991668 to the middle of the drive belt between the pulleys (at the place indicated by arrow), approximately 10-20 mm (0.40 - 0.78 inch) away from the rear surface of the belt so that it is perpendicular to the belt (within an angle of +/- 15 degree).
- 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
- If not within the standard value, replace the auto-tensioner. (Refer to CRANKSHAFT PULLEY .)
