>> B << Balancer Timing Belt Tension Adjustment

When measuring the belt deflection:

1. With your fingers, lift the balancer timing belt tensioner in the direction of the arrow. Apply pressure of [3.0 +/- 0.4 N.m (26 +/- 4 in-lb)] to the balancer timing belt.

   Tighten the assembling bolt to the standard torque. Then, fix the balancer timing belt tensioner.

   1. Tightening torque: 19 +/- 3 N.m (14 +/- 2 ft-lb)

2. Turn the crankshaft clockwise two turns to set No.1 cylinder to TDC of its compression stroke and check that the sprocket timing marks are aligned.
3. Apply a pressure of approximately 100N (22 pounds) at the center (arrow area) between the sprocket as shown, then inspect whether the belt deflection is within the standard value.
   1. Standard value: 
   2. At adjustment: 5 - 7 mm (0.20 - 0.27 inch) 
   3. At replacement: 5 - 7 mm (0.20 - 0.27 inch)

4. If not within the standard value, adjust the belt tension again.

When using scan tool MB991502: 

1. Lift with your fingers the balancer timing belt tensioner in the direction of the arrow. Apply a tensile torque of [3.0 +/- 0.4 N.m (26 +/- 4 in-lb)] to the balancer timing belt so the belt is tense without any looseness.

   Tighten the assembling bolt to the standard torque in this state. Then, fix the balancer timing belt tensioner.

   1. Tightening torque: 19 +/- 3 N.m (14 +/- 2 ft-lb)

2. Connect special tool MB991668 to scan tool MB991502.
3. Connect special tool MB991704 to scan tool MB991502.
4. Connect special tool MB991704 to battery.

5. Turn the crankshaft clockwise two turns to set No. 1 cylinder to TDC of its compression stroke and check that the sprocket timing marks are aligned.
6. Select "BELT TENSION" on the menu screen of scan tool MB991502.
7. Hold special tool MB991668 to the middle of the drive belt between the sprockets (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).
   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.
8. Gently tap the middle of the belt between the sprockets (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.
   1. Standard value: 
   2. At adjustment: 76 - 92 Hz 
   3. At replacement: 76 - 92 Hz
