Measurement of Deflection Amount and Vibration
Frequency
1. Press the middle of the belt with a force of 98 N (approx.
10 kgf, 22 lbf), and check whether the amount of
deflection is within the following range.
Fan belt deflection value: 6~8 mm (0.2~0.3 in)
2. When the value is not within the range, adjust the
tension.
3. Check the belt for a damage such as a scratch and crack.
4. When the belt adjusting allowance is no longer available,
when crack, damage or abnormal wear is found, or
when the belt squeaks during driving even after the belt
tension has been adjusted, replace the belt.
Adjusting Drive Belt
1. Loosen idler pulley's lock nut (1).
Lock nut (1): 137~157 N·m (14~16 kgf·m, 101~116 lbfft)
2. Turn the generator and idler pulley adjusting bolts (2, 3)
to adjust the belt tension to be within the standard value
range.
3. After the adjustment, firmly tighten loosened lock nut (1)
to the specified torque.
