DRIVE BELT ADJUSTMENT
INSPECTION
Check drive belts for wear or damage, and replace with
new ones as necessary. Check belts for tension, and
adjust as necessary.
1) Check drive belt tension.
2) Push the middle of belt with a force of 98 N
(10 kg/22 lb) and check each belt for deflection.
Standard deflection:
For A.C. generator & fan pulley drive belt
Initial tension : 8 – 12 mm (0.31 – 0.47 in)
Tension at readjustment : Same as above.
For A/C compressor drive belt
Initial tension : 7 – 10 mm (0.28 – 0.38 in)
Tension at readjustment : 5 – 8 mm (0.20 – 0.31 in)
TENSION ADJUSTMENT
1) Loosen AC generator mounting bolt to move AC
generator, adjust belt tension and tighten to the
specified torque.
