a. Best tension check using belt tension gauge:
1) Set the special tool at the center between the alternator belt
pulleys, and measure the belt tension.
TOOL:
Belt tension gauge
07JGG-0010101
2) If the belt tension is out of the specification, adjust the belt
tension.
b. Belt deflection inspection
1) Measure the belt deflection by pushing the alternator belt
at the center between the pulleys with 98 N (10 kgf, 22 lbf)
of force.
Used belt
329 – 490 N
Belt tension
(40 – 50 kgf, 88 – 110 lbf)
New belt
490 – 588 N
(50 – 60 kgf, 110 – 132 lbf)
Used belt
10.6 – 11.1 mm
Belt deflection
(0.42 – 0.44 in)
New belt
10.1 – 10.6 mm
(0.40 – 0.42 in)
2) If the belt deflection is out of the specification, adjust the
belt tension.
Belt Tension Adjustment:
1) If the belt tension or belt deflection is out of the
specification, loosen the 10 x 80 mm flange bolt and the 8
mm flange nut, and adjust the belt tension or deflection by
turning the special adjusting bolt right or left.
2) After adjustment, tighten the 8 mm flange nut and the 10 x
80 mm flange bolt in this order to the specified torque.
TORQUE:
8 mm flange nut: 26 N.m (2.7 kgf.m, 20 lbf.ft)
10 x 80 mm flange bolt: 44 N.m (4.5 kgf.m, 33 lbf.ft)
3) After tightening the bolt and nut to the specified torque,
check the alternator belt tension and deflection again.
If the measurement is still out of the specification, repeat
the step 1 and 2.
Replacement:
1) Loosen the 10 x 80 mm flange bolt and the 8 mm flange
nut.
2) Loosen the special adjusting bolt and move the alternator
assembly fully to the engine side.
