Checking
If you push the belt at the center between the alternator (1) and
the drive pulley (2) with your thumb
[approximately 98.1N (10 kgf)] and you get deflection of (A), it is
normal.
(A): 13 to 16 mm (0.51 to 0.63 in)
Adjustment

alternator.

Adjust the belt tension with nut (9) as follows:
TIGHTEN to INCREASE tension
LOOSEN to DECREASE tension
2. After adjusting the belt, tighten the bolts and nuts (3) to (8) in
the order of (8) to (3) (the opposite order from loosening).
Finally, tighten nut (9).

Check each pulley for damage, wear of the V-groove, and
wear of the V-belt. Check in particular that the V-belt does
not contact the bottom of the V-groove.

If the V-belt is elongated and there is no more allowance
for adjustment, or if the belt is cracked or cut, replace the
belt.

When the V-belt has been replaced, adjust again after
running for 1 hour.
