Check alternator belt tension, adjust
Checking
The standard deflection for the drive belt is about 15 mm (0.6 in)
when pressed by thumb 58.8 N (about 6 kgf, 43.4lb) at a point
midway between the drive pulley and alternator pulley.
Adjusting
1. Loosen bolts (1), (2) and nut (3).
1. Turn nut (4) to the right to move alternator (5) and adjust so
that the deflection of the belt is approx. 15 mm (0.6 in)
{approx. 58.8 N {6 kgf)}.
Tighten nut (4) to increase the tension of the belt; loosen nut
(4) to reduce the tension of the belt.
2. Tighten bolts (1), (2) and nut (3) to secure alternator (5).
3. Check each pulley for damage, wear of the V-groove, and
wear of the V-belt. Be particularly careful to check that the V-
belt is not in contact with the bottom of the V-groove.
4. If the belt has elongated and there is no more allowance for
adjustment, or if the belt is cut or cracked, replace the belt.
5. After replacing the belt, operate for one hour, then adjust
again.
