1. Proper alternator belt tension is critical to extending the life of the alternator. If the belt is too loose, the battery may be undercharged; if the belt is too tight, the alternator bearings will wear out quickly. In any case, this will adversely affect the belt itself, the service life of which will be noticeably reduced.
2. The belt tension is adjusted by turning the alternator, which must be locked in position for the correct belt tension.
3. Before adjusting the tension of the belt, check that it sits correctly on both pulleys. Make two marks on the outer surface of the loose belt 100 mm apart and lightly tighten the pivot bolts and adjusting rod bolts.
4. Turn the alternator outward so as to tension the belt. You can press the generator with a wooden lever, but it can only be supported from the side of the generator pulley, because. otherwise, you may damage the alternator housing or rear cover.
5. Tighten the belt so that the distance between the marks made increases to 101.5-102 mm (for new belt) or 101.8-102.8 mm (for the old belt).
