Due to higher alternator output, present V-belt tension is insufficient.
Adjust belt tension as follows:
- loosen bolts 1 and 2 and pivot alternator

Alternator V-belts up to 1000 mm long (39.4 in)
2 mm max. (0.079 in) deflection with new belt, thumb pressure
5 mm max. (0.197 in) deflection with previously run belt, thumb pressure

Alternator V-belts over 1000 mm long (39.4 in)

10 mm max. (0.394 in) deflection with new belt, thumb pressure
15 mm max. (0.59 in) deflection with previously run belt, thumb pressure

Note: Extremely loud squealing may indicate damaged V-belt that should be replaced
