Note: Normal belt deflection when pressing the longest belt section with your thumb is 2 mm for a new belt and 5 mm for a used belt.
Loosen the generator bracket and tension bar bolts so that the generator rotates under its own weight (Fig. 8-5).
On a generator with a toothed tension bar, adjust the belt tension by turning the tension bar bolt with a torque wrench to 8 N·m for a new belt and 4 N·m for a used belt. On a generator with a smooth tension bar, adjust the belt tension with a lever inserted between the engine block and the generator. Tighten the generator mounting bolts and check the belt tension again.
