2. Press the belt with a force of 98 N (10 kgf) exactly in the middle between the alternator pulley and the engine crankshaft pulley.
Helpful advice. If it is difficult to assess the force generated by the hand, you can use a household steelyard with a maximum allowable load of 10 kg, as this is done when checking the timing belt.
A properly adjusted alternator belt should bend 6-8 mm. If the deflection of the belt is not correct, then adjust the belt tension. For this:
3. With a 13 mm socket or socket wrench, we loosen the tightening of the nut of the bolt of the lower mounting of the generator.
4. With a 13 mm spanner, we loosen the tightening of the nut of the tension bar of the generator.
5. Turning the adjusting bolt with a ring wrench by 10 mm, we adjust the belt tension (clockwise - increase the alternator belt tension, and counterclockwise - decrease).
Warning. Excessive belt tension can lead to failure of the alternator front bearing.
6. We check the tension of the regulator belt and, if necessary, repeat the adjustment.
7. After making sure that the alternator belt is tensioned correctly, tighten the tension bar nut with a 13 mm spanner wrench.
8. Using a 13 mm socket wrench, tighten the nut of the lower mounting bolt of the generator.
