A buzzing sound can be heard when the V-belt is touched. Read off value from the scale and multiply by 100 (10). The value corresponds to the V-belt tension in N (kp).   V-belt tension   New   450 (45) N (kp)     Run-in   250 to 300 (25 to 30) N (kp)       Adjust

If the V-belt tension does not correspond to the prescribed value, loosen the alternator from the bracket and tightener plate. Readjust V-belt tension by turning alternator outwards (= +), or inwards (= -). Fasten alternator to bracket and to tightener plate.     Tighten (Torque)    Alternator to bracket   50 Nm / 37 lbf. ft   Alternator to shackle   - 25 Nm / 18 lbf. ft
