CARE AND MAINTENANCE
7. V belt
7.1 Right hand V belt
Operation_Pic_number:1
The poly-V-belt (A) has an automatic belt
tensioner.
● Check for cracks, oil fouling, signs of over-
heating and wear.
● Replace damaged belts.
The tension pulley must be replaced every time
the V ribbed belt needs to be replaced.
Air conditioning compressor V-belts (see CARE
AND MAINTENANCE Section 17.2).
DANGER:
Check the V-belt tensioner only with
the engine stopped! Mount the
protective grille again.

Setting V-belt belt tightener
Operation_Pic_number:1
● Setting as delivered of distance between cen-
tres A = 92 mm.
● Re-adjustment with max. distance
A = 100 mm to A = 92 mm.
● If the distance reaches A = 100 mm again,
then replace power belt.
NOTE:
A gap between lugs (dimension A) of more
than 100 mm can lead to total failure of the
belt drive due to insufficient belt tension.
7.2 Left V-belt
Operation_Pic_number:1
V-belt tension is to be measured at the centre
point between pulleys, using Optibelt tension
gauge I.
● Loosen alternator nut (A).
● Adjustment with clamping screw (B).
Strand pull (operating tension)
450+50 N (45+5 kp).
