8.7 TENSIONING AND REPLACING THE BELTS
Lavina® V20GE has two belts. Changing or tensioning them happens by the following steps:
-
Unscrew the seven bolts that are holding the rear protective cover of the vacuum (fig. 8.7
pos. 1);
-
Remove the protective cover (fig 8.7 pos. 2);
-
Loosen the four bolts that are holding the engine base plate (fig. 8.7 pos. 3);
-
By screwing or unscrewing the tensioning bolt (fig. 8.7 pos. 4) the belts are being tensioned
or loosened depends on your needs. By loosening the belts you can remove them and
change them.
For tensioning the belts make sure you are using OPTIKRIK 1 fig. 8.7.1. If the belt is new it
must be tensioned to 309N, and if it’s used - 237N. After the tensioning is accomplished the four
bolts fig. 8.7 pos. 3 must be screwed back to fix the engine’s current position.
