Tensioning the timing belt.
Turn the tensioner roller (8)in the direction of the arrow «c», by means of a hexagonal spanner at «d».
IMPERATVE: The index «a» should go past the slot «g» by an angular value of 10°.
If it does not, replace the tensioner roller or the timing belt and tensioner roller assembly.
Next bring the index «a» to its adjusting position «g», by turning the tensioner roller in the direction of
the arrow «e».
WARNING: the index «a» should not pass the slot «g».
Otherwise, repeat the operation to tension the timing belt.
IMPERATIVE: The tensioner roller should not turn during the tightening of its fixing.
If it does, repeat the operation to tension the timing belt.
Tighten the screw (9)of the tensioner roller (8)to 2,1 ± 0,2 m.daN.
IMPERATIVE: The hexagonal tensioner roller drive should be approx. 15° below the level of the cylinder
head gasket «h».
