Slacken the nut while maintaining the position of the tensioner roller, with the aid of a hexagonal
spanner at «a».
Next bring the index «c»to its adjusting position «e».
WARNING: The index «c» must not go beyond the notch «e». If it should do this, restart the
timing belt tensioning operation.
Hold the tensioner roller in this position with the aid of a hexagonal spanner.
Tighten the tensioner roller fixing nut to 2.2 ± 0.2 m.daN.
IMPERATIVE: The tensioner roller must not rotate during the tightening of its fixing. If it
does, restart the timing belt tensioning operation.
