CHECKING AND SETTING THE VALVE TIMING
Engine: RFN
Tensioning the timing belt.
Refitting (continued).
Turn the tensioner roller (9)in the direction of the arrow «c», using a hexagonal spanner at «d».
Place the index «a»in position «f».
IMPERATIVE: 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 tensioner roller and timing belt assembly.
Then bring the index «a»to its adjustment position «g», by turning the tensioner roller in the direction of
the arrow «e».
WARNING: The index «a» must not go past the slot «g».
If it does, restart the operation to tension the timing belt.
IMPERATIVE: The tensioner roller must not turn during the tightening of its fixing.
If it does turn, restart the operation to tension the timing belt.
Tighten the screw (8)of the tensioner roller (9)to 2,1 ± 0,2 m.daN.
IMPERATIVE: The hexagonal tensioner roller drive should be at approx. 15° below the level of
the cylinder head gasket «h».
Otherwise, replace the tensioner roller or the tensioner roller and timing belt assembly.
