Engine: RFJ
Checking and setting the timing (continued).
Refitting.
Turn the tensioner roller (9), using tool [5a]to go past the notch «b».
Position the tool [5b] to lock the index «a»and remove the tool [5a].
NOTE: Check the presence of the crankshaft pinion keyway (12)before positioning the timing belt.
Reposition the timing belt (8)on the crankshaft pinion (1).
Hold the timing belt in place (8)using tool [3].
Put the timing belt (8)in place, in the following sequence:
- Guide roller (11).
- Inlet camshaft pulley (7).
- Exhaust camshaft pulley (6).
- Coolant pump (13).
- Tensioner roller (9).
NOTE: Make sure that the timing belt (8)is as flush as possible with the outer faces of the various
pinions and rollers.

ENGINECHECKING AND SETTING THE VALVE TIMING
Engine: RFJ
Tensioning the timing belt.
Refitting (continued).
Turn the tensioner roller (9)anti-clockwise, using a hexagonal spanner at «c».
Place the index «a»in position «e».
IMPERATIVE: The index «a» should go past the slot «f» 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 «f», by turning the tensioner roller in the direction of
the arrow «d».
WARNING: The index «a» must not go past the slot «f».
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 (10)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 «g».
Otherwise, replace the tensioner roller or the tensioner roller and timing belt assembly.
