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.

-Tensioner roller (8).
NOTE:Make so that the belt (7)is as flush as possible with the exterior face of the various
pinions and rollers.
Remove:
- Tool [3].
- Tool [1]from the exhaust camshaft pulley.
- Tool [5b]from the tensioner roller (8).
Refit:
- The lower timing cover (4)
(by moving the engine).- The crankshaft pulley (2).
- Screw (3)of the crankshaft pulley.
Tighten screw (3) to 4 ± 0,4 m.daN, then angular tighten to 53°±4°, tool [4].

Engines: 6FZ - RFN
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».
If it is not, replace the tensioner roller or the timing belt and tensioner roller assembly.

ENGINECHECKING AND SETTING THE VALVE TIMING
Engine: RFK
Tensioning the timing belt.
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.
