Setting the valve timing (continued)
Refit.
- Check that the camshafts and the crankshaft are correctly pegged.
- Check that the rollers and the water pump pulley are turning freely. (No tightness)
- Loosen the camshaft pulley screws by a 1/4 turn.
- Make sure that the pulleys are turning freely on the camshaft hub.
- Turn the camshaft pulleys in a clockwise direction, to end of slots.
WARNING : Respect the direction of fitting of the belt : facing the timing, the inscriptions
on the belt should be readable the correct way up.
- Fit the timing belt on the crankshaft pinion.
- Position the tool [6].
- Position the timing belt in the following sequence :(Belt well tensioned).
- The roller (26), the pulley (18), the pulley(17),
- Keep the timing belt well tensioned :
- Refit the guide roller (16),tighten to 8 ± 0.8 m.daN.
- Position the timing in the following sequence :
- The camshaft pulley (15), the camshaft pulley (14), the tensioner roller (24), the water pump
pulley, and the guide roller(27).
NOTE :When positioning the belt on the camshaft pulleys, turn these clockwise so as to engage
the next tooth. The angular displacement of the pulleys should not be more than the equivalent of
one tooth.

Setting the valve timing (continued)
Adjusting the timing belt tension.
- Pivot the plate (25) of the tensioner roller (24), using a spanner (type FACOM S.161).
- Engage the screw(21)on the plate (25).
- Tighten the screws (21)and (22), tighten to 2,5 ± 0,1 m.daN.
- Position the belt under maximum tension ; pivot the tensioner roller (24),using a spanner
(type FACOM R 161).
- Tighten the nut (23) of the tensioner roller (24) , tighten to 1 ± 0,1 m.daN.
- Check that the camshaft pinion screws are not at the end of slots.
(By loosening one screw).
- Otherwise, restart the operation of positioning the timing belt.
- Tighten at least2 screwsper camshaft pulley to 1 ± 0,1 m.daN.
- Remove the tools [1], [2]and [4].
- Rotate the crankshaft 2 turnsin a clockwise direction.
IMPERATIVE : Never turn it back.
- Peg the crankshaft, using tool[2], and the camshaft pulleys, using tool [1].
- Untighten the nut(23)of the tensioner roller(24).
- Adjust the belt tension, pivoting the roller (24)using tool(type FACOM S.161).

CHECKING AND SETTING THE VALVE TIMING
Engine : XFX
Setting the valve timing (continued)
- Align the marks «c» and «d», without detensioning the timing belt.
(Failing this, restart the operation of adjusting the belt tension).
- Hold the tensioner roller (24).
- Tighten the nut(23), tighten to 1 ± 0,1 m.daN.
- Check the position of the tensioner roller.
- Remove the tools[1], [2]and [4].
- Turn the crankshaft 2 rotationsin the direction of engine rotation.
IMPERATIVE : Never turn it back.
- Peg the crankshaft, using tool [2].
- Check the roller position (24)(the alignment of the marks «c»and «d»should be correct).
- Peg the camshaft pinions, using tool [1].
- If the peg [1]goes in, loosen the camshaft pulley screws by45°.
- If the peg [1]does not go in, then loosen the camshaft pulley screws by 45°and manoeuvre the
hub using tool[5]until pegging is achieved.
- WARNING : Check that the camshaft pinion pulleys are not at the end of slots. Otherwise, restart
the operation of positioning the timing belt.
- Tighten the camshaft pinion screws to 1 ± 0,1 m.daN.
- Remove the tools [1]and [2].
- Refit the panel (20), the screws (19)and tighten to 4 ± 0, m.daN.
- Complete the refitting of all components.

Checking the setting of the valve timing.
Peg :
- The engine flywheel, using tool [3]. (From under the vehicle).
- The camshaft, using tool [5].
WARNING :On removing screws (6), (7), (9), and (5) of the timing cover, refit the
screw(5) equipped with a spacer (thickness :17 mm).
Tighten to 1,5 ± 0,1m.daN.
(The screw (5)is one of the screws fixing and sealing the water pump).
WARNING : Should it be impossible to peg the camshaft, check that the offset
between the camshaft pinion hole and the pegging hole is not more than 1 mm,
with the help of a mirror «a» and a Ø 7 mm screw.
