CHECKING AND SETTING THE VALVE TIMING
Engine : XFX
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.

CHECKING AND SETTING THE VALVE TIMING
Engine : XFX
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 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
