Refit (continued)
- Refit the belt (10)on the pinion (12).
- Hold the belt(10)with tool [3].
- Position the belt (10)in the following order :
- The guide roller (11), the inlet camshaft pinion(9), the exhaust camshaft pinion (8), the water pump(5), the
tensioner roller (6).
NOTE :Make sure that the belt (10)is as flush as possilble with the outer face of the various pinions and rollers.
- Remove the tools [3]and[1].
T
iming belt.Adjusting the tension.- Turn the roller(6)in the direction of the arrow «b» ; using an Allen key at «a».
- Position the index «c»in its maximum setting at «d».
IMPERATIVE : The index «c» must stand proud of the notch «f» by an angular value of 10°. If it does not,
replace the tensioner roller (6) or the timing belt and the tensioner roller (6)
Bring the index «c»to its adjusting position «f»by turning the tensioner roller (6)in the direction of the arrow «e».
WARNING: The index«c»must not stand proud of the notch «f»: if it does, restart the timing belt tensioning
operation.
IMPERATIVE : The tensioner roller (6) must not turn while its fixing is being tightened up. If it does,
recommence the adjusting operation.

Adjusting the tension (continued).- Tighten the screw (7) of the the tensioner roller(6) to 2.1 ± 0.2 m.daN.
IMPERATIVE : The hexagonal drive of the tensioner roller (6) must be at 15° below the level of the cylinder
head gasket «g». If not, replace the tensioner roller (6) or the timing belt and the tensioner roller (6).
Refit (continued).
- Remove the tools [1]et [2].
- Turn the crankshaft 10 timesin the normal direction of rotation.
IMPERATIVE : No pressure or outside action must be brought to bear on the timing belt.
- Peg the inlet camshaft pulley, using the tool [1].
Checks.
Timing belt tension.
IMPERATIVE : Check the position of the index «c», it should be facing the notch «f». If the position of index «c»
is not correct, restart the adjustment of its position.
Positioning of the crankshaft.
- Fit tool [2].
- As long as it is possible to fit tool[2], continue with the refit operations.
IMPERATIVE : If it is not possible to fit tool [2], reposition the flange (14).

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.
