Setting the timing.
Remove the upper timing cover (1).
Rotate the engine by means of the crankshaft screw (2).
NOTE:The pegging hole is located under the crankshaft bearing cap cover.
Peg the engine flywheel, using tool [3].
Remove the lower timing cover (3).
Uncouple the exhaust line from the manifold.
IMPERATIVE: Uncouple the exhaust line in order to avoid damaging the front flexible pipe. Twisting,
pulling and bending the front flexible pipe reduces its life.
Remove:
- The engine speed sensor (6).
- The belt retaining stop (5).
- The screw (2).
- The crankshaft pinion (4)
(with its magnetic track «a»).
IMPERATIVE: The magnetic track should show no signs of damage and should not be approached
by any other source of magnetism. Should this not be adhered to, it is essential to replace the
crankshaft pinion.

ENGINECHECKING THE VALVE TIMING
Engines: 9HX - 9HY - 9HZ
Checking the timing (continued).
Peg the camshaft at «c», using tool [2]
(oil the pegs).
WARNING: The magnetic track should not show any sign of damage and should not be
approached by any other magnetic source.
Peg the crankshaft at «d», using tool [3].
ESSENTIAL: Should it not be possible to peg the camshaft, check that the offset between
the camshaft pinion hole and the pegging hole is not more than 1 mm. If it is more, repeat
the operation to position the timing belt
(see corresponding operation).
Note : The index «e»of the dynamic tensioner roller should be centred in the interval «f».
Check the correct positioning of the index «e».
If it is not correct, repeat the operation to tension the timing belt
(see corresponding operation).
Remove tools [2]and [3].
Refitting.
Peg the flywheel at «b», using tool [1].
Remove the screw (8).
Refit the upper timing cover (11), lower timing cover (10), the accessories drive pulley (9), the screw (8).
Tightening method for the screw (8):
- Pre-tighten to 3 ± 0,3 m.daN.- Angular tighten: 180° ± 5°.
Remove the tool [1]and complete the refitting.
IMPERATIVE: Carry out the operations that are necessary following a reconnection of the battery
(see corresponding operation).
