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).
