Setting the timing.
Perform the preliminary operations for checking the timing up to removing tool [1]at «a»for immobiling the
engine flywheel.
Refit screw
(8).
Rotate the crankshaft to bring the camshaft towards its pegging point.
Peg the camshaft, using tool
[2](oil the pegs).
WARNING: Do not press or damage the track which is the target for the engine speed sensor (14).
Peg the crankshaft at «b», using tool [3].
Remove:
The timing protector
(13).
The engine speed sensor
(14).
Slacken the screw
(12)of the tensioner roller, keeping it slack with the aid of a hexagonal spanner at
«c».
Detension the belt by pivoting the tensioner roller
(clockwise).
Remove the timing belt, commencing with the coolant pump pinion.
Peg the pulley
(15), using a 5 mmdiameter peg at «d».

Setting the timing (continued).
Chec
ks (continued).
Reposition the timing belt, belt at «e»well tensioned, in the following order:
Guide roller
(17).
Camshaft pulley
(16).
Fuel high pressure pump pulley
(15).
Coolant pump pinion
(18).
Tensioner roller
(19).
Remove the
5 mmdiameter peg at «d».
Adjusting the fitting tension of the belt.
Action the tensioner roller (19)to align the marks «f»and «g», avoiding detensioning the timing belt,
with the aid of a male hexagonal spanner, at
«c».
If this is not successful, repeat the operation to tension the belt.Hold the tensioner roller in position
(19).
Tighten the tensioner roller, tightening to
3,7 ±0,3 m.daN.
Check the position of the tensioner roller
(the alignment of the marks «f»and «g»should be correct).
Remove tools
[2]and [3].
Turn the crankshaft
six rotations(clockwise).

Refit the screw (10).
Rotate the crankshaft six times (clockwise).
IMPERATIVE: Never turn it backwards.
Peg the camshaft at «c», using tool [2](oil the peg).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 bet
ween 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 «d»Check the correct positioning of the index «e».
If it is not correct, repeat the operation to tension the timing belt (see corresponding operation).

That the rollers and the coolant pump pulley turn freely (without play and without tight
spot).
That there are no signs of oil leaks (at the crankshaft and camshaft seals).
That there are no leaks of coolant fluid(at the coolant pump).
That the track of the engine speed sensor target (15)is not damaged or scratched.
Replace any components that are defective (if necessary).
