Checking the setting (continued).
Remove:
the accessories drive belt.
the accessories drive pulley.
the lower timing cover
(3).IMPERATIVE: The magnetic track should show no signs of damage
and should not be approached by any other source of magnetism.
Reposition the screw (2).
Remove tool [3].
Rotate the engine by means of the crankshaft pinion screw (2)(clock
wise), to bring it to the pegging position.
Position the tool [4].
Peg the crankshaft pinion (1), using tool [5].
Peg the high pressure pump pinion, using tool [5].NOTE:Index «a»of the roller tensioner must be centred within the
area «b».
Check the correct positioning of index «a».
Remove tools [4]and [5].
Rotate the engine ten times.Fit the tools
[4]and [5].
If pegging is not possible, carry out the operation to remove/refit the
timing belt
(see corresponding operation).

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 crank
shaft pinion.
Refit the screw (2).

Setting the timing (continued).
Hold the tensioner roller, using a hexagonal spanner at «b».
Slacken the screw (9).
Remove the timing belt (10).
Refitting.
IMPERATIVE: Check that both the tensioner roller and the fixed roller turn freely
(no tight spots). If this is not the case, replace the rollers.
Fitting of the pulle
ys.
Camshaft pulley: Tighten to 4,3 ± 0,4 m.daN.
Fuel high pressure pump pulley: Tighten to 5 ± 0,5 m.daN.
The crankshaft pinion is located without a screw at the end of the crankshaft.
Fitting of the rollers.
IMPERATIVE: Check that the tensioner roller turns freely (no tight spot).Otherwise, replace the rollers.
Guide roller:Tighten to 4,5 ± 0,4 m.daN.
Tensioner roller :Pretighten to 0,1 m.daN.
Check the condition of the seals at the camshaft and at the crankshaft pinion.
