Position the crankshaft with the pistons 1 and 6 at the top dead
centre (T.D.C.).
This situation occurs when:
1.
The hole with reference mark (5) of the engine flywheel
(4) can be seen through the inspection window.
2.
The tool 99360612 (1), through the seat (2) of the engine
speed sensor, enters the hole (3) in the engine flywheel (4).
If this condition does not occur, turn the engine flywheel (4)
appropriately.
Remove the tool 99360612 (1).
- Fit the idle gear (1) back on and lock the screws (2) to the
required torque.

- Apply the gauge 99395219 (1). Check and adjust the
position of the link rod (3) for the idle gear. Lock the screw
(2) to the required torque.

Fit the camshaft (4), positioning it observing the reference
marks (
→) as shown in the figure.
Lubricate the seal (3) and fit it on the shoulder plate (2).
Mount the shoulder plate (2) with the sheet metal gasket (1)
and tighten the screws (5) to the required torque.

Position the gear (2) on the camshaft so that the 4 slots are
centred with the holes for fixing the camshaft, without fully
locking the screws (5).
Using the dial gauge with a magnetic base (1), check that the
clearance between the gears (2 and 3) is 0.073 — 0.195 mm;
if this is not so, adjust the clearance as follows:
- Loosen the screws (4) fixing the idle gear (3).
- Loosen the screw (2, Figure 49) fixing the link rod. Shift
the link rod (3, Figure 49) to obtain the required
clearance.
- Lock the screw (2, Figure 49) fixing the link rod and
screws (4, Figure 51) fixing the idle gear to the required
torque.

Fit the seals (1) (2) (3) on the injectors.
Before refitting the rocker-arm shaft assembly, make
sure that all the adjustment screws have been fully
unscrewed.
Apply the tool 99360553 (1) to the rocker arm shaft (2) and
mount the shaft on the cylinder head.

Mount:
- The injectors (1) and, using a torque wrench, lock the
bracket fixing screws to a torque of 26 Nm.
- The crosspieces (2) on the valve stem, all with the largest
hole on the same side.

Lock the screws (2) fixing the rocker-arm shaft as follows:
- 1
st
phase: tightening to a torque of 80 Nm (8 kgm) with
the torque wrench (1);
- 2

phase: closing with an angle of 60
° using the tool
99395216 (3).
Mount the electric wiring on the electro-injectors.

Using the tool, turn the engine flywheel (1) in the direction of
rotation of the engine so as to take the piston of cylinder no.1
to approximately the T.D.C. in the phase of combustion.
This condition occurs when the hole with one reference mark
(4), after the hole with two reference marks (5) on the engine
flywheel (1), can be seen.
