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).

- Apply the gauge 99395218 (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.

If the teeth of the ring gear mounted on the engine
flywheel, for starting the engine, are very damaged,
replace the ring gear. It must be fitted after heating the
ring gear to a temperature of approx. 200

°C.

The crankshaft has a locating peg that has to couple
with the relevant seat on the engine flywheel.

Position the flywheel (1) on the crankshaft, lubricate the
thread of the screws (2) with engine oil and screw them down.
Lock rotation with tool 99360351 (3). Lock the screws (2) in
three phases.
First phase: pre-tightening with torque wrench (4) to a torque
of 120 Nm (12 kgm).

Second and third phase: closing to angle of 60

° + 30° with tool

99395216 (1).

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 52) fixing the link rod. Shift

the link rod (3, Figure 52) to obtain the required
clearance.

- Lock the screw (2, Figure 52) fixing the link rod and

screws (2, Figure 53) 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.

- 1

st

phase: tightening to a torque of 80 Nm (8 kgm) with

the torque wrench (1);

- 2

α

The arrow shows the direction of rotation of the
engine when running.
Using the above-mentioned 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 through the inspection window (2).

SCHEME OF SCREW TIGHTENING SEQUENCE

SECURING ROCKER ARMS

Screw screws (1 - 2 - 3) until rocker arms are brought to
contact relating seats on cylinder head, tighten the screws
according to sequence indicated in figure operating in two
steps as indicated in successive figure.
