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 100 Nm (10 kgm).

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.

Fitting engine flywheel

Fit the sealing gasket (1), install the fitting tool 99346246 (2)
and drive the sealing gasket by screwing the nut (3).

Fit the camshaft (4), positioning it observing the reference
marks (

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.

Figure 50

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).

Replace the idle gear bushing (1) when wear is
detected. After installing the bushing, adjust it to j
58.010

± 0.10 mm.

- Apply gauge 99395215 (1), check and record the position

of the rod (3) for the transmission gear, tighten the screw
(2) to the prescribed torque.

- Remove the transmission gear (1) and tighten screws (2)

by means of proper splined wrench, to the prescribed
torque.

SECTION 3 - INDUSTRIAL APPLICATION

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 49) 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.

Using tool 99360144 (3), fasten the blocks (4) to the rocker
arms (2).
Apply the tool 99360553 (1) to the rocker arm shaft (5) 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.
