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 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.
60571
- 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.
