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.

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.

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

± 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.

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 168) fixing the link rod. Shift
the link rod (3, Figure 168) to obtain the required
clearance.
- Lock the screw (2, Figure 168) fixing the link rod and
screws (4, Figure 170) fixing the idle gear to the required
torque.

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 (2) and, using a torque wrench, lock the
bracket fixing screws to a torque of 26 Nm.
- The exhaust brake cylinders (1) and (4) and, using a
torque wrench, fix them to a torque of 19 Nm.
- The crosspieces (3) on the valve stem, all with the largest
hole on the same side.
