Position the dial gauge with a magnetic base (1) with the
(flat-based) rod positioned on the roller (2) for the rocker
arms which controls the exhaust valve for cylinder no. 3 and
apply a pre-loading of 6 mm.

Camshaft is timed if conditions below are found at cam lift
values 4.70

± 0.05:

1) hole identified with two notches (5) is visible through

manhole;

2) fixture 99360612 (1) through housing (2) of engine rpm

sensor inserts in hole (3) on engine flywheel (4).

In case conditions shown in Figure 61 and shown at paras 1
and 2 are not found, operate as follows:

1) release screws (2) securing gear (1) of camshaft to as to

make control gear and camshaft independent;

2) conveniently operate on engine flywheel so as to obtain

conditions indicated at paras 1 and 2, Figure 61,
considering that cam lift value must remain unchanged;

3) lock screws (2) and repeat control as already described;

4) lock screws (2) at required torque.

Figure 62

Rotate crankshaft to check conditions below:

1) hole identified with two notches (5) is visible through

manhole;

2) fixture 99360612 (1) through housing (2) of engine rpm

sensor inserts in hole (3) on engine flywheel (4).

115064

To recover the clearances, rotate the crankshaft in
a clockwise direction until the opening with the two
references is passed and then rotate in the opposite
direction to produce the conditions described
above.

NOTE

Using tool 99360341 (3, Figure 46), rotate crankshaft
clockwise till dial gage arrow reaches minimum value (max
cam lift), after which it no longer varies.

Zero set dial gage.

Rotate engine flywheel anticlockwise till dial gage reads
camshaft cam lift value = 4.70

± 0.05 mm.

During the measurement the rod for the dial gauge
should always be perpendicular to the engine axis
and NOT to the surface of the head.

Fit the flywheel (4) so that the tooth marked with the arrow
(

↑) is in line with the sensor housing (6).

Rotate crankshaft and bring cylinder n.1 piston to compression
phase at TDC: Rotate flywheel opposite to regular rotation
direction by 1/4 of rev.

Rotate flywheel again in regular rotation direction till hole
identified by double notch (2) shows through inspection hole
under flywheel cover box.

Insert tool 99360612 (1) in flywheel sensor housing (3).

Insert tool 99360613 through phase sensor housing (6) on
tooth machined on tune wheel.

In case tool (6) is difficult to insert, unlock screws (5) and orient
tune wheel (4) to properly match the tooth.

Lock screws (5).

Install fuel supply pipeline (1) from high pressure pump to rail.

Lock nuts at 35 Nm torque.

Install timing cover (1) and lock retaining screws (2) at
required torque.

Pipes previously removed ca no longer be refit.
Change them.

NOTE

After high-pressure pipe installation, during the
following 20 hours of work, frequently check engine
oil level (IT MUST NOT INCREASE).

Install gear (7) of high pressure pump and lock nut (8) at
required torque.

When refitting, use the flat washer (PN 17095914)
in conjunction with the nut (8) replacing the one
supplied with BOSCH pump CP3.

Adjustment of clearance between rocker arms and
intake/exhaust valve control crosspieces must be performed
with utmost care. Bring to blast phase cylinder to be adjusted;
the valves of this cylinder are closed while the symmetric
cylinder valves are balanced. Symmetric cylinders are 1-6; 2-5
and 3-4.

In order to perform these operations correctly, refer to
procedure and table below.

Use a polygonal spanner to release lock nut (1) of rocker
arm adjustment screw (2).

Insert filler gage (3) having same value of operating
clearance shown in “Characteristic and data“ tables.

Use special spanner to lock/unlock adjustment screw.

Check that filler gage (3) slides with a low friction.

Lock nut (1) retaining the adjustment screw.

In order to correctly carry out adjustments above,
it is mandatory to perform the sequence indicated
in the table, checking exact positioning at each phase
by means of pin 99360612.
