Apply gage 99395222 (1), check and adjust position of
connecting rod (3) for relay gear, lock screw (2) at required
torque.
Refit relay gear (2) and lock screws (1) using six-splined
spanner at required torque.
The relay gear (1) bushing can be replaced when
worn out. After securing bushing, grind it to reach
dia. 58.010
± 0.10 mm.
NOTE
Rotate the crankshaft with the tool 99360341 (3, Figure 53)
so that the opening marked with two references (5) is visible
from the lower inspection window in the flywheel cover
casing.
In this condition, insert the tool 99360612 (1) via the housing
(2) for the engine rpm sensor in the opening (3) in the engine
flywheel (4).

Rotate the tool (1) 99395223 in order to insert the pin (3) in
the opening (2, Figure 47) in the head. Fasten the tool (1)
99395223 using two M8x1.25 bolts (2).
Fit the camshaft drive gear (1) so that the fastening openings
in the shaft are aligned with the slots (2) in the drive gear.
Position the gear (1) taking care to position the spokes (4) as
illustrated. This operation is necessary in order to be able to
fit the flywheel correctly which can only be fitted in one
position in relation to the gear.
Tighten the fixing bolts (3).
Install crosspieces (1) on valve rod.
Apply tool 99360558 (1) to rocker arm shaft (2) and install
shaft on cylinder head.
Lock retaining screws at required torque.
Before refitting rocker arm shaft assembly, check
that all adjustment screws have been fully unlocked.

Fit the high pressure pump gear (7)tightening the nut (8) to
torque.
Use the flat washer (PN 17095914) in conjunction with the
nut replacing the one supplied with the Bosch CP3 pump.
Fit the flywheel (4) so that the toothe marked with the arrow
(
→) is in line with the sensor housing (6).
To check that the position is correct, insert tool 99360613 in
the timing sensor (6) housing.
Proceed with tightening the bolts (5).
Remove the tools 99395223, 99360612 and 99360613.
Secure special tool 99360341 (3) to gear casing.

The arrow indicated engine rotation direction.
Use tool above to rotate engine flywheel (1) in
engine rotation direction to bring cylinder 1 piston
approx. to TDC in blast phase.
This condition is reached when hole with notch (4),
following hole with two notches (5) drilled on
engine flywheel (1), is visible through manhole (2).

The exact position of piston no.1 at TDC is obtained when,
in conditions described above, tool 99360612 (1), through
engine rpm sensor housing (2), inserts in hole (3) drilled on
engine flywheel (4).
Otherwise, rotate engine flywheel (4) to adjust its orientation.
