- the crankshaft closing casing; the
sealing is performed using LOCTITE 518 (
the layer H must be 0.6 – 1 mm thick);
- sealing gasket from crankshaft clos-
ing casing (lubricated with oil) by means of
the MOT 550 device;

CYLINDER HEAD REMOU NT I N G
Dismount the blocking device of the cyl-
inders jackets.
Mount: - cylinder head centering bushing on
the block; - cylinder head new gasket with the
marking “ TOP” upwards;
- cylinder head (lubricate the screws
ends and threads with engine oil).
REMARK:
In order to obtain a correct tighten-
ing of the cylinder head screws, remove
the oil that may be in the cylinder head
attachm ent whol es, by means of a sy-
rin ge.
CYL INDER HEAD TIGHTENING
METHOD
1. GASKET PRE-SETTING Tighten all screws to the required moment
of 2 daNm, then to an angle of 97° ± 2°,
observing the order indicated in the bellow
drawing.
Dismounting – Remounting
W ait for 3 minutes, stabilization time.2. CYLINDER HEAD TIGHTENING
Cylinder head tightening is to be performed
successive for the screws groups 1-2, 3-4,
5-6, 7-8 and 9-10; - unscrew 1-2 screws until total release;
- tighten the 1-2 screws to the required
moment of 2 daNm, then to 97°±2°
- repeat the releasin g and tightening op-
eration for the screws groups 3-4, 5-6, 7-8
and 9-10.
The cylinder head is not to be re-tight-
ened.
Continue by mounting: -rockers ramp, positioning item 1 from
the shaft towards distribution.
Tighten the ramp attachment screws 2 to the
required moment of 2.3 daNm, not be fore l u-
bricating with oil their heads and threads.

DISTRIBUTION ADJUSTMENT
The belt tensioning is to be performed only
with cold engine (environment ambient tem-
perature).
On the belt backside, there is an arrow
indicating the rotation directio n and two marks
for setting. Line up the L item from the crankshaft gear
with the M fix item (item from camshaft gear
upward). AT T E N T I ON!
The camshaft gear may have five
marks; only the rectangular shaped mark
of one tooth is representing UDP (Upper
D ead Point), the ot hers are used for rock-
ers adjustment .
Dismounting – Remounting
Line up the i tems from the belt with t he
ones from the gears, observing the mounting
direction and starting from the crankshaft
gear. Place the MOT 1505 device captor (in
the position shown in the drawing) at a dis-
tance of 5-10 mm against the belt.
Any of the two captors may be used with
the condition that both captors are not in the
same time in front of the belt. Make vibrating the belt by means of a finger
(the measurement is validated by a device “bip”)
Tighten the belt, by acting upon the tightening
roller by means of the MOT 1135-01 device,
until obtaining of a value between 210 and
275 Hz. Block the tensioning roller and tighten its nut
to the required moment of 3 daNm.
Rotate then, five and a half turns the crankshaft
(cylinder no2 in the rockers adjustment position).
Dismount the tensioning roller nut.
Tighten again the distribution be lt unt il
obtaining of a value between 145 and 185 Hz.
AT T E N T I ON!
If the v alue of 275 Hz is exceeded, the
belt can not be used and its replacement is
necessary.
Obligatory tighten the rollers nut 0 to the re-
quired moment of 5 daNm.
If not, this may unloose ri sking t he e ngine
damage.
REMARK:
Once a belt is dismounted, t his is not to
be remounted, but replaced.

Dismounting – Remounting
Continue to mount:
- cylinder head cover equipped with a ne w cylinder head gasket, tighten the attachment
sc rews to the required moment of 1 daNm;
- water inlet pipe and the oil dipper guide (with new sealing rings);
- distribution casings;
-cr ankshaft pulley or pulleys; tighten the pulley hub screw to the required moment of 2
daN m, then to 68° ± 6°.
ATTENTION!
If the screw is not properly tighten, this may unloose, which may lead to the oil pump
no n-drive and to the distribution derangement, consequently to engine damaging.
- intake manifold and exhaust manifold, tighten the attachmen t screws to the required mo-
ment of 2.5 daNm;
- compressor and/or power steering support;
- alternator (see chapter 16”Alternator”);
- compressor- for vehicles equipped with air conditioning (see chapter 62 “Air condition-
ing”); -power steering pump-for vehicles equipped with power steering (see chapter 36 “Power
