Mount the assembly i n the bl ock, as per
previous established sequence and check and
ensure that a 0.1 mm gauge is passing be-
tween jackets.
Dismounting – Remounting
MOT 484
Block the jackets by means of the device
MOT 484 or the clamps MOT 588.
M ount the base bearing on the cylinders
block. Hal-bearing lining that are mounted on
casing are provided with oiling holes.
The beari ngs lining are matching with the
crankshaft in two classes, as follows: Mount connecting rod bearings (connecting
rod bearings are the same) Lubricate the cranckpin and the bearings.
Mount the crankshaft and the axial bearings.
Mount the bearings caps. On the no.1 cap
(area K) apply a layer of LOCTITE 518, be-
tween 0.6 and 1 mm thick.
Tighten the bearings caps to a required mo-
ment of 2.5 daNm then to an a ngle of 43° ± 6°.
Check the axial clearance of the crankshaft,
which must be between:
*0.045 and 0.852 with wear;
* 0.045 and 0.252 without wear.

The axial bearings may have the following
thickness: 2.80, 2.85, 2.90, 295 mm.
M ount the connecting rods caps and
tighten to the required moment of 4.2 daNm.
Check:
-connecting rods lateral clearance;
- assembly rotation.
Mount: -gear and driving chain of the oil pump;
- oil pump (check the existence of the
centering bushings) and tighten the screws to
the required moment of 2.5 daNm;

- 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;
-crankshaft sealing gasket towards fly-
wheel (at no. 1 bearing) by means of the MOT
1129-01 device. Lubricate the sealing gasket external part
and lip with engine oil.

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.

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
steering pump”);
-belt or accessories belt according to the method described in chapter 07” Accessories
b elt tensioning”.
