ENGINE ASSEMBLY

10 - 31

Mount the assembly in the block, 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.

Mount the base bearing on the cylinders

block. Hal-bearing lining that are mounted on
casing are provided with oiling holes.
The bearings 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 angle 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.

Mount 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;

MOT 550

- 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.

Mount the lower casing and tighten the

screws to the required moment of 1 daNm.
Sealing is performed using RHODORSEAL
5661; the layer D must be 3 mm thick.

Do not forget to replace the two half-moon

gasket (in area A) with new ones.

Dismounting – Remounting

Mount the engine flywheel; the flywheel

attaching screws thread must be lubricate us-
ing LOCTITE FRENETANCH.

Block the engine flywheel by means of the

geared sector MOT 582 and tighten the at-
tachment screws to the required moment of 5
– 5.5 daNm.

Center the clutch disk and mount the clutch

mechanism (see chapter 20”Clutch”).

Mount the water pump (sealing is performed

using LOCTITE 518).

Apply a layer of sealant material H, 0.6 – 1

mm thick, according to the drawing.

Tighten the attachment screws to the

required moment of 1 -2 daNm.

CYLINDER HEAD REMOUNTING

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
attachment wholes, by means of a sy-
ringe.

CYLINDER 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

Wait 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 releasing 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 before lu-
bricating with oil their heads and threads.
