Safety sign :
1. THE DISMOUNTING OF VEHICLE COMPONENTS CASE .
When there are not available four columns elevators, two columns elevators may be used, in
this case, lifting slides shall be placed under the floor closing plate, at the supporting points level
of the vehicle jack.
2. THE PARTICULARLY CASE OF DISMOUNTING – REMOUNTING OF THE

DISTRIBUTION BELT TENSIONING
Cold engine (ambient temperature).
Mount the new belt, the distribution being at setting point (P.M.S.).
Place the tensioning cam and tighten t he distri bution belt by means of t he MOT 1135-01
device.
Block the tensionin g cam.
P lace the reading head of the MOT 1505 device in the measuring area ( at a distance of 5…
10 mm from the belt); Any of the two captors may be used on the understanding that not both of
them are simultaneou sly in front of the belt.
Make the distribution belt vibrating ( the measurement is validated by a ”bip” of the device).
Tighten the belt, by acting upon the tensioning cam, until obtaining a value within the range
210…275 Hz.
Block the tightener and tighten its nut at the required moment of 3 daNm.
Rotate 5 and a half turns the crankshaft.
Unscrew the cam nut.
Tighten again the belt until obtaining a value between 145 and 185 Hz.
Obligatory tighten the tensioning cam nut at 5 daNm.
NOTE
If the value is higher than 275 Hz, the distribution belt is to be replaced with a new one.

For the values checking of the front axle angles, consequently the rear axle angles, the vehicle
must:
- to be placed with the wheels on the rotating plates ( of the bench ) being in horizontal plane;
- to ensure its braking;
- to check its suspension for vehicle setting at its free height;
- to compress its front axle at half loading ( by means of the compressing device DIR 500);
- to check its suspension for vehicle setting at its free position;
- steering brought at middle point and the steering box blocked in this position;
These op erations are followed by the optical device attachment on the vehicle, observing the
instructions of the steering angles checking bench manufacturer.

The following are to take off:-the cylinder head cap;
-the intake and exhaust collectors;
-the cylinder head screws, except the
sc rew where the centring jack is; this one
is only loosened;
-the c ylinder head is re volved round
the screw which was left in place; -the cylinder he ad is taken off;
-t he j a c ke t -m a inta i ni ng de vi c e -

.To be mounted:
-the rocker arm ramp:
-the oil-sealing of the cam-shaft;
-the flange of the cam-shaft ;
-the pi nion of the c am-shaft , which is
blocked with MOT 799 - 01 ;
-the cam-shaft;
-the stand of t he thermostat;
-the sparking plugs;
-the springs of the valves;
-the valves;
-the oil-seals of the valves, by using the
MOT. 1335 pincers.
The cylinder head is cleaned of the fit-
ting which is left stuck to it.
It is very important not to ge t the po-
sit io nin g surface of the fittings

Avoid introducing foreign bodies
into the oil grooves and tubes; you may
risk blocking up the holes of the rocker
arms and rapidly deteriorating the
cams an d the gliding parts of the
rocker-arms.

E-MOUNTING
Oil all the parts.
Mount the valve oil-seal rings no. 2 by
means of a tubular-wrench of 11 size onto
the valve guides no. 3;
Mount in the fol lowing order:
-the washers no. 1 at the base of the
valve springs;
-the new valves no. 4.
-the springs no. 5 are identical for
both intake and exhaust; -caps no. 6;
Compress springs no. 5, then m ount the

The axes of the pistons are taken apart .
The piston is placed on i ts stand, after
positioning the piston bolt (a xis) with the
release hole (t wo lines T for position-find-

Preparation of the pi st o n- and-jacket set
The parts supplied in the collection are
matched. Do the line-up marking of the set, from
A to D, in orde r to keep the pa rts matched.
Remove completely the anti-rust fi lm;
never era se the parts.
These engines are equipped with rub-
ber rings for jacket watertight-sealing;
these rings ensure only watertight-seal-
ing condition. The jackets lean directly
against the cylinder cra nkcase; extra
height X is achieved by the manufac-
turer.
The checking-up of the jacket extra -
height is done in the fol lowing way: -the jackets a re pl ace din the block
without their sealing-ring;
-extra-h eight X is checked by
means of the MOT.251 and MOT.252-01
devices.

The jackets are positioned such a way as:
-the difference be tween two succes-
sive jackets should be max. 0.05 mm; -the extra-height should be placed i n
ascending order between cylinder s 1 and 4.
-the extra-height X must be within
0.02 mm and 0.09 mm;
-in case there is an erroneous extra -
height, it is c hecked a gain by means of a
new set of jackets in orde r to see whether
the cause is the block or the jacket; if not,
check the theore tical values of both the
block and the jackets. The A, B, C, D set is done over with
the correct extra -height obtained, then the
jackets, the bolts and the pistons are num-
bered from 1 to 4 (no. 1 towards the fly-
w heel), so that t he concorda nce with t he
corresponding connecting rods is found.
The axes of the pistons a re m ounted by
means of the MOT 574-22 device.
The axes of the pistons are fixed in the
rod, and loose in the pistons.
Check i f the axes of t he pistons slide
freely in the new corre sponding pistons.
The axis of piston E is mounted on the
mounting axis A.
The C centring device is screwed up to
the end and then unscrewed a quart er of a
rotation.

In order to heat the connecting rods an
electric range of 1 500 W is used.

The watertight-sealing is done with RHODORSEAL 5661; girdle D must be 3 mm thick.
Do not forget to replace the two crescent-shaped fittings (in the A are a) with new
ones.
-the fl ywheel: beforehand oil t he face for t he pl acing of the flywheel on the crank-
s haft, using LOCTITE AUTOFORM; apply on the screws one drop of LOCTITE
FRENETANCH and tighten them at 5 - 5.5 daNm, after having blocked the flywheel
by means of the cogged sector MOT 582.
-the clutch (be cautious about the centring): scre ws are tightened at 2 daNm;
