After the tu ning of the distri bution and the adjustment of the rocker-arms, the
following are further re-m ounted: -the cylinder-head cap, fitted with a new fitting; the screws are tightened at 1 daNm;
-the water-intake conduit and t he oil-level gauge guide (with new watert ight-
sealing ri ngs); -the cap of the distribution;
-the pulley of the crankshaft; the screw is first tightened at 2 daNm, then at 68
o+/-6o.
C
AUTION!
If the screw is not duly tightened, it c an come undone, which c an result in t he oi l-
pump not being operated and the distribution being disrupted, thus causing serious
damage to the engine.
-the intake and exhaust collectors: the screws are tightened at 2.5 daNm;
-the belt(s) of accessories: the same method as that for the distribution belt is used.
The stretching values are :
* alternator belt 263+/-10Hz
* Air-Comditioning (A.C) compressor belt 222+/-10Hz.

The system is made up of:
- electronic control unit;
- double ignition coil;
- four sparking plugs;
- spark plugs.
DES CRIPT IO N OF FUNCT IO NING PRINCI PL E
Accordi ng to the data received from
various sensors, but essentially according
to the revolution ratio and the load of t he
engine, the electronic control uni t will de-
termine the ignition advance; it will also
identify the cylinders that are set at the
upper center point and, consequently, will
command the re spective coil. This c auses the spark at the level of the
two cylinders t hat are at the upper center
point, thus interrupting the m ass-setting of
the respective coil. T
HE CO IL
The system c ontains a doubl e c oil, con-
trolled by the calculator.
Coil no. 2 has an electric connector (1) with
four ways, whi ch si m ultaneousl y produc e
s parks at cylinders nos. 1 and 4, when it i s

culator, and on cylinders no. 2 and 3 when it
is commanded by pi n no. 1 of the same cal-
culator.

SUGGESTIONS There shou
ld be no defect present or memorized
Check the resistance of the step-by-step engine for the idle mode adjustment.
Change it if necessary.
Check the insulation and the continuity of the cabling along the circuits:
- pin 12 calc ulator ♦ pin B step-by-step engine
- pin 41 calc ulator ♦ pin A step-by-step engine
- pin 42 calc ulator ♦ pin C step-by-step engine
- pin 72 calc ulator ♦ pin D step-by-step engine
Remedy if necessary, and then go on with the diagnose, watching the tolerance value of
the idle mode rotation ratio.
The id le mode rotation
ra tio< minimal limit. The id le mode rotation ratio is too small.
-Check th e functioning of the enrichment adjustment.
-Clean the air supply circuit (clapper body, step-by-step engine) as they seem to be dirty.
-Ch eck th e oil level of the engine (too high a level causes splash lubrication)
-Ch eck the pressure of petrol (see if it is not too small)
-Ch eck en gine compression with the “CLIP TEHNIC” tester
-Ch eck the adjustment of the rocker-arms and the settling of the distribution.
-Ch eck the ignition system
-Ch eck the in jectors.
If all the above are correct, then the step-by-step engine will have to be replaced.
AFTER REPAIRPerform again the conformity test.

REMOUNTING
In order to be corre ctly positioned on the
s haft, the bearing must be pressed to achieve
the value L = 118 +/- 0.2 mm between the
b ackside of the bearing and the shaft
extremity. This value is obtained by means
of the PF 1331 device, when mounting, its
extremity is at the level of the shaft .
IMPORTANT
In order to avoid the deformation of the bearing, which includes a sealing gasket (annular
oil seal), the pre ssing effort must be constant (do not hammer).

GENERALITIES
GENERALITIES
The purpose of the a ir conditioning unit i s to produce a decrease of t he temperature in the
passengers compartment a nd to obtain a l ower value t emperature compared to the external
environment one, reducing in the same time the air moisture.
MAINTENANCE
For a vehicle equipped with air conditioning, it is recommended a frequent checking of the
refrigerating agent level. During the year it is recommended:
- the checking of the refrigerant fluid filling;
- the cleaning and the air-blowing of the condenser and the cooling radiator fins;
- the checking of the condensation removal pipe on order not to be clogged.
For important leakage repair, for any components replacement (compressor, condenser, etc)
and if moisture was noticed in t he air conditioning circuit, the dryer filter tank is to be replaced
and the unit draining is to be performed. The same is valid also in case the conditioning circuit
remains open without protection covers more than 10 minutes.
IMP ORTANT
Duri ng winter, it is recommended the frequent start of the system, in order to pro-
long the lifetime of the compressor and of the whole system.
The vehicle equipped with an air conditioning system shall be not exposed for more
than 20 minutes i n painting c abin where there are temperatures higher than 80 °C.
It is obligatory the use of the refrigerating agent and compressor oil type prescribed
by the manufacturer. It is absolutely forbidden to perform welding on the elements of the air condition
circ uits. The filling of the air conditioning system can be pe rformed only by m eans of charging
units and observing the instructions of the manufacturer. For mechanical or body
operations it is recommended pi ping protection in order to avoid their disconnection
by accident. Avoid the drip of the oil compressor on the painted vehicle body.
For component replacement implying the circuit draining, it is absolutely necessary
the use of new parts and of a special oil for compressor.
