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
s cratched.
Use Decapjoint to remove t he re mains
of fittings that are left stuck. The ab ove produc t is applied on the
cleaning are a; wait ca. 10 minutes, then
clean by means of a wooden spatula.

AT IO N
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
commanded by pin no. 32 of the i njection cal-
culator, and on cylinders no. 2 and 3 when it
is commanded by pi n no. 1 of the same cal-
culator.
