ENGINE ASSEMBLY
10 - 30
The arrow marked on the piston head must
be oriented towards engine flywheel. The c onnecting rods ha ve no mounting
direction, but the ha lf-bearings spurs are to
be positioned on the same part. In order to assemble the piston and the
connecting rod, proceed as follows: -place the bushing B 13 on the support
and attach the piston (with the arrow oriented
upwards) on the bushing;
Dismounting – Remounting
- lubricate the centering guide and the
piston bolt with engine oil;
- check t he free gliding of the piston
bolt and the piston positioning.
When the connecting rod end is reaching
the necessary temperature (about 250 °C),
proceed to the ra pid of the piston bolt, as
follows: -introduce the centering guide in the
piston; - position the connecting rod i n the
piston;
-press till end the piston bold.
Check if the pi ston bolt is remaining re -
tired as against the piston outer diameter for
each of the connecting rod position in the pis-
ton.
Rings mounting
Mount the rings on the pi ston in the
following sequence: -
oiling ring ( 3);
-s ealing ri ng (2) w ith the mark “TOP”
upwards; -compression ri ng (1) with t he mark
“TOP” upward. The compression and sealing rings are to be
mounted with the slots disposed at 90° against
de bolt’s axle and displaced between them with
180°. The oiling ring is to be mounted with the
slot oriented at 45° against the bolt’s a xle.
The rings slots being adjusted, shall never be
reworked.
Lubricate the pistons with engine oil.
M ount the assemblies “connecting rod-
piston-rings” in the cylinder’s jackets, by means
of the mounting bushing. Mount the sealing gaskets on the cylinder
jackets.

ANTI-POLLUTION
Pet rol vapors re-aspiration
OPERATING PRINCIPLE
The communication of the t ank with t he
atmosphere is done through the carbon can. The petrol vapors are retained when they are
passing through the active carbon from the carbon
can. By means of a purging valve controlled by a
RCO signal issued by UCE injection, the petrol
vapors are re-aspired through piping by the intake
manifold.
The flow section of the purging valve is
variable, subject to the balance given by the
magnetic field created by supplying the purging
valve coil and the power of the spring ensuring
the valve closing.
RE-ASPIRATION CONDITIONS
The can-purging valve is controlled by pin
4 of the UCE injection, in the moment when:
-w ater tempera ture > 20 ° C;
- air temperature > 10 ° C;
- engine is running over a certain im-
posed charge; -valve potentiometer is not in the posi-
tion acceleration pedal not pressed.
By using the CLIP tester, it is possible the
reading of the RCO value (opening cyclic
ratio).
The purging valve is closed for a value
smaller than 0.7%. OPERATION CHECKING OF THE
CAN PURGING VALVE
A defective operation of the petrol vapors
re-aspiration system, may lead to an unstable
idling or even to the engine stopping. First of all, check:
-circuit conformity (see the operating
diagram)
-piping condition between the can and
the fuel tank (sealing, circuit clogging).
The (B) piping coming from the tank shall
be clogged.
Connect a manometer (-3…+3 bar) at the
(M) connection for communication with the
atmosphere and check at idling if there is
depression. Is there depression?
YES – Set conta ct off. Usi ng a
vacuum pump, apply a 500 - mbar depression
at the (A ) piping connection of t he purging
valve. The value of the red depression must
not have a variation more than 10 mbar
wi thin 10 seconds.
