COOLING - EXHAUST - TANKExhaust Assembly
ATTENTION !
Descending pipe in operation, may reach high temperatures and consequently must not
co me in contact with flammable materials which may lead to their auto-ignition.
Catalytic converter is to be mechanical shock protected.
DISMOUNTIN G
In order to di smount the noise a bsorber assembly ( 1), lift t he ve hicle on an elevator and
perform the following operation s:
Loosen the nuts ( 2) of the attachment collar between the expansion chamber ( 3) and the
noise silencer ( 1).
Di smount the thre e a ttachment e lastic supports of the noise a bsorber, on the carri age
body, rear pa rt. Release the noise silencer.
In order to dismount the assembled expansion chamber (3), perform the following operations:
Di smount the c ollar ( 4) and disengage the e xpansion chamber assembled with the de -
scending pipe.
Dismount the three elastic supports of the assembled expansion chamber.
Loosen the attachment collar nuts ( 2) and remove the assembled expansion chamber by
easy rotation and onward pulling.
In order to dismount the descending pipe assembly (6), perform the following operations:
Dismount the engine shield.
Dismoun t the catalytic converter attachment nuts ( 7) on the two studs of the exhaust manifold
flange. Dismount the attachment screws of the converter support ( 5).
For EURO 96, dismount the oxygen sensor located in upstream of the catalytic converter.
For EURO 00, dismount the oxygen sensors located in upstream, consequently, in
downstream of the catalytic converter.
Dismount the collar (4) and disengage the assembled catalytic converter from the assembled
expansion chamber.
Remove the descending pipe.
REMOU NT I NG
Perform the dismounting operations in the reverse order.
Ensure a perfect sealing between the exhaust assembly elements, using sealing paste Wurth,
on the joining area length (inside) between the noise absorber – expansion chamber (0.013 Kg);
The oxygen sensor gasket is to be replaced at each dismounting.
The tightening moment between noise absorber and expansion chamber is: 3.6 daNm.
The tightening moment of descending pipe attachment nuts on the exhaust manifold flange is:
2 daNm. Tightening moment between the catalytic converter and expansion chamber: 2.5 daNm.
All elements are to be assembled having the ambient temperature.

COOLING - EXHAUST - TANKFuel tank
IMPORTANT:
During the int erventi on on the fuel tank
and on the fuel supply circuit, at t he working
place, do not smoke and do not bring near
an y incandescent parts.
Fuel tank draining i s not implying tank
dismountin g. The access is allowed through the
vehicle interior (trunk).
Dismo unt :
-tr unk carpet;
-v isitin g whole cover (by dismounting the
three attachment screws);
- disconnect the rapid coupling A;
- adjust to exit A, an enough long hose to
be introduced in a vessel outside the vehicle.
From the fuse box located inside the engine
compartment, remove the H relay of the petrol
pump and bridge across plugs 3 and 5 of the
relay connector, ensuring the petrol pump
working (12V).
Stop the pum p working when petrol
discontin uous draining s noticed.
Detach the plugs bridge.
Mount the petrol pump relay.

Dur ing thi s operation it is
compulsory:
-not smoking and not approaching

REMOU NT I NG
Perform the di smounting opera tions in the
reverse order.
Tighten to the required moment the fuel tank
attachment screws (2.1 daNm); the thread of
the two rear attachmen t screws is to be lubricated
before mounting with Fixamed M28 (necessary
quantity – 2 grams).

Dismount the fuel tank cap.
Drain the fuel tank through the filling cap,
by means of a draining pneumatic or electric
pump. Dismount the a ttachments screws ( 1) of
the upper filling cap.
Lift the vehicle by means of the elevator.
Di smount the four attachment screws of
the fuel tank. Dismount the attachment clip ( 2) of the
aeration hose ( 4) on filling cap.
Carefully lower the tank and disconnect it:
- wiring connector;
- fuel supply pipe;
- petrol vapors re-aspiration pipe (for
petrol engines); - fuel return pipe (for Diesel engines);
Extract the aera tion hose on top of tank
crossbar and dismount the tank.

C HECKING METHOD
“ DISK RELEASE “
The checking is to be performed at idling, with warm engine. - release the clutch,
- wait for thre e seconds,
- engage the reverse dri ving (engagement must be performed without noise).
CHECKING METHOD
“ CLUTCH RELEASING FORK STROKE “
By means of a lineal perform the following operations:
- measure the distance between the fork upper part and the clutch cable support, in the
clutched position;
- measure the distance be tween t he fork upper part and c lutch cable support, in t he
clutch releasing position;
- calculate the differe nce between the t wo values (the fork active stroke) and compare i t
with the re ference value ( 29 mm).
