DISMOUNTIN G
Drain the fuel tank ( 4)
Disconnect the battery.
Remove the trunk carpet.
Di smount the tank visiting cover from the
three attachment screws.
Di sconnect the e lectric connector f the fuel
pump assembly a nd detach from clips the
connection from the fuel supply pipe. Take out the spare wheel and release it
together with its support.
Remove the filling cap ( 2) and dismount the
two attachment screws of the upper filling cap.
Lift the vehicle on a two columns elevator.
Dismount the four-attachment screws (6) of
the fuel tank on the carriage body, then maintained
in tilted position, disconnect the rapid coupling
on the anti-overturning valve ( 7).
D etach from clips collar ( 3) of the aerating
pipe on the upper filling cap.
Release the fuel tank together with the aerating
connection. Dismount the thermal screen ( 5) off the three
maintaining clips. Dismount the attachment clip ( 1) of the filling
cap muff on the lower filling cap.
Dism ount t he fue l pum p a sse mbly by
dismounting the attachment nut by means of the
MOT 1397 device.
REMOUNTIN G
Perform the dismounting operatio ns in the
reverse order. The t ightening moment of t he fuel tank
attachment screws on the carriage body is of
2.1 daNm and the tightening moment for fuel
pump assembly attachment nut, is of minimal
7daNm .
REMARK :
Collar (1) is for single use only.
When remounting, use a new click collar
(1 ), for the attachmen t of the lower filling cap
connection on the fuel tank.

30Braking system purging
The air existence in the hydraulic circuit may be noticed by an elastic displacement of the brake
pedal, sometimes even, close to the floor. This fact is more evident with the engine running.
GENERAL RE COM M E NDATIONS
· Always use for completion or total changing the brake fluid SAE J 1703 , DOT 4.
· In case of changing the brake fluid it is necessary to wash the system with industrial alcohol.
· During the purging, the brake fluid from the reservoir must not go down bellow the MINIM
level marked on the reservoir.
To perform the purging, one person will stay on the driver place, to press the brake pedal and
the other one will perform t he purging at purging points, using a 500 ml vessel, a tra nsparent
plastic tube and brake fluid for completion.
REMARK:
The brake fluid obtaine4d during performing the purging operation IS NOT TO BE
REUSED, but after 48 hours, to avoid air bubbles introduction in the hydraulic circuit.
PR OCED UR E
Place on the purging screw, a transparent tube with its end in a vessel with brake fluid a nd
proceed as follows : - press the brake pedal slowly;
- dismount the bleeding screw, maintaining the full stroke of the pedal;
- tighten the bleeding screw;
- slowly release the brake pedal.
Repeat the same procedure until complete cease of bubbles.
Pr oceed in the same way also for the other purging places.
T ake into consideration the existence all the time of the brake fluid in the reservoir.
OBSERVATION : Before beginning the purging procedure, dismount the I.C.P. contact
from the brake pump that it will be remounted at the end of the operation, brake pedal released.
It is important to observe the following sequence of the purging points:
1.Main brake cylinder;
2. Left rear wheel brake cylinder;
3. Right rear wheel brake cylinder ;
4. Caliper of front right wheel ;
5. Caliper of front left wheel;
6. By-pass circuit through main cylinder purge.

Brake lining (pads)
REMARK :
In order to maintain the brake efficiency,
the replacement of the brake l ining (pads)
shall be made only in complete kit. Brake pads brand TEXTAR are to be used
as spare parts.
DISMOUNTIN G
Loosen the front wheel attachment screws.
Lift the vehicle by means of a two-column
elevator.
Dismount the front wheel.
Disconnect the wear sensor wire.
Remove: - the safeties of the wedges ( 1);
- the wedges, by sliding them.
D etach the caliper assembly from the fork
together with the flexible hose.
Remove:
- the brake pads from fork seats
(maintaining springs are attached with them);
- the maintaining springs from the brake
pads. REMARK :
It is forbi
dde n t o push the brake
pedal after the c alipers were
dismounted from the fork. If the brake pads are not fully used
but on their friction surface, especially
in the middle pad channel, there are
material traces, it is recommended the
cleaning of these surfaces in order to
avoid the noise when braking. Irregularly we ar of one brake pad or
wear diffe rences between t he inner pad
the outside pad, greater than 10% of the
minimum remaining l ining, impose the
kit replacement.
