Di sconnect the wiring c onnector from t he
reverse driving contact. The right-side planetary transmission is un-
coupled as follows:
-the brake-stirrup set is dismantled;
-disconnect the wire for the brake pads
wear indicator; -the t wo screws for fixing the shock-
absorber of the steering-swivel stand are taken
off;
The steering-swivel stand is tipped up and
the planetary t ransmission is taken out from
the planetary pinion of the gearbox;
The l eft-side planetary transm ission is un-
coupled as follows:
-the steering-swivel screw-nut is dis-
mantled; -t he scre ws for fi xi ng t he pl a neta ry
transmission on the gearbox a re taken off; -the brake-stirrup set is dismantled;
-the e lectric wire of the wear-and-abra -
sion light-i ndicator is taken off; -the t wo screws for fixing the shock-
absorber of the steering-swivel stand are taken
off; -the steeri ng-swivel stand is t ipped up
and the planetary tra nsmission is taken out; The fuse-box in the engine compartment
is dismantled.The following are disconnected: -connector 1 from the UCE injection
(pull flap 2, then disconnect);
-the front cabling of the engine;
-the connector of t he shock-sensor;
-the ventilator connector;
-the mass wire on the gearbox.
The battery protection screen is dis-
mantled.
The following are taken off:-the linking pipes coming from the ra -
diator, by using the pincers for elastic pipe-
collars MOT.1202-01B ;
-the linking pipes coming from the de-
gassing vessel, by using the pincers for elas-

DIAG
NOSING-INTERPRETING THE STATES
The idle mode rotation
ra tio > maximal limit. The id
le mode rotation ratio is too great.
- Chec k the oil level of the engine
- Chec k the good functioning of the atmospheric pressure sensor.
- Check the tubes connected to the admission collector.
-C heck the fittings of the admission collector
- Check the watertightness fittings of the clapper body
- Check the watertightness of the power-brakes.
- Chec k the presence of the nozzles of the oil-vapour re-aspiration circuit
- Chec k petrol pressure.
- Check the adjustment of the rocker-arms and the settling of the distribution.
If all the above are correct, then the step-by-step engine will have to be replaced.
Perform again the conformity test

BRAKE GASKETS
NOTE
In order to maintain the brake efficiency,
the replacement of the brake pads shall be
made only in complete kit.
Never fit brake pads of diffe rent makes
and different qualities .
DISMOUNTING
Lift t he vehicle by means of a two columns
elevator;
Dismount the front wheel;
Disconnect the wear sensor wire;
Dismou nt : - the safety of the wedges (1);
- the wedges, by sliding them.
Detach the caliper assembly from the fork
together with the flexible hose;
Remove : - the elastic blades - the brake pads
Remount :- the brake pads their places in the fork;
- the elastic blades;
- the caliper;
- the wedges and their locks.
Reconnect the wear sensor wire.
Pr ess several times the brake pedal.
Mount the wheels.
Get down the vehicle from the elevator the
ground. NOTE
It
is forbidden to push the brake pedal
after the calipers were dismounted from
the fork. If the brake pads are not fully used but
on their friction surface, especially i n the
middle pad c hannel, there are material
traces, i t i s recommended t he cleaning of
these surfaces in order to avoid the noise
when braking.
REMOUNTING
Push the c aliper pi ston by means of the
FR 500 s pecial t ool.

BRAKE CALIPER
DISMOUNTING
Lift the vehicle by means of a two columns
elevator.
Dismount the wheel.
Disconnect the wear sensor wire
Drain the brake fluid from the reservoir
Remove the locks and the caliper wedges;
Unscrew the rigid duct screw from the brake
flexible hose and detach the caliper assemb ly.
NOTE
If it is necessary to dismount the
caliper fork, unscrew the two attachment
s crews M 12.
When remounting the fork, replace the
Grower washers, tighten the screws at the
r equired moment of 6.5 daNm then seal
them with FIXAMED R 58. REPAIR
ING
Dismount the protection gasket.
Extract the piston using a wooden wedge and
a compressed air source. Remove the sealing gasket from its seat in the
caliper groove by means of a steel blade. Clean with alcohol the parts, replace t he
damaged ones, mounting being performed in the
dismounting reverse order, after previously all
parts have been oiled with brake fluid.
NOTE
Before remounting to t he wheel, c heck
the sealing of the caliper assembly.
