NOSING-INTERPRETING THE STATES
Remark:
The testing of the battery and the charging circuit can be done with “TECHNIC CLIP”

CLAPPER POSITION
MEMORIZED VALUE FOR

SUGGESTIONSNo defect should be present or memorized.
The contact is set or the engine is started.
The value is
memorized at limit
or fa ilure to detect
the free pedal
po sition, or failure to
detect the completely
pushed down
position Check if the mechanic limitation of the potentiometer has been
a
ltered.
Check the command of the acceleration (friction, obstacles).
Check the resistance of the clapper potentiometer.
Change potentiometer if necessary.
Check the insulation, the continuity and the absence of contact
re sistance along the circuits:
pin 43 of calculator ♦ pin C of clapper potentiometer
pin 74 of calculator ♦ pin B of clapper potentiometer
pin 75 of calculator ♦ pin A of clappe r p otentiometer.
Remedy if necessary.
Th e po sition, of the
clapper is fixed
Check the resistance of the clapper potentiometer during the
operation of the clapper.
If the resistance varies, check the electric circuits connected to
the potentiometer.
If the resistance does not vary, check if the potentiometer is
mechanica lly coupled to the clapper.
Change the potentiometer if necessary.
AFTER REPAIRPerform again the conformity test.

COOLING - EXHA U ST - FUEL TANK
DISMONTING
The battery is disconnected.
The tube s of the radiator are stopped up with the MOT 453 de v i ce s .
Dismount the hoses from the radiator by means of the elastic collar pliers MOT 1202-01.
The two screws of the stand are taken off the upper traverse of the radiator and the radiator
is taken off. The radiator is emptied and the cooling liquid is retrieved.
R
EMOUNTING
Check the existence of the supporting bushings.
The radiator is mounted.
The jack s for the fixing on the radiator are mounted, as well as the radiator stands, and the
fixing sc rews are fastened (0,57 daN).
The MOT 453 devices are taken off.
The tube s that have been taken off are mounted back and the collars are tightened.
Note : When mounting, line up the marks from the hoses and the related parts.
The ba ttery is connected.
Th e filling and the draining of the cooling circuit is done.
Tightening moments:
- the screws for the radiator stands (M6- 2 pieces) - 0,57 daN.

Disconnect the battery.
Mark the steering wheel position (straight line driving position).
Dismount the connection screw (1) between the deformable lower shaft and the steering
wheel shaft. Loosen the screws of the front left wheel.
Lift the vehicle by means of a two-column elevator.
Dismount the left front wheel.
Dismount the connection screw (2) between the deformable lower shaft and the gear shaft
of the steering box. Dismount the sealing gasket (3) from the cowl panel.

ATTENTION !
It is forbidden the damaging of the lower shaft and of the connection parts from the
steering system (steering box gear, steering wheel shaft) when dismounting/remounting
the lower shaft.
REMOUNTING
Clean the steering box gear shaft and grease it with grease UM 185 Li2 or UM 180 Li2.
Perform the dismounting operations in the reverse order. Tighten the connection screws between
the lower shaft and the steering box gear shaft, consequently between the lower shaft and the
steering wheel shaft to the required moment of 1.4 daNm.
