PR030 ENRICHING ADAPTATION IN OPERATION
PR031 ENRICHING ADAPTATION AT IDLING
RECOMMEND AT IONS No failure must be present or memorized.
Perform the steps for memorizing the adaptation values by the injection
computer.
Erase the computer memory. A t warm, when idling adjustment, observe the se paramete rs :
- If one of t hese parameters is moving towards the minimal limit, there is not sufficient petrol or there
is t oo much air.
- If one of the se paramete rs is moving towards the minimal limit, there is too much petrol or there is
not sufficient air.
(See chapter “ Enriching adaptive correction) for the exact limit values)
Ensure the cleaning condition and the good operation of :
- fuel filter
- fuel pump
- fuel circuit
- fuel tank
- air supply piping
- air filter
- spark plugs
C heck :
- Engine compressions
- Valves cle arance
- Ignition
Diagnostic – Parameters interpretation
AF TER Restart the conformity checking from the beginning.

COOLING - EXHAUST - TANK
FILLING CAP
Fuel tank
The fuel tank is having a filling cap, sealed-type, with key. The filling cap for unleaded fuel has
a filler whole incompatible with a c lassical filling gun (lead has a negative effect upon the de-
pollution system : oxygen sensor and catalyst).
In case of vehicle overturning, the anti-overturning valve is getting blocked, avoiding in this
wa y, the petrol leakage towards the carbon can.

DISMOUNTING
M ount the i mmobilizing sector MOT
582. Dism ount the clutch mechanism
attachment screws.
Dismount the mechanism and the clutch
disk.
Perform a visual checking of :
- the wear of the engine flywheel and
of the mechanism plate; - t he c ondi t i on c r own t oo t hi ng for
starter; - the sealing at c rankshaft sealing gasket
level; - the wear of the pressure bearing guide
and of the control fork;
- the conditions of the clutch shaft grooves.
Replace the damaged part s and clean the
clutch shaft grooves.REMOUNTING
D egrease the friction surface of t he engine
flywheel.
Clean the grooves of the clutch shaft.
Check the disk sliding on the clutch shaft
Mo u n t the clutch disk (with hub
protuberance ( A) towards the engine
flywheel).
Center the clutch disk by means of the
centering device AMB 1518.

Dismount the reverse driving contact (A).
In order to recover the balls and the lock-
ing springs of the 1-2 and 3-4 shafts, two
magnets placed in the C orifices are used.
Pull the control shaft towards exterior and
s eparate the crankcases
Dismount the reverse driving control shaft
and the 5-th gear. Remove the pin of the
3-4 fork by means
of the C.V. 949 device and dismount the 3-4
shaft and fork assembly .

C.V. 551
BEARING DISMOUNTING OFF THE MECHANISMS CRANKCASE
The safety ring of the bearing (the holding ring) is enlarged by means of a pair of safety pincers,
then the bearing is extracted from the crankcase by hammering towards the inside of the mecha-
nisms crankcase, by means of the C.V. 551 device.
BEARING REMOUNTING OF THE MECHANISMS CRANKCASE
Replace the safety of the bearings with a new one, then this one is introduced into its groove in
the mechanisms crankcase, so that its position is observed a s compared t o the c rankcase (the
safety shows a shoulder). The bearing is pressed from the exterior of the mechanisms crankcase towards the inside of it,
until the safety fits into the groove carved on the outer ring of the bearing. Mounting of the bearing is performed by means of the C.V. 551 device.

BEARING DISMOUNTING FROM THE CLUTCH – DIFFERENTIAL CRANKCASE
Dismount the clutch shaft bearing towards the clutch opposite direction, by means of the
C. V. 553 device.
Ensure that device is well fixed upon depressing the bearing.
BEARING REMOUNTING FROM THE CLUTCH – DIFFERENTIAL CRANKCASE
The remounting shall be performed using the same C.V. 553 device, the mounting direction of
the bearing being towards the clutch.

The stopping safety device (A) is extracted, by means of a pincers from the differential
crankcase (press on clutch crankcase in order to release the safety ring).
The differential assembly is dismounted using a press, by means of a bushing C.V. 554 (the
bushing is pressing on the differential crankcase).
Di smount the spacer washer (5) and the elastic concave washer (6).
The crown of the speedometer (8) is dismounted from the outside of the differential casing.
REMOU NT ING THE DIFFERENTIA L
Remounting of the differential assembly is performed in the reverse order of the dismounting
operations, only this time the spacer that is mounted between the lateral surface of the crown
and the support bearing, shall be positioned with the concave side towards the crown.

DIFFERENTIAL BEARINGS REPLACEMENT
DISMOUNTIN G
In order to extract the big bearing (7), of the differential from the clutch-differential crankcase,
a profiled metallic strap is used, which is pressed by means of an extension, at a press. In order to dismount the other bearing (10), first extract the safety (9), then press with a press
on the bearing by means of a sleeve with the outer diameter of 50 mm, towards the inside of the
clutch-differential crankcase.
R EMOU NT I NG
In case of the bearing (7), its cage C must
be oriented towards the opposite side of the
differential crown. In order to press this bearing into the clutch
crankcase, the C.V. 1059 device is used,
which is pressing on the outer ring of the bear-
ing.
When remounting the other bearing ( 10),
its cage C must be oriented towards the op-
posite side of the differential crown. For pressing, the 65 mm diameter sleeve
of the C.V.1059 device is used, which is
pressed on the outer ring of the bearing Remount the bearing maintaining safety.
