RECOMMENDATIONS - PRECAUTIONS (AL 4 AUTOMATIC GEARBOX)
Engines : 6FZ - RFN - RHZ
Procedure to be followed prior to carrying out repairs on AL4 autoactive gearbox

GEARBOX
DRIVESHAFTS
If a gearbox malfunction occurs, there are two possible configurations
depending on the seriousness of the fault :
- Gearbox in back-up mode with a replacement programme of
(the fault values are taken in substitution).
- Gearbox in back-up mode with an emergency programme
(3rd hydraulic).
WARNING : In the emergency programme, an impact is felt when
changing P/R, N/RandN/D.
Réception client.
Discuss with the customer, to find out all the malfunction symptoms..
Oil quality – Oil level.
If the gearbox has suffered a serious fault resulting in a malfunction or
the destruction of a clutch, the oil will overheat and become
contaminated with impurities : the oil is said to be «burnt».
This is characterised by a black colour and the presence of an
unpleasant smell.
ESSENTIAL : The gearbox must be replaced.Oil quality.
See corresponding operation.
An excessive oil level can result in the following consequences :
- Excessive heating of the oil.
- Oil leaks.
An insufficent level causes the destruction of the gearbox.
Top up the level of oil in the gearbox (if necessary).
Check using a diagnostic tool.
Read the fault codes (engine and gearbox).
Absence de codes défauts.
Carry out parameter measures, actuator tests and a road test.
Presence of fault codes.
Carry out the necessary repairs.
Delete the fault codes.
Carry out a road test to check the repair and, if need be, modify the
gearbox ECU parameters (this is essential after an initialisation of the ECU).

L1
The dimension«L1» for checking front height is between the level of
the front subframe «b» and the wheel axis «a».
This method eliminates all the variations in measurement due to :
Different wheel fiittings.
Vehicle loading.
Wear or incorrect inflation of tyres.
(Measuring from the wheel axis : tool 8006-T)
AXLE GEOMETRY
General adjustment conditions
Rear height Front height
NOTE : After each movement of the vehicle body, and before each mea-
surement :
- Move the vehicle slightly forwards and backwards, by turning the road
wheel by hand.- Check the tyre pressures.
- Release the handbrake.
- Place the manual height control in the «NORMAL» position.
- Engine running.
L2
The dimension«L2»for checking rear height is between the measuring
zone «b» and the wheel axis «a».
H1 = R1 - L1
H1 = Front height(± 6 mm).
R1 =Wheel radius(mm).
L1 = Theoretical dimension between the level of the front subframe and
the wheel axis.H2 = R2 + L2
H2 = Rear height (± 6 mm).
R2 = Wheel radius(mm).
L2 = Theoretical dimension between the measuring zone on the cross-
member support and the wheel axis.

HANDBRAKE (Adjustment)
Adjustment
- Remove the rear ashtray from the handbrake console.
- (1) Nut for adjusting the tension of the handbrake
cables.
- Raise and support the vehicle with the front wheels
hanging free.
- Check the correct routing of the brake cables under the
vehicle.
- Apply and release the handbrake 10 times.
- Set the handbrake to the 5th notch.
- Tighten the nut (1) until the front brakes are applied.
- Pull the handbrake lever vigorously4 to 5 times.
- Set the handbrake to the 5th notch.
- Check that the front brakes are applied.
- With the handbrake released, check that the wheels
can be turned freely by hand.
- Lower the vehicle.
- Refit the rear ashtray to the handbrake console.

BLEEDING AND FILLING THE BRAKING SYSTEM
Bleeding, filling (continued).
With the bleeding apparatus
- Connect the bleeding apparatus [1] on the brake fluid reservoir (1).
- Adjust the apparatus pressure to 2 Bars.
For each circuit :
- Connect a transparent tube onto the bleed screw, submerge the other end of the tube in a clean container.
- Open the bleed screw, wait until the fluid is flowing out without air bubbles.
- Close the bleed screw.
- Remove the bleeding apparatus [1].
- Check the brake fluid level(Should be between «DANGER» level and«MAXI» level).
- Fill if necessary with the approved and recommended synthetic brake fluid.
Without the bleeding apparatus.
NOTE : Two operators are necessary.
For each circuit :
- Apply the brake pedal to place the circuit under pressure.
- Connect a transparent tube onto the bleed screw, submerge the other end of the tube in a clean container.
- Open the bleed screw, wait until the fluid is flowing out without air bubbles.
- Close the bleed screw.
- Remove the tool [1].
NOTE : Recommence the process a second time if that is necessary.
- Check the brake fluid level, (Should be between «DANGER»level and «MAXI»level).
- Fill if necessary with the approved and recommended synthetic brake fluid.

SPECIFICATION - IDENTIFICATION : SUSPENSION SPHERES
Special features
Identification.
- Fitting of new slimline spheres with multilayer membranes, stone grey in colour.
- It is forbidden to recharge or overhaul this type of sphere.
- The number marked on the suspension sphere is the reference no. of the component and not the Part No.
- The two-figure number marked on the suspension sphere indicates the initial inflation pressure value.
Example :
- The pressure value of this type of suspension sphere is given merely as a guide.
- When checking, the value read could be higher than the nominal value.
NOTE : Suspension cylinders on the same axle should be equipped with the same type of membranes.
Tightening torques for these spheres : 2,7 ± 0,5 m.daN.
