aLock the slip plates of the lift.
aPosition the vehicle on a lift (see Vehicle: Towing
and lifting) .
aCheck the condition of the following components:
-track rods,
-axial ball joint linkages,
-subframe,
-lower arm rubber bushes,
-lower arm ball joints (see Front driveshaft lower
arm ball joint: Check) ,
-shock absorbers,
-tyres,
aCheck:
-the tyre size (see 35A, Wheels and tyres, Tyres:
Identification, page 35A-7) ,
-the tyre inflation pressure (see 35A, Wheels and
tyres, Tyre pressure: Identification, page 35A-
10) .
aPut the vehicle in the VODM position (vehicle in run-
ning order) (see 30A, General information, Under-
body heights: Adjustment value, page 30A-24) :
-tank full,
-vehicle empty (without luggage, etc.).
aConsult:
-the front axle geometry values (see 30A, General
information, Front axle assembly: Adjustment
values, page 30A-31) ,
-the rear axle geometry values (see 30A, General
information, Rear axle assembly: Adjustment
values, page 30A-38) .
aRefer to the user manual for the geometry tester.
aCheck the geometry using the geometry tester.
aIf there is an inconsistency between the manufactur-
er's values and the measured values:
aAdjust the front axle (see 30A, General informa-
tion, Front axle system: Adjustment, page 30A-
36)

I - MEASURING POINT
Radius under load:
-R1: Distance between the ground and the front wheel
shaft.
-R2: Distance between the ground and the rear wheel
shaft.
1 - Front height (W1): (W1) : Height between the ground and the side mem-
ber (the measuring point is located 23 mm from point B
of the yoke)
2 - Rear height (W2)

(W2) : Height between the ground and the bolt shaft of
the rear axle bearing
II - MEASURING METHODS
Measure the heights:
-R1,
-R2,
-W1 right-hand and left-hand,
-W2 right-hand and left-hand.
Special cases:
Fit a bar across the lift.1 - Plate higher than the lift:
Measure the heights (1) , (2) , (3) .
Example: (1) = 6 cm, (2) = 8 cm, (3) = 10 cm.
Calculate the height Wx:
Wx = height (1) + height (3) - height (2) ,
Wx = 8 cm.
2 - Plate lower than the lift:
Measure the heights (1) , (2) , (3) .
Example: (1) = 8 cm, (2) = 10 cm, (3) = 4 cm.
Calculate the height Wx:
Wx = height (1) + height (2) + height (3) ,
Wx = 22 cm.
III - VEHICLE IN RUNNING ORDER POSITION
VODM (Vehicle in working order) position:
-Tank full,
-Empty vehicle (without luggage, etc.).
139112
Note:
For the measurement of W1 and W2, take into
account the height differences between the plates
and the final drive.
Note:
The value of Wx to be entered into the geometry
bench is the average of the W1 heights, right-hand
and left-hand and of the W2 heights, right-hand and
left-hand.
Note:
If the measuring points are located in empty space
(betw een the rails of the lift), use a bar.

2 - Bleed using a new syringe.
aKeep the clutch pedal in the upper position using a
strap attached to the steering wheel to ensure conti-
nuity of the hydraulic circuit during the bleed opera-
tion.
aRemove the bleed plug from the clutch slave cylin-
der.
aConnect a transparent pipe of sufficient length to the
bleed hole (at least thirty centimetres) in order to
place it at the same height as the reservoir.
aOpen the bleed screw.
aFill the brake fluid master cylinder reservoir until
brake fluid flows out of the bleed screw.
aConnect a new hydraulic circuit bleed syringe
filled with a useful volume of 60 ml of approved
brake fluid to the end of the transparent pipe.
aSlowly inject the entire contents of the syringe into
the hydraulic clutch circuit without injecting any of
the air from the top section of the syringe.
aClose the bleed screw.
aRemove the transparent pipe from the bleed hole.
aRefit the bleed plug.
aTop up the brake fluid level in the master cylinder
reservoir.
aDisengage and engage the clutch quickly around
twenty times.
aCheck that the clutch system is operating correctly.
aRepeat the bleed operation if necessary.
aCheck the adjustment of the switch. (see 37A, Me-
chanical component controls, Clutch pedal
switch: Removal - Refitting, page 37A-52) (37A,
mechanical control elements).IV - BLEED PROCEDURE IF PARTS OF THE
HYDRAULIC CIRCUIT ARE REMOVED.
a
Note:
Take care not to disrupt the adjustment of the
clutch start of travel switch.
Note:
The transparent pipe must remain at the same
height as the master cylinder reservoir to prevent
air from entering inside the clutch circuit.
WARNING
The master cylinder pipe must be disconnected
from its take-off point on the br ake fluid reservoir,
to avoid any foreign matter penetrating inside the
hydraulic brake circuit.
WARNING
Prepare for the fl ow of fluid and protect the sur-
rounding components.
Note:
Prefill the hydraulic circuit pipe equipped with a
filter.
Position the filter head facing downwards to
ensure that it fills.
