3. Obtaining S( straight line )I steering position :
IMPORTANT In order that the following checks
should be accurate, the zero setting of the turn-
tables must correspond exactly to the strnifih/
liwv position of the vehicle.
a) Place the magnetic supports C of the graduated
rule forward to its maximum extent against its
stop.
b) With the engine idling, set the manual control
to ,KJWRl n,n,,ir,ji posili, ,,,.
Check measurements Ll and L2.

The steering should return to the (( straight ahead n
position of its own accord. In this position, check that the following !wo
conditions me met.
1 ) That it is possible to insert pin A (dia =6.5mm)
into the control pinion (rwrrr poiat oi rack J
2) That the values indicated on the rear graduated
rules B ore identical.
1st case : The pin cannot be inserted :
- Slackenvscrews ( -c) and operate eccentric
i 1 i until pin inserts.
NOTE In the case where the eccentric travel
is insufficient :
- Place eccentric ot the centre of its travel.
- Slacken screws (2 ) and rotate steering shaft(!)
until pin inserts.
In the case where this last operation is unsuccess-
ful, it is necessary to move the steering clamp on
the rock control pinion.
2nd case : The values indicated on rear gradu-
ated rules ore different :
- Slacken collars ( 4) and use one of the
sleeves ( 5 1 to obtain an identical value
on Path rear graduated rules 6.
- Bring the Z~IO of graduated sections C
opposite fixed mark <( a )I of each turntable.
- Lock the graduated sections in place using screws D.

IMPORTANT NOTE
When the steering has been set in I( straight line >) position, (the marks in line with zero
on the sectors of the turntables
1 steering wheel and front wheels must not be touched throughout the whole of
the testing operation.
2. Check readings Ll and L2 ( see chapter I ).
3. Adjust the length of the telescopic rods approximately according to the front track of the vehicle, both rods
being of the some length.
IMPORTANT : Place the rods on either side of front axle so that they are parallel to each other and perpendicular
to the longitudinal axis of the vehicle and the overall
distance between them is exactly 2.48 meters.
The rods need not necessarily be at equal distance from the axle but the spacing between them is essential.
4.
To make the test :
Pivot one of the two projectors towards the front rod hnd read off on the graduated rule thr value indicated by the
luminous mark. Then pivot projector towards the rear rod and move this laterally until the snne reading is obtained
as for the front rod.
Repeat this operation with the other projector, pivotting it successively towards the rear rod and then towards
the front
rod and each time note the readings indicated by the luminous mark.
The reading shown on the rem alignment rod should be 1 to 4 graduations greater than the reading shown on the
front alignment rod which corresponds to a
toe-in between 1 to 4 mm.
NOTE Never adjust the lens between the two front and rear readings.

The crossmember supporting the steering has slots at its fixing point on the front subframe.
Any vertical movement of this crossmember alters the steering geometry.
WARNING
This operation is only to
be carried out in certain ccxses such as
-accidental impact, with repercussions on the steering system.
-work on the vehicle entoiling removal of steering crossmember.
- vehicle with poor
road stability ( p oar stright-line stability) 01 with excessive tyre weor.

used. 2. Mark position of vehicle in relation to
ground :
Secure a weighted length of string to the front
bumper. and
mark the position of the weiqht on
