ADJUSTING THE GEAR LEVER
(I) the lever should be inclined approximately 3’
towards the rear in relation to the vertical axis
XX’ of the vehicle.
If not :
remove dust cover ( 1 ),
remove three screws ( 2 ),
shift cover ( 3 ) to obtain correct position of
gear lever.
NOTE : Should it be impossible to effect odjust-
merit by means of cover (3 ), make necessary
adjustment at control shaft hall joint (5 ).
Tighten three screws (2 ).
Refit dust cover (1 ). b)
the gear lever should be located in the longitu-
dinal axis YY’ of the vehicle.
If not :
= Adjust selector shaft boll joint (4) to obtain
this position.
NOTE :
When adjusting boll joints (4) 01 i 5) it is
imperative that the flats (v)
on each shaft ore properly aligned.

( Front wheel toe-in )
1. Prrpnmtion oi whirlr~. Positior,

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.

This operation is to be
carried out on a level
rmd, in the absence of any wind. The vehicle pulls ta the right :
- Slacken
both nuts ( l), rotate eccentric ( 2 )
towards the left.
- Tighten nuts ( 1). The vehicle pu’lls to the left :
- Slacken both nuts ( 1 ), rotate eccentric i 2) towards
the right.
- Tighten nuts ( 1)

VARIATION OF FEEL as a function of the speed of the vehicle
The variation in feel is obtained by a variable mechanical force being applied to control shaft A

Contact point
STEERING TO LEFT OR RIGHT Towards
a)
Mechanical principle :
Control shaft A is in mesh with pinion B
Pinion B is in one piece with Cam H against which piston F, through roller G. applies pressure. according to
the following
- Angle of rotation of shaft A ( r,//‘c’cf oj
tjcct,utric )
* Pressure exerted on piston F ( I nricrhlc> /)r(,ssur( supplic~d In stc,~,ririg go('~'nlor J
Pressure of piston F is being exerted in the hollow on cam H, which tends to maintain the steering in the
(( straight-ahead !j position‘
The cam and roller contact point is situated away from the O-O axis; a force is applied against the effort of
the driver,
which therefore increases the feel.
