For the values checking of the front axle angles, consequently the rear axle angles, the vehicle
must:
- to be placed with the wheels on the rotating plates ( of the bench ) being in horizontal plane;
- to ensure its braking;
- to check its suspension for vehicle setting at its free height;
- to compress its front axle at half loading ( by means of the compressing device DIR 500);
- to check its suspension for vehicle setting at its free position;
- steering brought at middle point and the steering box blocked in this position;
These op erations are followed by the optical device attachment on the vehicle, observing the
instructions of the steering angles checking bench manufacturer.

The combustion head is not restricted. Adjustment of rocker a rms is done only in cool
mode, and onl y when t here are engine interventions which have an i nfluence on their play. The adjustment values are:
-for intake: 0.10
-for exhaust: 0.25

PRELIMINARY CHECKING
Due to the geometr ic conception of the front axle, the modificati on of one of one-
si de angles (castor, camber, ball joint) has no major impact on the value of other side
angles (the parallelism being the one directly influenced). The m odification of t hese a ngles doe s not oc cur duri ng vehicle exploitation, but onl y as
a consequence of a vehicle accident.
It is import ant to observe the following sequence : - placing the vehicle on rotating plates;
- braked vehicle
- suspension checking for pl acing the vehicle at its free height;
- establishing the steering centra l point and steeri ng box blocking.
- attachment of the optical devices on the vehicle, observing the manufacturer
instructions.
REPARTITION CHECKING AND ADJUSTMENT
Check the “ X” dimension symmetry of
the connecting rods.
Reading of t he “ A” value on the scale.
