30Front axles checking and adjustment
THE SEQUENCE OF THE OPERATIONS
Due to the geometric c onception of the front axle, the modification of one of one-side
angles (camber, ball joint, parallelism) has no major impact on the val ue of other side
angles (caster being the one with higher i nfluence). The modifi cation of t hese angles does not occur during ve hicle exploitation, but only as a
consequence of a vehicle accident.
In order to check the front axle angles, it is important to observe the following sequence: - placing the vehicle on rotating plates;
- braked vehicle;
- suspension checking for placing the vehicle at its free height;
- ensuring that front wheels are such disposed for straight line driving;
- attachment of the optical devices on the vehicle, observing the manufacturer instructions.
RE PARTITION CHECKING AND ADJUSTMENT
Check the “X” dimension symmetry of the
connecting rods.
Reading of the “A” value on the scale.

3. TRACTION ACCESSORIES SET ( CAR 504)
CELETTE bench is equipped with a traction accessories set CAR 504, which allows the op-
erator to achieve different anchoring when a body strengthening is performed (pict. 5).
4. SET OF MZ TOWERS AND SPECIFIC SUPPORTS ( CAR 503 +CAR 507)
This kit represents a MZ system and consists of two elements: - kit of 22 MZ t owers, universal CAR 503 – (see pict. 6);
- kit of specific supports CAR 507. Each MZ tower has an arrow, which settles
its orientation on the cross bar and a MZ
reference (fig 7) Example – MZ 080, where:
MZ - measurement on OZ axle of the vehicle,
080 – MZ tower height (in mm).
In the same way as f o r COMPAC T
assembly , the arrow (1) marked on the specific
support must be oriented towards the bench
front part, as follows: -attachment on the right part of the
mobile bench; - attachment on the left part of
the mobile bench.
REMARK :
The MZ tow ers may be used also for the checking/ straightening of the carriage
bodies of other vehicles types, being then necessary the purchasing of the specific
supports for each type of vehicle.
