BUSHINGS
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.

PRELIMINARY CHECKING
Before c hecking and adjustment of the front a xle ge ometry, pe rform t he followings
operations: * The checking of tires concerning: - dimensions
- air pressure
- the state of wear;
NOTE :
The t ires must be of same t ype, with the same state of wear, ai r pressured at the
prescribed pressure.
*The check of joints: - the wear of e lastic bushings
- the steering ball joints clearance
- the wheels bearings clearance.
NOTE :
The axial clearance of the bearings must be in admissible limits. ESTABLISHING OF THE STEERING CENTRAL POINT
In order to perform a front a xle checking and adjustment, it is ne cessary t o e stablish the
centra l point in order t o avoid measurement errors.
To do that, bring the steering wheel so that device DIR 500 for steering box ra ck
blocking is enteri ng in the orifice placed at its right upper part .

HECKING OF THE FRONT AXLE ADJUSTMENT
Case 1:
The symmetry dimension “X” is correct-the value “A” is equaled distributed.
Case 2:
The symmetry dimension “X” is i ncorrect-read the value “A” on e ach side, a dds it, and
calculate the avera ge value, establishing the value for each side.
Example:
Right side value : A = 16;
Left side value : A = 10;
16 + 10 = 26; 26 : 2 = 13;
Operating the steering rods tie bar, restore the same value for both sides A = 13.
In this position, lock the rotating plates at zero poi nt.
Check in the following sequence: - camber angle;
- caster a ngle;
- parallelism;
- ball joint angle.
PARALLELISM ADJUSTMENT
Loosen t he l ock nut (1) maintaining the tie
rod of steering connecting rod (2) in a fixed
position.
Act upon t he t ie rod of steering c onnecting
rod taking into account its rotation sense of
in order to obtain the convergence or
divergence and also the fact that one of its
complete rotation leads to an axial
displacement of 1,5 mm.
OBSERVATION
The opening between the wheel’s front
and rear is measured on a F=340 mm .
After obt a ining t he c orre ct pa ra llelism ,
tighten the lock nut at the required moment
of 5 daNm.

BRAKE SHOES
DISMOUNTING
The re placement of brake shoes must
be performed in complete set, never mount
the brake shoes equipped with brake
linings of different brands and qualities. Dismount :
- t he brake drum ( see t he corre -
sponding paragraph); - the two m aintenance springs (R)
of the shoes with a brake cylinder rod (T). By means of the pliers FR05A the brake
cylinder pistons are immobilized. Remove t he return upper spri ng of the
shoes using the pliers FR03. Release the end of t he ha nd brake cable
off the hand brake lever.
Sw ing the adjustment lever (C) up t o t he
moment it c omes into contact with the re ar
wheel steering knuckle. Distance the shoes from the plate.

TEERING WHEEL POSITION ADJUSTMENT
The steering wheel adjustment on vertical, is performed as follows:
- control downwards the adjustment handle ( 3 ) placed under the steering wheel lower
casing.
-bring the steering wheel in the desired position and maintain it in this position
- control upwards the adjustment handle.
It is forbidden t o perform this adj ustment during driving.
