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.

jacket-sealing part .
Preparation of the pi st o n- and-jacket set
The parts supplied in the collection are
matched. Do the line-up marking of the set, from
A to D, in orde r to keep the pa rts matched.
Remove completely the anti-rust fi lm;
never era se the parts.
These engines are equipped with rub-
ber rings for jacket watertight-sealing;
these rings ensure only watertight-seal-
ing condition. The jackets lean directly
against the cylinder cra nkcase; extra
height X is achieved by the manufac-
turer.
The checking-up of the jacket extra -
height is done in the fol lowing way: -the jackets a re pl ace din the block
without their sealing-ring;
-extra-h eight X is checked by
means of the MOT.251 and MOT.252-01
devices.

The jackets are positioned such a way as:
-the difference be tween two succes-
sive jackets should be max. 0.05 mm; -the extra-height should be placed i n
ascending order between cylinder s 1 and 4.
-the extra-height X must be within
0.02 mm and 0.09 mm;
-in case there is an erroneous extra -
height, it is c hecked a gain by means of a
new set of jackets in orde r to see whether
the cause is the block or the jacket; if not,
check the theore tical values of both the
block and the jackets. The A, B, C, D set is done over with
the correct extra -height obtained, then the
jackets, the bolts and the pistons are num-
bered from 1 to 4 (no. 1 towards the fly-
w heel), so that t he concorda nce with t he
corresponding connecting rods is found.
The axes of the pistons a re m ounted by
means of the MOT 574-22 device.
The axes of the pistons are fixed in the
rod, and loose in the pistons.
Check i f the axes of t he pistons slide
freely in the new corre sponding pistons.
The axis of piston E is mounted on the
mounting axis A.
The C centring device is screwed up to
the end and then unscrewed a quart er of a
rotation.
THE CYLINDER CRANKCASE
In order to heat the connecting rods an
electric range of 1 500 W is used.

THE INFLUENCE OF THE FRONT AXLE ANGLES ON THE ROAD
BEHAVIOR (VEHICLE COMPORTMENT) AND ON TYRES WEAR
CAMBER ANGLE 0
0 +/- 30’
It is formed by the wheel plane with the vertical that crosses the wheel axis.
A difference higher that 1° between the two angles leads to :
- the deviation from the trajectory that must be adjusted by means of the steering wheel.
- abnormal wear of the tires and bearings.
The angle is not adjustable.
THE BALL JOINT ANGLE 12
045’ +/- 30’
It is formed in transversal plane between the axe connecting the attachment point of the
shock absorber with the ball joint center and the vert ical passing through the wheel axis.
The ba ll joint angle i s genera ting a ne gative offset, allowing the maintaining of the vehicle
route when the braking is unequal distributed. The angle is not adjustable.
THE CASTER ANGLE 2
030’
It is formed in longitudinal plane, between the axis connecting the attachment point of the shock
absorber with the suspension ball joint center and the vertical axis passing through the wheel axis. A difference higher than 1° between the two angles leads to : - the deviation from the trajectory that must be adjusted by means of the steering wheel.
- a normal wear of the tires.
The angle is not adjustable.
STEERING BOX POSITIONING
The steering box must be at a certain height from the attachment points of the steering auxiliary
connecting rod ball joints. The position of the steering box (choking) is influencing the variation
of the parallelism. The steering box is mounted in the position for which the variation is minimal.
The modification of t he para llelism between left side and right side leads to: - the deviation of the vehicle, in one sense, upon accelera ting;
- the deviation of the vehicle in the opposite side upon braking.
- the deviation of the tra jectory on the hilly ground;
- the premature wear of the tires.
The horizontally of the steering box is ensured by the producer.
PARALLELISM
( TOE-IN OR ANGULAR SPREAD ANGLE )
It is measured in horizontal plane as a differen ce between the front and rear part of the same axle wheels.
The wheels are divergent. The value of the opening is between 0 – 2 mm (1 +/- 1 m m).
ATTENTION:
A too much opening causes the wear of the tires on the inner pa rt of the camelback.
A too much closing causes the wear of the tires on the exterior part of the camelback.
The para llelism is adjustable by rotating the tie bar of the steering connecting rod.
