Chara cteristics
The front axle is composed of two joint half axles with independents wheels, designed for the
suspension type Mc.Pherson.
The joints of front half axle arm are done by means of an elastic bearing (chassis side) and by
means of a suspension ball joint (wheel side)
The transmission of the motion to the wheels is done by means of two planetary a xles, not
equal, with homocinetic tripod joints.
The wheel hub is assembled in the steering knuckle by means of a sealed bearing.
The brake disks a re ventilated.

REMARK :
T he dismounting-remounting operations are identical for both half axles (specifying
that on the right side one strap is provided and on the left side two straps are provided).

DISMOUNTING
Disconnect the battery.
Loosen the front wheels attachment screws.
Lift the vehicle on an elevator with two columns.
Dismount the two wheels.
Dismount the anti roll bar attachment screws (1) on the suspension arms.
Detach the anti roll bar.
Dismou nt :
- the suspension upper ball joint screw (2) and nut on the steering knuckle;
- the upper attachment strap screw on the right/left wing lining;
- the nuts (3) and the arm a ttachment axles on the power train a nd the strap (straps);
- the arms.

REMOU NT I NG
REMARK :
Ensure the presence of t he protection pl ate (A) on the suspension ball joint axle.
Perform the operations in the following sequence:
− Arm attachment on the power train support without tightening to the required moment
the axles nuts (3) .
− Ball joint mounting in the steering knuckle
− Attachment of the ball joint screw and tightening its nut to the required moment ;
M ount the wheels, tighten the screws to the required moment, and then with the vehicle on
wheels, continue with:
– Remounting the anti roll bar by tightening to the required moment the attachment screws.
– Tightening the shaft a rm nuts a nd fixing the strap (straps) – (4) to the upper pa rt, by
tightening the screws to the required moment.
REMARK :
When remounting the attachment buffers on the anti roll bar, put inside them 1 g of
grease type MOYKOTE 33 MEDIUM.
When remounting the suspension arm axles, use new self-locking nuts.

Elastic bushings of the suspension arm
Necessary Special Tools
P. F. 601 Bushings mounting device
P. F. 602 Bushing extractor
REPLACEMENT
This operation implies bushings replacement one by one, in order to maintains their centering
as to the arm shaft. The operation is to be performed using a press (mechanical/ manual driving)
Dismount one of the bushings, by means of the PF 602 device, using a 31 mm outside diam-
eter rod.
Mount the new bushing, observing the value A =239 ± 0.4 mm.
Dismount the second bushing, proceeding in the same a.m. shown way, in order to maintain
the va lue A = 239 ± 0.4 mm
Mounting of the elastic bushings is performed by means of the device PF 601.
REMARK :
The elastic bushings are to be m ounted on the suspension arm by pressing, with
continuos pressing on the outside bushing, avoiding hammering.

Suspension ball joint
DISMOUNTIN G
Perform the same operations as for dismounting the suspension arm.
Unscrew the two attachment nuts (3) of the arm shafts, without their dismounting .
Dismou nt :
- the ball joint a ttachment screws ( 4) on the arm;
- the ball joint.
REMARK :
When dismounting the suspension ball joint off t he arm, check by visual inspection
if the corresponding holes from the suspension arm, are out of round.
If they are out of round, obligatory replace the suspension arm.
REMOU NT I NG
REMARK :
Ensure the presence of t he protection pl ate (A) on the suspension ball joint axle.
Mount the suspension ball joint on the arm, by means of the two attachment screws (4) and
tighten their nuts to the required moment.
Perform then, the same operations as for suspension arm remounting, observing the tightening
moments.
PROTECTION BELLOW S REPLACEMENT
Dismount the damaged bellows.
Clean the ball joint in the area covered by
the bellows (ball joint body and pin).
Fill the new bellows with approximate 3g
MOS
2 s pecial grease.
Mount the new bellows on the ball joint.
Place on the bellows by means of a resis-
tant thread, the fixing clip (B), then the fixing
clip A (Ø= 19).

Brake lining (pads)
REMARK :
In order to maintain the brake efficiency,
the replacement of the brake l ining (pads)
shall be made only in complete kit. Brake pads brand TEXTAR are to be used
as spare parts.
DISMOUNTIN G
Loosen the front wheel attachment screws.
Lift the vehicle by means of a two-column
elevator.
Dismount the front wheel.
Disconnect the wear sensor wire.
Remove: - the safeties of the wedges ( 1);
- the wedges, by sliding them.
D etach the caliper assembly from the fork
together with the flexible hose.
Remove:
- the brake pads from fork seats
(maintaining springs are attached with them);
- the maintaining springs from the brake
pads. REMARK :
It is forbi
dde n t o push the brake
pedal after the c alipers were
dismounted from the fork. If the brake pads are not fully used
but on their friction surface, especially
in the middle pad channel, there are
material traces, it is recommended the
cleaning of these surfaces in order to
avoid the noise when braking. Irregularly we ar of one brake pad or
wear diffe rences between t he inner pad
the outside pad, greater than 10% of the
minimum remaining l ining, impose the
kit replacement.

Checking the brake pads wear
Point of view construction, the front brake is a ventilated disc type with floating caliper and
fork (1) attached by means of the screws to the steering knuckle.
Brake linings ( 3) ( brake pads) are “TEXTAR“ type, without wear sensor.
The wear checking i s performed by comparing the mark ( P) from the caliper, with the ( C)
mark from the fork
Maximum wear of the brake lining (brake pads) is token into consideration and their obligatory
replacement is imposed, when the protuberance ( P) from the caliper ( 2) is as seen in “D” close-
up, against the middle of the channel “ C” from the fork (1).
