Suspension arm
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.

- the brake pads their places in the fork, assembled with the maintaining springs;
- the caliper
- the wedges and their locks

Brake caliper
DISMOUNTIN G
Loosen the front wheel attachment screws.
Lift the vehicle by means of a two-column
elevator Dismount the wheel.
Drain the brake fluid from the reservoir
Remove the locks and the caliper wedges.
Un screw the rigid duct screw from the
brake flexible hose and detach the caliper
assembly.
REMARK :
If it is necessary to dismount the
cali per fork, di sm ount the at tachm ent
sc rews on the caliper fork.
When remounting the fork, replace the
Grower washers, tighten the screws to the
r equired moment of 6.5 daNm then seal
them with FIXAMED R 58.
RE PAI R ING
Dismount the protection gasket.
Extract the piston using a wooden wedge and
a compressed air source.
Remove the sealing gasket from its seat in the
caliper groove by means of a blade. Clean with alcohol the parts, replace t he
damaged ones, mounting being performed in the
dismounting reverse order, after previously all
parts have been oiled with brake fluid.
REMARK :
Before remounting on the fork, check the
sealing of t he assembled caliper.

Brake caliper
REMOU NT I NG
Perform the dismounting operations in the reverse order plus the following operations:
- filling of the caliper with brake fluid in order to facilitate the brake system purging;
- purging the brake system.
BRAKE CALIPER SEALING CHECKING
Connect to the caliper, a pressure gauge attached to a compressed air source.
Place a wooden wedge in order to block the piston
Create a 0.3 bars pressure in the caliper
Dip the caliper into a vessel with alcohol.
Move the piston several times to remove the air from the sealing gasket seat.
Check the sealing at various pressures, without exceeding the pressure of 2 bars.
If the brake shows air leaks by the piston, perform its dismounting.
Replace the piston, the ga sket, or the caliper body, as the c ase stands.
Perform again the sealing test.

Therefore, before mounting on the vehicle, it
is necessary to perform the shock absorbers
pressing, by alternatively shifting the shock
absorber rod (upwards a nd downwards), the
shock absorber being in vertical position. S

Spring – shock absorber assembly
DISMOUNTING SPRING-SHO CK ABSORBER ASSEMBLY OF F THE VEHICLE
Loosen the front wheel attachment screws.
Lift the vehicle by means of a two-column
elevator. Dismo unt :
- the wheel;
-t he st eeri ng knuc kle attachment
screws (1) to the shock a bsorber leg;
- the two upper attachment screws (2 )
of the shock absorber on the carriage body.
Take out the spring – shock a bsorber
assembly, by pressing on the l ower arm, in
order to avoid the shock absorber getting in
contact with the transmission bellows.
SPRING DETACHMENT FROM SHOCK ABSORBER
Place t he shoc k absorbe r on t he shoc k
absorber support (4), of the base plate (3 ) of
the SU S 600 device.
Place the compression plate (7) on the filtering
block and position the rods grips (8) on the spring
lower last but one coil. Com p re ss t he sp ri ng by a l t e rna t i ve l y
tightening the nuts (9) till release it from the lower
plate of t he shock absorber.
Dismount the upper attachment nut of the
s hock absorbe r by means of the SUS 601
combined wrench.
Take out the spring
Place the spring on the SUS 600 device shaft
(2).
Place on the shaft the lock bushing (6), the spacer (5), and tighten the crank ( 1) to the
required moment till the lock bushing (6) comes into contact with the filtering block of the shock
absorber. Loosen alternatively t he nuts (9) and take out the plate (7) and the rods grips (8).
Release the spring by means of the crank (1) and detach from the shaft (2), the filtering block
of the shock absorber, the upper plate, a nd the spring.
