DISMOUNTING – THE SIDE TO THE GEARBOX
The right side
Due to t he solution assumed by the manufa cture r, the t ransmission j oint (the t ulip of the
transmission) with the transmission shaft of the gearbox shall be performed only by mea
the grooves.
The dismounting of the transmission, the side to t he gearbox, shall be performed by
axial displacement - extract the transmission tulip from the transmission shaft.
The left side
Drain the oil of the gearbox.
Di smount :
- the thre e screws for fixing the bellows – lid assembly on the gearbox;
- the tra nsmission, the side to the gearbox. FRONT TRANSVERSAL TRANSMISSION

REMOUNTING – THE SIDE TO THE GEARBOX
The left side
Engage the t ransmission GI joint in the ge arbox (the transmission position as horizontally
as possible).
Mount the thre e attachment screws of the bellows lid on the gearbox.
The right side
Grease the t ulip fra me grooves (the grooves area) and t he tra nsmission shaft of t he
gearbox with transmission oil.
Engage the transmission GI joint (the tulip) on the transmission shaft of the gearbox
(the tra nsmission position must be as horizontally as possible).
REMOUNTING – THE SIDE TO THE WHEEL
For both sides
Engage the transmission in the steering knuckle, this one being necessary to freely enter,
so that threaded area of the steering knuckle is allowing to remounting the transmission nut.
Pe rform then the dismounting opera tions in the reverse orde r.
Ob serve the tightening moments.
Remount the brake disk assembly.
Refill the gearbox with oil.
Pr ess several times the brake pedal to enable caliper piston coming in contact with the
brake pads.

Usi ng a pre ss, e xt ract t he assembl ed
tripod, sustained it on an e xtractor, FACOM
U 53 G type, protecting the tripod clogs.
Before extra cting, mark the position of
the trip od compar ed to the t ransm issio n
shaft end.
Dismount the bellows - deflector beari ng
in the same manner l ike t ripod dismounting.
REMOUNTING
In order to be corre ctly positioned on the
s haft, the bearing must be pressed to achieve
the value L = 118 +/- 0.2 mm between the
b ackside of the bearing and the shaft
extremity. This value is obtained by means
of the PF 1331 device, when mounting, its
extremity is at the level of the shaft .
IMPORTANT
In order to avoid the deformation of the bearing, which includes a sealing gasket (annular
oil seal), the pre ssing effort must be constant (do not hammer).

REMOUNTING
The mounting of the new bellows is to be
pe rform e d by m e a ns of t he PF 573 – 03
device.
Catch the inclined transmission in a vice
w ith soft jaws in ord er to avoid the sha ft
damaging. Engage t he PF 537 – 03 device over t he
tulip of the transmission shaft.
Obturate the small e xtremity of the bellows
and, abundantly grease with automatic
transmission oil or ELF CARDREXA RNT
2 grease: - the all outer surface of t he PF 537 – 01
device - the inner part of t he bellows, especially
its smaller diameter part (this operation is
performed for slipping help).

BRAKE CALIPER
DISMOUNTING
Lift the vehicle by means of a two columns
elevator.
Dismount the wheel.
Disconnect the wear sensor wire
Drain the brake fluid from the reservoir
Remove the locks and the caliper wedges;
Unscrew the rigid duct screw from the brake
flexible hose and detach the caliper assemb ly.
NOTE
If it is necessary to dismount the
caliper fork, unscrew the two attachment
s crews M 12.
When remounting the fork, replace the
Grower washers, tighten the screws at the
r equired moment of 6.5 daNm then seal
them with FIXAMED R 58. REPAIR
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 steel 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.
NOTE
Before remounting to t he wheel, c heck
the sealing of the caliper assembly.
