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

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).

groove made on shaft, by means of a device type FACOM U 53 G, ( the flat side towards
bellows) in order t o avoid the defl ector damages on the wheel side. The pressing effort of the beari ng on the tra nsmission shaft ahas the value of = 100 –
700 daN. Press again the assembled tripod on the tra nsmission shaft observing the marks made
when depressing. The pre ss effort of t he tripod assembly on t he groove d area of t he shaft end, shall be
between 60 – 600 daN. Remount the blocking ring (Zeger lock) in the groove made on the tra nsmission shaft.
