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 t ransmission shaft of the gearbox shall be pe rformed only by m ea the
grooves.
The di smounting of the transmission, the side t o the gearbox, shall be pe rformed by a xial
displacement - extract the transmission tulip from the transmission shaft.
The left side
Drain the oil of the gearbox.
Dismou nt :
- the three screws for fixing the bellows – lid assembly on the gearbox;
- the transmission, the side to the gearbox.

REMOUNTING – THE SIDE TO THE GEARBOX
The left side
Engage the transmission GI joint in the gearbox (the transmission position as horizontally as
possible).
Mount the three attachment screws of the bellows l id on the gearbox.
The right side
Grease the tulip frame grooves (the grooves area) and the transmission shaft of the gearbox
with transmission oil.
Engage t he tra nsmission GI joint (t he tulip) on the transmission shaft of the ge arbox (the
transmission 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 allowin g to remounting the transmission nut.
Perform then the dismounting operations in the reverse order.
Observe the tightening moments.
Remount the brake disk assembly.
Refill the gearbox with oil.
Press several times the brake pedal to enable caliper piston coming in contact with the brake
pads.

Using a press, extract the assembled tripod,
sustained it on an extractor, FACOM U 53 G
type, protecting the tripod clogs.
Before extracting, mark the position of the
tripod compared to the transmission shaft end.
Dismount the bellows - deflector bearing in
the same manner like tripod dismounting .
REMOU NT I NG
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
backside 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.
IMP ORTANT:
In order to avoid the deformation of the bearing, which includes a sealing gasket
(annular oil seal), the pressing effort must be constant (do not hammer).

Maintaining the transmission on the press, on both sides, shall be ensured on the G groove
made on shaft, by means of a device t ype FACOM U 53 G, ( the flat side towards bellows) in
order to avoid the deflector damages on the wheel side. The pressing effort of the bearing on the transmission shaft ahas the value of = 100 – 700
daN. Press again the assembled tripod on the transmission shaft observing the marks made when
depressing. The press effort of the tripod assembly on the grooved area of the shaft end, shall be between
60 – 600 daN. Remount the blocking ring (Zeger lock) in the groove made on the transmiss ion shaft.
