Three drops of
LOCTITE FRENBLOC
are a pplied on the grooves of the fi xed pinion
for the 5 th gear, then this is m ounted by means
of the C.V. 1175 device on the secondary shaft.
Di smount the C.V. 1175 device and mount
the secondary shaft screw oiled with 3 drops of
LOCTITE FRENBLOC.
On the primary shaft remount the following
sequence :
- the support washers (with the larger side
towards the pinion )
- the bushing under the pinion;
- the free 5 th pinion equipped with its
synchroni ser ring ;
- the 5-th gear step hub equipped with its
spring after the hub grooves have been oiled with
LOCTITE FRENBLOC; - the fork together with the 5 th sliding
collar.
Engage the 1-st gear with the gear lever and
the 5 th ge ar by sliding the 5-th gear step fork
on its axle.
Apply 3 drops of LOCTITE FRENBLOC
on the primary shaft nut.
Mount the nut and the screw and tighten them
at the required moment: - primary shaft nut : 19 daNm
- secondary shaft screw : 7 daNm

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).
