SECONDARY SHAFT ASSEMBLING
For G.B. 365 ºi 51C.
The differential drive pinion and the toothed crown are lapped together.
Replacing of one part obligatory requires replacing the pair part.
A pairing number is marked both on the pinion end and on the toothed crown.
No other markings shall be taken into consideration besides the pairing number.
NOTE: All spare parts will be lubricated with 80W 90 oil before bein
mounted.
Mount on the secondary shaft:
- the velocity step I pinion together
with its synchroniser ring ;
- the lock washer of the velocity step I
pinion ;
- a false wedge, made from a normal
wedge ,with a curved end ; the false wedge is
introduced in a channel which has a lubricating
hole.
Remove the maintaining device of the
bearing outer ring.
Mount the velocity steps I – II synchroniser hub:
- the three wedges ;
- the two springs ;
- the tooth gear sliding mechanism (for the re-used parts, observe the markings made upon
dismounting ).

The mounting of the hub I – II can be performed in two variants :
1.
By difference of temperature (for gearbox
made until 26.04.1999 , series 172321).
Place the velocity steps I – II synchroniser
hub on electrical stove , at a 120° C, dgr
temperature , and keep it there for about 15
minutes , to heat it.
2
. Without difference of temperature
( for gearbox made after 26.04.1999, series
172321).
The pressing force for the hubs I – II
and III – IV will be max. 2000 daN.
Press the assembled hub until it comes into
contact with the velocity step I pinion lock.
Center the three wedges in the synchronising
ring grooves.
Remove the false wedge.
Mount the hub I – II washer.
Mount the velocity step II pinion together with
its synchroniser ring.
Mount the velocity step II pinion washer.

Mount the velocity step III pinion and its
synchronising ring.
Mount :
- the velocity step III pinion lock washer;
- the lock wedge of the washers; the
wedge is mounted in a channel which has a
lubricating hole.
Mount on the velocity steps III – IV synchroniser hub :
- the three wedges ;
- the two springs ;
- the tooth gear sliding mechanism , with its groove opposite to the groove hub.
Press the assembled hub until it comes into
contact with the lock washer of the velocity step
III pinion ; the groove in the hub shall be oriented
towards the velocity step III pinion.
Centre the three wedges in the synchroniser
ring grooves.

Mount :
- the velocity step IV pinion and its
synchroniser ring;
- the adjustment washer for the conical
mechanism dist ance, recovered upon
dismounting;
- the biconical bearing;
- the spacer;
- the velocity step V pinion;
- the elastic washer.
Mount the speedometer endless screw (G.B.
365).
Mount the speedometer endless and flange
of the secondary shaft (G.B. 51 C).
Tighten the velocity step I, in a soft dies vice.
Engage gearbox in speed I.
Tighten at the required moment
(10-12 daN) the secondary shaft flange nut or
speedometer endless screw by means of the CV
204 wrench.
The speedometer endless screw shall not be
locked by straining in order to enable adjustment
of the conical distance.
Check the clearance (J) between the
synchronising rings of the velocity steps I and
II and the sides of the hub : J = min.0,2 mm.
The check shall be performed as follows:
- the pinion in contact with the hub;
- the synchronising ring in contact with the
pinion con.
Check in the same way also the clearance of
the synchroniser rings of the velocity step III and
IV.
