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.
