DISMOUNTING 

FROM THE CLUTCH – DIFFERENTIAL 

CRANKCASE

Dismount the clutch shaft bearing towards the clutch opposite direction, by means of the

C.V. 553 device.

Ensure that device is well fixed upon depressing the bearing.

BEARING 

REMOUNTING FROM THE CLUTCH – DIFFERENTIAL 

CRANKCASE

The remounting shall be performed using the same C.V. 553 device, the mounting direction of

the bearing being towards the clutch.

SECONDARY SHAFT

SECONDARY SHAFT DISMOUNTING

Dismounting of the secondary shaft is performed starting from the 4 th gear.
Dismount the elements, in the following order:

1. – the support washer
2. – gear IV pinion
3. – synchronizing ring;
4. – synchronizer for gears III and IV;
5. – stopping ring;
6. – grooved washer;
7. – synchronizing ring;
8. – pinion of gear III;
9. – grooved washer;

10. – stopping ring;

11. – grooved washer;

12. – gear pinion II;
13. – grooved washer;
14. – stopping ring ;
15. – synchronizer ring;
16. – synchronizer for gears I and II;
17. – synchronizing ring;
18. – gear I pinion.

The stopping rings are to be replaced after each dismounting.
For mounting and dismounting the stopping rings, a pair of safety pincers to keep the ends

apart, and, on the opposite side, a pair of flat tipped pincers to prevent the stopping ring
breaking, are  to be used.

                                             SECONDARY SHAFT REASSEMBLING

Before reassembling the secondary shaft, perform the parts checking, as follows:

- the pinions and claws tooth must not show chips or excessive wear;
- ensure that working surfaces of the shafts and the inner parts of the pinions do not show

traces of  gripping or abnormal wear.

When reassembling, clean the oiling grooves made in the secondary shaft and all its component

parts are to be pre – oiled.

Take into consideration that synchroniser hubs are matched with the slidings.
It is recommended to mark the positions of the sliding compared to the hubs.
The stopping rings are to be replaced after every dismounting.
Reassembling of the secondary shaft shall be done by performing the dismounting operations

in the reverse order.

REPLACEMENT OF THE SECONDARY SHAFT BEARINGS

The secondary shaft bearing from the mechanisms crankcase is  identical to the one from the

primary shaft so that its dismounting and remounting are performed in the same way as for the
primary shaft.

Bearing dismounting and mounting in the clutch crankcase is performed by means of the C.V.

522 device.

The bearing is set by means of a mandrel

(puncher) in four equidistant points on  a 55 mm
diameter.

X = 0,9 ÷ 1,3 mm.

NOTE:
When dismounting the bearing from the clutch-differential crankcase, the deflector

located behind the bearing will be damaged, being necessary its replacement with a
new one (this is ensuring the inside oiling of the secondary shaft).
