Secure output shaft (2) with a rope, then lift it by about 20 mm
by means of a hoist so as to be able to move away countershaft
(1) and remove the motion inlet shaft (3) and the underlying
synchronizing ring and the roller bearing.
Turn rear half case (4) upside down.
Remove revs sensor (3).
Remove screws (2) and take off cover (1).
Remove phonic wheel (1), spacer (2) and ring (3) of roller
bearing.
Remove screws (1), take off cover (2) and remove spacer (3).
Remove the following items from rear half case (5): bushing
(4) supporting the fork supporting shaft, the tapered-roller
bearing outer race (1) and roller bearing outer race (2).
!
This operation must be performed with the greatest
care to prevent the ends of output shaft (2) and of
fork supporting shaft (4) from jamming in the relevant
bearing or support bushing.
Take output shaft (2) out of the rear half case, remove
fork supporting shaft (4) from the output shaft, then
place both shafts on a suitable container.
Remove countershaft (1).
!
When removing outer race (2), pay attention to the
possible escape of rollers (3) of the same from their
own seat.
Repeat the same operations on the front half case.

PARTS MAKING UP THE MOTION INLET SHAFT
1. Snap ring - 2. Spacer ring - 3. 4. 5. Cylindrical roller bearing - 6. Motion inlet shaft - 7. Matching body
Use ordinary tools to take the cylindrical roller bearing inner
race (5) and matching body (7) off the motion inlet shaft (6).
Assembling
Heat roller bearing inner race (5) to ~ 85
°C, then
fit it onto motion inlet shaft (6).
Apply LOCTITE 648 on inner teeth (
→) of matching
body (7), then mount the latter onto motion inlet
shaft (6).
Take 5
th
- 6
th
gear engagement sliding sleeve (2) off hub (1);
pay attention to the escape of rollers (3), pins (4) and springs
(5), then recover the same.
Remove snap ring (6).
OUTPUT SHAFT
Disassembling
!
All snap rings are provided with replacement parts of
different thickness in order to obtain correct
assembly play. Snap rings must be disassembled and
re-assembled with care so as not to score the output
shaft surface.
Prior to taking apart the output shaft, verify that the
axial play of every single gear falls within the
prescribed values.
Take note of the assembling position of synchronizers
- matching bodies, hubs and sliding sleeves, so as to
be able to fit them back in the same positions.

to remove reverse gear (5), shoulder ring (4) and roller
bearing inner race (3), then take out the roller bearing below.
