Place countershaft (2) in rear half case (3). Lift the unit (1) thus
assembled. Apply tool SP. 2413 (4) to the output shaft end,
secure it by means of nut (5) and insert it into the rear half case.
While performing this operation, verify that the output shaft
is inserted into the support bearing, the internal driving shaft
is inserted into its respective bushing, and that the
countershaft can be matched with the output shaft.
Mount synchronizing ring (3) and roller bearing (2) on output
shaft (1).
Mount motion inlet shaft (2) by slightly lifting output shaft (5)
and opening out countershaft (1).
Remove the rope.
Place fork (4) pads (3) on sliding sleeve (7), then connect fork
(4) to selector (8) pin.
Force-fit tool SP. 2413 (6) onto motion inlet shaft (2).
Use beater 99374092 and handle 99370007 to mount the
countershaft tapered-roller bearing outer race (2) into front
half case (1), so that it is slightly embedded compared to half
case (1) outer plane by ~ 5 mm.
Mount cylindrical roller bearing (3) for the motion inlet shaft.

Apply LOCTITE 5900 on rear half case (3) mating surface,
then mount front half case (2). Remove tool SP. 2413 (1).
Fasten screws (7) and the screws with nuts (4) in the original
assembly position, then tighten them to the specified torque.
Mount a new seal ring (3) on pins (2).
Apply LOCTITE 5900 on the mounting flange of pins (2), then
insert the latter into the front half case so that they fit into the
5
th
- 6
th
speed engagement fork seats.
Fasten screws (1) with washers, then tighten them to the
specified torque.
Insert pin (5) with spring (4) into the front half case.
Mount small cover (2) with a new gasket (3). Fasten screws
(1) and tighten them to the specified torque.
Mount spacer (3) on cylindrical roller bearing (4), then secure
it to motion inlet shaft (1) by means of a new snap ring (2).
Use coupler 99370349 (2) and handle 99370007 (1) to fit a
new seal ring (3) to motion inlet shaft cover (4).

Apply LOCTITE 5900 on motion inlet shaft cover (1) mating
surface, then mount it on front half case (3).
Fasten screws (2) and tighten them to the specified torque.
Adjusting the axial play of countershaft
bearings
Mount adjusting ring (4) (of the greatest thickness among
those of the replacement parts supplied) on tapered-roller
bearing outer race (5), then mount spacer (3).
Loosen screws (1) and fasten them again so as to slightly lock
cover (2).
Use a thickness gauge (4) to measure, at four equidistant
points, the distance ’X’ between cover (2) and front half case
(3).
The thickness S of adjusting ring (4, Figure 93) is obtained as
follows:
S = A - X + P
where:
A = thickness of the adjusting ring used for measuring;
X = average value of measurements made;
P = bearing preload:
- new bearings
0.075
÷ 0.125 mm
- used bearings
0.00
÷ 0.05 mm
After measuring the thickness of the adjusting ring, remove
screws (1) and cover (2).
Choose an adjusting ring from among those supplied as spares,
of the calculated thickness, then mount it in place of the one
used for measuring.
Apply LOCTITE 5900 on cover (2) mating surface, then
mount the cover on half case (3). Apply LOCTITE 641 on
screw (1) threads, then fasten the screws with new safety
washers and tighten them to the specified torque.
Mount cover (2) on half case (6), fasten screws (1) without the
safety washers, tighten them evenly and, at the same time, turn
the motion inlet shaft in both directions of rotation in order
to correctly embed the bearings and feel some resistance
when rotating.
!
With the tapered-roller bearing embedded, spacer
(3) must jut out of half case (6) plane.

Turn the gearbox upside down. Remove screws (1), take off
cover (2) and remove tool SP. 2413 (3).
Take the seal ring off cover (3).
Use coupler 99374201 (1) to mount a new seal ring (2) into
cover (3).
Mount roller bearing ring (3), spacer (2) and phonic wheel (1).
Apply LOCTITE 5900 on cover (1) mating surface, then
mount the cover on rear half case (4).
Apply LOCTITE 641 on screw (2) threads, then fasten and
tighten the screws to the specified torque.
Mount revs sensor (3) and tighten it to the specified torque.
Lubricate the lip of seal ring (4) fitted into the rear cover.
Heat flange (3) to ~ 85
°C, fit it onto the output shaft, then
fasten locknut (1) onto the output shaft.
Stop rotation of flange (1) by means of tool 99370317 (2)
applied as shown in the figure.
Fasten nut (1) to the specified torque, then remove tool (2).
