The internal control axles must not show any deformations or wear on the milling for locking
balls, and their sliding on bearings must be done freely, without excessive clearance.
The contact surfaces of the forks with collar of the rocking must not show either deformations
nor wear.
Ensuring of the control forks axles is performed by means of the balls and springs placed in
the holes made in the mechanisms crankcase.
The locking of the control axles is done by means of some cylindrical rolls mounted inside
the clutch–differential crankcase.

CONTROL
AXLE DISMOUNTING
This operation is to be performed after crank-
cases separation.
The control axle is provided with a blocking
element “LOCTOU” –(A) attached on the
crankcase.
The sealing is ensured by means of the tore
gasket (B).
Remove the elastic pin of the selection lever
(C), then dismount the attachment screws, and
retrieve the control axle assembly.
In order to replace the bearing bushing of the control axle, the CV 1162 device, or a tube with
the outer diameter 16.5 mm are to be used. Before mounting the bushing shall be oiled.
CONTROL AXLE REMOUNTING
When remounting the control axle, replace the selection finger pin with a new one.
Remounting is done by performing the dismounting operations in the reverse order, after all
parts have been oiled with oil.
Tighten all attachment screws of the control axle assembly at the required moment of
2 daNm.

CRANKCASES ASSEMBLING

The assembling surfaces must be flat (small
imperfections can be eliminated by means of
a thin file).
Place the axle and 1-2 fork, assembled,
on the 1-2 sliding collar of the secondary shaft.
The two shafts (primary and secondary)
are taken together with the fork and 1-2 axle
and positioned at the same time into the clutch
– differential crankcase.
The crown and the secondary shaft are
rotated until the end of the secondary shaft
fits into the bearing.
Mount the blocking roll of the shaft ˚ (A).
With the 1 – 2 axle in free position, the fol-
lowing are mounted:
- synchronizing assembly 3 – 4 together
with the axle and the 3 – 4 fork;
- mount the pin of the fork 3 – 4 by means
of the CV 949 device.
Mount the blocking roll of the 5 th gear axle
(B).
After that, mount the followings:
- the control axle for the 5 –th gear and
reverse driving (A);
- the axle and the reverse driving pinion
assembly (B), by easy lifting the primary shaft.

Mount the elastic pin for reverse driving axle
attachment by means of the C.V. 560 mandrel.
Ensure the correct positioning of the two cen-
tering bushings and of the magnet.
Mount the springs and the locking balls 1-2
and 3-4 in the mechanisms crankcase, then the
false axes A with a 13-mm diameter are intro-
duced.
Check the positioning of the 5 th gear oiling
collector and of the aerating connection.
Additionally, ensure (check) if the aerating tube
is not damaged or clogged.
Apply a continuos layer of LOCTITE
518 on the gasket surface between the clutch
crankcase and the mechanism crankcase.
Engage the 3 -d gear.
Mount the spring and the 5 th gear lock-
ing ball into the crankcase of the mechanism.
Compress the locking ball and mount the
mechanisms crankcase.
Mount the attachment screws and tighten
them at the required moment of 2,5 daNm ,
after rotating the primary shaft, in order to
ensure o correct bearings setting.
Retrieve the false axes.
REMARK :
The tightening at the required mo-
ment of all the screws must be done in
no more than 30 minutes after the
mounting of the mechanisms crankcase,
because of the polymerization of
LOCTITE 518.
