Dismount the reverse driving contact (A).
In order to recover the balls and the lock-
ing springs of the 1-2 and 3-4 shafts, two
magnets placed in the C orifices are used.
Pull the control shaft towards exterior and
separate the crankcases
Dismount the reverse driving control shaft
and the 5-th gear.
Remove the pin of the 3-4 fork by means

SHAFTS
THE PRIMARY SHAFT
.
The primary shaft shall not be repaired and is not adjustable.
The shaft has a groove (B) for oiling the 5-th gear free pinion.
Clean the oiling – groove of the 5 th gear
The oil seal ring in front of the shaft and the bearing cams are in direct contact with the shaft.
Check the condition of the shaft surface in the operation area (A) of the oil seal; ring , and if
this shows ridges or irregularities, it will be replaced.
REPLACING THE BEARINGS OF THE PRIMARY SHAFT
The bearings of the primary shaft are freely mounted on it
There are two types of bearings:
- a cylindrical one with balls, pressed into the mechanism crankcase;
- a cylindrical one with rolls, pressed into the clutch-differential crankcase, together with
the clutch shaft oil seal ring.
The bearings replacement is to be done only with identical bearings with the original
ones.

BEARING
DISMOUNTING
OFF THE MECHANISMS
CRANKCASE
The safety ring of the bearing (the holding ring) is enlarged by means of a pair of safety pincers,
then the bearing is extracted from the crankcase by hammering towards the inside of the mecha-
nisms crankcase, by means of the C.V. 551 device.
BEARING
REMOUNTING OF THE MECHANISMS
CRANKCASE
Replace the safety of the bearings with a new one, then this one is introduced into its groove in
the mechanisms crankcase, so that its position is observed as compared to the crankcase (the
safety shows a shoulder).
The bearing is pressed from the exterior of the mechanisms crankcase towards the inside of it,
until the safety fits into the groove carved on the outer ring of the bearing.
Mounting of the bearing is performed by means of the C.V. 551 device.
