C.V. 949

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

of the C.V. 949 device and dismount the  3-4

C.V. 560

Dismount the attachment elastic pin of the re-

verse driving shaft, by means of the mandrel C.V.
560.

Dismount the secondary shaft assembly  to-

gether with the axle and 1-2 fork.

Place vertically the secondary shaft, with the

pinion of the 1-st gear downwards, so that  the
other pinions will not  fall down.

Recover the locking pins (A) and (B) of the

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.
