DIFFERENTIAL
The differential of the
JH3-051 gearbox is the simple type (with two satellites and two planetary
wheels, one of which making a common body with the tulip of the planetary transmission).
This differential is supported in the clutch – differential crankcase by means of two cylindrical
bearings equipped with balls of various sizes.
The two bearings are pressed in the clutch – differential crankcase.
The crown of the main transmission is assembled by hooping, on the differential crankcase.
DIFFERENTIAL DISMOUNTING
This operation is to be performed after separating the crankcases.
The zero ring (1) is removed from the right planetary shaft, then by means of a pins extractor
and a hammer, the sealing gasket (2) is gently hit in order to make it pivoting.
The oil seal ring is carefully pulled along the grooved part of the planetary pinion in order not
to deteriorate t he grooves.

DISMOUNTIN G
Place the vehicle on a two-columns
elevator.
Dismount the right front wheel.
Drain the oil off the gearbox.
Dismou nt :
- the wheel protector
- the shock absorber attachment nuts
(1) on steering knuckle.
REMOUNTING
Lubricate with oil the new sealing gasket.
Mount the sealing gasket by means of the
C.V. 945 device.
M ount the protector (A) lubricated with
oil, on the planetary shaft and position the
gasket (C) by means of the device (B).
Rock the steering knuckle and disconnect
the planetary transmission from the gearbox.Remove
the “O” ring off the planetary shaft,
then, by means of a pins mandrel and a
hammer,
is gently hit in order to make it pivoting in its place.
Remove the sealing gasket by means of a
pliers, taking c are not t o damage the planetary
pinion grooves.

The right side
Due to t he solution assumed by the manufa cture r, the t ransmission j oint (the t ulip of the
transmission) with the t ransmission shaft of the gearbox shall be pe rformed only by m ea the
grooves.
The di smounting of the transmission, the side t o the gearbox, shall be pe rformed by a xial
displacement - extract the transmission tulip from the transmission shaft.
The left side
Drain the oil of the gearbox.
Dismou nt :
- the three screws for fixing the bellows – lid assembly on the gearbox;
- the transmission, the side to the gearbox.

REMOUNTING – THE SIDE TO THE GEARBOX
The left side
Engage the transmission GI joint in the gearbox (the transmission position as horizontally as
possible).
Mount the three attachment screws of the bellows l id on the gearbox.
The right side
Grease the tulip frame grooves (the grooves area) and the transmission shaft of the gearbox
with transmission oil.
Engage t he tra nsmission GI joint (t he tulip) on the transmission shaft of the ge arbox (the
transmission position must be as horizontally as possible).
REMOUNTING – THE SIDE TO THE WHEEL
For both sides
Engage the transmission in the steering knuckle, this one being necessary to freely enter, so that
threaded area of the steering knuckle is allowin g to remounting the transmission nut.
Perform then the dismounting operations in the reverse order.
Observe the tightening moments.
Remount the brake disk assembly.
Refill the gearbox with oil.
Press several times the brake pedal to enable caliper piston coming in contact with the brake
pads.
