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 the grooves.

The stopping safety device (A) is extracted, by means of a pincers from the differential

crankcase (press on clutch crankcase in order to release the safety ring).

The differential assembly is dismounted using a press, by means of a bushing C.V. 554 (the

bushing is pressing on the differential crankcase).

Dismount the spacer washer (5) and the elastic concave washer (6).
The crown of the speedometer (8) is dismounted from the outside of the differential casing.

REMOUNTING THE DIFFERENTIAL

Remounting of the differential assembly is performed in the reverse order of the dismounting

operations, only this time the spacer that is mounted between the lateral surface of the crown
and the support bearing, shall be positioned with the concave side towards the crown.

DIFFERENTIAL BEARINGS REPLACEMENT

DISMOUNTING

In order to extract the big bearing (7), of the differential from the clutch-differential crankcase,

a profiled metallic strap is used, which is pressed by means of an extension, at a press.

In order to dismount the other bearing (10), first extract the safety (9), then press with a press

on the bearing by means of a sleeve with the outer diameter of 50 mm, towards the inside of the
clutch-differential crankcase.

REMOUNTING

In case of the bearing (7), its cage C must

be oriented towards the opposite side of the
differential crown.

In order to press this bearing into the clutch

crankcase, the C.V. 1059 device is used,
which is pressing on the outer ring of the bear-
ing.

When remounting the other bearing (10),

its cage C must be oriented towards the op-
posite side of the differential crown.

For pressing, the 65 mm diameter sleeve

of the C.V.1059 device is used, which is
pressed on the outer ring of the bearing

Remount the bearing maintaining safety.

MOUNTING

OF THE DIFFERENTIAL

ASSEMBL

Y IN THE CLUTCH CRANKCASE

The differential assembly is pressed into the crankcase, then the stopping safety device (3)

is mounted on the planetary shaft by means of the C.V. 946 device.

Rotate the differential assembly and check the speedometer pinion rotation.
Remounting of the (C) planetary oil seal ring is performed after this has been oiled, by means

of the CV 945 device and the (A) protector.

Mount the oiled protector (A), on the planetary pinion and position the oil seal (C) by means

of the (B) device.
