Working procedure

:

Temporarily mount the inner ring with balls of the back bearing on the pinion, and introduce

it in the casing , without mounting the adjustment washer.

Tighten the flange nut at a moment of 3 – 4 daNm.
Set the comparator dial to zero.

1. ADJUSTMENT OF THE CONICAL DISTANCE

Now set the 18 mm spacer C in front of the differential drive pinion and the chuck M, in the

half casings of the bearings.

By means of the comparator dial , measure the difference between the real value (the mea-

sured one) and the value A.

Depending on the value of this difference, select the washer of the required thickness.
The washer shall be placed under the outer ring of the big bearing.

2. ADJUSTMENT OF THE DRIVE PINION BEARINGS

The drive pinion is mounted in the casing together with the two bearings, without the adjustment

washer.

Mount the cardanic flange and tighten the nut at a moment of about 0,20 daNm, so that the

pinion rotates easily at a load between 2 and 3 daNm.

Mount the support S of the comparator dial CC on the cardanic flange.
Remove the support and the dial, dismounting the flange and the inner balls ring of the bearing.
Remove the differential drive pinion from the casing, clamp it in a vice and place on its shaft

the following parts :

- the front bearing washer;
- the bearing inner ring;
- the flange;
- the nut.

Tighten the nut at a 9 – 11 daNm moment and place the support with the comparator dial

again on the flange, measuring the difference between the axis and the differential drive pinion
front side. The value of this difference corresponds to the value of the
adjustment washer thickness.

Dismount the followings from the pinion: the flange ,the bearing inner ring and washer.

Remove the pinion from the vice, place it again in the differential casing., mounting the following

parts on the pinion shaft : the adjustment washer, having the thickness
previously established, the bearing washer , the balls inner ring, the annular oil seal , the flange
and the nut, which shall be tightened at a moment of 9 – 11 daNm.

3. ADJUSTMENT OF THE DIFFERENTIAL DRIVE PINION AND

DIFFERENTIAL RIM CLEARANCE

In a first phase, the clearance of the conical group gearing is measured by hand.
The checking and the exact correction are performed using the comparator dial.

Working procedure:

Place the differential drive pinion, the rim –

casing assembly, the bearings set, the
adjustment nuts in the differential casing,
observing the marking make upon dismounting.

Tighten the bearings casings screws at a mo-

ment of 4 – 5 daNm;

Screw the adjustment nuts until the gear clear-

ance may be estimated by hand.

Mount the comparator dial with the sensor

perpendicular on the rim tooth flank and check
the clearance of the gearing: it should be
between 0,12 and 0,25 mm.

The measurement shall be performed in three equidistant points.
The correction of the clearance shall be performed by means of the adjustment nuts.

The differential bearings clearance is correct if, upon rotating the differential, a
0,05 – 0,20 daNm moment is used.

After performing the a.m. adjustments, lock the adjustment nuts by means of the plate retain-

ers.

Remount the sleeves and the pins, observing the marks made upon dismounting.
