If the front wheels are aligned with the rear ones and the de-
tectors are balanced, push the wheel inclination button (3) and
the led (2) will be switched on. The digital indicator (1) will give
the value of the angle of inclination which must be 1

°.

Check upright angle of inclination (King Pin)
and clearance angle (Caster)

Check of wheel inclination (Camber)

Still having detectors perfectly balanced and the wheels com-
pletely aligned, use a lever (1) to move the lens cover.
Move the lever (2) and point the light signal index to the
ruler’s graph scale (3) corresponding to the rim’s diameter.
Repeat the same operations with the opposite detector and
read the toe-in values expressed in millimetres on the graph
scales.
The algebraic sum of the two detected values must amount
to: 0.5

÷ 1.5 mm with static load.

32981

Toe-in adjustment is performed by operating on
the track rod so that toe-in for each wheel is from
0 to 0.5 mm.

The wheels’ angle of inclination is a fixed value which
cannot be adjusted.
Therefore, if a different value is detected, remove
and dismantle the axle, make the appropriate inves-
tigations and possible replacements.

Still having the front wheels aligned with the rear ones, loose
knurled knobs (2) and set to zero the graduated sector (3)
on the swinging plate’s index (1).

32982

Turn the wheels inwards by 20

° and push twice the upright

inclination button (3), the led (2) will be switched on and nine
horizontal lines will appear on the digital indicator (1).

The upright angle of inclination and the clearance
angle are fixed values which cannot be adjusted.
Therefore, if different values are detected, remove
and dismantle the axle, make the appropriate in-
vestigations and possible replacements.

Turn the wheels outwards by 20

° and push again the upright

inclination button (2), the digital indicator (1) will display the
value of the upright angle of inclination (King Pin) which must
be 7

°.

32985

Without moving the wheel, push the clearance angle button
(3). The led will be switched on (1) and the digital indicator
(2) will display the value of the clearance angle (Caster) which
must be 3

°.

Figure 28

With the wheels in upright direction, set to zero the grad-
uated sectors (5) on the index (2) of the swinging plates (4).
If the steering angles which must be detected are bigger than
30

°, it is necessary to use as “0°” reference indexes the 20°

sign (1) placed on the swinging plate and the corresponding
one on the graduated sector.
Turn the inside wheel according to the prescribed value and
check that the outside wheel’s angle corresponds to the pre-
scribed value, considering that to make the survey it is necess-
ary to use as “0

°” reference indexes the 20° sign (3) placed

on the swinging plate and the corresponding one on the
graduated sector.
Repeat the same operations and check steering of the oppo-
site wheel.

DETACHMENT AND REATTACH-
MENT OF WHEEL HUBS

Detachment

Use a lifter to place and clamp the axle assy (1) on stand
99322215 (2) in order to make overhaul.

32990

Rotate wheel hub in order to set the screw plug (1) down;
unscrew plug and drain oil into a special container. Take off
the brake calipers.

Release the screws (2) and take off the brake callipers (1) from
the supporting flange (3).

Use torque lever 99370317 (4), to block wheel hub (2) rota-
tion and use wrench 99355038 (3) to unscrew oil cover (1).

Release the screw (1), unscrew adjusting ring (2) by using
wrench 99355038 (4) and remove the washer (3).

Screw tool 99370712 (3) on the steering knuckle pin. Use a
suitable rope (1) and a hydraulic hoist to support wheel hub
(2) with axle 99341003 (6) and its respective brackets
99341018 and reaction block (7), all of them applied as
shown in the figure, then take wheel hub (2) complete with
tapered-roller bearing inner race (5) and spacer (4) out of the
knuckle pin.

Remove the wheel hub as described in the related chapter.
Take off the sealing ring and remove the bearing’s inside ring
from the wheel hub.
Use the appropriate beater to remove the bearing’s outside
rings (1 and 2) from the wheel hub.
Check that the bearing’s outside ring housings on the wheel
hub are not burred as a result of the pull out operation.

Place the outside bearings’s outside ring (3) and use beater
99374093 (2) and handle 99370007 (1) to make setting.

Use general tools to remove the sealing ring (3) from the
wheel hub (5). Moisten with oil the new sealing ring’s inside
outline.
Use locking ring 99374457 (2) and handle 99370006 (1) to
place the sealing ring (3) on the wheel hub.
Replace the phonic wheel (if present).
Use general tools to remove the phonic wheel (4) from the
wheel hub (5).
Before setting the phonic wheel (4), warm it up to 150

°C.

Once the assembly is completed, check that the “phonic”
wheel (4) touches completely the wheel hub.
Check that the maximum orthogonality error of the phonic
wheel (4) is not higher than 0.2 mm.

Do not lay down the wheel hub on the phonic wheel
side, in order not to damage it.

Replacement of sealing ring

If present, do not use the phonic wheel as a support-
ing plane.
