Replacing the wheel hub bearing
Figure 11
In case of a hub equipped with phonic wheel (4), remove the
latter by means of extractor made up of rear axle 99341003
(1), brackets 99341010 (2), and reaction axle 99341005 (3).
Otherwise, remove the bearing guard ring.

Take out the screws (2) and remove the brake disc (1) from
the wheel hub. Check the brake disc as described under the
Brakes heading.
The bearing (1) is removed from the wheel hub with the aid
of an ordinary punch.
Bearing (1) driving load is 2100
÷ 5000 kg.
NOTE

Mount the brake disc (1) on the wheel hub (2) and tighten
the fixing screws (3) to the required torque.
If it is necessary to replace the pins of the wheel hub (1),
before mounting the new ones, check that the mating surface
of the pin head is free from burrs, dross and blisters.
The pins should be driven in by applying a load on their head
no greater than 2000 kg.
After driving them home, check that the pins are perfectly in
touch with the hub: maximum orthogonal tolerance 0.2 mm.

Stand the bearing of the wheel hub (2) on a special mounting
that permits rotation. With a magnetic dial gauge (1) check
the off-centring of the brake disc on both sides.
Off-centring must not exceed 0.1 mm.
The phonic wheel (2) should be mounted in the hub with the
punch 99370498 (1), checking after assembly that the
”phonic” wheel rests perfectly in its seat in the hub.

Check the orthogonality of the phonic wheel (2), proceeding
as follows:
Position the feeler of the magnetic dial gauge (1) on the
phonic wheel.
Making the wheel hub (3) turn, check that the maximum
error of orthogonality of the phonic wheel (2) is no greater
than 0.1 mm.

Mount the inserter 99370497 (2) on the sleeve.
Lubricate the sleeve with TUTELA W140/M-DA oil and key
the wheel hub (1).
Check and, if necessary, adjust the clearance
between the parking brake drum and shoes as
described in the Brakes section.

Mount the washer (1) and a new ring nut (2). Using the
wrench 99355087 (3), tighten the ring nut (2) to the required
torque.
Notch the fixing ring nut (2) on the milling of the axle housing
arm.

Mount the support (2) and tighten the fixing screws (1) to
the required torque.

Mount the brake linings (1).
The brake lining with the wear indicator must be
mounted from the piston side of the brake caliper.
Fit brake caliper (3) to support (2), then use torque wrench (4)
to tighten fastening screws (1) to the torque of 32 to 36 Nm.
Having to move the brake caliper piston back, keep to the
instructions given in the BRAKES section.
Mount only new screws (1, Figure 24).
Every time they are removed, they must be
replaced.
NOTE
NOTE
Fit new protection caps (3).
Connect the pipe (2) to the support bracket (1).
Apply IVECO 1905685 sealant on the contact surfaces of the
drive shaft (2) with the wheel hub (1).
Mount the drive shaft (2) in the sleeve.
Tighten the screws (3) securing the drive shaft (2) to the hub
(1) to the required torque.
After the assembling operation has been completed, fill the
rear axle case with TUTELA W90/M - DA oil to the
prescribed amount and grade.

REPAIRING THE DIFFERENTIAL
Disassembling the differential unit
Figure 29
Extract the differential unit (1) from the axle housing.
Before repairing the differential it is necessary to
drain off the oil and dismantle the drive shafts, as
described under the heading of overhauling the
wheel hub (operation 525030).
NOTE
Note the assembly position of the adjustment rings
(2-4) of the spacers (3-5) and of the external rings
(6) of the tapered roller bearings to position them
for assembly in the same position.
In case of re-utilization, do not reverse the
assembling position of tapered-roller bearing
external rings (6).
NOTE

Use tool 99341003 (1), brackets 99341009 (2), clamp
99341015 (3) and reaction block 99345057 (4) to remove
taper roller bearing inner rings (5 - 7) from gear housing (6).
