If the hub is fitted with a phonic wheel (2), take it out with
the extractor (1) 99341001 as shown in the figure.
Otherwise, take out the bearing guard ring.
Take out the screws (
⇒) 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.
Mount the brake disc (1) on the wheel hub (2) and tighten
the fixing screws (
⇒) 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.

The new bearing should be mounted in the wheel hub with
a press and tool 99370498.

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.
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).
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.
Figure 21
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.

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.
Fit new protection caps (3).
Connect the pipe (2) to the support bracket (1).

Mount the support (2) and tighten the fixing screws (1) to
the required torque.
Mount braking pads (1).
Fit brake caliper (3) to support (2), then use torque wrench
(4) to tighten fastening screws (1) to a torque of 32 to 36
Nm.
!
Braking pad with wear signalling unit must be
mounted at brake caliper plunger side.
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.
