Lubricate the sleeve and the sealing ring supporting ring (1)
with TUTELA W140/M-DA (SAE 85W140) oil.

Use suitable rope and hoist to fit wheel hub (1) on sleeve (4).
Lubricate spacer (2) and outer bearing inner ring (3) with
Tutela W140/M-DA and fit them on sleeve (4).

Lubricate rear taper roller bearing inner ring (4) with SAE W
140 M-DA oil and fit it to wheel hub (5).
Use tool 99374132 (2) provided with proper handle
99370006 (1) to fit sealing ring (3).

Fit the brake disc (3) on the wheel hub (1) and tighten the
fastening screws (2) to the specified torque.

Fit the phonic wheel, if any, on the wheel hub.

Use tool 99374132 (2) side to position the sealing
ring (3) at 1.5 mm from wheel hub side surface.

NOTE

Phonic wheel fitting shall be performed after heating
it at 150ºC.

When fitting is over, check whether the phonic
wheel is resting perfectly on the hub seat.

Check whether phonic wheel squareness and
oscillation is lower than 0.2 mm.

NOTE

Check and, if necessary, adjust the clearance
between the parking brake drum and shoes as
described in the Brakes section.

Fit the safety washer (3) so that the clip is guided properly into
rear axle casing sleeve groove.
Tighten ring nut (4) with wrench 99357080 (1) and
dynamometric wrench (2), tighten the new ring nut (4) to the
specified torque.

Position the dial gauge 99395684 (1) with a magnetic base
on the wheel hub (3) and rest the rod on the sleeve (2).

Check whether wheel hub end play is falling between 0 and
0.16 mm.

Use tool 99395026 (2) and the dynamometric wrench
99389819 (1) to check whether the wheel hub rolling torque
is falling between 0 and 4 Nm (0 - 0.4 kgm).

After checking the end play and the rolling torque, check
whether one of the adjustment nut (1) holes is coinciding with
one of the safety washer holes otherwise loosen the
adjustment nut (1) until it is possible to fit the fastening screw
(2). Tighten the fastening screw (2) and the adjustment nut to
the specified torque.

Smear the contact surface between axle shaft (3) and wheel
hub (1) with IVECO sealing compound 1905685.
Fit axle shaft (3), tighten the fastening screws (2), excluding
those set between the two wheel hub marks (see Figure 30)
with tool 99370317 (4) lock wheel hub (1) rotation.

Set horizontally to ground the two holes (1) located between
