Place the tapered roller bearing (1) in the outer ring (2). Using
the keying device 99374134 (3) fit the gasket (under a press)
in the wheel hub.

Ensure the rest surface of screw heads is free from burrs, slags
or nicks before fitting new screws (3).
The load to be applied to screw heads for driving them into
their seats must not exceed 2300 Kg.
When driving operation is completed, screws should abut
perfectly on the wheel hub face : maximum squareness toler-
ance 0,2 mm.
If the oil slinger (2) was removed in order to be replaced, coat
oil slinger and hub mating face with sealing compound that can
resist heat to temperatures of 40 to 250

°C.

Fit taper roller bearing outer races in wheel hub using handle
99370007 (1) and drift (2): 99374094 for outer bearing race
(3) and 99374094 for inner bearing race.

When fitting race (3) do not use phonic wheel (1) as
a support base.
Press fit until bearings are 5 mm from abutting end and
then complete operation by hand.

Refit phonic wheel (2), if necessary, by heating to a tempera-
ture of 150

°C. Ensure phonic wheel is perfectly bedded onto

hub seat after installation.
Check squareness of phonic wheel (2) as follows.
Position wheel hub (4) with taper roller bearings on base of
column drill. Interpose a spacer between base and outer bear-
ing race (5) so that wheel hub may turn.
Rest a plate (7) on the internal bearing roller ring (3).
Turn handle (8) to raise base so that drill chuck comes into
contact with plate (7) and bearings (3 and 5) are slightly pre-
loaded.

Turn wheel hub to settle bearings when pre-loading.

Position magnetic base dial gauge with flat base stylus as shown
in figure and turn wheel hub. Check that maximum squareness
error for phonic wheel (2) does not exceed 0,2 mm.

ASSEMBLING WHEEL HUBS

Lubricate the bearing seat on the sleeve and the wheel hub
seal (1) with TUTELA W 140/M-DA oil.
Position the tapered roller bearing in the wheel hub (1) and,
using the tool 99345103 (2) applied as in the figure, fit the
wheel hub (1) onto the sleeve.

Tighten nut (1). Then adjust wheel hub bearing end play as fol-
lows.
Use wrench 99355167 (2) to tighten nut (1) to a torque of
98.1 Nm (10 kgm).

Fit the lock ring (2).
If the nut (1) for the locating dowel does not match any of the
lock ring holes (2) (see

→), progressively undo the adjusting

nut (1) until the lock ring can be inserted. (Consider also the
end play specification obtained with the previous operation).

Tighten nut (1) and torque it to 392.3 Nm (40

±2 kgm) using

wrench 99355167 (2).

Place a magnetic base dial gauge (1) on wheel hub (3); rest
gauge stylus on sleeve (2) and check wheel hub end play. It
should not be over 0.00

÷ 0.05 mm.

Fit the drum (1) onto the wheel hub (2).
Smear “Type B” sealing compound on both contact surfaces
between the drive shaft and the wheel hub.
Insert the drive shaft (4), screw down the screws (3) fixing the
drive shaft (4) to the hub (2) and tighten them, using a torque
wrench, to the prescribed torque.
Repeat this operation on the opposite side.
After these operations, replenish the axle housing with TUTE-
LA W 140/M-DA oil of the prescribed quantity and proceed
to check the transmitter for signalling differential locking works
properly.
Check the efficiency of the ABS sensors as described in the
“Fault-Diagnosis Guide” manual.

Apply tool 99395026 (1) to the wheel hub pins and, using a
torque wrench, check that the rolling torque is no greater than:
1.96 Nm (0.20 kgm).

This torque must correspond to a maximum end float of the
bearings of 0.05 mm.
