Iveco Daily Euro 4. Manual — part 166

Proceed as follows.

Measure external chassis width A

1

at the axle.

If chassis width is not 864 mm (reference value A), subtract
your reading (for example, A

1

= 859 mm) from the reference

value: 864 - 859 = 5 mm.

Divide this figure by 2 (5 : 2 = 2.5 mm).
2.5 mm is therefore the thickness of the compensating spacers
that should be fitted to each side member.

Spacers are supplied as spare parts in the following
thicknesses: 1 - 1.5 - 2 mm.

Calculating thickness of spacers to be fitted
between tie rod mountings and chassis side
members (with the exception of vehicles
equipped with 5-mm thick chassis or with
transverse leaf-spring suspension)

Project the light signal on the slide rule (1) and mark the value
shown.

Repeat the measure on the other wheel and check that the
value is equal to the noted down value, otherwise carefully
check the vehicle rear axle assembly

If no malfunctions are detected, check that the frame is not
deformed, sticking to the procedures described in the section
”Body and frame”.

Introduction

The external width of the chassis with reference to tie rod
mountings attachment point can vary from vehicle to vehicle
depending on chassis assembling tolerances and side member
thickness.
Therefore, width A (864 mm) is considered as an acceptable
reference value on which to base correct wheel geometry.
The above value results from the sum of chassis internal width
B (854

± 2 mm) plus thickness D

1

- D

2

of a 4 mm thick chassis.

Proceed as follows to install compensating spacers (1).

Dismantle:

- Rh and lh front engine guard (5 and 6).

- Engine oil sump guard (3).

- Rh and lh wheel guard (4 and 7).

- Rh and lh side engine guard (2 and 8).

Position spacers (1) of the thickness calculated before, fit
mounting (10), screw in screws (11) and lock them to a torque
of 14.25 kgm (142.5 Nm).

Reassemble all previously dismantled guards.

When assembly is completed, check and adjust wheel
geometry as required following directions provided in the
relevant chapters.
