Modification of the wheelbase
2.4.8 Chassis reinforcements
Figure 2.7 shows some examples of solutions that can be implemented.
The reinforcements must be continuous and must involve the entire length of the vehicle chassis to the cab. For their connection
to the side member, in the case of an angular section, rivets or screws with a resistance class of 8.8 must be used; the diameter and
distribution must make it possible for the section to provide the foreseen contribution to resistance.
In the rear overhang area, and for about half of the wheelbase (in any case no less than 2 m from the front axle) it is recommended
to make a shear-resistant connection.
Bending stresses must be foreseen on the transformed chassis that are no greater than those on the chassis of the original vehicle,
in the corresponding sections.

To prevent consequences on the resistance of the original sections, it is not permitted to apply reinforcement plates directly on
the wings of the side members using holes filled with welding.
Alternatives may be authorised by IVECO only when demonstrated requirements exist, connected to the subsequent phase of
installing the superstructure.
In these cases, due to the deteriorationcaused by welding, it is a good idea to consider a reduction in material characteristics of
approx. 15%.
When sizing the reinforcements use the material suggested in Table 2.1 and the static stress values on the chassis specified in
Table 2.3 may not be exceeded.
In any case, comply with the most restrictive limits defined by national regulations.
2.4.9 Changes to the transmissions
To check the permitted changes, refer to chapter 2.8.
