2.5 Change of the rear overhang
2.5.1 General information
When changing the rear overhang, keep in mind the impact this has on the effects of the distribution of useful load on the axles,
with respect to the loads specified by IVECO (see chapter 1.15). It is necessary to comply with the limits specified by national
regulations as well as the maximum distances from the rear structure edge and the heights off the ground, defined for the towing
hook and the under-run protection. The distance from the chassis end to the rear edge of the superstructure must not normally
exceed 350
÷
400 mm.
If it is necessary to move the rear cross member fixed with screws, it is necessary to maintain the same type of standard connection
(number of screws, dimensions, resistance class).
If a towing hook is to be applied, sufficient distance (approx. 350 mm) must be left between the rear cross member and the nearest
one for possible hook assembly and disassembly operations.
If the work is done up to professional standards and in accordance with the instructions provided here, the originally defined towable
weight can remain unvaried.
The party who carries out the work is responsible for it.
2.5.2 Authorisation
The rear elongations of the chassis as well as shortening to a value shorter than what is foreseen standard for each model, if
implemented according to the instructions provided here, do not need to be specifically authorised.
For vehicles intended for special use, where load distribution is predefined and fixed, the rear overhang can be lengthened with values
greater than 60% of the wheelbase, providing that they comply with the conditions set forth in Paragraph 1.15.3, Directive EEC 97/27
and the relative national implementations with regard to the swing-out radius.
2.5.3 Shortening
When shortening the rear overhang of the chassis, the last cross member must be moved forward.
When the rear cross member results as being located too near to an existing one, the latter can be removed if it is not involved
with the suspension mounts.

For vehicles equipped with an ESP system, see paragraph 2.15.3.
2.5.4 Elongation
The possible solutions, based on the amount of elongation, are shown in Figures 2.8, 2.9 and 2.10.
Also a straight cut is permitted for the chassis. The minimum dimensions of the reinforcements to be applied to the area involved
with the change, are specified in Figure 2.3.
Figures 2.8 and 2.9 show the solution foreseen for elongations that do not exceed 300
÷
350 mm; in this case the reinforcement
angle bars, which also provide a connection between the cross member and the chassis, must have the same thickness and width
of the original connection plate. The connection between the cross member and plates, which was originally implemented using
rivets, can be done using 8.8 class screws with the next highest diameter, and nuts with loosening prevention systems.
