Only when there is a proven necessity associated with subsequent superstructure installation stages may IVECO issue an excep-
tional authorisation.
In these cases, because of the deterioration caused by welding, a reduction of the characteristics of the material of about 15%
should be borne in mind.
When calculating the dimensions of the reinforcements, use the material suggested in Table 2.1 and do not exceed the static stress
values on the chassis given in the Paragraph "Stresses on the chassis (
➠
Page 8)".
In any case, any more restrictive limits imposed by national standards shall be valid.
Gearbox modifications
See Chapter 2.8 (
➠
Page 26) for checks of modifications allowed.
2.5 REAR OVERHANG MODIFICATION
General information
When modifying the rear overhang it is necessary to take note of the variations that this modification inflicts on distribution of
axle loads, in compliance with loads established by IVECO (see Chapter 1.15 (
➠
Page 11)). Limits set by national law must also
be respected, as well as maximum distances from the rear structural edge and heights from ground, defined for towing hook and
under-run protection. The distance from the tip of the frame to the rear edge of the superstructure must, as a rule, not exceed
350 ÷ 400 mm.
If it is necessary to move the rear crossbar fixed using screws, it is necessary to maintain the same type of union as in the series
(number of screws, dimensions, strength class).
If a drawbar shall be attached, it is necessary to leave sufficient space (approx. 350 mm) between the rear crossbar and that
nearest, for any drawbar assembly/disassembly operations.
If all works are performed in a professional manner and according to the instructions contained herein, the original towing capacity
may remain the same.
In all cases, the parties performing the work shall be liable thereof.
Authorisation
Rear frame elongation as well as shortening to the smallest value for each model of the series do not require authorisation if per-
formed in compliance with the instructions provided herein.
For vehicles destined to special uses, where load distribution is predefined and fixed, the rear overhand can be extended with val-
ues greater than 60% of the wheelbase, as long as the conditions stated in Chapter 1.15 (
➠
Page 11), Directive CEE 97/27 and
their relative national laws are respected in terms of cornering path.
▶
If you need to adjust the length of the electrical circuits, see Section 5, "Special instructions for
electronic subsystems”.
Chassis Shortening
The last crossbar must be moved forward when shortening the rear overhang of the frame.
When the rear crossbar is too close to another crossbar, the latter can be eliminated if it plays no role in suspension support.
▶
For vehicles equipped with the ESP system, see Chapter 2.15 - Paragraph "Derating of the ESP
system".
