To avoid affecting the resistance of the original sections, reinforcement plates may not be mounted directly onto the side member
wings via holes filled with welding material.
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 7)".
In any case, any more restrictive limits imposed by national standards will be valid.
2.4.9 Modifications to the transmissions
See Chapter 2.8 for checks of modifications allowed.
2.5 REAR OVERHANG MODIFICATION
2.5.1 General information
When modifying the rear overhang it is necessary to note the variations that this modification shall inflict on the payload distribution
on the axles, in compliance with the loads established by IVECO (see Chapter 1.15 ). Limits set by national law must also be respec-
ted, as well as maximum distances from the rear structural edge and distance 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.
Also observe the indications relating to vehicle mass (see Chapter 1.15 - Paragraph "Observance of the permitted masses" )
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.
