2.17 Moving components and fastening supplementary units and equipment
If it is necessary to move units (various components, fuel tank, spare wheel, etc.) for the installation of particular equipment, the
operation is permitted on the condition that:
- the functionality of the units themselves is not jeopardised;
- the same type of original connect ion is restored;
- the new situation and distribution of mass is compatible w ith the original vehicle situation.
The protruding fastening of heavy components is not permitted (batteries, for example); the supports, in addition to being placed
on the side member, must be secu red to other components, such as support su rfaces or on e of th e sides.
Wheel holder
For cabs not supplied with a spare wheel holder, or if it is nec essary to move the location of t h e spare wheel, a suitable su pport
must be implemented that permits quick removal and that respects a minimum entry angle of 7˚.
Two possible solutions are shown in figures 2.31 and 2.32.
For the fastenin g of th e spare wheel on the side of th e vehicle with a support placed on the rib of the side member, it is recommended
to place a local reinforcement place inside or outside of the side member that is sized in function of the wheel weight and if there
are other reinforcements on the side memb er or not.

In order t o limit the torsional stress on th e vehicle chassis it is rec ommended to install it in correspondence of a cross member,
especially in the case of heavy units.
It is necessary to proceed in the same manner when installing tan ks, compressors etc.; t h eir location must be taken in t o account
when distributing weights (see Chapter 1.15). In all of these situations, a sufficient margin in their height from the ground must always
be guaranteed based on vehicle use.
