Drilling the Chassis
The frame must not be drilled.
When auxiliary units or components are to be applied to the frame, existing factory-made holes must be used and the following
instructions must be applied.
Positioning and sizes
If it is necessary to make holes in the frame, it is compulsory to ask IVECO for authorisation.
2.3.1
Screws and nuts
In general, use connectors of the same type and class as those for similar fixings on the original vehicle (Table 2.7).
As a general rule, materials of class
8.8
are recommended. Class
8.8
and
10.9
screws must have been hardened and tempered. For
applications of diameter
±
6mm, stainless steel parts are recommended. Approved finishes are Dacromet and zinc coating, as detailed
in Table 2.2. A Dacromet finish is not recommended if the screws are to be subjected to welding. If space allows, use screws and
nuts with flanged heads. Use self-locking nuts. Nuts must be tightened using a torque wrench set to the correct torque setting for
the fixing.

2.3.2
Characteristics of the material to be used when modifying the chassis
When modifying the chassis of the vehicle, and in applications which reinforce the side members directly, the material used must
correspond in quality (Table 2.8) and thickness (Table 2.9) to that of the original chassis.
Should it not be possible to source materials of the thickness indicated, the next superior standard thickness may be used.
