2.3 Drilling the Chassis
The frame must not be drilled.
When auxiliary units or c o mponents are to be applied to t he frame, existing factory-made holes must be used and the following
instruct ions 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
app lications of diam eter
± 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 fla nge d head s. Use self-locking nuts. Nuts must be tightene d using a torque wrench set to the corre ct torque setting for
the fixing.

2.3.2 Characteristics of the material to be used when modifying the chassis
Whe n modi fyi ng the chassis of the vehicle, and in ap p l ica tio ns which reinf or ce the sid e members dir ectl y, the mater i al 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.
