2-40 CHASSIS MODIFICATIONS E UROCARGO Euro 4/5 Figure 2.16 91461 1. Bracket - 2. Plate - 3. Screws, rivets or Ш 20 to 30 mm holes to be filled with welding Where an auxiliary frame is required as reinforcement (see point 3.1), the body mounting brackets on the chassis (if any) should be used for the attachment. An alternative method of attachment is shown in point 3.1.2 and those that follow it. We recommend using shear resistant connection in the area of the rear overhang up to approximately the mid wheelbase (or to a point no closer than 2 m from the front axle) (see Figure 2.16).
The fitting of reinforcing plates directly onto the flanges of the side members, using holes filled with welded material is not permitted. This is to avoid affecting the strength of the original sections caused by poor welding. This procedure is only permitted in special cases with specific IVECO authorization when there are proven difficulties in subsequent body applications. It is possible to do without reinforcements on the frame if the static stress values in the Table 2.9 are not exceeded. Any limitations, imposed by national regulations must be complied with.
Because of the deterioration of the material’s properties during the welding process, if the installation is unavoidable it is then advis- able to assume a reduction of 15% in the strength of the material when checking the load-effects acting on the various sections of the chassis. As a general rule the thickness of the reinforcing plate must not exceed that of the flange of the original chassis. The mounting must be carried out by skilled personnel and the bodybuilder will be responsible for any damage to the frame resulting from poor workmanship.
