CHASSIS MODIFICATIONS 2-18 E URO C ARGO E URO 4 - 5 Modifying the Wheelbase 2.8 Modifying the Wheelbase 2.8.1 General Specifications As a rule, for each vehicle, modification to the wheelbase must be carried out on the standard wheelbase, above or closer to the new wheelbase required. The measurements given in the written authorization will apply in all cases particularly for extensions made to the longest standard wheelbase. On vehicles with a parallel chassis and constant-section side members, the wheelbase should be modified by repositioning the rear axle (or axles) when the internal reinforcements and their connections to the chassis permit it.
The suspension supports must also be repositioned ensuring that they are positioned where there are crossmembers in compliance with the points detailed in 2.3. In other cases the chassis may be cut following the instructions given in point 2.9. Whenever permitted by the body size, wheelbases should be made equal to those equal to those planned in our production. This enables the original transmission shafts and previously defined crossmember positions to be used. When extending a wheelbase beyond the planned production longest, the vehicle used must have the longest production wheelbase to ensure the correct thickness side members are used.
Particular care must be taken to comply with the limits set by national regulations particularly with regard to the limits for the overall dimensions (where specified). 2.8.2 Approval The alteration of the wheelbase is permitted without specific approval by IVECO in the following cases: - if the wheelbase is to be lengthened and the new value is still within the standard range of length with the same side member section and material as the original (see Table 2.8); - if the wheelbase is to be shortened without falling below the standard minimum values established for each model.
The chassis converter carrying out the operations must provide sufficient technological and quality control guarantees (qualified personnel, adequate operating procedures, etc.). Operations must be carried out in compliance with these directives, using suitable adjustments and adaptations when required, and taking all the necessary precautions (e.g. arrangement of exhaust pipes, respecting the minimum kerb weight on the rear axle, etc.), foreseen for the corresponding original wheelbases.
