Supplementary axles are not approved for use on the vehicle.
2.8 Modifying the Drive Line
Following the modification of the wheelbase, work on the transmission, as a general rule, is carried out on the basis of the
transmission of a similar vehicle with approximately the same wheelbase. The maximum value of the inclinations of the propeller
shafts used for standard production vehicles is to be retained. This rule must also be applied when any modifications to the suspension
and rear drive axle is made.
An all cases, contact IVECO and send them a diagram showing lengths and angles of the new proposed suspension for the necessary
authorisation.
The purpose of the specifications contained in this manual is to ensure the proper functioning of the transmission, to limit its noise
and to avoid the build-up of stress transmitted from the engine assembly. In no way does this diminish the responsibility of the
bodybuilder for the work he has completed.
2.8.1 Permitted lengths
The maximum operating lengths obtainable for both the intermediate shaft sections and the sliding shafts ”LG” or ”LZ” (see
Figure 2.8) can be determined according to the external diameter of the tube existing on the vehicle and the maximum operating
rotational speed (see formula). These are specified in Table 2.14.
For the propeller shaft length specified in Table 2.14. when the tube diameter is not sufficient, a new shaft section with the same
characteristics as the existing shafts must be used. As an alternative, in some cases transmission shaft with a larger diameter tube
can be used. The tube diameter required can be determined in compliance with the required length and the maximum rotational
speed, directly from Table 2.14.
