Influence on braking
In general, shortening the wheelbase has a negative influence on braking characteristics.
Table 2.11 shows the limits for wheelbase modification. Check with the IVECO - Homologation & Technical Application department
about the conditions (brake cylinders, minimum tares, technically permissible weights, tyres, height of the centre of gravity) with
which these values are permitted.

In the case of vehicles equipped with an ASR system, the setting data must be updated.

Procedure
To obtain a good result, proceed as follows:
-
position the vehicle so that the chassis is perfectly flat, using suitable stands;
-
disconnect the propeller shafts, the brake system pipes, wiring and anything else that could prevent the work from being
performed correctly;
-
identify the reference points on the chassis (e.g. pilot holes, suspension mounts);
-
mark the reference points with a light punching line on the upper wings of both side members, after checking that the connecting
one is perfectly perpendicular to the vehicle’s longitudinal axis;
-
if moving the suspension mounts, identify the new position using the previously determined references;
-
check that the new dimensions are identical on the left and right sides; the diagonal check, for minimum lengths of 1500 mm,
must not detect deviations greater than 2 mm;
-
make the new drill holes using the mounts and cross member plates as a mask if other equipment is not available;
-
fasten the mounts and the cross members using rivets or screws; if screws are used, ream the holes and use calibrated screws,
class 10.9, with nuts with loosening prevention systems; if their dimensions permit it, flanged head screws and nuts can be used;
-
if cutting the chassis (to be carried out according to the instructions on page 2-11, point b) determine a second line of reference
points so that the area to be worked on is contained between these and the previous ones (ensure a minimum distance of 1500
mm after the operation is complete). Move the points relative to the cutting area inside the two lines of reference, proceeding
according to the instructions in paragraph 2.2.3;
