Effects on braking
Generally speaking, shortening the wheelbase will have a negative effect on braking.
Table 2.10 indicates the wheelbase modification limits. Contact the IVECO Department - Homologation & Technical Application to
find out at what conditions (brake cylinders, minimum tare, theoretically admissible loads, tyres, height of centre of gravity) trans-
formation can be allowed.

The changes of the wheelbase on vehicles equipped with ASR necessarily lead to the updating of
the setting parameters of its control unit.
Intervention procedure
Proceed as follows to obtain good results:
●
position the vehicle so that the chassis is perfectly horizontal, use appropriate trestles;
●
detach the drive shafts, braking system hoses, cables and all other equipment that may interfere with proper work execution;
●
identify the reference points on the frame (e.g: guide holes, suspension supports);
●
mark the reference points with a slight punch mark on the top flaps on both side members, after having verified that the con-
junction line is at a perfect right angle with the longitudinal axle of the vehicle;
●
if moving the suspension supports, identify the new position using the previously determined references;
●
make sure that the new measurements are identical on both the right and left sides; the diagonal check, for lengths of at least
1500 mm must not yield deviations of over 2 mm;
●
make the new holes using as jig - if any other tools are unavailable - the supports and gusset plates of the crossbars;
●
secure the supports and crossbars using nails or screws; if using screws, bore the holes and use calibrated screws class 10.9
with anti-unscrewing nuts; if size allows, flanged head screws may be employed;
●
if cutting the frame (to be carried out according to indications of the second item in "Welding Operations" - Paragraph "Weld-
ing" (
➠
Page 9)) mark a second line of reference points so that the work area is set between the two lines (plan for a dis-
tance of at least 1500 mm upon work completed). Carry over the points relative to the cutting area between the two lines;
proceed as instructed in Paragraph "Welding" (
➠
Page 9);
●
before welding, check that the side members and any added parts are perfectly aligned and perform the check measure-
ments on both sides and along the diagonal line, as previously indicated. Apply the reinforcements as in Paragraph "Welding"
(
