Effects on braking
Generally speaking, shortening the wheelbase will have a negative effect on braking.
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) transformation 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"
(
➠
Page 9).
Additional information
●
Protect the surfaces against oxidation as in Paragraph "Added or modified parts" (
➠
Page 13).
●
Restore the braking and electrical systems as according to Chapters 2.15 (
➠
Page 49) and 5.7 (
➠
Page 36).
●
Follow the instructions in Chapter 2.8 (
➠
Page 37) for interventions on the transmission.
Checking chassis stress
With regard to wheelbase elongation, aside from local reinforcement in the joint area of the side members, the Bodybuilder must
also account for reinforcements - along the entire contour of the wheelbase - until achieving area strength modulus equal to
IVECO values for the same wheelbase or for the next admissible greater length. In alternative, for cases allowed by local standards,
larger counter-frame profiles can be adopted.
The Bodybuilder must make sure that the stress limits prescribed by national standards are respected. These stresses must not
be greater than those or the original wheelbase frame, assuming an evenly distributed load and considering the frame as a beam
positioned in place of the suspension supports.
When an elongation is performed starting from the longest original wheelbase, the reinforcements adopted must account for
wheelbase elongation, type of chassis produced and vehicle use.
