Operations on the suspensions
Changes to the rear suspension (vehicles with braking corrector)
A change to the rear suspension spring characteristics (e.g. no. of leaves, trigger loads, etc.) involves adjusting the braking corrector
regulation data. If the vehicle is equipped with ABS, regulation is not necessary.
When the work on the suspensions is due to substantial variations in the loads on the axles or variations in the overall vehicle weight,
it may be necessary to adjust the braking forces in order to comply with legal requirements. The necessary indications are included
in the authorisations issued by IVECO.
If instead the change in the rear spring characteristics does not involve variations in the load on the axles and in the overall weight,
the braking corrector calibration may be changed by an Authorised Workshop.
To avoid changing the vehicle’s braking capacity, the ”load on the ground/braking pressure” ratio indicated on the specific plate on
the corrector must be respected under the various load conditions.
To regulate this ratio, proceed as indicated in point 2.15.2, foreseeing a value corresponding to the rigidity characteristics of the new
spring for the load to be applied on hole 9.
If it is not possible to respect this ratio under all load conditions, contact IVECO for a new check of compliance with the legal
regulations.
If the data contained on the corrector plate is varied, then the plate must be replaced with another containing the new information.
Protection of the air springs
The body must have a dividing part that protects the air springs and that separates them from the wheels and prevents them
from being damaged by sand, mud or rocks.
The divider must leave a free space of 350 mm around the spring and must not block access for inspections and maintenance of
also the other suspension components.
