Increase of tow weight
As regards tow vehicles, IVECO may evaluate - in certain cases and for particular applications - the possibility to authorise greater
tow weights than those normally allowed.
These authorisations include the towing conditions and, when necessary, provide the instructions relevant to any vehicle modifica-
tions or work required: standard crossbar reinforcements, or installation of a reinforced crossbar when available, or adjustments to
the braking system.
The drawbar coupling must be suited for the new use, and its connection flange must coincide with that of the crossbar.
Fix the crossbar to the chassis by using flanged head screws and nuts or hex head screws of 8.8 min. class.
Use anti-unscrewing systems.
Plates
Some countries require a plate to be applied on the towing device, which must list maximum tow load and maximum vertical load
allowed.
If not already mounted, the Outfitter shall see to its manufacture and installation.
2.7 ASSEMBLING AN ADDITIONAL AXLE
The installation of extra axles on the vehicle is not envisaged.
2.8 GEARBOX MODIFICATION
Gearbox adjustment, following wheelbase modification, must be done using the gearbox diagram of a similar range vehicle having
almost the same wheelbase.
The maximum tilt values of the drive shaft for the vehicle series must be respected, even for interventions on the rear engine axle
suspensions.
Contact the IVECO Technical Application for any difficulties; and send them a diagram with the length and tilt of the new transmis-
sion for a constant-velocity check.
The technical specifications in the gearbox Manufacturer manual must be used for correct production and installation of the sec-
tions.

Maximum allowed angularity
n = engine speed
β • n < 20.000 for classes 2040-2045-2050
β • n < 25.000 for classes 2025-2030-2035
Values that
​​
must be valid both when the vehicle is empty (tare only) and when the vehicle has a static load considering the max-
imum allowed load on the rear axle.
The scope of these instructions is to safeguard proper operation of the gearbox, limit sound level and avoid stress transmitted by
the drive assembly. In no way does this relieve the Outfitter of any work related liabilities.
