DRIVING TORQUE OF SCREWS, NUTS AND CONNECTORS
Before the disassembly of the various parts
and of the bolts and screws, read carefully
the instructions below.
To tighten the screws use the product LOCTITE 70 in
order to ensure the safety of the threaded couplings.
If it is not possible to loosen the screws because this
product is used, do not add extensions to the tools, but
heat the area (maximum 50°C) in oder to eliminate the
effect of LOCTITE 70.
In the above-mentioned cases use a small quantity of
LOCTITE 70 in the assembly phase (0% of the con-
nection surface).
The driving torque with which the threaded couplings
are tightened is very important to ensure the safety of
the truck connection.
The bolts and nuts and the corresponding driving torques
are shown in the tables on this page.
