The following table indicates the standard driving torques
for screws and bolts with metric ISO thread.
For specific joints or couplings of the vehicle, see 2.41
(FASTENING ELEMENTS).
If not specified otherwise, the indicated driving torques
are valid for clean and dry threads, at room temperature.
NOTE
In order to avoid any deformation and/or imper-
fect coupling, tighten the screws or bolts by proceeding as
described below:
◆ Manually screw all the fastening elements.
◆
Applying half the prescribed driving torque, tighten the
elements that are diametrically opposite each other: (A)
and (B); (C) and (D).
◆
Repeat the previous operation by applying the pre-
scribed driving torque.
NOTE
In this way the pressure exerted by the fastening
elements will be uniformly distributed on the joint surface.
