4.2 TIGHTENING TORQUES
The tightening torques specified in this section
are different from the standard tightening torques
cited in the overview of the standard tightening
torques. The other threaded connections not
specified must therefore be tightened to the
torque cited in the overview of standard
tightening torques.
When attachment bolts and nuts are replaced, it
is important that - unless stated otherwise - these
bolts and nuts are of exactly the same length and
property class as those removed.
