7.2 TIGHTENING TORQUES

The tightening torques specified in this paragraph 
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 - unless stated otherwise - that these 
bolts and nuts are of exactly the same length and 
property class as those removed.
