4.2 TIGHTENING TORQUES

The tightening torques stated in this section are 

different from the standard tightening torques 

stated in the overview of the standard tightening 

torques. The other threaded connections not 

specified must therefore be tightened to the 

torque stated 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.
