2.2 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.
