PASO 5 Selector assembly: Trapeze nut installation
Insert the M3n nut into the marked opening in the selector, just below the magnet.
Push it all the way in. Make sure the magnet doesn't get pushed out.
The easiest way of inserting the M3n nut is by an M3x30 screw used as a
handle.
Insert the M3nS nut into the marked opening on the other side of the selector.
Attach the trapeze nut onto the selector. There is a recess into which it should fit
nicely.
Fix the trapeze nut in place with two M3x10 screws. Tighten them just slightly for
now. We will tighten them up fully later on.
