How tight do you torque the bolts that hang the rudder pedals?

[ymc9]

I’ve had quite a few threads shown on the nutplate side and I feel I can keep going without an increasing friction. I suppose the nylon blocks are flexing to accommodate?

Should I try torquing it all the way to the standard AN3 torque value? I’m wondering if it’ll affect the mobility of the pedals.

No
The UHMW blocks are compressible
The bolts should only be tightened enough to bring all the parts together and then about an additional quarter turn to put a little bit of tension on the bolt.
This will allow you to meet the KAI statement that the rudder pedal assemblies, moving freely.

I would torque to AN-3 values.

The washer between the 2 blocks is your spacer for movement.

But it says to check that after assembly.

Actually, the washer is to reestablish the proper dimension after sawing the blocks in half.
The block itself is very compressible.
If you use a torque wrench and torque to the standard AN3 bolt torque, you can watch the washer compress into the block as you turn and turn and turn.
This compression is definitely changing the overall dimension of the hole that the tube rotates in.
