Subject: LNC2 Rudder System Friction

LNC2 Gang,

I just connected the rudder cables on my 320 last night and was quite dismayed 
at the amount of friction in the system.

First, a little background.  I have the adjustable rudder pedal option with 
pedals installed only on the pilot side.  The rudder hinging itself has 
virtually zero friction.  The cables were installed per the instruction manual 
(nylaflow tubing) and I used the teflon powder as recommended on the LML a 
couple years ago.  Prior to bringing the pedals into the system, one could 
push and pull the cable in the footwell and make the rudder move with almost 
zero friction -- I was quite proud of myself.

Now, with the pedals connected, there is so much friction that I doubt the 
rudder will return completely to its zero point with air loads.  My thinking 
is that the spring force in the two pedals -- pushing them both forward -- is 
what is causing the binding.

How much spring force is necessary or desired on the pedals?  Mine seem to be 
quite excessive -- without the cables connected they SLAM themselves forward.  
I wonder if the coil spring is wound one too many turns tight.

Any help is greatly appreciated.


Thanks!
