				Has anyone had their engine control cables get very, very tight?  I have the quadrant and the cables that came with it.  The throttle is OK but the mixture and prop are to the point that they take two hands to move.  Once the engine warms up (and the cables too, I assume), they feel fine.  They've gotten progressively worse over time.
   
 They were a little on the tight side when they were first installed, but manageable.  
 
 The stiffness is definitely in the cables, not in the fuel servo or the governor.  It's not in the quadrant pivot either.
   
 Also, the quadrant friction has always been more or less useless (but not exactly needed at this point).  Do other people actually use the friction knob?
 
 I guess I'll replace the cables and maybe order cables an inch or two longer.  Any suggestions?

				I've seen this with other control cables. Many times it is the lubricant getting old and hard. Check with your local motorcycle shop and tell them you want to an adapter for lubricating brake and throttle cables. It's a small device that clamps over one end of the cable while it is still in place so you can shot spray lubricate down the cable. When you use it be prepared for lubricate coming out the other end as it can be a mess if you are not ready for it.

 Dave,
 I have not had that problem but I did install cables a little longer then the stock cables.  I think the longer cables allows a little more give in the routing.

				I have seen it actually, if you have the cables with the plastic liner.  The liner will melt if the cable gets too close to a heat source.  Mine melted from the cabin heat dump washing over the cable as it exited the closed valve.  I was able to shorten the cable and liner and solve the problem.

				I had one cable that was a little long or sagged low enough enroute
 to my prop governor that it was within 3 or 4" of the heat muff.
 Ended up melting some of the outer sheath a little.  I ended up
 wrapping it in aluminum tape as a heat reflector and that has
 kept it holding up.  But I won't be surprised if that one gets
 sticky before the others.
 
 My quadrant though, going into the 4th year soon, has always been
 about perfect on tension. I don't really use the tensioner,
 it slides freely in warm or cold, and it doesn't back off
 and move un-commanded.  I had standard cable lengths, which
 although seemingly short, I was able to find good routings
 on and it's just always worked well.

				I believe the the T,M,P cables are Cablecraft cables. Try http://www.tuthill.com/us/en/brands/Cablecraft.cfm They  make the cables  for Cessna. You can order direct form  Cablecraft

 When I ordered by FF kit, I had them swap out 2 of my cables for longer ones.  Van's has several different lengths available and they can also custom order if what you want is not one of their stock lengths.

				Check your cables closely.  I have seen pictures on other sites where the inner cable unravels inside the sheath.  
 I am not sure if you can take the inner cable out to check this very easy but it is something you should consider.

  Gary , was that one of the green sheathed cables?  I'm kind of surprised it has a plastic liner but that would explain it.

 Has anyone had their engine control cables get very, very tight?  I have the quadrant and the cables that came with it.  The throttle is OK but the mixture and prop are to the point that they take two hands to move.  Once the engine warms up (and the cables too, I assume), they feel fine.  They've gotten progressively worse over time.     
 
  
  They were a little on the tight side when they were first installed, but manageable.  
  
  The stiffness is definitely in the cables, not in the fuel servo or the governor.  It's not in the quadrant pivot either.
  
  Also, the quadrant friction has always been more or less useless (but not exactly needed at this point).  Do other people actually use the friction knob?
  
  I guess I'll replace the cables and maybe order cables an inch or two longer.  Any suggestions?

				First, I agreeeee with all that Tim said... what I did was swap the cables around... and by doing so, I only had to replace one cable (the shortest one) with one that would now be the longest one.  So far all appear to be working perfectly.

 I had one cable that was a little long or sagged low enough enroute
 to my prop governor that it was within 3 or 4" of the heat muff.
 Ended up melting some of the outer sheath a little.  I ended up
 wrapping it in aluminum tape as a heat reflector and that has
 kept it holding up.  But I won't be surprised if that one gets
 sticky before the others.
 
 My quadrant though, going into the 4th year soon, has always been
 about perfect on tension. I don't really use the tensioner,
 it slides freely in warm or cold, and it doesn't back off
 and move un-commanded.  I had standard cable lengths, which
 although seemingly short, I was able to find good routings
 on and it's just always worked well.

				Dave, make sure you have a good ground between aircraft and engine, or check your ground and make sure it is not loose. Your cables could be making your ground and that would tighten them up eventually seizing them.

				Thanks to everyone who responded.  I installed new cables from a local Cablecraft distributor.  Changing them out wasn't as bad as I thought it would be.  I took the quadrant down from under the panel, disconnected everything at the engine, and basically yanked 'em out by the roots, still attached to the quadrant.  Then I rigged the new cables to the quadrant while it was out, and threaded the whole thing back through the firewall.  It took about half a day.
   
 I ordered a slightly different cable than the green ones supplied by Vans.  They look almost identical, with the coarse outer wrap, but they're black.  From what I can tell they're good for 310F vs. 230F for the green cables.  They feel nice and smooth.  I took a lot of time routing them in very gentle arcs and not clamping as tight as the last set.  Hopefully we'll get better service from these.
   
 I also added 1.5 inches to each overall length.  That made routing a bit easier.  I put a piece of firesleeve over the cables where they drop between the heat valves.  That's the only place I can see where it looks like they might get baked.
   
 Someone suggested lubricating the cables, which I've done on other aircraft and a few motorcycles.  But in researching this problem, I learned that Cablecraft cautions against trying to lube their cables as they are sealed at each end.  I guess that if you manage to get lube past the seal, you'll ruin it and possibly damage the cable.  The seals they're concerned about aren't the little rubber boots that slide off the ends.  They're inside the housing.
   
 BTW, the little rubber boots add a noticeable amount of friction, even when greased.
 
 I requested the complete data sheet on the new cables.  When I get it I'll post all the details, along with the exact lengths.
