Okay, if this has been posted or is in the FSM or Haynes then point me to it please but I can't find it in any of the three.

The aux. port actuators have little adjustable screws with pointy ends and lock nuts that clearly adjust something? I am assuming they vary the spring preload to either change the pressure required to acutate or the time to close (or both)? Does anyone know? If so, which direction accomplishes what?

It would seem that this adjustment would allow one to vary the RPM at which the ports actuate.

 

I never gotten a chance to inspect it properly but would love to see what you are refferring too. Anyone got pics, i love pics!

 

I'm travelling this week but I can post pics on Friday. Basically if you reach under your actuators you will feel a phillips head screw sticking out of the center of the bottom. There is a little nut where it threads into the actuator that locks it once you set it. Again, I've never seen any reference to it in the FSM, this site or the Haynes?

 

i've messed with s4 actuators a lot... the screws don't appear to do anything useful.
