How do you open and remove a clevis from a control horn to adjust it after the linkage is on the aircraft?

I oen the clevis with a small screw driver. Insert between the legs and twist.

I grasp the control rod with small padded vise-grips and use a popsicle stick to turn the clevis (close clevise, insert short portion of stick and turn).

Just be careful when opening a plastic clevice with a screwdriver... (or knife) All too easy to damage the clevice pin. The metal clevices are better.

Note you NEED the 1/4 inch of fuel tube on any clevice to keep it locked on the control horn. If the load on the clevce is not 100% straight line down the pushrod, it can pop off if you don't have the piece of tube on it. (and the loads are NEVER perfectly straight down the rod.)

I gave up on everything but the (Great Planes?) metal clevises with the included spring clip retainers for the horn end, and the quick links with the STAINLESS STEEL socket head BOLTS (rather than those crummy set screws) at the servo. Adjustments are a snap, and I've never had one let go. The only place I'll use non-metalic clevises is at the throttle arm, though only if I'm out of ball links...

I have a neat little device called a "Clevis Tool". I have had it for years and don't know if it is still made, but it makes opening a clevis a stone cinch.

Is it the one by Sullivan? I am looking for a way to get the pin out of the clevis as well. Opening it, keeping it open and getting the pin out are always a fight. I was hoping someone makes something I am not aware of.

I just use my fingers. If I need to turn the clevis to make mechanical adjustments, I grip the end of the pushrod with unserrated pliers, and turn the clevis with my fingers.

I use a small screwdrive to open the clevis. Some metal clevises are really difficult to open though.

Dubro makes (made?) a small, red, plastic tool for turning the clevises. (I used to use my fingers too, but this thing makes it SO much easier, and cost about $0.79.)
