Aileron pushrod

Wyzepilot · #1 03-23-2016, 11:43 AM

Good afternoon gentlemen,

I'm having difficulty inserting the threaded rod end into the aileron pushrod to match drill. It just too tight, and I haven't even primed it yet. Did anyone else experience the same thing and what's the best way to deal with it? I did debur the inside of the pushrod after I cut it and I'm sure that it's not getting caught up. Thanks!

Dave

I don't recall having any particular issues with this, but it's been a while. I'd just run a scotch brite pad inside the tube a bit to "open" it up and maybe squirt a tiny bit of some lubricant inside the tube and on the rod end.

Thanks so much for the quick replies. I just want to make sure that we are talking about the same part. It's the steel 1/2" diameter rod where a threaded end gets inserted. It's not the aluminum torque tube.

Yep , that was my understanding.

I had the same problem on a couple of the rod ends (not all).

With the help of a friend, we chucked the eye insert to a lathe and took off a minimal amount on the OD to perfectly match the ID of the rod.
This seemed like a better approach (at the time) since there was more meat on the bone of the eye insert.

I had the same problem on the RV-14 (same parts). On some of the ends, but not all I ended up with sandpaper on a dowel to smooth out the insides and even after that needed to use a hammer to gently encourage them in.

I purchased a steel rod that I could slide in the other side to tap out the piece for deburring.

I became very experienced at this of course, because I had to remake the part once after messing up the holes the first time around

You are supposed to prime the inside of the tubes. Don't lube them, the primer won't stick...

It's not a big deal. I'm talking about a little in the overlap area of rod end. It's easy to clean up and if it's a tight fit you'll have to remove any primer to get the rod end back in any way.

Quick update... I smoothed out the inside of the rod the best I could with a scotchbrite pad. Then I inserted the threaded end in my drill press and used that to lightly sand then scotchbrite till smoothe the end that is inserted into the rod. A very small amount of grease (which I will be sure to clean out before I prime) and several light taps of the hammer and presto it's in. Once again thank you guys for all of our help. I wouldn't be past the vertical stab if it wasn't for this web site.

Thanks for this thread, Dave.

Yesterday I was trying to get the threaded rods into the aileron pushrod and having a lot of trouble making them fit without having to pound them in with a rubber mallet.
I did run a sanding wheel on my dremel on the inside of the tube, and it started to help, but still can't get the rod ends in past the first hole.

Maybe I'll try some scotchbrite pad on the inside and keep at it until I can get them in there.
