Question about bushing for the elevator pushrod Kitfox III

[t j]

Here's a picture of my belly. I installed an inspection hole ring about 6 inches behind the bushing when I covered so I could get in there to clean and regrease it at annual time. One handed didn't work too well so I put another ring on 6 inches in front later for two hands to get in there.

On my model-4, my elevator push rod can be removed with the stock bushing in place. You See, when I built the push rod, I special ordered some exact length pop rivets so that the push rod ends would be riveted on with almost flush rivets (the ones they give you are too long and stick up). Works great.
hope this helps

Your bushing is there. I think if the tube won't slide something else somewhere in the linkage is restricting it.

It looks like yours needs to be cleaned up and re greased. I can Wrap a kitchen paper towel around the tube and hold on to it and slide the tube back and forth with the towel going through the bushing to wipe the old grease out then put new grease on the tube at each condition inspection.

The bushing on my model 2 has come loose from the bracket it is attached to on the fuselage and is now just on the elevator push rod. I was able to easily slide it back in place, but it quickly worked itself back out. Does anyone know whether it is supposed to be glued into place? I haven't found how the bushing is actually kept in place on the bracket in the fuselage. Any help would be great.

I have owned two Model IVs and in the time I have had them - about 12 years there was one time I needed to get the press fit bushing out for a maintenance issue. My first impression would be to score the outside of the bushing to give a roughness that would help a structural epoxy fasten it in place. Then remembering the need to remove the bushing that one time in order to remove the push rod, my thinking now would be to drill through the steel housing and partially into the bushing, then fabricate a short pin that would secure the two together and hold it in place with a circle clamp.

Thanks very much for the info Highwing. So the bushing was originally simply pressed in and wasn't retained in any form other than friction? Perhaps I need to press it back in with a bit more effort and lubricate the push rod. My plane has an access hole under and to the slight aft of the push rod, so I can gain access for this.

Maybe I will try pressing it in a little further and lubricate with it boeshield t-9 and monitor it.
