I have a new set of 1.25"x16 thread wheel pant axle nuts that I ordered from Aircraft Spruce (p/n 06-01677) in the wrong thread size, I need 1.25"x12. I will have to pay shipping to exchange them. If anyone wants them for $75 the shipping is paid.

I am thinking of making my own wheel pant mounts by slipping a tube inside the axle tube. Anyone done this before ? Stupid question, I am sure someone has. How are the inner tubes attached ? Using the cotter pin that goes through the nut and axle ?
Thank you

Yes, mine actually used a long clevis pin that took the place of the wheel nut cotterpin.

I just put an aluminum plug in the axle that protrudes out about 3/4". Held there with the cotter pin that is also securing the axle nut. A short AN4 bolt holds the outside of the wheel pant to the axle.

Most Pitts are aluminum plug. Factory installation calls for a shrink fit into axle and a drilled head AN3 bolt into a tapped hole in the plug. Cotter pin thru a hole drilled in the fiberglas, safety wire thru the cotter pin and bolt. I never used the cotter pin for safetieing the wheel pant bolt and never had one come loose with the bungee gear. Put the plug in the fridge and heat the gear a little and drive the plug in quickly with a plastic mallet.
Similar setup on my Tailwind but into an all metal lock nut. One side comes loose all the time. I am going to switch to a bolt and lock washer. If that doesn't work i'll go the extra cotter pin and safety wire. The left gear only on the Tailwind shakes violently some of the time at very low speed on landing roll. Home runway is poor asphalt so that is a factor.

The S1T uses a plug into the axle but its not a tight fit and wiggles a tiny bit. Never seemed to be a problem.
