I realize that I am one of the lucky few to have the new horn, but I'll pose my question anyway. Has anyone installed the new horn yet? My shop (Clifton Aero) has run into an issue with the Loctite 668 getting hard before they can slide the horn into position on the tube.

If you have completed the install, I'd like to connect the fine folks at Clifton Aero with the shop that did the work. Feel free to email me through the forum.

Thanks in advance!

Hi Maurice,
I have installed the new horn on my Comanche and yes I had trouble with the Loctite setting too fast also. When you heat the horn as described the Loctite sets even faster. I had most trouble installing the balance arm into the horn and had to press it off once. No problems with installing the horn on the torque tube.

You only get 2 chances to heat it to 400*. I honed the horn to the allowable maximum fit and made a fixture to press balance arm into horn. Went together great. I had an old torque tube so I cut a piece off the width of the horn. Slide it in the horn then made a fixture from heavier metal, radius the same as tube on one side, flat on the top. Made a U saddle that would straddle the width of the horn, laid a heavy 1" square bar across my fixture inside the horn, setup the U saddle to mate with 1" bar. Careful align the bolts by sight. Please make sure you have the balance arm alignment correct Hopefully your technician marked top on the balance arm and the same with the torque tube.

I takes very little pressure to seat the balance arm in the horn. Apply the Loctite to the balance arm as you mate them. Again sight alignment of the holes is critical. As the holes begin to align begin to insert the supplied pin to make perfect alignment. The Loctite sets quick so toward the end of the push pressure was about 1000 PSI on my gauge.

Remove the tooling and your ready to slide the horn on the torque tube. That step went fairly easy.
