I have a question that can't be answered by the parts book or any S-2 assembly drawings I have;
The upper arms on my airplane have a KSP3L on the right side and a K3L (not KP3L) on the left side. I noticed there was some rotational freedom on the right side slave strut and none on the left side. I figured it might be a bearing going bad but most likely it was a different bearing on that side because there was no free play in the ailerons. That turned out to be the case.
I know it doesn't really matter for the round slaves and maybe the factory was just using a cheapest option or the best 'in stock' option. Or maybe that bearing was replaced and the wrong one was used?? If/when I put streamline slaves on the airplane that bearing will have to be replaced anyway so I'm doing it now.
So, does anyone know if it is common to see a spherical bearing in the upper arms? It seems odd to me even with round slaves. I intend to replace that bearing with a KP3L which I happen to have in stock and is called out, along with the K3L, as the proper bearing in the S-1S plans......
