When I get a rare opportunity to work on the -6A, I have been trying to follow Walt and Scott's suggestions.
I had a sinking feeling that the elevator center bearing was not rotating, so I removed the assembly. I believe it is called 411PP. I can't even get it to rotate when I clamp the shoulders between the ears of a vise. This pretty much confirms Walt's opinion that the center bearing was being used as a bushing rather than a bearing.
What is the recommended practice for replacing the bearing? I assume on a -6, the mating holes to the fuselage were match drilled during construction. Would it be best if I drilled out the rivets so I could reuse the ears that match the holes in the fuselage?
