I'm looking for some help with the mechanical workings of the Meade LX85. The declination rotation has locked up even when the clutch is released. I have never had a mount apart before, but it seems as though the inner part of the declination assembly needs to spin independently of the outer part, until the clutch is tightened down. Is this correct (see attached photo)? The motor still drives the declination rotation just fine, I just can't release it from the motor. It works as if the clutch release is tightened down, even though it is loose. I have it apart and have tried to back it off, but don't want to force anything more than I already have. I have numerous ideas in my head about how it might work. If it is threaded and is just over-tightened, if it is a left handed thread and I am actually tightening it when I'm trying to loosen it, or if it is a bearing that is seized up.
Any help with it is appreciated.
