Mate overdefines assembly

Hey there, so I have this project that I'm working on, and for it, I need to do a system with bellcranks and pushrods. The thing here is that the measurements for the pushrod seem to be perfectly fine and to not have any issue whatsoever, but I'm getting the error that the revolute mate I'm using overdefines the assembly. I don't know where the problem is, since on paper it looks just fine. I'd really appreciate some help here.

Besides not being editable, this file does unfortunately not reveal much of your intent. You'd at least need some fixing points, bearings etc.. Maybe you should make a logical design before trying to throw constrains at it. It might then even explain itself.
Anyway, watch for your AOI, the effect of the wing downwash on the pretty short coupled elevator's AOA and the general CG of the whole ship. The fuselage has lots of lateral structure, but very little longitudinal. I have the suspicion the current config might mean asking for trouble.
If you're talking about the connection between elevator and push rod then use a cylindrical mate instead of revolute. I'm guessing of course since not able to try it out. Don't forget to put limits some where for elevator throw.
