Dear all,
I have been using Gemini G53f mount happily till now. The mechanical design as well as precision of this mount is fantastic. Few months ago I noticed some slip in the RA motor. I disassembled the motor according to this video: https://www.youtube.com/watch?v=NjaeGO3bHE0 and took it completely apart. I found the root cause of this problem.
There suppose to be a press fit between one shaft and the brass ring, but it is completely loose:

I tried to glue it, but it worked only for a while and got loose again.

Does anyone know where I can get the spare parts? The whole motor with the gear...
Unfortunetely, the manufacturer Andras Dan passed away few years ago and even his webpage geminitelescope.com is down.

Are we talking about the RA stepper motor or the reduction gear? If it is the former that can be easily replaced. If it is the latter you need to repair if you're handy and have access to the required tooling (I have if you're stuck, PM me if you need further help). BTW, I have a G41 and have already repaired it.
