C8 Motor Problem

Hello all,
I have a C8 Deluxe that I bought new a couple of years ago. I detect a vibration comming from the RA motor. It can be seen in a 30mm eyepiece when doing solar/lunar observing. I do a lot of double star observing now and it has become quite apparent when pushing the power at night. It's very annoying.

I run off a 12V DC car battery so low voltage shouldn't be the issue. Anyone have any suggestions???

Remove the battery cover and check to see if the worm gear has come loose or developed some slop between it and the other gears. When I had my C8D, the same thing happened. Use a small hex wrench, align the gears again and tighten to a good snug feel. That should be the cure if it is indeed the gears being loose. Good luck!
