While working on my tower yesterday I discovered a problem with my M2 Orion 2800PX rotator. I noticed a lot or rotational freeplay. Probably about 20 degrees. In addition, the output shaft wobbles about its axis by about the same amount (10-20 degrees). I didn't know I had this problem so I was under the impression that the unit was working properly. I suppose the mast was holding the pieces together.
My question: Has anyone had a similar problem and what might be involved to fix it? Specifically, is this a DIY repair or will the whole unit have to go back to M2 for repair. The Operating Instructions has a drawing of the interior that leads me to believe the internal thrust bearing might be compromised. That could account for the wobble, but I don't know about the rotational freeplay.
Any theories or suggestions?
