Quote:You could try Lapping the gear. It sounds like a high spot,How often do you get it?You may have 2. I lapped one on a Starfinder. I just used my Electric drill and valve grinding compound. It tracked MUCH smoother!

Quote:Blueman and Orly,Thanks for the info. I agree, the first step is to clean and regrease the gears and then go from there. At short focal lengths it performs well but, I would like to go out past 1000 with an at6rc.
Quote:Blueman,Thanks for the heads up on dirt in the gears. Here in AZ we get a lot of fine dust. Both axes rotate very freely so I dont think the bearing are worn, even being so old. The gearboxes do come off with the motors. AP build, what can I say. This was a big improvement over the Orion Atlas and Meade LXD 75.John
