GOTO and Tracking seem normal. This is only some positions, its like its from the base (computer), very faint clicking.

[Re: AlienRatDog]       #1095040 - 08/14/06 11:13 PM Edit   Reply   Quote Quick Reply   My 10" GPS started doing this after about 2 years of use. The noise would show up when the scope was unbalanced. I posted this message on the Yahoo group last June: "I finally took my scope of the pier to find the source of the loud ticking in the RA drive. I found a number of things wrong when I opened the base of the scope. 1. There was excessive backlash in the replacement steel gears. I had replaced the plastic gears with Bucks Gears about 2 years ago. At that time I had adjusted the backlash out. I re-adjusted the screw that controls the backlash. 2. The spring loaded worm gear was to tight. I backed off the stop screw 1 turned. 3. There was little or no grease left on the steel replacement gears. So I re-greased the steel gears and the worm gear. I re-assembled to scope and tested it. The ticking sound is completely gone. It also used to be really noisey during high speed slews. The gears would "ring", that noise is gone now too. In a few days I'll check the Dec gears as I am sure they may need to be re-lubed also. I guess I need to do my yearly PM every 9 months." -------------------- -Marcus The problem with free speech is even the stupid have a voice. http://jatobservatory.org 12" LX200R on a Paramount ME Post Extras:       Joseph Gillman Carpal Tunnel Reged: 12/06/05 Posts: 2358 Loc: Boothwyn, PA Re: Clicking sounds...

If still clicking continue submersion another 24. Marcus, what grease do you use? -------------------- Jerry LX200ACF 14", Tak FS 152 & TOA 150 AP-1200 & Mach1 Post Extras:       JAT Observatory Space Freak Reged: 02/20/05 Posts: 5866 Loc: Eastern PA Re: Clicking sounds... [Re: JerryWise]       #1100038 - 08/17/06 07:04 PM Edit   Reply   Quote Quick Reply   I actually use 2 types of gease. On the Paramount I used Dynatex 49598 Motor Assembly Grease and have also applied it to my LX200GPS. Before that I had been using Mobil One Synthetic Grease on my LX200GPS mount as well as the gearing on the observatory's dome and shutters. -------------------- -Marcus The problem with free speech is even the stupid have a voice. http://jatobservatory.org 12" LX200R on a Paramount ME Post Extras:       JerryWise Postmaster Reged: 12/26/03 Posts: 7007 Loc: Lexington, SC Re: Clicking sounds...

It was in a thread exchange you had a good while back. -------------------- Jerry LX200ACF 14", Tak FS 152 & TOA 150 AP-1200 & Mach1 Post Extras:       Pages: 1 Previous   Index   Next   Threaded   Extra information 1 registered and 0 anonymous users are browsing this forum.
