So, just to be clear, you don¡¯t recommend disassembling the head so the worm gears are fully exposed for a more thorough cleaning? ?Just paint a little degreaser on the gear and clean it off as best you can? ?Then follow with adding some lube? ?Run the motor to a new location and repeat?
Are there instruction anywhere for how to get into this thing, or am I asking for trouble?

as I mentioned before, generally the problems we see with things seizing up are with the needle bearings
You can of course inspect the worm for dirt or grease build up.?
if it's there, you can wipe it down with WD40 or alcohol and relube with a teflon grease/superlube/arctic lube (we do not recommend lithium grease)
rotate the worm gear so the grease is spread through the grooves
Hi Bill,
Absolutely use any common solvent to remove all old lube, alcohol is a good final rinse but letting the work rest or if you have shop air is just as good to evaporate the solvent. Relube using SuperLube with Syncolon (Teflon) NOT the silicone stuff, you can't get rid of that stuff! Order it from Amazon and like magic is arrives in a day or two!
Use enough but not too much, if it is blobbing up that is too much. It is better to remove and reapply fresh grease when it gets contaminated and having done it will make it easy the second time. I do this every two years or sooner if I have been out in the desert a lot and give the mounts a through once over checking for loose screws and things gone askew and setting them right.??
It's like changing your vehicle's oil, easy once familar with the job. Keep us posted!

Group,
I have been having problems on my 10 year old GM8 with periodic jerkiness when centering while viewing through the eyepiece and with RA motor lag messages. Brian suggested that after 10 years it was time to clean and lube the mount.
I took it apart and cleaned and lubed the needle bearings as Scott showed in the YouTube video. That seemed to go well and the bottom needle bearing on the RA axis did seem stiff or possibly even frozen.
I was wondering if the worm and worm gear needs to be cleaned and lubed at this time. That was not shown in the video and it seem like getting into the worm gear is somewhat involved. Is this also something I should tackle, and if so how do you do it?
