Cleaning and lubing the worm and worm gear

 

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?

Bill
