Just finished a complete breakdown of a Meade LX5 drive base. I had purchased it recently and it must have been in a hot environment because the grease had liquefied and stained the RA circle as well as running out all over the drive base.
It ran. I plugged it in and it ran just fine in both axes and the Dec motor worked. It would speed up and slow down. It bothered me that it was greasy and stained so I decided to break it down and degrease/regrease. Restore.
So I did and it was a success. No more stains. Runs like new. Smooth as silk. I have attached a few photos. If anyone decides to do a restore on one of these drive bases I can answer questions. I learned a LOT.
