Looking for input from the group on existing tutorials and advice on rookie mistakes to avoid in disassembling, cleaning, restoring a very old movement without wrecking it. I have an old Citizen Shokosha 10 jewel movement that appears fully wound and will tick a little if shaken. Sluggish, gummy. Appears to have some oxidation and need a good cleaning and oiling at minimum. I like this thing and I don't want to mess it up, but the only movement I've ever really worked on is an Asian 6497. This is about the same size. Any advice or links to existing tutorials would be much appreciated.
Thanks,
Dave

Step 1 is release the main spring gently.
Don't slip when using your screwdriver. It can scratch up your plates.
I would pretty much use the ETA 6497 instructions for servicing the movement

Take some photos of the keyless works and maybe geartrain after removing the plate - might help with assembly...

Careful cleaning parts with alcohol. Alcohol will dissolve shellac.
Best not to use alcohol. Ronsonol lighter fluid, naptha or automotive brake cleaner seem to work ok for me. (I'm an amatuer so please tread carefully with my advice.)

Well, I figured out where I went wrong. It wasn't the alcohol. Alcohol is still one of my restrictions since my accident.
I was using the wrong color of ball. Mine is yellow. Go figure.
