Replace dried out grease in a vintage Elgeet 13mm f/1.5?

Question

I got an amazing deal on a “for repair” Elgeet 13mm f/1.5. The problem with this lens is that the focusing mechanism is nearly frozen. Aperture works great.

I was wondering if anyone had a diagram or instructions on how to open this lens and replace the old grease?

Also, what are things that I need to be aware of when I open a lens? I have never done this before.

Lastly, what kind of replacement grease should I use?

Thanks!

Let a professional repair service center clean, lube and adjust. 
Viscosity is extremely important. 
If its too thick or heavy the lens will not work. 
The wrong kind will melt and run all over everything making a big mess.

Before you do anything, find the cost of repairing the lens; it could be low enough to make fiddling with the lens just not worth the headaches.

The internal tube has groves where ball bearings reside.  It could be that one of these bearing came out of its track.

I'm not a repair tech, so I can't give detailed instructions or anything to be concerned about. I would suggest doing a search for "how to repair a lens."  You might find a tear-down video that shows a similar style of lens being worked on.  It's likely that what you learn on these videos can be transferred over to working your specific lens.

Soak it in Safety-Kleen and use a wire brush on it. Works for my brake rotors.
