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

[iKokomo]

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!

Maybe try calling KEH, they might know or lead you to get repaired.
