How to fix the stiff focus ring in Helios-44M 2/58 Re-grease with LM47 MoS2 OR Japan hobby tool #10

In this video I will show how one can fix the stiff focus ring, actually it's the stiff helicoids, because of old sticky grease that has dryet up during many years in this old Helios-44M 2/58.
I will at first try to Re-grease with the "LIQUI MOLY" LM47 MoS2, but I found it to be a little to stiff to move.
Then I with a really good result try to use the "Japan hobby tool" grease that is #10 and much softer than the LM47, even if the #10 has oil separated I think it's still a good grease.
It's just to show that there is not an universal grease for all lenses, sometimes it works and sometimes not.


As we are working with helicoids, we just need to remember to set small marks, BEFORE disassemble the helicoids and also measure how long/short the helicoids are at infinity, also remember to count how many turn(s) it will take to get off the thread, and also set marks where the helicoids get separated!
There is NO (0) repair manuals for those old lenses.
