start mount helios 44 request disassembly clarification assistance

sorry it's a bit dark, the camera is unpredictable , I didn't have time to edit process and re render it.

Wow, good for you! I went searching for a video like this yesterday and didn't find it, so landed up busking stripping mine down last night. The helicoid was jammed solid with gunk. Didn't take the ring off it like you did, just brushed some WD40 silicone lubricant in and let it seep, then dried it off and worked it free. And greased it. I left the lenses alone (they were clean, but interestingly one had three tiny bubbles in the glass! Can't see them in use). I left the funky step down arm alone too. The only thing extra I did, I stripped off the iris ring- it needed greased too -there's a wee screw that releases it, but also moves the aperture. I couldn't relocate it (neglected to leave the aperture fully open or closed). Twitchy moment, but discovered the whole ring screwed off eventually, so I could pen mark the receiving hole position. Gonna give it a polish tonight!

Glad the video had the potential to be useful if KZbin showed it when requested. The lens is growing in popularity probably due to difficulty finding 13blade m42 versions. I like the lenses with the bubbles in.
