So my m42 adapter came in today. I thought, "oh, it has the aperture pin, I should take the lens apart." Well now I'm in a tough spot. The aperture ring fell off and now I can't get it back on. The two ball bearings that the ring slip over won't stay put. Every time I try to drop the ring onto the bearings they pop out of their sockets and prevent me from pushing the ring all the way down. I could get by with just one bearing but it doesn't sit well with me. Any idea on how to keep the bearings depressed?

Also, do I need to push the pin in? I haven't seen any threads about a preset Helios 44m and pin removal.

Let me know if better pictures are needed. These were taken in haste with my Tamron 17-50. I don't own a macro (yet).

Well for the time being I'm using one bearing. I'm too excited to test this bad bay out.

With the Helios 44M, you don't need to do anything with the pin. Sorry. The silver thumbwheel on the side of the lens allows you to switch to full manual aperture without messing with the pin.

Good luck with the remainder of the reassembly. You can get replacement ball bearings at micro-tools.com.

BTW...use a small glob of grease to hold the bearing in place while you replace the ring.

Thanks Steve. I played around with it and figured out that I didnt need to remove the pin. However the switch is a little too easy to knock into A. I may come up with a way to stiffen it. The assembly was a pain in the butt (all for nothing it seems haha). All that silver glop in my picture was anti-seize to hold the bearings. My experience in the automotive field taught me a thing or two it seems.

I'm super impressed with this lens. Even though I have the 44K-4, for some reason this lens feels like some thing entirely different, aside from the looks and weight. It almost seems better. My test shots are incredibly sharp.

Same optical formula as your 44K-4, but different build (eight iris blades, for instance).

I guess it's the novelty.
