Hexanon AR 50mm F1.7 - accidentally came apart, what now?

[anvo]

Hello there

Long time lurker, first time poster.

I recently got myself a Konica Hexanon AR 50mm F1.7 lens along with a T3 Autoreflex, unfortunately after I received the lens, I realised that the focus ring was a bit loose when trying to focus, so i tightened my grip, and it seemed to make the lens focus. However after doing that for a while, the lens came apart and split into three pieces.

The first thing I did after these came apart, was to tighten the three flathead screws on the focus ring (seen on image #4), since these seemed to have something to do with it being loose in the first place.

Then after some trial and error I managed to align the pin seen on the left part of the image with the whole in the lens part, while the focus ring was also attached, such that the focus ring would move the lens part back and forth without rotating it along, as was what happened when it came apart in the first place. However the distance seemed to be off, and it didn't quite work right, and after some research I think I misaligned something while trying the reassembly. (Sorry my terminology is weak, I'm not a native English speaker)

I got the focus to stop at infinity at one point, but the focus seemed off when looking through my T3, and when going towards a shorter focus it does not stop at the lowest setting, it keeps going untill the lens snaps apart again.

I hope someone has some general tips for reassembling an old lens like this, that has accidently come apart.

I was also wondering if it might be worth reapplying some fresh grease for the threads since the lens is already taken apart.

Thanks in advance.

Best regards
Andreas
