Hello! So I'm done on the focusing problem of my takumar 50/1.4 and my next step to clean the last element on the rear part. I remove the triplet lens from the block and I have a hard time unscrewing the brass and separating the two parts that holds the triplet and the last two elements. What is the correct way to unscrew this part? Should I rotate it clockwise or counterclockwise? It sits very tight and using a rubber tool to hold the two piece together seems no use

Found it! finally. The two brass retainers that holds the helicoid are put in reversed that's why it grinds into the brass ring when it reach the near minimum focus distance. Thank God I nearly gave up on this assembly. My only regret is I filed the filter ring screws and the brass retainers to make it a little short hoping it will solve the problem.

You're right. The entry points on this have 6 threads. And I forgot I successfully manage to reach the 0.45m minimun focusing distance but there's a catch, the screws that holds the focus ring and brass ring tend to bite unto the brass ring when it nearly reaches the 0.45m focus distance. Same with the screws that holds the filter rings. I've done this since last night for many times, and yes I still be able to keep my sanity from doing this, wish me luck.

I just bought the 8 elements Super Takumar 50mm f1.4 and sadly it has problem on it's mechanical parts, the focus ring is loose and it doesn't focus to infinity. I used a Sony A55 btw. As I tried to open the lens to fix the focusing mechanism, I set the focus ring to infinity before removing the casing and the helicoid and marked it. I also marked the brass ring where it should focus to infinity, then I rotate the brass ring in clockwise 7 times until it comes off and cleaned it and the helicoid. After applying lubrication on both the brass ring and the helicoid and tried to assemble it aligning all the marks I have done and put back the outer casing I noticed that the minimum focusing distance only stop in between of 0.5 and 0.45 on the meter distance scale of the focus ring. As I disassemble it to look for what causing it, I noticed that the 2 brass retainer that prevents the helicoid from spinning is the culprit. The 2 brass retainer touches the brass ring before it reach the minimum focusing distance of 0.45m. My question is, are there any lapses from my way of disassembling this lens? I can't find a detailed disassembly of this particular lens on the internet. Any help would be very much appreciated. Thanks
