I can't really help you, but I do remember when I purchased mine. It was discounted heavily because the case it came in disintegrated and got dust all inside the lens, including all over the internal lens elements. I was able to open it up myself and clean everything out. I don't remember how I did it and don't have any photos or anything from that time, but I do remember that that was my first or second lens to ever take apart, and it wasn't as difficult as I thought it would be. I remember the only thing that really gave me trouble was keeping the room dust free. I recall having to disassemble and reassemble the same parts over and over again because more dust had gotten inside by the time I got the next part installed.

Have you taken apart a lens before? If not, I probably wouldn't start off with this one, just because it's such a nice lens to begin with. It would be wise to practice on a cheap lens first, as it'll give you experience using a spanner wrench (which is easy to have slip and scratch an element) and allow you to establish a workflow so you don't accidentally install a lens element upside down. Once they're out of the barrel, the tops and bottoms tend to look pretty much the same, so it's really easy to space out for just a second and forget which way something goes.

https://takumarguide.weebly.com/1--14--50-358-8-element.html shows a lens diagram. The front of the lens is on the left. The gap between the two concave elements is where the aperture is. 3 air spaced elements front, 3 cemented and 2 air spaced rear. Should not be difficult to do. The rear element sticks out from the barrel and is easily damaged.
