Minolta MC Tele Rokkor-QD 135mm f3.5 Lens Full Disassembly 

Judging by the comment section I guess this video helps like 5 people a year top. I was lucky enough to be amonst those. Picked up a cheap 135mm 3.5 that had an oily aperture. Thanks for the great video ! My lens is now clean and fully fonctionnal.

Big thumbs up! This helped me out in such a massive way!

Thank you for the valuable update that was very helpful to me.

I found a MC(I) Tele Rokkor 200mm f4.5 with stuck aperture and focus stop issues. The construction is almost identical to the lens Matt shows here. Focusing all the way out reveals 3 slot head grub screws on the side of the lens hood assembly. Loosen and pull off lens hood assembly. Optics unscrew and diaphragm assembly come out just like this 135. Most importantly for me, the bayonet assembly comes away from the lens barrel ( 3 screws on the side of the ring with the depth of field markings, so thanks to Matt I knew it was safe to unscrew those screws. I was able to fix both issues. Nice lens.

Thanks so much for the video! This really helped me feel a lot more confident before CLAing this lens. Only suggestion for viewers that I have is you may need acetone to loosen the set screws for the focusing ring. Otherwise, this is a really simple lens. Good practice before servicing more complicated and valuable designs.

Thanks a lot. What is the pushing knob close to the red dot is for? Thanks

i like ur video on these lenses , maybe you could add ur feedback on the optical performance ?

Are you familiar with the CPC 135mm f2.8 MC lens? My aperture ring doesn't work .

He didn't say anything about the disassembling of the front lens-group. Is it glued or what? Are the lens elements separable or not?

Not Rocker...Rokkor
