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

Full disassembly and reassembly of a Minolta MC Tele Rokkor-QD 135mm f3.5 lens. Lens is disassembled down to access diaphragm, mechanical components, optics, and body section individually.
This lens is fairly easy to repair, but a slight bit harder than the 55mm MC Rokkors because of the length of the lens body. Overall though, the lens is very easy to repair and maintain yourself.
Full time of video was around 40 minutes.

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.

My bad, it's extend the lens hood to reveal the grub screws, not focus out.

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

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.

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?

[@mistergiovanni7183]

No, In these versions come two groups of lenses on plastic mounts. And they don't have a threaded washer, that is, there is no way to disassemble them, they are sealed. If fungi do form inside these groups, until now I have not seen, nor do I know how they could be cleaned.

@@mistergiovanni7183 Ok, so I thought. Thank You.
