Full disassembly and reassembly of a Minolta MD Tele Rokkor-X 135mm f2.8 lens, including reconstruction of the diaphragm. Lens is disassembled down to access the diaphragm, mechanical components, and optical elements individually.

This lens is a bit harder to repair than the normal length Minoltas, and it is a later MD lens so it does use some cheaper materials and annoying design features.

Unless you absolutely need to, do not disassemble the diaphragm. I took it apart by mistake during my initial repair, but included the reassembly in my video in case anyone finds it interesting.

Full time of video was around an hour, including diaphragm reassembly.
