Oil on the aperture blades In Ai-Nikkor 200mm 1:4

Actually there was just a very thin oil film, on the aperture blades In my old Ai-Nikkor 200mm 1:4.
And I would just show how one in an "easy" way fix it so the aperture assembly is free of oil, and it has to RUN dry! It will say NO oil in the aperture assembly or on the blades!

Remember to set small marks BEFORE disassemble the aperture assembly, and also measure the length from the back, without the aperture ring, and to the front of the aperture assembly tube, as I show in the video it should be around ~82,10mm at infinity.
