How to service the Nikon Nikkor 28mm f/2 ?

Hello Friends,
Today I show you how to repair one of the best lenses I have ever used, the Nikon Nikkor 28mm f/2 Ai. This lens was sent to me for repair, the very lucky owner found it cheap but in dire condition. It was dirty, the aperture clicking was weak, and the focus was very stiff. In short, the lens wasn't pleasant to use.

Here I show you how to clean this marvel
