Does anyone have a manual teaching how to disassemble the nikkor

Dude you don't need a manual. Get a hammer preferably a rubber mallet and a scratch awl

You're going to fuck up your lens if you open it.

can you not send it to nikon for cleaning?

Don't fucking take it apart, I've tried. If it was one of Nikon's old metal and glass lenses where things are screwed together then I'd recommend you open it, but their new lenses are full of press-fitted and glued plastic parts that are impossible to handle without tools and solvents. Send it to Nikon for cleaning or hell, sell it on Ebay for cheap and get another.

Don't open it, buy a bag of silica gel and put the lens in it or put the lens in direct sunlight for a few days.

Already openned and removed all the fungus.

Only one part had glue, was a piece of plastic on top of the front element, the rest had screws.

Was actually very easy to disassemble.

Did you take pictures?

Most frontal elements are very easy to remove, even on some of the newest lenses.

On some lenses, you don't even need a spanner wrench or rubber stopper. These are mostly cheaper lenses, however, like my 70mm-210mm Sigma where if you screw on a filter too tight, the frontal element will come off with it during removal.
