Frankly they are fiddly to work on and certainly difficult to understand how to dismantle, someone had already been in there and mashed a crosspoint screw and went no further.
Like the AF-S 70-300mm VR that I repaired before I didn't find much wrong, checked out the distance scale which is poorly mounted....the motor squeaked when turned by hand. The aperture lever/mechanism is baffling as I couldn't understand why the lens stayed half open when unmounted.....+4 glass and a head torch showed the mechanism was two levers that had to be parted.......not in the least bit obvious.
I also raided three dud SLRs and stripped the for springs screws etc.
Re-assembling the AF-S 80-200mm F2.8 is a more serious job with a lot more stuff to remember....so I'll go in there in the next few days!
Oh onward and upward!
There's an African proverb that says: "If you don't know where to go, look from where you come"
When the repairs guy here refused to repair my 24-200 since it's not worth the effort, he advised me " when disassemble the lens record it with video, this way it's easier to go back"
You lose nothing by doing it, video with phones is quite easy now
