Minolta Rokkor 28mm lens with internal dust

[spoolman]

I'm going to be selling a Minolta CLE 35mm rangefinder and the 28mm lens that came with it has serious internal dust on one element. Any suggestions as to who does this type of cleaning ?. Any and all suggestions are welcome.

If the CLE lenses are anything like the SR/MC/MD mount lenses, they are not hard to disassemble and clean. Is DIY an option for you?

I tried to disassemble it but only got as far as the front elements and I didn't want to risk going further in case I did damage to the lens elements that would cost me more to have repaired.

I have worked on Guns and Guitar amps.
There are A LOT of Books/Literature, drawings and pictures that deal with both.
Are there similar take-down instructions for cameras and their corresponding lens.?

There probably are somewhere on the web but I'm hesitant to go further due to the fact when I tried this on other lenses/cameras/shutters I either screw it up so bad that I end up paying for it or there is a special tool that only certified repair people have access to.

Looking at photos online, it seems disassembly can be started with a spanner wrench. Likely also would need precision screwdrivers. SR lenses require these two tools also. Seems straightforward to me.

If you look at post #3 I did attempt to do this myself but only got as far as removing the front element. I did not feel comfortable going beyond that as I had no clue as to how to proceed further and given my luck,or lack of, in past attempts to fix a camera/lens or shutter I decided not to take a chance and damage the glass. Which is why I posted this inquiry.

I finally found a way to clean this lens. I just removed the rear element by unscrewing it and what I thought was dust was,in fact,white particles on the glass which I saw somewhere described as "Schneideritis". A quick shake of the lens element and poof !! the spots were gone and I can now shoot a test roll to see how the lens performs. Thank you to all who answered my inquiry.
