I got this lens on Craigslist yesterday for $75 with the Exakta camera, but the aperture blades are oily and the glass on the inside needs to be cleaned. Can someone walk me through some steps to take apart the body. I'm very good mechanically, but I don't know what things to looks for.
Thanks.
Here's a video of the back of the lens...

Not a good choice of lens to start learning....
This Primoplan is a very sought after lens and you could probably sell it
as it is for a substantial profit !
I'm somewhat experienced and i have fun doing this sort of thing but i strongly suggest
you start with some cheap lens..... just so you can mess things up and learn while doing it !
You could try this:
http://forum.mflenses.com/lens-repair-ebay-user-100-feedback-t61112.html
and still make a huge profit if ever you don't like the lens and decide to sell it.
I've done another lens from the Meyer-Optik lineup, it's probably similar in build except mine had an M42 mount:
http://forum.mflenses.com/meyer-optik-primotar-e-3-5-50-help-t59593.html
I was doing this beat up one above so i could learn enough to service a better copy i have...
i never did service my good copy.... doing the one above was no fun...
Having meddled in alot of lenses, i wouldn't advise you open up this Primoplan.
The last 3 Primoplan that sold on ebay averaged a price of $417...... a 4th one for repair sold for $174...

Send it to repair if you think it is worth to keep the lens. It is not as easy as you thing to get these chrome Meyer fixed especially you have never do something similar. You will also need spanners and other tools to open it.

Do not turn the aperture ring too fast if the blades become oily or you will damage the blades. My copy have two boken blades I have to remove them. Fortunately, the lens still function well even two blades are missing.

@Calvin
I picked up a beaten up copy recently and it has broken blades in it. Did you open the lens to remove the blades?

I agree, be very, very careful, these old DDR lenses sometimes have the weirdest designs. I am working on a Pancolar right now, and I had to strip it down almost completely for what I thought would be a routine CLA. |

+1. He has done some work for me...considering the amount of time and materials required to do this stuff right, he is almost doing it for free.
I've disassembled, cleaned and relubed helicals with expensive Microtools grease, re-filled engravings with laquer sticks, purchased lens wrenches, high end screw drivers and gum cones....it takes a 4-5 hours (if you are lucky and don't run into problems refitting the helicals back together...) plus $100 or more in supplies and tools to do right and not damage/scratch/strip screws/etc.....meanwhile this guy does the whole thing for less....follow the link to his page on the thread referenced by Mir. You will be happy!

I sent mine to a local repairman,his first opinion was the back glass was badly damaged by fungus and could not be cleaned. I am still on the fence as to what to do next.  Take the risk, that even though the damage on the rear glass may cause softness and loss of contrast,the other front elements may be in better condition.
I can use PP to help with any flaws?

Hi Mo,
My copy has haze in all the elements, Tried to clean them (with every toxic stuff i could get my hands to but nothing worked), still the image is really nice, of course you get very low contrast and in some conditions flare is bad but with PP everything can be corrected, i haven't seen a significant loss of sharpness in the images (IMO) and the bokeh is definitely there. I'll post some images later to show PP vs No PP.
Also, and i am not saying that you should do the CLAD okieisaak, but I completely disassembled my copy and it was fairly easy. Mine is M42 so it could be different than the exakta you have |

Mine is also the M42 version and thanks for your reply,you know how it goes when you have to make a decision regarding a lens. 
I have spent the morning tryng to find discussions out in googleland about rear element damage/scratches/fungus damage....they always seem to end up talking about the front elements.
The best thread I found was Attilas Broken Glass how it impact picture it certainly is the worst case scenario.
I would very much appreciate seeing the lens in question as well as the samples. Mine is at the repairmans now, and I think he is working on it today . I may have taken the biggest gamble/risk of my life on reparing this lens. I think the hardest part is not having done my usual test images, because the broken blades did not allow me to do that. Where I would have had a better idea on how badly this back element coating damage would have effected the overall image. I am flying blind on this one..perhaps emotion has gotten the better of me. 
the blades seem to be the easier to fix, the rear damage was a surprise "element" in this journey.
