Lynx 14 E - Shutter Blades Sticking

[Ambiguity]

Hey guys, hope someone can help me out with this one.

The guy i bought the Lynx 14 from promised it had just been repaired/serviced. 😛

He was halfway right, because who-ever serviced it, serviced it halfway right.

Say that 3 times fast.

Mr. Serviceman oiled/WD40'd/lube of some kind'ed the shutter blades inside the lens. So now, yup, you guessed, it's sticking. Rest of the camera works great.

I've tried to Q-tip most of it out, and have been using alcohol on the Q-tip to try to break the oil down/clean it off, which is working great for the side of the blades facing me. But, and those of you who have run into this should be able to see in your head what I'm describing: Clean, Cock, Fire. Nothing happens. BUT. If it tap very lightly on the Shutters, WHAM. Fire's fine. But then, when it's fired, there's oil residue all over the side of the blades facing me again. Which means: there's oil on the opposite side of blades, and when they open/shut, it scrapes more off onto the fronts. (since they overlap)

So my question is: Aside from deconstructing the lens down further, which I REALLY DONT WANT TO DO, Is there a way to clean the blades? Or inversly, is there an ACCEPTED way to lube them up? (Some super thin oil or something?)

It's down to patience and repeated cleaning.

You never lubricate shutter blades or aperture leaves. Never. "The guy" is not a camera repairman. I do not have a good feeling that you're going to get the goo out, ever. The shutter now requires a complete rebuild. I'm sorry to have to say that, I usually encourage tinkering.

I'm sorry, really I am. However - if you got a good deal on the camera, it may well be worth it to have the shutter done right. The camera/lens is wonderful, in my humble opinion. A terrific camera with a great lens.

You could try cleaning it continuosly for as long as it takes. Because the oil is brought from the back of the blade to the front of the blade, if you keep cleaning the fronts you may eventually remove enough so that the shutter will work reliably. I have cleaned some shutters that took hours to fix, the important thing is to remove all the oil brought to the front with cotton buds,"Q Tips" moistened with lighter fluid. If money is no object I would probably send it off to someone like Mark Hama. He is a Yashica expert and does very good work by all accounts.

A few months ago I serviced my Lynx 14 and a Mamiya Sekor Super Deluxe 1.5 which both have the same Copal SVE Shutter.

Grayhoundman is right as well as Bill: you have to fully dismantle the lens front (which isn´t too difficult) and perhaps the rear too. Shutters are designed to work dry, it is no oil, but a few drops of light grease sparingly applied on some surfaces. Usually this grease releases it´s oil and oils the blades then you have a stuck shutter. Or dry grease prevents some parts from moving freely. Either way, you may send #1: it to a reliable serviceman or #2: to DIY if you feel confident with your skills.

If you choose #2, I can send you a copy of my notes about dismantling both cameras´shutters. The only thing that´s important is that shutter assy is rotated 180 deg. in the cameras, but the general layout is the same with a few small differences.
In case you want it, just PM me.
