Mamiya C3 - shutter problem
I bought a very nice Mamiya C3 from a fellow APUGer last week, who very honestly had described a problem with the shutter on the 80mm lens that came with it. I got a good price and 2 other lenses, and am very happy with the kit.
But of course, now I am wondering how hard it would be to strip the 80mm lens down to examine what might be wrong with the shutter. Taking the lens elements off is easy - but all that exposes is the shutter leaves. I don't know how to strip down further to the shutter mechanism.
Basically, no matter what setting it is turned to, it fires at about 1/60 sec. So it works, but won't change speeds.
The lens has "Seikosha S" on it, which I assume describes the shutter. Any tips on how to strip this thing down would be most welcome.
I can't speak to do-it-yourself work, but if you decide to send it to a shop, I've had Flutot's Camera Repair (http://flutotscamerarepair.com/) do work on my Mamiya TLR shutters and they have done a good job.
Thanks - I saw their webpage. But they have a backlog and I think it would be at least $80 or so to have them look at it - I think I could get a replacement lens for that.
If you have little or no experience with a shutter like this I'd have to advise against trying to DIY.
You need the correct tools to start and them sheeesh. These things have tiny gears, escapements, etc and only need a tiny bit of lube at the correct places.
I'm sure some crotchety apugger will come along and marvel how easily they fixed theirs, or how they gushed it with ronsonol and all was well but I'd look for another or get this one repaired by a competent repairman.
BTW, 80 bills is n't an exorbitant price for a full teardown and repair/lube.
80 bills isn't bad - but I can buy a replacement for the same price - I figured I could tear this one down, and even if I fail, I wouldn't be behind.

You could buy another for 80, but how soon will it need a CLA?
I've had Paul Ebel work on a Mamiya tlr lens that had the same problem, he did a great job since he's worked on a lot of them. Cost including return shipping was about $95, which I thought was fair.
Having your equipment maintained is part of the cost being a serious photographer if you need to come back to your client with pictures , not excuses.
True, I suppose that once CLA'd it would last a very long time.
True...but your next lens may have problems, too.

There use to be an *Bay seller with the handle of 'nikondave' that sold illustrated/breakdown repair manuals for all kinds of cameras and lenses; including Mamiya TLR cameras and lenses.
Also, along with Flutot's, (mentioned in post #2), for shutter repairs, apparently Mamiya USA (MAC), sold all/most of their remaining Mamiya TLR parts to KEH Camera, in Georgia. KEH may end up being the last bastion for Mamiya TLR repair, simply because they now have all of the remaining factory supplied repair parts for these cameras.
Unfortunately, they won't sell the parts individually.
They only use the parts when repairing lenses and/or cameras sent into their repair shop.
Another age related problem you're facing is your "Seikosha S" model shutter.
Those shutters were in the earliest lenses commonly called the 'Chrome' lenses.
There hasn't really been any parts available for those lens shutters for quite some time.
If you do opt for purchasing another lens, try to get a 'Black' lens, preferably one that has a 'Blue-Dot' on the shutter cocking lever.

*Note: This latest 'S' series 'Blue-Dot' lens is easily identified by the absence of any lens markings around the lens face.
