Leica LTM Another iiia shutter problem

[midniteson]

Following on from my previous post http://rangefinderforum.com/forums/showthread.php?t=91228

Although the 1000th speed seems OK, I have noticed that the slow speeds seem to have a problem now. When selecting, for example, half a second, the shutter will stay open for a different amount of time from one exposure to the next.

Any advice anyone?

Many thanks.

Exercise. A sticky slow train may free up.

If that doesn't work, CLA is the only option.

I've finally managed to sort out all the shutter speeds now 🙂
I removed the slow speed escapement and flushed it with lighter fuel, added half a turn to the second shutter tension and bingo ! I also found that drawing a cross on a piece of white paper and placing it in the film plane, then shining a light into the camera is a good way to assess if the curtains are travelling correctly and checking speeds.
Cheers.

Shutter Problem 1936 IIIa

Shutter Problem 1936 IIIa

Greetings ... I have been using my IIIa (225***) on fairly regular basis since I acquired it about six weeks ago and have been pleased with the results until I encountered a problem today with a stuck shutter. I have carefully removed the film. Actually, there were only three exposures taken on the roll.

My questions is as follows: Is there a way I can properly troubleshoot the problem to unjam the shutter or should I just seek the guidance of a competent repair service.

Thanks...

I guess that's a matter of confidence. I dabbled on a few Feds and Zorkis before I touched the Leica. I managed to completely kill a Zorki 4, but it only cost me £5, so no great loss. There is plenty of info to be found on the internet, so I would start by researching to see if you can ascertain just what the problem might be and then see how complicated the fix is. But bear in mind, if you do tinker yourself and make matters worse, then it will cost you more money to get it fixed by a professional.
