M6 shutter adjustment, I need some help

[Jagu]

Hi All!

I've got some problem with my new classical Leica M6 (it's not really new, I just bought it)
When I scanned my first film, I found a white strip (overexposed) at the right corner. It appears when I'm using short shutter speed. I know, it can be fixed and adjusted.
I have to adjust special screw on the bottom plate. But I've no idea wich one.

Any ideas?

Thanks alot

Whatever it's worth.....

I would get a CLA from someone reputable.

The shutter curtains each have a spring tension adjustment that controls how fast each shutter curtain moves. Both must move the exact same speed, or you get the kind of uneven exposure you see here. You cannot do this yourself, you need a test instrument that measures the speed of each curtain, and turning the adjustments too much can damage the camera. Pay someone who has the knowledge and equipment to do it right.

Thanks All!
I resolved this issue
When I got the problem with my new leica M6, (see pictures 1 and 2) I tried to find some information how to fix it. Obviously that shutter had some problem, but nobody know what happened exactly.
When I explored my camera I found that second curtain can't get into right position after shutter release (see picture 3). When the second curtain is in the wrong position there is gap, the light leaks thru this gap and makes the film overexposed.
I read alot of forums about how to fix this issue, but there were very few advices. Just one advice was helpful to me. - "When it happened you have to check the curtain's brake".
Only place where I could get the information how to adjust the curtain's brake was "leica M2 service manual" . M2 and M6 actually the same cameras 😉
In the Service Manual this is tipical problem. It can be fixed by - curtain's brake adjustment, second curtain adjustment, or replace the brakes.
I chose the simplest and the safest variant - brake adjustment.
It's a simple operation. All you need is 2 screwdrivers (cross and slot).
1. You need to unscrew 3 screw on second bottom plate.
2. Turn the brake adjstment screw counter-clockwise (pictures 5.6) on 10-20 degree (it's tight enough. be careful)
3. After that - check shutter on all exposures.


Now it works perfect 🙂

Its great that you managed to correct the problem but its been my experience that when these sorts of adjustments are necessary it indicates that the camera is in need of lubrication and cleaning. Even an M6 can be pretty old and if its been sitting lubs can stiffen etc. Its too nice a camera and too big an investment to risk damage.
