Hello! I sure hope there is an OM-1 guru here because my poor little camera sure is sick!
So here is the story:
I have an old OM-1 and it had been sitting around for a while unfortunately. When I pulled it from it's bag and tried load in some film to use it, the advance lever it wouldn't budge. I looked around Google and read that sometimes a lever inside can become moved to the wrong spot through some black magic or something, so I opened the camera and after a little poking around I managed to make the camera 'fire'. After a bit more poking around I found that the camera's advance lever and shutter button work, but when the shutter button is pressed the little levers inside do not move far enough to make the camera reset.
This picture shows the camera without the advance lever 'armed' and nothing going on with it.

This picture shows the camera after I've used the advance lever and 'armed' the camera to take a picture.

Here I show where I have to move the lever ever so slightly in order to make the camera fire and reset. Pressing the shutter button moves this lever but not far enough to make a complete cycle.When I only press the shutter button the camera sounds as though it moves the mirror to take the picture but doesn't finish and move it back.

This picture is something I'm not too sure about at all anyhow. I am for some reason thinking that this circles lever arm thing usually goes towards the front of the camera and stays when the camera is 'armed' and ready to take a picture but in my previous photo you can see that it moves down but then automatically returns to the back of the camera.

Also, another great mystery is on the other side of the camera where the fancy gears and cams are.
In this picture you can see the camera's cam gear things at the 'rest' or 'unarmed' position.

In this picture you can see that when I press the advance lever the gears do not mesh by a tiny bit and will not spin together.

Here you can see that when I move the gears towards the back of the camera with the small amount of play in the gears, it now allows the gear to spin around as it is supposed to.

The thing about the gears not working though is that this didn't happen until I took off the bottom plate of the camera. I didn't mess with anything on that side of the camera or unscrew anything at all anywhere on the camera so I don't understand why it started this problem. If anyone has any idea what my problem could be, please let me know! I am really worried that this poor camera will have to sit around for a few months until I can afford to send it off and have it restored. I just want to take some pictures!
Anyways, thanks for your time everyone! |

Hi, you've got timing gear problems-the second photo indicates that th mirror mechanism is in the up position- (motor drive switch is closed) and 5th photo (1203) shows central gear at least one tooth out Correct engagement occurs when top gear, which is turned by wind lever on top plate, turns about ten degrees, then mates with the cut out section of central gear, which then turns the main cocking gear (Bottom one) to cock the shutter blinds in the body. Difficult to explain, and tricky to re-engage the central gear (which has a return spring under it) Easy when you know how, but difficult to teach by email. |
