Olympus OM2n Shutter Curtain Bunching Repair

The Olympus OM series of cameras are known for their exceptional build quality and image quality. However, like any mechanical device, they can be prone to wear and tear over time. One common issue that can arise is shutter curtain bunching.

Shutter curtain bunching occurs when the shutter curtain, which is responsible for opening and closing to expose the film or sensor to light, becomes bunched up. This can cause a number of problems, including:

• Blurred images
• Uneven exposure
• Shutter curtain damage

In this article, we will discuss the causes of shutter curtain bunching in Olympus OM series cameras and provide a step-by-step guide on how to repair the issue.

Causes of Shutter Curtain Bunching

The most common cause of shutter curtain bunching is a displaced cord pulley. The cord pulley is a small wheel that helps to guide the shutter curtain as it opens and closes. Over time, the cord pulley can become loose or dislodged, causing the shutter curtain to bunch up.

Other possible causes of shutter curtain bunching include:

• Damaged shutter curtain
• Dirty or worn shutter mechanism
• Improper lubrication

Repairing Shutter Curtain Bunching

If you are experiencing shutter curtain bunching in your Olympus OM series camera, you can try to repair the issue yourself. However, before you attempt any repairs, it is important to note that you will be working with delicate parts and there is a risk of further damage if you are not careful.

Here are the steps involved in repairing shutter curtain bunching in an Olympus OM2n camera:

Step 1: Disassemble the Camera

1. Remove the lens and battery from the camera.

2. Remove the bottom plate of the camera by unscrewing the screws that hold it in place.

3. Remove the top plate of the camera by unscrewing the screws that hold it in place.

4. Carefully remove the shutter mechanism from the camera body. Be sure to note the position of all parts before removing them.

Step 2: Access the Shutter Roller Pulley

1. Locate the shutter roller pulley. It is a small wheel located on the side of the shutter mechanism.

2. Use a small screwdriver to loosen the screw that holds the pulley in place.

3. Carefully remove the pulley from the shutter mechanism.

Step 3: Repair the Pulley

1. Inspect the pulley for any damage or wear. If the pulley is damaged, it will need to be replaced.

2. If the pulley is not damaged, but is simply loose, you can try to tighten it by bending the metal tabs that hold it in place. Be careful not to bend the tabs too much, as this could damage the pulley.

Step 4: Reassemble the Camera

1. Reinstall the shutter roller pulley into the shutter mechanism.

2. Reinstall the shutter mechanism into the camera body.

3. Reinstall the top and bottom plates of the camera.

4. Reinstall the battery and lens.

Step 5: Test the Camera

1. Turn on the camera and test the shutter. The shutter should now open and close smoothly without any bunching.

If you are still experiencing shutter curtain bunching after following these steps, it is likely that the shutter curtain itself is damaged and will need to be replaced. In this case, it is best to take your camera to a qualified technician for repair.
