Turn the inner focus helicoid until it is flush. Remove the focus distance scale that sits above the focus knob (my images above show that I removed it sometime before). Remove the four screws holding the lens plate guide. Note: the outer ring turns to lock the button up/down. If the shutter button is not moving freely you can take the opportunity to put some Ronsonol on it and work the gunk out of it. Note that the viewing lens is attached to this plate. You can now pull straight up to remove the lens plate. Put the shutter/lens back in the hole for safe keeping. There will be a charge ring washer on the bottom. You can turn the film winder to change position of one lever. Pull out all three one by one as you will have to slightly angle the top/bottom rings to unhook them. There is a shutter seat spacer ring in between. The top reset ring and bottom charge ring washer are hooked (on the left) to levers. There is probably is a focus adjustment washer, which may be stuck to the bottom of the shutter/lens when you pull it off. Do not lose these as these calibrate the lens for optimal focus on this particular body.įrom top to bottom there are four layers. Note: Try not to break off the wires, unless you have a soldering iron. Hold the shutter/lens while turning over the camera. The shutter/lens has a connection to the body because of the flash sync wires. Some people will just clean the outside of this, it really does not do a good cleaning, but it may be good enough to get the focus working again.Īt this point there is nothing holding the shutter/lens from falling out, so don’t just lift the camera suddenly. Note: The brass part in this image is the inner focus helicoid. Now you will have to use the spanner wrench to turn the outer ring (counter clockwise) off. There is a light shield around this, so just pull it out (you can turn it to loosen if it is not just pulling out). The rear of the shutter/lens is secured with a single ring screw. The first part is removing the shutter/taking lens. Now back to the focus of this post … literally. With a thin cleaning paper you can get under the Aperture/Shutter windows. You can now clean out this area with Ronsonol. I forgot to mention in my Shutter post about the back of the front cover. Make sure the focus lever is set to min or infinity. I am assuming that you have taken off the front cover (if not, look at my other post). Tools: tweezers, spanner wrench, slotted screw drivers, a scribe, Ronsonol, Super Lube. This stage of the repair gets into lubricating the helicoid. When the lube gets really gummed it makes it really difficult to move the focus lever. This makes focusing difficult or not possible.Ī couple of the Minolta Autocords that I have had displayed this problem. Over time the lubricants on the focus helicoid gets stiff. A common problem with many old cameras is the focus mechanism.
