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.
