There are other sites on the web describing various self-service tips for the ME Super.

It's a great camera. I got back into film a while ago when someone gave me an ME Super. I tried an MX, a Super Program, and kept coming back to the ME Super. Finally paid for a CLA by Eric Hendrickson, figuring it was going to be my 35mm camera for a while.

I did open one up, and made a complete mess of it. There's some electrical connections and such to pay attention to, and some of the bumpers and foam were a bit tricky to figure out. I did get a nice pentaprism to use a paperweight!

The 50mm f1.7 is a classic lens. Even if the camera comes up a cropper, you did well.
