I started by removing the lenses because they needed to be cleaned to check their condition. A camera with broken lenses is more or less worthless and therefore not worth the effort repairing it.
Set the distance wheel to infinity. The front plate comes off easily by loosening the four screws (two above the lenses, two below the badge). Newer versions may need to have removed their focus lever first.
Reveal the focusing gear rack by removing the black bar on the right side (4 screws). The rack is loose now and can be taken off. At infinity, it is located at the low end of the travel way. position it back there with the wheel at infinity when putting the camera back together.
