General guidelines for installing this Contax kit
Tech Note. If you look at the hinge side of the back cover. you will notice a very small slotted screw attached to the hinge pin. That pin will retract if you push straight down on the screw with your finger nail. I find it much easier to work on the film back when it is not attached to the camera.
Hinge Seal, back cover. Install this starting at the top edge of the back cover, hinge side and work your way down.
Latch plate seal, back cover. Install by centering this seal on the door latch plate
Door channel seals, camera body. Install the upper and lower back cover channel seals starting at the hinge side on the camera body, working from right to left. The upper channel has the counter actuation lever. You will need to install this seal as close to each side of the counter lever opening as possible.
Mirror cushion. Now, with the utmost care, remove the old and install the new mirror cushion. Remember if any thing touches the focusing screen, it will likely be permanently damaged.
The most important and time consuming work is removing the old seals. Focus on clean, clean, clean. Clean the old residue from the door channels, mirror cushion area, door hinge area and anywhere else you are replacing the seals. The finest adhesive in the world will not adhere to that sticky, gooey residue that was once a quality light seal. Proper installation will give you thousands of light tight exposures.
