USCamera Light Seal Kit Install – Petri FT and FT II

Before you do anything, please read the general removal and installation instructions here.

Next,  take all of the seals out of the kit and lay them out on your work area. This kit includes,

2 x 1mm – Back cover channel seals on the camera body
2 x 2mm – Back cover channel seals on back cover (much wider and thicker than the camera body seals)
1 x 1mm – back cover hinge seal for camera body
1 x 3mm – mirror cushion

Tech Note. It is easier to install the back cover hinge seal and work on the back cover with it removed from the camera (but not necessary).  It is difficult to remove the hinge pin, so you will need to carefully lift up the front grip side leatherette near the hinge it will expose the 2 back cover retaining screws. If the leatherette is very brittle and breaks into pieces when attempting to lift it up, it is best leave the film back attached to the camera.

Door channel seals, back cover.  On the latch end of the film back,  measure 3mm down from the edge of the back into the lower door channel and mark it with a pencil. Measure and mark the top door channel also. That is the starting point for the back channel seals. Starting at the mark you made, remove the backing and install the lower seal on the back cover from right to left.  Do the same for the upper seal.

Hinge seal on camera body. This seal is installed by centering the seal between the upper and lower door channels on the camera body.

Door channel seals, camera body. When installing the channel seals on the camera body, always start at the hinge side and work to the left. The top and bottom body seals are the same length.  When installing the upper seal, cut off a 13mm long piece and install that seal starting at the hinge side to the counter lever. Then install the rest of upper seal from the other side of the counter lever to the rewind end of the camera.  Then install the lower channel seal on the camera body.

Mirror cushion. Tech Note. Disassembly required. Installing the mirror cushion requires some disassembly.  It is not possible to install the mirror cushion otherwise. You will need a good quality #00 or #000 Phillips screwdriver. Wiha / ACE are good quality brands and easy to find.

Notice the top of the lens mount has the red dot.  Remove the 4 lens mount screws and carefully lift the lens mount up and look for any shims under the mount at each screw hole.  Many times they are glued to the mount or mount base. If they happen to be loose,  just make sure you note the position and placement of the shims as that is critical for focus accuracy. Now remove the chrome cover ring then the black plastic light shield and that will expose the 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.

Reverse the order of disassembly above, replace the lens mount and related parts.
