How to Change Light Seals on a Pentax ME Super Camera

The Pentax ME Super was produced between 1979 and 1984, and proved to be one of the most popular Pentax shutter-priority automatic cameras. A classic 35-millimeter camera, the ME Super is hard to service and even harder to find parts for. Over time, the light seals will ultimately need replacing.

Locate the small slotted screw toward the hinge area. Using the screwdriver, slide it downward to remove the film door.

Moisten a paper towel with solvent and clean around the edges of the film door, as well as around the pressure plate. Be careful not to jar the plate loose.

Soak the old light seal with solvent and let it sit for a few minutes. Using the bamboo tool (or a toothpick), remove the old seal. If any gunk remains, wipe it away with a saturated paper towel.

Replace the old hinge seal with a new one, measuring 6mm x 48mm, from the replacement seal kit.

Locate the two tiny seal pieces on the film door and remove them, using appropriate-sized pieces from the seal kit.

Using a paper towel soaked in solvent and your toothpick/bamboo tool, completely clean out the remainder of the film door slots. When clean, begin installing the seal strip at the end of the slot, with the glossy side out.

Press the seal strip gently with the bamboo tool/toothpick as you go around the film door, making sure to stop at the film frame reset lever, which is located under the serial number near the film door. Repeat this for the other side of the film door and the bottom slot.

Locate the mirror damper pad. It should be a strip of pad with a screw in the middle, housed in a circular area within the camera's backing.

Use your utility knife to remove the old pad, making sure to not get any of the old seal on the focus screen. Tilt the camera slightly as you work so the bits will fall out of the lens opening. If necessary, use some tweezers to get bits of old pad off, but don't use any solvent here to aid the removal of old pad.

Cut a strip of the 2.5mm foam into a 40mm x 3mm or 3.5mm piece. Using a scissors or utility knife, cut a V-shaped notch in the centre of that newly-cut piece to account for the screw that sits in the middle. Set this piece with a tweezers to assure steady-handedness and accuracy in this small spot.

Lift the mirror up gently to meet the newly installed damper pad, once the adhesive dries, and press against it. This keeps everything flush and sealed properly within the focus screen area.

Locate the latch end and remove that seal, as we have been doing throughout, with both solvent and a toothpick/bamboo tool. Cut a piece of 1.5mm thick open-celled foam, measuring 2mm x 43mm, and install on the latch end.

Go through all the seals you have just replaced and press down on them, gently and evenly, to assure they all have tight, uniform pressure throughout.
