I have not had one leak around the sides but have had two leak where the dark
slide goes in.
One gave me a light line between frames with very faint fogging and only in
bright light.
The other gave me fogging over the entire frame in almost any light.
Replacing the foam around the door is not a bad idea but I doubt it will
solve
the problem.
I did my own because I got tired, after the third time of returning it to the
shop and not having it come back fixed, of wasting film. They refunded my
money but didn't pay for the film. The following is what worked for me,
I do
not do camera repair for a living so use the following at your own risk.
With back off camera:
First remove any film, the insert and the darkslide (by inserting the end
of a
pen and depressing retainer pin while holding pushing darkslide in to relieve
pressure on pin). Anyway there are a number of small screws around the
perimeter of the plate that goes against the camera body, 10 on the back
I am
looking at. They are small and delicate, you need to remove these to get the
cover off. Do not remove the two (one on either side) of the dark slide, you
will get those later.
Gently pry out the plate, it will probably take a little work but it will
come,
JUST BE GENTLE so as not to bend it. Once out you will find there is a
"protrusion" covered with felt, under the felt is a spring loaded rod
attached to
the back side, this is used to close the darkslide slot when the
darkslide is
removed. On both the backs I had that leaked this slide was stuck open
on one
or both ends from corrosion. By removing the remaining two screws you
free this
up and it can be cleaned.
I removed all the old felt, most of it peeled off, went to the fabric
shop and
bought some regular velvet and replaced what I had removed using contact
cement. Make sure to not over do it with the contact cement, a little
goes a LONG way.
When done reassemble in reverse order.
This corrected the problem in both backs and saved me almost $100 a back to
have them rebuilt. One word of caution, the screws are small and
fragile, if
you bugger one up or break it off it may not be the end of the world but
it is
a real pain SO GO EASY. Also make sure not to drop anything in, fool
with or
remove the gears you can see when removing the cover, you are just asking for
trouble.
By the way, my greatest fear when I started rebuilding the first back is
that I
would remove the cover and a Kajillian Springs & parts would go flying
everywhere. This doesn't happen, but I do make a habit of working on a clean
WHITE flower sack (smooth) towel. Make it easier to find little screws when
you drop them and keeps them from ending up on the floor. Also make sure you
have a little bowl handy to put your parts in as you remove them.
This project is best done when your spouse is gone, your kids are gone,
the dog
& cat are gone so there are absolutely not distractions....
Good luck and let me know how it turns out!
