(danger! The cover can be marked)..

the typical E form.

1.2.- SPEED AND ASA DIAL
STEP 1: Set speed 1/500 and 100 ASA (not
shown in the picture). The cover of the dial is glued. Remove
it with an screwdriver.
STEP 2: Remove the central screw. The slot is very thin.
So, you have to sharpen an screwdriver. This screw is removed
counter clock-wise.
STEP 3: These are (ordered left to right) the pieces you
will find in the dial.

1.5.- SCREWS FROM THE TOP COVER
1.6.- TOP COVER REMOVED
The lightmeter is fixed by 2 screws. Furthermore
is glued but it is easily removed.
The prism and focus screen are also glued (Don`t
try to disassemble). This block is fixed by 3 screws (see picture).
If you remove it, be careful! There is a small lever coupled to
the mirror mechanism. It is the lever you see through the viewer
indicating if the shutter is cocked or not.
|
2.-BOTTOM COVER DISASSEMBLING
Remove 4 screws.
You will see the variable resistor (left side) fixed by 3 screws.
|
3.- FRONT DISASSEMBLING
Peel
off the front of the camera and remove 4 screws. You will be able to remove
the mirror cage in one block. Be careful. Several wires come from the
lightmeter board (sited in the bottom) and may become unsoldered.
Be careful too with the wire coming from the synchro of the lateral part
to a small plate sited venid the prism and lightmeter (see picture). It
is better to unsolder it.
