Before was the outside, now the inside of the camera.
I dismounted and serviced the shutter, Compur type with T, B, 1 to 250.
After I started with the focusing mechanisms, here its focused to minimum distance, those two inner rails have old dry grease, I could move but not as free as it should, so first of all is to free the shutter plate from the focusing arm shown at left.
The plate is already free from the focusing arm and we can see the chain which pull the shutter plate to the front (exit way), the pulling is done by the big spring that you can see in the first picture. There is a circle metal piece that pick up the chain around itself thanks to that spring.
Here its out of the camera body, those rails along the front plate have being cleaned and lubed again.
Detail from the pulling mechanism, the chain is picked up through the groove of that "wheel", old grease everywhere to be cleaned.
After clean the lower shutter plate, two complete turns of that wheel have to be done to get enough pulling strength.
And reattached now to the rails carefully.
The most difficult part was to put in place the focusing arm to the shutter plate:
Shutter plate already pulling to escape + spring to close the focusing arm + washer + leveler + focusing arm+ screw
The shutter had three metal shims plus one handmade cardboard shim, also the shutter place isn't perpendicular to the film plate, about 0.6-0.7mm of difference which is a lot, so on the lower part I put two quarter 0.3mm shims plus the 3 metal shims, the collimation looked good with the DSRL, now its it to test the camera and see...
Thank you for watching, I love to work in this camera!
