Argus Camera ARGUS A2 manual Pre-war Shutter with the Face Plate removed

F: This lever rides on a cam on the Face Plate. When you rotate the Face Plate to set the shutter speed to B(ulb) or T(imed), this lever sets the mechanism in B to the proper position.

G: This lever also rides on a cam on the Face Plate. It controls the shutter speed from 25 to 200.

Reassembling the Shutter is trickier than taking it apart. The steps are the reverse of disassembly, but care must be taken to ensure that all of the various components, particularly the cams on the Face Plate, line up properly. When replacing the Face Plate, ensure that the Cable Release Socket lines up with its indentation on the rim of the Face Plate. The two(or three for the pre-war A2B and A2F) levers that ride cams on the Face Plate must be aligned properly or the mechanism will be jammed. Periodically test the mechanism while reassembling to make certain nothing is improperly assembled.
