Argus Camera ARGUS A2 manual Pre-war Shutter Face Plates

Fig. 7-4: Pre-war Shutter Face Plates

Let us take a look at the inside of the pre-war Shutter. Do not attempt to remove any of the screws on the inside of the shutter mechanism; they are difficult to replace. On this shutter, you can fire the Trigger while the Face Plate is removed, it will not affect the mechanism if it is working properly. With the Face Plate removed, the Shutter behaves as if it were set to T(ime); press the Trigger once to open the shutter and once again to close it.

The following letters refer to objects in Fig. 7-5.

A: This screw-headed spindle holds the Trigger in place. Only light lubrication is necessary.

B: These spindles deal with the B(ulb) and T(ime) functions of the shutter. Lubricate the spindle with the screw head. Be sure to allow some lubricant to flow between the two flat sheet-metal levers.

C: These two spindles hold the levers that open and close the shutter by rotating the D post. Lubricate them with care so that excess fluid does not flow into D. In pre-war A2Bs and A2Fs, there is an extra cam and spring on the spindle with the washer.

D: This post moves back and forth to open and close the shutter blades. Never put any lubrication in this area or you will jam the shutter blades! If your shutter blades are not stuck, you can open and close them very gently with this post.

E: These are the lubrication points for the delay mechanism. For every speed from 25 to 200, this mechanism delays the shutter blades to ensure that the shutter remains open for the appropriate amount of time. If your shutter blades do not close properly when set to 25 speed but work well on 200 speed, the problem most likely lies here.
