2. Fitting the top-plate 370.01 U2.
As under Disassembly of Camera A2 but in reverse order. Check for correct functioning.
3. Check and adjust the distance between the lens mount and the film plane.
The film-path is checked with a Meßuhr [means dial-gauge - should be depth-gauge, surely?].
The distance between the lens-mount and the film-guides must be 44.72 ± 0.01mm. The film-
path should be set accordingly [presumably it means by means of shims under the mount - no
way of setting the film-path itself].
4. Check and adjust the mirror position.
(Collimator is set to infinity).
a) Example 1:
The greatest sharpness lies before the infinity stop of the lens: Bend upwards the adjustment
tab on the mirror base 370.03 U 13 (see Fig 1) until the greatest sharpness is obtained at the
infinity mark of the lens.
b) Example 2:
The greatest sharpness is not yet obtained at the infinity stop of the lens (i.e. the point of
sharpest focus would lie beyond the infinity stop): Bend downwards the adjustment tab on
the mirror base (see Fig 1) until the greatest sharpness is obtained at the infinity mark of the
lens.
C. Elimination of certain faults.
[NB. There seem to be two versions of the spring spindles. The illustrations are evidently the earlier
version. See the “Notes” for method for the later version.]
1. Cocking fails or is blocked.
Dismantle camera, as under Disassembly of Camera A.1 to A.3.
In the following only the disassembly of the cocking side will be described. The camera
mechanic determines which parts must be replaced and/or readjusted. No attention need be
paid to the position of the gear wheels relative to each other.
