BB. Assembly of camera EXA I/63.
1. Mechanism insertion.
As under disassembly of camera AA.3, but in reverse order. Check for correct functioning.
2. Top-plate 350.21 U 1 fitting.
As under disassembly of camera AA.2, but in reverse order. Check for correct functioning.
3. Check and adjust the distance between the lens mount and the film plane.
As under assembly of camera B.4.
4. Check and adjust the mirror position.
As under assembly of camera B.5.
C. Elimination of certain faults.
1. Shutter flap 350.04 U 5 falls back. [i.e. mirror is not caught by retaining spring]
a) Open right side (EXA) or remove top-plate 350.21 U 1 (EXA I/63).
As under camera disassembly A.2 or AA.2.
b) Bend apart the adjustable slot on the mirror cocking lever 350.04 U 2 (EXA), 350.04 U 7
(EXA I/63), see Fig. 2, until cocking stroke suffices and shutter flap goes past the retaining
spring 300.23 U 5 by about 0.5mm.
If the shutter flap falls back despite the adjustment of step b), then the mirror retaining spring
does not lie correctly in place in contact with the shutter release lever 350.04-8.
c) Remove the mechanism.
As under camera disassembly A.4 or AA.3.
d) Give the mirror retaining spring a bias [i.e. bend it down], being mindful of the mirror
setting.
e) Replace the mechanism.
As under disassembly of camera A.4 or AA.3, but in reverse order. Check for correct
functioning.
f) Close right side (EXA) or replace top-plate (EXA I/63).
As under disassembly of camera A.2 or AA.2, but in reverse order. Check for correct
functioning.
g) Check and adjust the distance between the lens mount and the film plane.
As under assembly of camera B.4.
h) Check and adjust the mirror position.
As under assembly of camera B.5.
