I. FILM ADVANCE & SHUTTER RELEASE MECHANISMS
1. Film advancement not performed smoothly:
1) Improper selection of CA8844 (Lever)
8844 is available in following 3 types. Adjustment should be
made on the timing of brake release by replacement of 8844
with a proper type.
Caution:
Some of 8844 are bent for adjustment of engagement between
8828 (Shaft) and 8833 (Plate). This should be checked at
the time of replacement.
CA8844a
CA8844b
(for slower timing)
CA8844c
(for faster timing)
If, even upon replacement with 8844C, the film advance motion
is not smooth yet, the portion marked A may be slightly
hammered out. (Do not work excessively, as it will cause the
spring to be readily pressed from the beginning of the motion.)
