3. Assembly and Adjustment of Coupler Gear Parts
Install the coupler pinion (05039) on the 2nd curtain pinion shaft (05062), and fasten it with the coupler pinion
screw (05112) with a screwdriver inserted through the cut at the back of the body proper. Rotate (05039) to
such an extent as to facilitate this fastening while winding the wind-up lever.
Assemble the coupler gear (05031) after cocking the shutter.
When fastening (05037) to the body proper (01001) with the coupler gear retainer screw (05105), gear
(05037) with (05039), paying attention to the coupler gear stud (05113) so that it is positioned on the line
where (05105) and the pallet release rod assembly (06009) are joined.
Set the pinion coupler lever spring (05121) on the pinion coupler lever collar (05142) which is riveted to the
pinion coupler lever (05009), and set (05142) on the pinion coupler lever seat (05108). While setting it, hang
one end of (05121) on the coupler lever spring hanger (05096) and the other end on (05009). The clearance of
the tip of (05009) along the shaft direction should be such that the tip of (05009) does not get loose from the
coupler gear stud (05113) but does not contact (05037).
Insert LW13 onto (05108).
Fix the coupler lever pin adjust seat (0-03212) to the bottom main gear (03027) which is screwed into the
wind-up shaft (03042) at its bottom, then place the coupler lever pin retainer plate (03096) on it, and fasten
them with a screw (FM 2 x 3.5).
The part of (03042) where the long slit of (03212) should be fixed is as illustrated in Diagram 35, but
remember that when fixing (0-03212), the coupler lever pin-(03047) must be positioned as shown in Diagram
35 without fail. For this purpose, five types of (0-03212) are provided, each with varied angle of the long slit
to facilitate proper functioning.
