4. Adjustment of Shutter Actuator Plate B (05140)
Timing in falling down of the shutter rod (05051) and flipping up of the mirror varies depending on how you
adjust the shutter actuator plate B (05140) with set screw (Set F 1.7 x 3). Adjust to assure that the mirror seat
(02009) flips up the instant the shutter rod (05051) is shifted, during its course of being pressed down, from its
upper tapered part to its narrow straight part where it meet with the bulb lever (05007).
At the instant the mirror seat (02009) flips up, there should be a clearance of approx. 0.3 mm between the
under-surface of the release plate (05004) and the upper surface of the collar of the intermediate gear retainer
screw (05092). Consequently, (05004) drops farther by approx. 0.3 mm the moment the mirror seat flips up. If
the clearance is found excessively bigger or smaller than the limit of 0.3 mm, adjust the shutter actuator plate
B (05140) again.
