DEFECTS CAUSES SERVICING
Rapid wind lever stops
while cocking, or does
not return
automatically.
Damaged spring (C19) Replace (C19)
Shutter does not wind.
1. When the shutter is released, the spill
(E08) remains lowered.
How to determine:
Turn the sprocket hard in the rewinding
direction. If the spill position is proper,
the sprocket turns a little. If the spill
remains lowered, the sprocket does not
rotate at all.
a. Due either to the damaged wind-up
shaft spring (C57) or to its slipping from
the wind-up shaft (C31), the idling gear
does not back up properly.
b. The bezel of the top idling gear
(E17) is not properly positioned.
2. The bounce stopper lever (E99) does
not slip off the bounce stopper (E97).
3. The pin adjust plate stud (C76) which
is broken is sandwiched between the
teeth of the gear.
NOTE:
This part was once temporarily used.
4. The shutter curtain especially the
ribbon of the 1st curtain is torn and
coiled around the 1st curtain wind shafts
(E35) (E36).
a. Replace (C57). Also replace (C31) if it
is worn
b. Properly reposition the bezel of (E17).
(Refer to Chapter II, 1 c.)
2. Readjustment is necessary. (Refer to
Chapter II, I, E, 2)
REFERENCE:
As the "A" part of the old type bounce
stopper actuator lever (E98) as illustrated
in the foil-lowing sketch is liable to bend,
replace it with a new one.
“A” part
3. Take out the broken piece and cut off
the erection point of (C76).
NOTE:
The wire-diameter of (E63) in cameras
equipped with this part is 0.12 mm and is
slightly narrower. Consequently, if move-
ment of the pinion coupler lever (E10)
is dull, replace it with an improved one
with 0.15 mm in wire-diameter.
4. Replace the shutter curtain.
