Yashica FX-3 - Counter Resetting Faults; Counter Resetting Issues

Phenomenon
When the counter counts 36 frames or less and „ , , on
Counter release lever SP
then the back cover is opened, the counter is
not reset.
Cause
1. When forcibly tightening the counter G-1
before it completely enters the hole in case
the counter base is installed, burrs are pro¬
duced, so that malfunction of the counter G-1
is caused.
Z The counter release SP is clamped by the
counter base SS with the result that malfunc¬
tion of SP is caused.
3. Any blistering part of the sticked counter
name plate touches the top cover with the
result that the adhesives are pressed out and
touches the counter SP hook.
Repairing technique and confirming method
1. When the movement of the counter G-1 is not smooth, replace it.
Z After tightening the counter base, hook SP.
3. If the name plate is blistering, peel off the name plate, remove the adhesives completely, and then
re-stick the name plate.
Phenomenon
Although the winding lever is operated, the film counter does not move from S, or advances inter¬
mittently. (If pressing the back cover, the counter advances normally.)
Cause
Because the back cover cannot push the counter release lever to the full, the counter G-1 does not
perfectly engage the counter gear. Curving deformation.
Repairing technique and confirming method
• Visually check whether the phenomenon is caused by deformation of the back cover.
(When winding the film while pressing the back cover, if the counter advances, there occurs a curve.)
• If there is a step between the surface of the lock plate cover and that of the back cover, the curved
portion should be corrected.
Phenomenon
When the film counter counts 36 frames or less and the back cover is opened, the counter is not catches
something in the course of return.
Cause
1. Tightening of the top cover nut causes the top cover to press the counter SP hook, so that the
counter gear returns heavily.
Z Dimensional inaccuracy of the counter gear holder and the counter gear does not allow the counter
SP hook to make engagement.
3. The counter reset SP gets jammed in between the counter SP hook and the gear. The reset SP
protrudes from the gear and becomes entangled with the SP hook.
Repairing technique and confirming method
1, and Z Loosen the top cover nut little by little, and if the counter returns, replace the counter SP
hook with a new one.
Confirm that there is a play between the counter SP hook and the gear.
3. Remove the counter SP hook and check the entanglement of SP. If there is a play in the counter SP
hook, or the counter does not return from time to time though the gear is operated by fingers, press
the end of the side without notch of the SP hook by use of a screw driver. Again operate the gear by
fingers. The protrusion of SP is caused by deformation of the reset SP; correct it to its normal shape
or replace it.
