TROUBLE

CAUSE

REMEDY

Shutter blades buckle

(cont'd)

Shutter operates
instantaneously
on B (bulb)

Both flash settings are
below the millisecond
tolerances (fast).

Both flash settings are
above the millisecond
tolerances (slow)

Blades opening too far.

Blades closing too far.
No clearance between the blade

controller latch and the BLADE
CONTROLLER LUG, figure 14,
when the shutter is in the tripped
position.

The lug on the side of the rec
tangular opening in the trigger
is out of adjustment.

The tension is too great on the

WINDING GEAR SPRING, figure

4.

There is not enough tension on
the winding gear spring.

The winding lever may be bind
ing around the central opening of
the cover or on the speed INDEX
PLATE, figure 2.

File and burnish the blade controller LATCH

at point "A". (See figure 7.)
Swedge mechanism plate at "B", figure 14.
Swedge the mechanism plate at point "C,"

figure 14, such that this point acts as a
stop for the SETTING LEVER with stop
stud, figure 12.

Bend the lug on the trigger in or out until

proper adjustment is achieved.

Relieve the tension slightly on the winding
gear spring. However, there must be enough
tension on the spring to permit the winding
lever to carry through on both the F and M
flash settings.

Place the winding gear spring under slightly
greater tension. Care should be taken dur
ing this adjustment not to disturb the trigger
latch.

Try lubricant, or replace the WINDING
LEVER, figure 2.

The F (short stroke) is
within the millisecond
tolerances but the M
(long stroke) is fast

Constant flash short

Both flash settings are
extremely fast

THE FLASH RETARD PALLET,
figure 3, is not meshing properly
with the winding lever.

The flash retard pallet may be
binding on the speed index plate.

Cracked contact insulating
BLOCK, figure 8.

The contact spring may be bent
and touching either the contact
lever or the cover.

The trigger latch may not be
falling into the slot on the cover.
This allows the shutter blades
to open too soon.

With special Tool No. 657, turn the eccentric
post so that the pallet will mesh firmly in
the teeth of the winding lever. Make certain
the post is tight on the cover after making
this adjustment.

The index plate will be marked at the bind
ing point. File the plate at this point to
allow clearance for the pallet.

Replace the contact insulating block. The
shutter should be checked independently of
the camera. If the shutter is working prop
erly, refit it to the camera. If the short
persists, check the case insulating bushing
NUT, figure 8, to see that it or any part of
the contact wire is not touching the focusing
tube or light guard.

Re-form the contact spring.

Add more tension to the trigger latch spring.

5

TROUBLE CAUSE

REMEDY

Both flash settings are
extremely fast (cont'd)

The end of the trigger latch is
bent back, toward the trigger.
When the latch falls into the
slot on the cover, the bent latch

will permit the trigger to go

down far enough to trip the
shutter blades.

Re-form the end of the trigger latch by
bending it slightly toward the winding gear.

After the shutter has been assembled, it can
be checked to see if the shutter blades will
open before the winding lever opens them.

1. Set the shutter.

2. Set the winding lever.

3. Holding the winding lever down, release
the shutter. The shutter blades should not
open while the winding lever is down.

The sequence of disassembly is as follows:

1. Front lens mount, using Tool No. 501-0.

2. Diaphragm control ring RETAINER WITH
SYNCHRO SCALE, figure 2.

3. Diaphragm control RING SPRINGS (one or
two).

4. DIAPHRAGM CONTROL RING.

The sequence of reassembly is as follows:

1. Diaphragm control ring, fitting the notch
opposite the pointer over the projectinglever
on the DIAPHRAGM RING, figure 2.

2. Diaphragm control ring springs (one or two).

3. Diaphragm control ring retainer with syn
chro scale.

4. Front lens mount, using Tool No. 501-0.

SPEED CONTROL RING

The sequence of disassembly is as follows:

1. Diaphragm control ring, paragraphs 1-4
above.

2. DIAPHRAGM CLICKSTOPSPRING, figure 2.

3. Speed and diaphragm INDEX PLATE and the

SPEED ring CLICK STOP SPRING.

4. SPEED CONTROL RING.

CAUTION: If the WINDING LEVER
is disturbed, the flash timing will
have to be readjusted.

The sequence of reassembly is as follows:

1. Speed control ring with shutter in tripped

position. Be sure the projecting lug on the
BULB LEVER ASSEMBLY, figure 5, the

studs on the retarding SECTOR WITH STUD,
figure 6, and the PALLET BRACKET with
stud assembly are resting against the inside
edge of the speed control ring and are not
underneath the ring.

2. Speed ring click stop spring. The crimped
side of the spring should face toward the
back of the shutter.

3. Speed and diaphragm index plate.

4. Diaphragm click stop spring.

5. Diaphragm control ring, paragraphs 1-4
above.

WINDING LEVER

The sequence of disassembly is as follows:

1. Diaphragm, control ring, paragraphs 1-4
above.

2. Speed control ring, paragraphs 2-4, above.

3. WINDING LEVER, figure 2.

The sequence of reassembly is as follows:

1. Apply a thinfilm of grease (Texaco Unitemp-
RCX169 Grease) to the teeth of the winding
lever.

2. Set the shutter.

3. Winding lever, with the sixth or seventh

CAUTION: Do not touch the TRIGGER

LATCH, figure 5, as it may release

the winding gear spring tension.

Trip the shutter and lightly hold the wind
ing lever down around the central collar on
the cover. As the shutter is tripped, the
end of the latch should fall into the slot on
the cover. If it does not, add more tension
on the TRIGGER LATCH SPRING, figure 3.
Check for a bind between the trigger latch
and the TRIGGER ASSEMBLY, figure 5, at
the point of attachment. The winding lever
should contact the trigger latch; push the
latch out of the slot in the cover and open the
shutter blades. After the shutter has been
tripped, the latch should return to a position
where it is resting on the ledge just above
the small slot in the cover.

After the trigger is depressed, allow it to
return to its proper position very slowly. If
there, is too much tension on the trigger
latch spring, it will tend to retard the action
of the latch and the trigger.

FLASH SYNCHRONIZATION

After the shutter is assembled, it must be
checked to see if the winding lever will always trip
the shutter blades when the trigger is released very
slowly. Set the shutter and the winding lever. Re

lease the shutter, allowing the winding lever to
return slowly. The winding lever must trip the
shutter blades.

The shutter must be checked to see if the shutter

blades will open while the latch is still in the slot
in the cover plate. To check for this condition, set
the shutter and the winding lever. While holding the
winding lever in the fully wound position, depress
the trigger. The shutter blades should not open
while the winding lever is being held down. If they
do, refer to the Trouble Chart. (Both flash settings
extremely fast; see page 5).

Check the operation of the winding lever safety
latch. When the shutter is not set, the winding lever
must be locked in the unwound position. After the
shutter has been actuated with the winding lever, the
lever must return fully and become locked in the

unwound position.

The flash settings on the shutter should be timed

with reliable shutter testing equipment. The toler
ances of the delayed action in the shutter for syn
chronization with the flash bulbs are as follows:

F (short stroke)* 3 1/2--5 1/2 milliseconds.
M(long stroke)* 12--16 milliseconds.

*From instant of contact until the shutter blades

first begin to show light.

FLASH SHUTTER CONTACT CONVERSION KIT

A more satisfactory operation of the shutter has
been achieved by a change in the design of the
flash contact parts. The old-style parts, which
are to be discarded, are no longer available. They
are to be replaced by the parts furnished in the
Flash Shutter Contact Conversion Kit No.121352 —

must be approximately .005-inch clearance
between the contact lever tail and that por

tion of the trigger latch which engages the
tail. The contact points must be in contact.
If there is no clearance or if there is exces

sive clearance the spacing maybe controlled
by bending the contact lever tail in or out.

Allow the winding lever to go to the "at

rest" position. Depress the trigger and
watch to see that the flash contacts do not

close. If they close, hold the end of the con

tact lever tail toward the shutter case, place
a screwdriver blade against the vertical

portion of the contact lever tail near the con
tact lever stud, and apply pressure toward

the shutter blades at this point.

With the shutter tripped there must be
approximately .005-inch clearance between
the contact latch spring lug and the side of

the contact lever. This is to assure full

pressure of the contact lever latch into the
star wheel.

While pressing the trigger down fully,
watch the contacts to make sure that they
do not close at any time. If they close, the

contact lever tail on the contact lever has

been bent too far and it should be moved

back slightly. If necessary, the winding
lever should be stoned at point "A",figurelO.
Corner "B" must be square.

The sequence of reassembly is as follows:

1. If necessary, clean the shutter blades thor
oughly. Hold the blades carefully to avoid
bending and clean their surfaces with a soft
cloth. Fingerprints on the blades will cause
corrosion.

8. If the shutter is of the flash receptacle

plunger type, insert the threaded end of the

plunger assembly in the collar end of the
terminal body insulating sleeve. Then in

sert the assembled parts in the terminal
body. Place the case insulator washer on the
end of the plunger. Position the end of the
contact spring over the opening in the shut

ter case and push the threaded end of the
plunger through the opening in the spring.

Fasten the plunger with the terminal nut.

Insert the case insulator in the hole in the

side of the shutter case, near the stud on the

trip the shutter blades when the trigger is released
very slowly. Set the shutter and the winding lever.
Release the shutter allowing the winding lever to

return slowly. The winding lever must trip the
shutter blades.

The shutter must be checked to see if the shut

ter blades will open while the latch is still in the

slot in the cover plate. To check for this condition,

set the shutter and winding lever. While holding
the winding lever in the fully wound position, depress
the trigger. The shutter blades should not open

while the winding lever is being held down. If they
do, refer to the Trouble Chart. (Both flash set
tings extremely fast, see page 17.)

Check the operation of the winding lever safety
latch. When the shutter is not set, the winding lever
must be locked in the unwound position. After the
shutter has been actuated with the winding lever,

the winding lever must return fully and become
locked in the unwound position.

The flash settings on the shutter should be
timed with reliable shutter testing equipment. The
tolerances of the delayed action in the shutter for
synchronization with the flash bulbs are as follows:

F (short stroke)* 3 1/2—5 1/2 milliseconds
M (long stroke)* 12 — 16 milliseconds

♦From instant of contact until the shutter blades

first begin to show light.

.005 inch clearance between the contact
lever tail and that part of the trigger latch
which engages the tail. The contact points
must be in contact. If there is no clearance
or if there is excessive clearance, the
spacing may be controlled by bending the

contact lever tail in or out.

Allow the winding lever to go to the “at

rest” position. Depress the trigger and

watch to see that the flash contacts do not
close. If they close, hold the end of the con
tact lever tail toward the shutter case,
place a screwdriver blade against the verti
cal position of the contact lever tail near the
contact lever stud, and apply pressure to

ward the shutter blades at this point.

With the shutter tripped, there must be
approximately .005 inch clearance between
the contact lever latch spring lug and the

side of the contact lever. This is to assure

fullpressure of the latchintothe star wheel.

While pressing the trigger down fully,
watch the contacts to make sure they do not
close at any time. If they close, the con
tact lever tail on the contact lever has been
bent too far and it should be moved back
slightly. If necessary, the winding lever
should be stoned at point “A ” figure 10.
Corner “B” must be square.

operate freely.

7. Open the shutter blades. Close the dia

phragm wings and run the side of a screw
driver blade around the central opening in
the mechanism plate. This will open the dia
phragm wings uniformly to the maximum
aperture.

8. The shutter CASE, figure 23, diaphragm
POINTER and the SETTING LEVER should
be thoroughly cleaned. Apply a thin film of
grease (Texaco Unitemp-RCX169 Grease) in
the recess in the case occupied by the set
ting lever. Then wipe this area lightly with
a clean cloth.
