REPAIR INSTRUCTIONS
1.000 SHUTTER
The vast majority of all shutter repairs may be made by lubricating
RATCHET wheel with “DAG 154” as described in this section (1.110 and
1.310). “DAG 154” is colloidal graphite diluted in ALCOHOL (1 part
DAG to 7 parts alcohol). Acheson Colloidals Co., Port Huron,
Michigan, U.S.A. If shutter does not open, check to be sure winding
cycle is completed. If it is not, see section B “Winding.” Do not
oil shutter blades or movement. “DAG” the ratchet wheels on all
cameras repaired that have not previously been lubricated.

1.100 Shutters stick open when wound
This will cause blank clear pair on roll. Remove bottom and back.
1.110 Sticky Ratchet
Check to be sure RATCHET is working freely by holding release
button down and winding camera. Operation of escapement must be
smooth. If escapement is rough, lubricate #520 ratchet wheel
with “DAG.” Check 520 ratchet gear and 509 gear sector for end
play (MAX. 1008”). If escapement is still not working smoothly,
it may be necessary to replace the 520 RATCHET wheel.

1.120 If escapement is working freely, check the following and repair
accordingly:
1.121 Latch Engagement
The shutter must pick up the 082 primary latch. If it is not,
bend ear of shutter blade so it will pick up latch. Do not
over bend shutter ear as it will cause excess friction on flash
switch. If shutter ear is broken off, remove front, replace
shutter blade, reassemble and reinstall front. (See
instruction “Replace Shutter.” 22.200.)

1.122 Overtravel Pawl:
Turn selector knob to “B” position. Release shutter and wind
slowly. You will note that the 082 primary latch is picked up
by the shutter blade and towards the end of the winding cycle
as the latch is pulled back, it allows the 084 primary pawl to
engage with the 082 latch and thus holding it in position.
After the 082 latch and 084 pawl have engaged, the 082 should
continue to move back and should have a minimum of .010”
overtravel between 082 latch and 084 pawl. If overtravel is
not correct, bend 522 lever assembly ear away from release
button to increase overtravel. Care must be used not to bend
522 lever too far. Retest in “B” position, then turn to “A”
position and retest. The 522 lever must not be bent so that it
will bend the shutter blades at the end of it’s stroke.
Recheck.

1.123 Tight Pawl
Check 084 pawl for freeness, If it is sticky or tight, very
carefully press down on 084 pawl to get end play between 096
movement plate and 084 pawl, then lubricate with “DAG” 154.”
