movement plate, or some other interference with the 522 reset
lever. Increase clearance by very carefully prying up on
movement with screwdriver. Test for freeness by sliding 522
reset lever back and forth.
2.220 Main Lever Hour Glass Cam Alignment
If winding knob turns free for about on half a turn, then binds
and will not go further, but will reverse, it may be caused by a
mis-alignment of the 506 main lever and 523 hour glass reset cam.
The main lever rides around the contour of the 523 hour glass
reset cam, which cocks the movement. However, the binding is
caused by the main lever slipping off the edge of the 523 hour
glass cam. With winding knob in normal position and the shutter
released, pull the 522 hour glass cam away from the center of the
camera and hold there. Looking through the large hole in the
center of the movement plate, you see the 523 hour glass cam, and
the main lever. If the main lever is lower than the 523 hour
glass cam, very carefully, bend it up with a screwdriver. If it
is higher, bend it down. Test by winding the camera faster than
normally in both “A” and “b” positions.
2.230 Tight 510
If the winding knob binds in “B” position only, it may be due to
and exceedingly tight 510 pawl assembly. If this is the case,
follow the instructions in section 2.110. If any of the large
gears (503, 534, or 551) are removed, be sure to mark, so as to
replace in same position in relation to one another.
2.300 Winding knob will not lift
When winding knob will not lift to change setting, it will usually
work on every other number. When changing setting you find the knob
will not lift, release and wind shutter once and then change
setting. This time it will work all right. If customer will stand
this inconvenience, no repair is required. If repair is needed,
remove top according to instruction. (Section 21.100) mark 503
large center idler gear and 551 thick lock assembly gear so that
they can be put back the same way. Remove lock ring from stud above
551 gear. Remove 551 gear and file off .005” or .006” off bottom of
the hub of 551 gear. This will lower gear. Clean off gear.
Relubricate hold in gear hub if necessary. Replace gear and lock
ring. Replace top according to instructions. (Section 21.200)
2.400 Winding Knob Will Not Lock
There are two conditions (A) Camera will not lock in “1” position at
end of “A” before shifting to “B” and (B) Camera will not lock after
on complete winding cycle.(Exposure)
2.410 Will Not Lock In “1” Position
This condition is very unusual. First check to be sure the
winding knob is not loose. Turn selector knob to “A” and wind
and release shutter 45 times to see if knob will lock at another
position. If so, the 261 exposure counter dial may have slipped
on knob or someone may have removed knob and replace it
incorrectly. The shaft is spot drilled so the set screw will not
slip on shaft. There are two set screws – One on top of the
other in winding knob. If knob does not lock at all, it will
require replacing 551 gear or 500 shaft or both. This should be
done at factory if at all possible.
