Repair manual

through, it is necessary to replace 071 slides and possibly 503
gear. Mark 551 gear, 503 gear, 534 gear, if possibly 503 gear.
Mark 551 gear, 503 gear, 534 gear, if not already marked.
Remove lock ring and 551 gear. Unhook back 212 spring at frame
and unhook front 212 spring at 071 slide. Loosen top set screw
in 515 film sprocket. Pull out 503 gear, 071 slides, 215
sprocket sleeve, and 075 sprocket spring. Remove 075 spring
and 215 sleeve from gear. Remove 212 spring from 071X slide
and replace on new 071X slide. Place new 071X slide on top of
new 071Y slide (Both ears up), then place both slides over
shaft of old 503 gear, with ears towards gear. Place 215
sleeve (Flange toward gear) and 075 spring over shaft of 503
gear. Holding 075 spring in place, place gear, slides, and
springs in camera. Align marks on 503 and 534 gears and hold
gear in place. Hook back 212 spring to frame, this should hold
gear in place. Hook front 212 spring to 071Y. Turn 503 gear
so that studs are at right angles to back of frame and cock
movement by turning 515 sprocket. Place a 020” spacer between
503 gear and top back edge of frame and hold gear down tight
against spacer. Turn 515 sprocket so set screws are facing
back of camera. Line up center line of tooth (515 sprocket)
with center of camera and tighten upper set screw. Check to be
sure that the center line of the tooth is in center of camera.
This is very important. Replace 551 gear and lock ring, be
sure gear goes back properly. Retest winding in both “A” and
“B” positions. If camera winds through, it may be necessary to
replace 503 gear in which case repair as follows: Same
instruction except the flash wire may have to be taken off the
stud above the 534 gear and the 534 lifted and turned to find a
place where they will turn together smoothly (Without feeling
the gear teeth). Replace top. (Section 21.200)
2.500 Loose Set Screw
This is very unusual, but if a camera comes in stating “Defective
Shutter or Winding,” it may be due to a loose set screw in 515 film
sprocket. See section above (2.422) for aligning instructions.
Tighten set screw.
3.000 TOP
3.100 Sticky Exposure Dial
3.110 Check to be sure the speed and aperture dial are not interfering
with the operation of the exposure dial. If it is, you can
correct this by slightly bending up on the exposure dial.
3.120 If the exposure is free from outside interference it will
require removing top to repair. Remove bottom and back (Section
20.100) and top (Section 21.100).
3.130 Disassemble as follows: Remove light seal, Viewfinder lenses and
Cam Follower 118-517.
3.140 Check to be sure the pinion 118-545, and the exposure dial turn
perfectly free. If not, remove screw on top of the exposure
dial, remove exposure dials, washer, and pinion. Burnish hole a
little with a .1251 diameter dowel pin, using a little
lubricant. Clean hole with a pipe cleaner and reinstall pinion
and dials. Be sure to engage 118-055 “Simmer-Winter” dial in
