a mlnImum of play between the gears. If there is
excessive play or binding of the gear teeth move
the focusing scale bracket until the condition is
corrected. Then remove the pinion from the post.
Place the anti-back lash gear (figure 17) over
the gear on the cam
assembl~e
sure the anti-
back lash gear fits tight against the cam assembly
gear. If it does not fit tight, ream out the hole in
the anti-back lash gear. Check for burrs on the
gear by turning it on the cam assembly. Set the
anti-back lash gear spring over the anti-back lash
gear with the center loop of the spring over the
end of the cam assembly shaft. Fit the short end
of the spring against the protruding end of the anti-
back lash gear and the long end of the spring against
the gear and the cam assembly. Secure the spring
in position with the spring holding screw. Turn the
anti-back lash gear against spring tension (counter-
clockwise) until three teeth of the anti-back lash
gear extend beyond the first tooth on the cam as-
sembly gear. Set the pinion on the post and mesh
it
with the teeth on the cam and anti-back lash gear.
-Attach the focusing dial (figure 18) to the focus-
ing scale pinion with the holding screw. The com-
pleted focusing dial reassembly is shown in figure
19. Set the direct view finder cover on the range
finder plate and check to make sure the focusing
dial operates smoothly and that the dial is centered
in the depth-of-focus scale frame window. Then
lift off the finder cover and remove the focusing
scale and holding screw. Replace th~ parallax
frame assembly and the range finder eyelet lens
assembly and fasten them with the two range finder
eyelet frame screws. The eyelet lens assembly
should go on first with the frame toward the rear;
make sure that it is straight and that it is pushed
as far toward the front of the camera as it will go.
Extend the focusing tube and make sure the anti-
back lash gear does not strike the parallax adjusting
screw. If it does, file off the corner which strikes
the screw.
In removing the right end prism assembly from
the old style cam follower assembly and replacing
_ it on the new style cam follower assembly, the range
finder may be moved out of adjustment. For adjust-
ments to the range finder see page 16 .
Set the range finder on infinity by looking at an
object at least 200 feet away. Then replace the
focusing dial on the pinion with the infinity indica-
tion facing toward the front of the camera. Secure
the dial in position with the holding screw. Set the
direct view finder cover on the range finder plate
and fasten it with the four retaining screws.
To adjust the focus of the lens refer to page 22.
CAMERA CASE AND ASSOCIATED PARTS .
TRIPOD NUTS (See figure 11).
If the threads have been stripped from one of the
tripod nuts, remove the bottom plate as described
on page
6.
NOTE: It is not necessary to remove
the shutter, focusing tube, or focusing
tube guide.
Using a punch with a head approximately 1/32
inch in diameter, knock out the old tripod nut from
inside the case. To do this, rest the case on a
block of wood with a hole slightly larger than the
tripod nut drilled in it.
Place a new tripod nut in position, and with the
case resting on a flat metal block, turn over the
flange which holds the tripod nut in position. This
is conveniently done by using a screwdriver with a
blade about 1/8 inch wide, ground down so that the
end is about 1/32 inch thick.
FOCUSING TUBE ASSEMBLY (See figure 9).
If the inside focusing tube binds in the outside
tube, smear the inside focusing tube with any light
oil and sprinkle powdered graphite liberally over it.
Worktthe inside and outside tube together until
they turn freely, starting the inside tube on different
threads of the outside tube.
Clean off the parts of the focusing tube assembly
with carbon tetrachloride and reassemble. The
same procedure can be followed if the outside focus-
ing tube binds on the focusing tube insert.
WARNING: Carbon tetrachloride is a
volatile solvent. Use it with adequate
ventilation. A void frequent or prolonged
breathing of the vapors.
MECHANISM PLATE.
The following repairs to the mechanism plate
assembly (figure 7) can be made only with the mech-
anism plate removed from the camera.
SHUTTER SETTING BLADE ASSEMBLY
(See figure 1).
If the shutter setting blade assembly is bent and
is binding, remove the guide rod clamping screw
(figure 7). With a jeweler's screwdriver, break
the upper guide rod (figure 1) loose at the clamp
screw end and push it out through the holes in the
mechanism plate.
Remove the three shutter setting blade stud nuts.
Then remove the range finder actuating lever link
nut and the, range finder actuating lever link washer
on the end of the shutter setting blade assembly
