54. RANGE FINDER THEORYOF THE KODAKCHEVRON
CAMERA
The optical system in this range finder is very similar
to that in the Kodak 35 Range Finder Model, except that
the range finder viewing window is moved over to a point
directly beneath the view finder window. This is accom-
plished with two additional mirrors (in the range finder
cover) whose only function is to position the range finder
images on the view finder axis. Fundamentally, therefore,
the range finder consists only of the two large mirrors on
the camera body. (Figure A).
The Kodak Chevron range finder has been designed to
show a blending of the two images rather than the more con-
ventional sharp division. It is, therefore, impossible to
obtain a sharp line between images without sacrificing
other desirable characteristics of the range finder field.

SERVICE MANUAL NO. 5510-A
53. Place the shutter release in the socket and replace
the shutter trigger release screw. (See Instruction No. 59
to refocus the lens.)
In a correctly adjusted range finder, the upper and lower
images wi II appear offset in the manner shown in Figure C.
The principal characteristics of a well adjusted range
finder are:
A. Equal offsets in the directions indicated.
B. An aligned vertical line through the pointer of the
range finder field should also be in the center third
of the view finder field. (See Figure D).
C. Upper and lower range finder fields of approximately
equal heights.
D. The range fi nder field should be parallel to the view
finder fiel d.
E. The pointer should be located in the center of the
upper range finder field.

VERTICAL
TARGET
LINE
Figure D
It
is recommended that suitable focus charts be made
and
located at 3.5 feet and 15 feetfrom a fixed camera lo-
cation. Distances should be measured accurately from the
film plane of the camera, and the charts must be mounted
so as to be centered on, and perpendicular to, the optical
axis of the camera.
It has been found that a triangular focus chart wi th a
vertical line added at the center, is sufficient for checking
and adjusting the range finder.
56.
RANGE FINDER FUNCTIONAL ADJUSTMENTS
Functional adjustments to the range finder concern
mirrors No.1 and No.2 only (Figure A) and should be
made before
attempting any others. These must be made
after removing the range finder top housing by the following
procedure:
Set finder frame control on "828", remove ex-
posure counter dial, then remove the two screws located in
the top of the spool recesses.
It is possible to make these adjustments with the un-
aided eye but the di stance from the eye to mirror No.2 and
the
position of the line of sight relative to the stationary
mirror are rather critical. Tool No. 778 is a top ho~sing
provided with an aligned viewing tube and cutouts for
most
of the adjustments. Its use is recommended and is
presupposed in the instructions which follow.
Range Fincler Tolerance (See Figure E)
Maximum permissible scale error either side of the scale
pointer is .6 of the distance A at the 3.5-foot setting,
and .4 of the distance A at the 15-foot setting. Align-
ment at infinity should oCCur when some part of the mark
"INF" is opposite the pointer.

1. Train the camera on an infinity object (preferably
vertical) and rotate the focusing ring to the INF
stop. Adjust the movable mirror screw with Tool

to align the images; in to move upper image
to the right (tool No. 778 in place).
2. Train the camera on the 3.5 foot chart and align
the images by means of the focusing ring. If the
3.5-foot mark is not within tolerance, proceed as
follows:
(a)
( b)
(c)
Turn the movable mirror adjusting screw about
one full turn; in if the 3.5 foot mark is to the
right of the index mark (tool No. 778 in place).
Rotate the focusing ring to the INF mark and
align the images of an infinityobject by loosen-
ing the two stationary mirror mounting screws
slightly and rotating the mirror bracket. (It
wi II be necessary to remove tool No. 778 in
order to reach these two screws.)
Check at 3.5 feet and repeat step No. 2 untiI
both
readings are within tolerance.
3. Check the range finder for correct reading on the
15-foot chart, and if not within tolerance repeat step
No.2, as necessary, unti I the 3.5, 15 and INF
readings are all within tolerance.
4. Seal all adjusting screws with Vulcolac, or equiva-
lent.
AcI;usting Halving
Halvingis within tolerance if the two sides ofan aligned
triangular chart l,ine up.
To raise the upper image, turn the stationary mirror
adjusting screw in (tool No. 778 in place).
AcI;usting Pointer in Upper Fielcl
The pointer is correctly adjusted if it is in alignment
with the properly focused vertical line of an accurately
positionea chart. (See Instruction No. 55.)
To adjust, loosen the two screws of the pointer bracket
and slide it either direction until the pointer is in proper

alignment. A change of pointer position will require re-
adiusting the footage. Seal screws with Vulcolac, or
equivalent.
(It wi II be necessary to remove tool No. 778
in order to reach these two screws.)
Masking of Upper Field
The upper and lower fields should blend with each
other, rather than have a sharp division. The bottom
edge of
the upper field should also be parallel to the top
edge of the lower field.
Correction is made
by means of the slide located on
the pointer bracket which must be sealed after any ad-
justing.
(It wi II be necessary to remove tool No. 778 in
order to reach the slide.)
57. RANGE FINDER APPEARANCE ADJUSTMENTS
The principal characteristics as described in In-
struction No. 54 are determined somewhat by the function-
al adjustments made to the range finder, but
are mainly
determined
by the appearance adjustments. Therefore, it
is important that any corrections for appearance be
made.after it has been determined
that the range finder
is functioning properly. The various adjustments
listed
here are all made to the two mirrors located in the range
finder cover
(No.3 and No.4, Figure B), and it is nec-
essary to use the cover that wi II be assembled to the
camera.
Each
01 the mirrors has a primary and secondary effect
on the appearance of the range finder fields, and some
balanci
ng between the two wi II be necessary. Since it
may be
necessary to remove and replace the cover sev-
eral times while adjusting, it is recommended that two
of the cover screws (part No. 126202 and No. 126203)
be altered,
as shown in Figure F, tobe assembted in the
cover as guide pins.
Offset Adjustment
The upper and lower fields should appear offset sub-
stantially the 'same distance in each direction as shown
in Figure C.
The position of the upper field
in relation to the
lower field
is changed by bending the large (No.3)
mirror about a vertical axis. Secondary effect: Changes
the position of
the upper field in relation to the view
finder field.
Position Adjustment
An aligned vertical line through the pointer of the
range finder field should also be in the center third of
the view finder field.
The position of
the range finder fields in relation to
the view finder field
is adjusted by bending the small
(No.4) mirror about a vertical axis. Secondary effect:
Changes the- position of the upper range finder field in
relation to the lower range finder field.
It is reconmended that offset and position adjust-
ments be alternated until both characteristics aresatis-
isfied.
SERVICE MANUAL NO. 5510-A
Height ancl Blencling Acljustment
The upper and lower fields shou Id be of approximately
-equal height and
also should blend together rather than
have a sharp division between them.
The height of
the upper field in relation to the lower
field is changed
by bending the large (No.3) mirror about
a horizontal
axis. Secondary effect: Tilts the upper
field.
Tilt Adjustment
The range finder field should be parallel to the view
finder field.
The
tilt of the range finder field in relation to the
view finder field
is adjusted by bending the small (No.4)
mirror about a horizontal axis. Secondary effect: Changes
height of upper field in relation to the lower field.
It
is recommended that height and blending and tilt
adjustments be alternated unti I both characteristics are
satisfied.
Pointer Acljustment
If the pointer has been adjusted as described in In-
struction No. 56 and the other characteristics corrected
as previously described, no further adjustments to the
pointer will be necessary.
58. FITTING SPORTS FINDER CLIP
On cameras above Serial No. 3400, the three holes for
accepting
the finder shoe are pre-drilled and tapped.
These holes are directly to the rear of the name plate,
and covered with the leather covering.
On cameras below Serial No. 3400, it wi II be neces-
sary to drill and tap the holes. The finder shoe supplied
with the Kodak Chevron Sports Finder Kit can be used
as a template by holding it in correct mounting position
while drilling with a
No. 50 (.070) drill. Tap the drilled
holes with a
No.2-56 (R.H.) tap.
59. ADJUSTING FOCUS
Check the focus on a 15' chart. Use ground glass
with the ground side toward the lens and on the film rails
of the back frame. Turn the focusing ring until the lens
is focused
for best definition in the center of the picture
area. Loosen
the three screws on the focusing collar and
align the 15'
scale reading with the index mark without
turning the focus ring
(see Instruction No. 31).
