INTRODUCTION
This section on the Graflex Service Parts Manual
covers the Service Instructions and Parts List for
the Super Graphic and Super Speed Graphic Cameras.
The text and illustrations are based on the Super
Graphic Camera. The differences between the Super
Graphic and the Super Speed Graphic are clearly de-
scribed in the Parts List.
A. CAMERA COMPLETE
The Super Graphic Camera (Figure 1) includes a
camera basic, standard shutter (with lens) mounted
in a Super GraphiC Lensboard Assembly, matching
lens cam and a set of infinity stops to match the
focal length of the lens.
The Super Speed Graphic Camera is identical to
the Super GraphiC except, the Super Speed Graphic is
equipped with a Graflex 1000 Shutter. The Graflex
1000 Shutter does not require a lensboard for mounting.
NOTE: The lens cam is selected after the
lens has been optically measured
for actual focal length (lens travel).
B. OPTICAL MEASUREMENT OF LENS TRAVEL
Optical measurements are best determined through
the use of a collimator with an accurate measuring
device. Lens is set up and focused on theoretical
infinity and the measuring device set for O. Lens
movement is measured (to nearest. 001 of an inch)
from infinity to the following near distance:
Lens Focal Length
3 to 7 inch
7 to 15 inch
Near Distance
(target to film plane)
4 feet
10 feet
At least three different readings should be taken and
recorded to insure that a satisfactory figure has been
obtained. If equipment is not available, send lens
and shutter to nearest Graflex Service Department
for collimation and selection of cam.

The rangefinder is mounted in a drawer type hous-
ing" located under the top section of the camera.
Once the rangefinder is adjusted, it can be used with
a wide variety of lenses through the use of lens cams.
Lenses may vary in focal length from wide angle
through telephoto.

Rangefinder Operation
SUPER GRAPHIC & SUPER SPEED
Section 8
D. RANGEFINDER OPERATION (Figure 2)
To adjust the rangefinder, it is important to under-
stand its operation. A bracket on the left side of the
bed yoke engages a slide. The slide is assembled to
a pin located on the underside of an external plunger.
The slide and plunger are part of the rangefinder
tube assembly. The external plunger transmits its
motion through a column of balls and spacers inside
the rangefinder tube to an internal plunger that pushes
the lens cam to the right. The lens cam presses
against a spring loaded plunger supplying force to
return the lens cam to its original position when the
yoke is moved outward.
The bed yoke is moved in or out for focusing. The
rangefinder arm rides on the lens cam; motion of
the arm, caused by the cam, is transmitted to the
movable mirror shaft. The rangefinder lever also
rides against the formed end of the rangefinder arm
transmitting its motion to a gear sector which meshes
. with a pinion. This linkage is spring loaded against
the formed end on the rangefinder arm by a coil
spring wound to this pinion shaft. The shaft of the
pinion protrudes through the top of the camera. An
indicator is pressed onto the pinion shaft when range-
finder infinity has been established.
The image reflected off the movable mirror can be
brought to coincide with the image seen through the
stationary semi - transparent mirror by rotating the
movable mirror. When these two images are in co-
inCidence at the same time that the object image seen
through the lens is in sharp focus on the ground
glass, the rangefinder and camera lens are in com-
plete synchronization.
E. RANGEFINDER INFINITY
Rangefinder infinity is determined through the use
of a collimator and using theoretical infinity. Special
optical equipment and gages are required for locat-
ing and alignment of the movable mirror . When these
adjustments have been accomplished, the locking
screw on the rangefinder arm is tightened to main-
tain this fixed infinity setting. This locking screw
should not be loosened. See Par. K for ran g efinders
requiring fixed infinity settin g.
F _DOUBLE IMAGE ADJUSTMENT
1. Remove battery cover and batteries.
2. Remove clip and locate the lock spring on roof
of battery compartment and swing toward rear of cam-
era. This will release the focusing scale cover as-
sembly.
3. Remove the exposure guide and exposure guide
spring. When performing this operation be careful
not to bend or twist the focusing scale indicator on
the pinion shaft, otherwise it will be necessary to
replace the indicator.
4. Remove the lens cam; this in turn will allow
the
focusing scale indicator to swing clear of the fo -
CUSing scale plate.
5. Replace the lens cam in slot in rangefinder tube.
6. With a screwdriver, locate slot in adjusting
screw (located under hole) in uncovered portion of
the camera body. To raise image, turn adjusting
screw counterclockwise. To lower image, turn ad-
justing screw clockwise.
G. ACTUATING BRACKET ADJUSTMENT
Whenever the rangefinder housing has been re-
moved from 'the camera or the actuating bracket is
being replaced or repositioned, the following p"o-
cedure should be followe'd:
1. Insert lens cam incam slotinrangefindertube
assembly and move the yoke inward and outward
several times to make sure lens cam is in position
and functions properly.
2. Focus rangefinder on infinity target over 5000
ft. and rack the bed yoke inward until it is within
0.040 ±. 010 inch from the yoke stop and lock bed
yoke in this position.
N.OTE: It is importantthat 0.040 ±. 010 dimen-
sion be maintained in order that all
focusing may be accomplished with a
forward movement of the bed yoke.
Slide the actuating bracket on the bed yoke until the
formed down portion of actuating bracket engages
the slide. Focus rangefinder on infinity target and
Simultaneously move actuating bracket on bed yoke
until rangefinder focus is in coincidence with the in-
finity target. Secure actuating bracket in this position
using two screws. If rangefinder housing has been
removed, press new indicator in position on pinion
shaft so that indicator will pOint to infinity (00) lo-
cation on focusing scale plate. Apply small amount
of M373 Bond Master adhesive in cup portion of indi-
dlcator to give added support.
3. Assemble the front standard complete, if re-
moved, and proceed with lens and rangefinder syn-
chronization(Par. H).
H. RANGE FINDER AND LENS SYNCHRONIZATION
Use lensboard assembly (with lens) and lens cam
which were originally fitted to the camera and pro -
ceed as follows:
1. Rack bed yoke outward and install lens cam in
canl slot in rangefinder tube. Rack bed yoke inward
and outward severaL times, m~king sure that cam is
in position and functions properly.
2. Focus rangefinder on infinity target over 5000
ft. and check rangefinder infinity focus. Lock bed
yoke in this position. The indicator on top of camera
should point to infinity (00) position on focusing scale
plate. If necessary, make double image adjustment.
3. Position lensboard assembly (with lens) in front
standard making sure lensboard is square in front
frame and securely locked in place.
4. Pull front standard out to existing infinity stops
and lock front standard in this position. Use a
square to check squareness of front standard on bed
yoke. Adjust if necessary.
5. Check ground glass focus of lens, using same
target as in 2 above. If rangefinder and lens focus
coincide; unlock bed yoke and rack forward to near
distance of the lens used, lock bed yoke in this
positi.on and recheck coincidence. If in coinCidence,
proper rangefinder and lens are in complete synchro-
nization.

Multiple Lens Fitting
J. MULTIPLE LENS FITTING
Before additional lenses are fitted to the camera,
it must be determined if original lensboard assem-
bly (with lens) is in synchronization with the range-
finder.
1. Repeat Rangefinder and lens synchronization
(Par. H).
2. Rack bed yoke outward and remove original
lens cam and lensboard assembly (with lens) and
insert lens cam for new lens to be fitted. Rack bed
yoke inward and outward several times, making sure
cam is in position and functions properly.
3. RaGk bed yoke inward to infinity position of the
rangefinder and lock bed yoke in this position. The
indicator will point to infinity (00) position on focus-
ing scale plate.
4. Position new lensboard assembly (with lens)
in front standard making sure lensboard is square
and securely locked in place.
5. Tip down infinity stops (original) to permit
free movement of the front standard on the bed yoke.
6. Focus new lens on infinity target over 5000 ft.
and move front standard so that lens focuses a sharp
infinity target on ground glass and lock front stand-
ard in this position. Use a square to check the
squareness of front standard on bed yoke. Assemble
two additional infinity stops in position.
7. Check ground glass focus of lens, using same
target as in 6 above. If rangefinder and lens focus co-
incide, unlock bed yoke and rack forward to near dis-
tance of the lens used, lock bed yoke in this position and
recheck coincidence. If in coincidence; proper range-
finder and new lens are in complete synchronization.
K. RANGE FINDER HOUSING EXCHANGE
Whenever the fixed infinity setting of the range-
finder needs to be established, it is recommended :that
the rangefinder housing assembly be removed from the
camera and returned to the nearest Graflex Service
Department. An alternate factory reconditioned range-
finder housing assembly will be returned (nominal
charge) with rangefinder infinity and lever adjustments
accomplished and ready for installation. See Par. S.
1. a thru j for removal of the rangefinder housing as-
sembly.

N. SUPER GRAPHIC ANALYZER -GENERAL
The Super Graphic Analyzer is a special piece of
testing equipment that includes provisions for check-
ing all electrical functions ofthe camera. This equip-
ment will help isolate trouble areas within the electri-
cal circuit of the camera, with minimum time and
effort. The test function chart, mounted on left side
of the instrument, lists: switch positions, electrical
circuit being tested, and indicator reading to be main-
tained at each switch position.
The Super Graphic Analyzer contains three sources
of power supply, controlled by the selector switch as
follows:
Positions 1 thru 5 - 500 volt power supply is
used to measure high resistance leakage, open
and short circuits.
Positions 6 thru 8 - 5 volt power supply is used
to measure low resistance circuits and conti-
nuity.
Positions 9 and 10 -45 volt power supply is used
(simulating batteries normally used in camera)
to test electrical leakage of capacitors.
