Introdu tion
The NEW F-1 is the base of a completel new Integrated Functional S stem. It is based on
the original F-1 but utilizing man advances in electronics, precision machining and precision
optics made since the original F-1 was developed ten ears ago.
The following considerations should be kept in mind when repairing the New F-1:
1. To maintain complete interchangeabilit between the camera bod and the s stem
accessories, repair personnel must understand the interfaces (mechanical
and electronic) between the bod and accessories. The must also be familiar with
repair standards, checking, adjustment and tools maintenance procedures.
2. Preventive maintenance (lubrication, adjustment and parts replacement) are
necessar to insure the reliabilit of the NEW F-1.
Spe ial Repair Instru tions
1. Man of the electrical contacts in the camera are molded into plastic insulators.
When making solder connections, the soldering time should be kept as short as
possible.
2. 3% silver solder should be used to solder the IC's.
3. Man bearing balls are used in the winding mechanism. Be careful during assembl
and disassembl to insure that no balls get lost in surrounding mechanisms.
4. When the rewind crank is not installed, if the rewind shaft is pushed down past a
certain point it becomes impossible to open the back cover without removing
certain parts that normall need not be removed. This results in lost time.
5. Be sure that the elastic connectors used to connect the flexible and rigid circuit
boards are kept clean and free of contamination.
6. The water and moisture proofing complicates man repair procedures. Take care
that the are correctl performed
7. If the tungsten cable is kinked or fra ed, repair is difficult and time-consuming. It is
much more cost efficient to be careful to not damage the cable than to repair or
replace it.
8. The correct adjustment of the AV AE shutter speed indicator output resistor (RM
TV2) and the TV AE aperture determination resistor (RAE) are basic to maintaining
s stem interchangeabilit .

Disassembly Notes Assembly and Adjustment Notes
1. Remove the smooth face screw (3)
and shutter button (6) with tool
(CY9-6131-000).
2. Be careful not to lose detent
ball (7)-2 inside the camera.
3. The shutter dial cap (9) is glued in place.
4. Seals (8)(14)(29) and (30) are
available in more than one thick
ness to insure correct sealing.
5. When the rewind crank (22) is not
installed, don't push the rewind
shaft all the wa down into its
holder. (If it is, time will be
lost in unnecessar work, because
of the click spring.)
6. Press the opening safet stopper
while removing the left top cover
7. (35).
Assembly and Adjustment Notes
1. Put Diabond into the winding
lever shaft hole before final
installation of the screw (3).
2. Lubricate the shutter button
shaft (6) and the interior or
the release lock (7) with GE-C9
[See Water-resistant treatment
(XIX)].
3. Put Lozoid in the detent groove
of the release lock (7).
4. Place teflon washer (8) under the lock lever
(7). Use a washer that is 0.3mm thicker than
the "A" dimension shown below. (Water
resistance)
A = l.l-(a-b) mm
Washer t = A +0.3mm
5. The teflon washer (14) used under the shutter
dial should be 0.1mm thicker than the "B"
dimension shown below. (Water resistance)
B .= 0.5-(a-b)
Washer t = B +0.1mm
6. When installing the shutter dial, align the notch
in (15) and the pin in the shutter dial ring (13)
with the hole in the top cover. The shutter
must be set to "A" before the dial is installed.
Note: Numbers in parentheses in the text correspond to circled
numbers one page 6. Disassemble in normal order and reassemble in
reverse order.

Assembly and Adjustment Notes
7. Adjust the rewind crank (22) slip torque b changing the friction washer (21).
Torque Limits: 35 to 55 gcm.
8. Lubricate both sides of friction spring (20) with PL-015.
9. Hold the rewind fork. Raise the rewind crank knob and turn in
the rewind direction. The clutch should engage within one half
turn,
10. To install the ASA Dial, set the SV wiper wiper pin as shown and align the "1/2"
on the exposure compensation dial with the index.
11. Check the difference in height between the rewind crank bushing and the "A"
and "B" surfaces. Install a slightl thinner washer as indicated below.
11.1. Washer (30) "A" Difference Check at four points.
Ex: Difference Washer "t"
0.15mm --- 0.1mm
0.2mm --- 0.2mm
0.1mm --- No washer
11.2. Washer (29) “B” Difference
Ex: Difference Wacher “t”
0.55mm --- 0.5mm
0.4mm --- 0.4mm
0.35mm --- No washer

Assembly and Adjustment Notes
12. SV Brush Adjustment
12.1. Set the SV (ASA.) dial to ASA 6400 -1/3.
12.2. Set the exposure compensation dial at "1".
12.3. Check the position of the brush through the P.C. terminal hole.
Note: Shining the light source (a penlight or the illuminator D or M) through the
loupe makes the brush position easier to see.
12.4. Look at the underside of the SV board to check if the brush
if the brush is positioned as shown on the ASA 6400 -1/3 pad.
Note: It must sta on the pad at both extremes of dial pla .
12.5. Set the dial to ASA 6400 and check that the meter doesn't
var suddenl either up or down.
12.6. If the adjustment is not correct adjust the SV board eccentric.
13. After installing the top cover (35), check the operation of the NORMAL-TIMER-LAMP
switch.
It should switch from one function to the next as shown.

(6), unsolder the black lead from SW4
and remove four screws [(6)-1 x 2 and
(6)-2 x 2].
Notes:
1. One of the (6)-1 screws is partiall
hidden b flex (5) and hard to remove.

where the cable will remain taut and
not become kinked.
2. Mounting screw (9)-2 for the winding
base is under main switch (8).
3. The entire 2nd curtain brake assembl
(17) can be removed without
disassembling it b removing three
screws (15) and collar (16). Disengage
the brake lever from the
master gear and (17) can be removed.
Assembly and Adjustment Notes
1. The shutter speed selector (6) TV double
brushes must be aligned both verticall
and radiall , so the will both make
contact with the correct pad.
2. Clean the TV resistor board (2) and install
it so that break in the pattern is at the
upper right with the shutter at "A".
