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

Note: Numbers in parentheses in the text correspond to circled numbers

on page 6. Disassemble in normal order and reassemble in reverse

order.

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.
