Picture frame
The position of the picture frame of the magazine,
i. e. the distance between the edge of the picture
frame and the outer plate is inspected and adjusted
using the magazine gauge V- 4548. The distance is
Lubricate with grease (Fig. 4). Fit the release arm
22277. Lubricate the gears and shafts of the
centre mechanism 21548 with some drops of oil
and fit it over the pin (A Fig 4).
Fit the gear 22371 and bring the centre mechanism
into the hub of the magazine support. Fit the spring
816611 into the spacing gear. Tension the spring by
rotating the gear clockwise approx. 1 1/2 turns.
Turn the spacing gear towards the stop and check
that it returns properly (to Zero).
Fit the arm 22715. Lubricate the shaft 12819 with
grease and assemble it. Connect 2 springs 814527 to
the pin (A Fig. 4).
On the centre mechanism there are 2 springs,
connect them to the screw 824060 and link 21494
respectively. Fit the dial 13806 over the spacing
gear. Secure with 3 screws 824202, do not tighten
the screws too hard (Fig. 5)
Fit the return stop 20717 together with washer
810802 and secure it with clip 817132.
Fit the spring 14184 in the spring housing as shown
in the diagram. The easiest way to do this is to use a
new spring kept in its plastic ring, then lubricate the
spring with grease (Fig. 6).
Fit the hub 14185 into the spring and assemble back
the spring housing on the magazine support.
Lubricate the gear assembly 308109 (Fig. 7).
Tension the spring 14184 by rotating the spring
housing 13030 clockwise approx. 1 1/2 turns,
hold in place and fit the gear assembly (Fig. 8).
Conduct the shaft 308426 through gear 308109.
Note! The long pin has to go down into the magazine
support. Fit the gear 12209, insert washer 810926
over the centre mechanism 21548, fit the plate
308485 and secure with 2 screws 823012.
Fit the washer 810927 over the plate. Tension the
spring 816509 approx. 1 turn and fit the film signal
13031.

Adjustment of automatic stop
Press the pin 13754 in with a finger and rotate gear
12209 clockwise on until release arm 22277 falls into
the first recess under gear 22371.
At the same time this takes place the stop on plate
308485 has to fall into the recess on dial 13806. This
relation will be adjusted by turning the dial. When
the correct position is reached the screws 824202
shall be tightened and secured with safety lacquer
(Fig. 9)
Adjustment of eccentric 22171
With eccentric 22171 you can easily increase or
reduce the distance between the mark (double
arrow) at the backing paper and the position of first
exposure. Loosen the screw 820013 and rotate the
eccentric to the required position and then tighten
the screw. Note! The screw shall be secured with
loctite. In fig. 9 you can see the basic position of the
eccentric, which is set to fit our reference film (Kodak
Plus-X).
Fit the cover, secure with 3 screws 823012 and put
the leather back.
Fit the magazine slide holder when necessary.
Spool holder(see page 15 and 16)
Reassembly 2:4
CAUTION! When handling the circuit board a
grounded bench mat and a wrist strap must be used
to prevent ESD damage.
Fit the support and end plate with 4 screws 823650
(secured with loctite). Thread the 4 cables 308043
through the end plate and solder them on the circuit
board. Press the circuit board on to the end plate, and
if necessary, replace the tape 308495. Fit the dials,
indicators, cover, leather and rubber plate. Fit the felt
ring 308410, thread the washer 810925 over the lock
308101 and fit it as well as the film signal 22382 into
the spool holder, together with gear 22375 so that
you will get a red indication in the film indicator
(exact adjustment will be set later), fasten the locking
handle with clip 817140. Fit the 2 rollers 13514,
locking shaft 308103 and spring 12540.

Fit the plate 312105 and take-up arm 22398,
connect spring 814952. Place the film indicator gauge
V-5065 (magazine 12 and 16) or V-5068
(magazine 24) on the feeding side of the spool
holder. Adjust the indicator by holding the gear
22375 in place and thereafter turn the shaft of the
film signal 22382 to the position as shown in the
diagram (Fig. 10). Take the film indicator gauge off
and check that the film signal is changing to fully red
(Fig. 11). Secure the gear 22375 to the shaft with
safety lacquer. Fit the contact assembly 308043 in
plate 312105 with 2 screws 826028. Loosen the
screws 824033 somewhat, lift up plate 312105 and
fit the plate spring 13913 and the pressure plate
308104, then tighten the screws 824033.

Final checks
Insert the spool holder in to the magazine, advance
and check that the automatic stop is functioning
(first exposure). Adapt the magazine on a camera
body and make some test exposures.
Check that the film counter, exposure signal, etc.
are functioning. Take the spool holder out and check
that the film counter sets to zero.
Load the magazine with film and check the spacing
i.e. that you after every exposure are making a mark
on the film inside the picture frame and then check
the placing of the "exposures". Check also that the
film indicator gradually changes from white to red as
the film is wound through.
Reassembly 2:5
After the repair of E or TCC magazine the speed
and film contrast dials shall be checked. Adapt the
magazine on a 203FE or a 205FCC camera and
connect it to the Hasselblad Service Test System.
Choose the function "203/205" from the main
menu, then choose the function "MAGAZINE"
from the sub menu. Turn the ISO dial and the film
contrast dial from 12 to 6400 and from -4 to +3
respectively and back again.
