Note: Care must be taken so that the flex (22915)
will not become damaged during the separation.
To accomplish this separation requires manipulation
of the shell and body in order that the gearing, on the
right hand wall of the camera shell, does not snag on
the camera shell. When the shell and body have been
separated the teflon button (103773) can also be
removed if required.

to the main camera body. Remove the two screws
(823015) that secure the bayonet plate to right hand
wall of the camera body (i.e. the side upon which the
mode selector is mounted).
When separating the bayonet plate from the rest of
the camera body a firm grip should be maintained on
the gear (13556), thus ensuring that tension on the
spring behind it is not quickly relieved.
When the bayonet plate has been separated from the
rest of the camera body the gear should be gradually
released allowing the tension on the spring to be
gradually relieved. Remove gear (13556) and disc
(21324)) with screw (821033) from bayonet plate.

Before fitting the bayonet plate (30706-1) make sure
the camera is released. This is done by turning gear
(22476). Note that the pin "A" should be visible from
the outside.

Fitting the front bayonet plate to the camera body:
Tension the drive spring by turning the front gear
wheel (30413) clockwise 3 turns.
Fit in the lower part of the bayonet plate so that the
check "C" on the front gear cam plate is stopped by
the spring (22317). Ensure that the two indexes "A"

The key position of the front gear is checked with the
camera cocked. This is carried out as follows:
Fit the blade of a screwdriver in the slot on the front
gear wheel (30413). Turn the gear in a clockwise
direction until the check "C" has passed the locking
arm (21219). In this position it is now possible to
cock the release arm (22922) against the release catch
(13570). Continue the cocking action until the
locking arm (21219) operates and is blocked against
the check "D".

Mount the key inspection tool 902658 (V-2075) to
the camera's front bayonet plate. Ensure the indicator
is pointing upwards when the camera is cocked.

With the tool 902658 (V-2075) fitted to the front of
the camera, the key position should have a minimum

Mount the front plate "A" in the front of the camera
body and place the camera with the rear section in
control tool V-2229.
Check that the rear section is flat.
If the rear section is warped, the first procedure is to
ensure that both the inner walls of the camera are in
good contact with the inside of the rear section. This
is carried out by knocking carefully on the front plate
with a plastic-faced hammer.
If this operation is insufficient, it is possible to adjust
the warp at the corners which may be too low.
Loosen the two nearest screws and push the rear
section backwards until it is flat. Then tighten the
screws.
Place the camera body in control tool V-2229
without tensioning it. Set the ruler with the indicator
clock to zero by placing it on surface "B".

Place the ruler with indicator clock onto the gauge
and move the indicator around the periphery on the
front plate and check that the length is within the
tolerance.
If the camera body is too short, on the left-hand side,
then the front must be moved forward on this side.
This is carried out by knocking on the angle on the
left wall which provides the support for the bayonet
plate. A solid fibre rod and a suitable hammer are
used for this operation.
Re-check as described above.
If the camera is too short on the right hand side, it
must extended. This is carried out by moving the rear
section to the rear. Loosen the screw (820025) on the
right wall (30748), the screw (820015) on the bottom
of the camera and the screw (820017) on top of the
camera. Insert the blade of the screwdriver first in one
and then in the other of the two rectangular recesses
in the rear edge of the right wall close to the rear
section and turn carefully. Then tighten the screws
and check on control tool V-2229 that the rear
section has not become distorted during adjustment.
Fig. 36.
Reassembly
Check the length measurement above.
If the total length measurement of the camera body is
too long, adjust the bayonet front plate downwards
by knocking on the front plate "A" at the points
where necessary.
Re-tighten all screws retaining the rear section, the
front plate and the frame.
Note! The focal length is checked once more when
the camera is fully reassembled.

Dog (13525), gear (13567) and gear
(13556)
Cock the camera as follows:
Fit the blade of a screwdriver in the curved slot on
the front gear (30413). Turn the gear in a clockwise
direction until the check "C" has passed the locking
arm (21219). In this position it is now possible to
cock the release arm (22922) against the release catch
(13570). Continue the cocking action until the
locking arm (21219) operates and stops against the
check "D".
Fig. 37.
Lubricate the front gear journal "F". Locate the dog
(13525) onto the pin "E" with the bent lug upwards.
Place the disk (21324) with the large flange
downwards on the front gear journal. The recess in
the disk fits against the pin on the front gear cam
disk.
Check that both catches on the gear (13556) move
easily and that the spring-loaded setting hook returns
under the influence of its own spring. If the
movement of the catches should be doubtful, this can
possibly be adjusted by carefully bending the ring
which is riveted on.

The gear (13556) is fitted so that the point of the
hook which is not spring-loaded comes into contact
with the recess in the disk (21324). Turn the gear in a
clockwise direction until the spring-loaded setting
hook stops against the check "G" as shown in Fig. 37.
The dog (13525) is backed off in an anti-clockwise
direction so that the bent lug rests against the
periphery of the spring-loaded setting hook in gear
(13556).
Fit gear (13567) with the pin pointing downwards
from "E".
Fig. 37.
Note that the gear (13556) and the dog (13525) must
be retained in the positions previously described. This
facilitates adjustment. Ensure that the pin on gear
(13567) is placed in the hole on the dog (13525) in a

When the gear (13556) is turned in a clockwise
direction the dog (13525) should release the setting
hook from the check "G".
Fig. 39.
Adjustment: Disengagement should occur when the
check "D" has passed the locking arm (21219) and
moved a further 1 - 2 mm. (this is a safety margin to
ensure that the lens is fully cocked).
Fig. 39.
If a further movement is needed, then the
relationship between the dog (13525) and the gear
(13567) must be altered.
Adjustment: If smaller movement is required, lift the
gear (13567) out of engagement with gear (13556).
Turn gear (13567) one (1) tooth segment in an anticlockwise direction. Re-check as specified above.

Note that the front gear (30413) must be held when
the screw for gear (13556) is tightened. This can be
done in a convenient way by inserting the blade of a
screwdriver on the underside of the camera between
the spring stop (22317) and the fixed gear on the
front gear.
Gear (13557)
The initial position for fitting gear (13557) is as
follows. The dog (13525) has just operated the springloaded setting hook on gear (13556) and further
movement has been checked as described previously.
Gear (13556) is backed in an anti-clockwise direction
until the spring-loaded setting hook stops against the
upper point "G" on the front cam disk.
