Except for the both sides covers,
each cover
can be taken apart
from
the camera
body independently
of the other
cover.

Insure
that the shutter is released when
removing
the retainer
screw
(C126) of the exposure counter dial.
Otherwise,
the-lip of the spool

control dial (C105),
etc. must be re-
moved,
and Main gear (C01) must be returnedto its original position,
before taking Top cover right (A07) apart from
the body.
It is recommended
to fix the dial again after taking

for
facilitating the handling

Before taking off Top cover left (A08),
Shutter dial (D125) must be
removed.

MIRROR HOUSING
Decoupling
of the body and mirror
housing
can be done by pushing
up
the mirror
housing from
the body.
Following
parts,
however,
must
be
taken apart beforehand.

Screws
and others.
Points for the decoupling are:-
* Push up
the mirror housing after releasing the shutter if it is cock-
ed, as the Re-set actuator (E87) in cocked position disturbs the ope-
ration.
* The connecting
gear (C08)
should be pulled out until it stops contact-
ing the pinion shaft,
then turn it around
the shaft to take it out.
+ Beware
of the curtain edgers and tapes which may
get caught to the
body.
OTHERS
Curtain bounce prevention system
Avoid
unnecessary
disengagement
of the damper
gears and pinion
gears,
as their engagement
requires a delicate adjustment.
If they are disengaged,
do not try to operate the shutter.
It will
cause
a curtain tape peeling off.
