b. SHUTTER CURTAIN PARTS
NOTE: When attempting to overhaul the shutter curtain parts, strict care must be exercised not to tear off
the curtain from the pipes; not to make a hole in the curtain with such tool as tweezers; and not to
stain them with oil.
(1) Curtain Spring Adjust Gear A (E92)
Put a driver into the slot of the curtain spring adjust gear A (E92i to prevent its rotation, take out the
curtain spring adjust lug (E42) from the gear, and then turn the driver slowly clockwise, thereby placing
the curtain spring back to its original position with no tension. For overhauling (E93), the same
procedure may be followed.
NOTE: The curtain spring should never be placed back to its original position rapidly. Put a driver into
the upper slot of the 1st curtain shaft (E33) to prevent its movement, and turn (E92) clockwise,
unloosening the screw to take it out. The curtain spring adjust gear B (E93) should also be
overhauled in exactly the same manner. Remember that (E92) and (E93) screw counter-clockwise.
(2) Sync. Gear (E104)
If LW13 is pulled out of the sync, gear column (E105), (E104) can be removed.
(3) Top Shaft Plate (E01)
When 2 pcs of LW13 and 2 pcs of screw (72) are removed, the curtain pipes and shutter curtains can be
taken out in a body from the body proper.
(4) Top Mec Plate (C01)
Ease the 1st curtain checker arm stopper (E86) and stopper column (C42), and the 1st curtain pinion
shaft (E31) and 2nd curtain pinion shaft (E32) can be taken out in a body from the body proper.
(5) Top Mec. Plate (C01) and Shutter Curtains
Ease 3 pcs of pinion shaft retainer screw (E55) and the 1st, and 2nd curtain pinion shafts (E31) (E32) can be
pulled out of (C01).
6. Disassembly of Mirror Housing Mechanism.
NOTE: Overhauling of the mirror housing mechanism may be made from any parts you desire, but the
following points must be borne in mind:
(a) Do not turn the red lacquer sealed 2nd dia. lever adjust screw (B59), because this screw is
adjusted to cause the rotation of the 2nd dia. lever (B54) when the shutter bottom is depressed to 1.2
- 1.7 mm.
(b) Do not ease the mirror seat rest screw (B13) which retains the mirror seat rest (B14). The
(B14) is properly adjusted to maintain the mirror at the correct 45° angle whenever it is down.
(c) Remember well the exact location of the washers located in between the mirror actuator
lever, top (B18), mirror actuator, bottom (B19) and mirror actuator lever shaft (B35), as the
washers are adjusted to prevent clearance of these parts.
