In this Chapter II, photographs are shown, besides diagrams, in the order of assembling, where considered
helpful. For instance, photo No. 3 shown under 1. b, illustrates the assembled condition up to the stage of the
stopper (C11).
NOTE : Disassembled parts, before assembling, need a careful washing and or dusting with either a piece of
cloth or a blower. When servicing customers' cameras, discretion, of course, has to be exercised in
this respect, taking into consideration such factors as the model, period of use, nature of defects, etc.
However, the general rules are summarized below:
Parts equipped with rotating shafts and or shaft bearings have to be thoroughly washed with quality
gasoline or benzene. Especially such parts as are to be lubricated with "L" lubricants need a careful
washing and drying. However, pipes and governor parts containing curtains or springs should never
be immersed in cleaning liquid for washing purposes.
Exposed plated and anodised parts should be thoroughly wiped either with a brush or with a clean
piece of cloth. When stains are found, lightly wipe off the stained parts with a clean piece of cloth
soaked with liquid composed of ether and alcohol at the ratio of
60% and 40%.
Painted parts need only be lightly dusted with a brush. Stains on the outer surface of black cameras
should be wiped either with silicon-cloth (similar to the one usually used for wiping glasses and is
easily available on the market! or with the aforementioned liquid composed of 60% ether and 40%
alcohol, very lightly so as not to erase the white letters engraved on the cameras.
For wiping optical parts, mixed liquid comprising 70% ether and 30% alcohol should be used. In this
connection, a clean piece of cotton or hemp cloth, properly washed beforehand and entirely devoid
of starch, or a piece of soil paper is recommended for use.
For wiping parts made of plastics (such as Fresnel and ground glass), use mixed liquid composed of
50% ether and 50% alcohol, which gives satisfactory results.
The mirror should never be wiped with a
piece of cloth under any circumstances. If wiped with such
material, it results in flaws. Dusts or dirts on the mirror need to be blown with a blower.
It is of utmost importance to abide by the instructions governing the right kind of lubricants,
lubricating positions and lubricant quantity. Lubrication needs to be performed strictly in accordance
with Attachment 2—List of Lube Oil —as wrong use of oil will invariably result in the deterioration
in performance or functioning of various parts and may cause defects.
1. Assembly and Adjustment of Shutter and Transport Mechanism.
a. SHUTTER CURTAIN PARTS
(1) After the shutter curtain parts are assembled, slowly rotate 2 or 3 times the 1st curtain shaft (E33)
and 2nd curtain shaft (E94) clockwise to tension the curtain springs. (Diagram 6) Final adjustment of the
curtain spring tension should be made at the time of adjusting the curtain travel speed mentioned
elsewhere.
