Sight disassembly and reassembly
RESTRICTED
SECTION VII
DISASSEMBLY AND REASSEMBLY SIGHT
Bombsight maintenance
personnel should always
keep in mind one
important maintenance principle.
That
is, that
long
the equipment
is func-
tioning
perfectly there
is no need
for a partial
or complete disassembly.
Any complete disassembly
should be done
by men
specifically
trained
for
that job.
In the majority of
cases,
the maintenance man
will have new equipment which
is accurately cali-
brated.
There are doubtless many
instances in
which the equipment arrives improperly calibrated.
This should be checked for and any steps of cali-
bration called for should be performed.
Calibra-
tion,
however, does not
involve disassembly. Check
should be made
to see
that the equipment is func-
tioning properly, and if it is, do only
the neces-
sary
maintenance
required
to maintain the
effi-
cient operation.
That maintenance would consist
of
the inspections out lined in the C. L. l. and
on
the first page of the log book.
In the following section on
disassembly and
assembly no attempt is made to give complete dis-
assemb!y, but rather that which is most frequently
encountered by the maintenance personnel and
the
is required in order to ciean
the parts of the sight most frequently requiring
cleaning and
lubricating for proper maintenance.
The outiine of disassembly procedure
is not
the only
means of disassembly, but is one which
been
used
and which has proved to be satis-
factory. This
procedure is to be used
as a guide
and is
not to
be memorized.
The
maintenance
man
should be so thoroughly familiar with
the equip-
ment that
correct disassembly and
assembly
procedure will be automatic. An orderly proce-
dure will prevent damage
to the equipment and
will save
precious
minutes.
Always remember that
the bombsight equipment
is precision made and that parts are never
to be
forced.
If.
at any
time,
trouble is encountered,
always
contaci your superior, and in the absence
of the
proper superior use your head and reason
out the solution.
