Cleaning
the
Model
25
Movement
After
removal
of
the
balance
wheel,
and
the
other
ports
mentioned
on
Pages
25.3
through
25.5,
the
movement
is
ready
to
be
cleaned.
If
a
cleaning
machine
is used,
place
the
movement
in
the
basket
with
the
dial
plate
down
to
insure
proper
drainage
of
the
fluid
from
the
mainspring
barrel.
It
should
be
well swirled
in
the
cleaning
fluid
after
which two
sets
of rinsing
fluid
should
be
used.
The
final
cleaning
fluid
must
be
absolutely
clean.
After
cleaning,
the
movement
should
be
thoroughly
dried.
If
a
cleaning
machine
is
not
available,
the
some
procedure
should
be
followed
manually,
by
re-inserting
the
stem
into
the
movement,
grasping
the
movement
firmly
around
the
stem
and
shaking
it
in
the
cleaning
and
rinsing
fluids
to
insure
that
the
fluid will
pass
through
the
entire
mechanism.
The
balance
assembly
should
be
cleaned
separately
in a
small
jar
to
prevent
damage
to
the
hairspring.
Only
standard
watch
cleaning
solutions
should
be
used
throughout.
Lubricating
the
Model
25
Movement
The
movement
should
be
re-oiled
in
the
normal
manner
using
only
high
grade
watch
oils (oil
used
in
factory
assembly
is
Elgin
M56b).
The
mainspring
is
permanently
lubricated
with a
solid
coating
which
is
not
affected
by
normal
cleaning
solutions
and
should,
therefore,
not
be
oiled.
The
upper
pivot
of
the
escape
wheel
con
be
oiled
through
the
holes in
the
-minute
wheel.
The
"V-conic"
bearings
should
be
oiled
V2
to
%
full
before
replacing
the
balance
wheel.
Oil
both
the
top
and
bottom
sides
of
the
intermediate
wind pinion
and
wind
and
set
pinions.
Oi
I
the
intersection
of
the
rocking
bar
and
set
lever.
A
slot
has
been
provided
at
the
bose
of
the
center
post
to
facilitate
oiling
the
fourth
pinion
upper
pivot.
If
the
friction
pinion
has
been
removed
from
the
cannon
pinion
and
cleaned,
oil
the
friction pinion
before
re-assembly
into
the
cannon
pinion
.
The
impulse
pin
should
be
oiled
at
its
working
surface.
Rubber
gaskets
used
on crowns,
such
as
the
type
used
on
waterproof
and
dust-
proof
models,
should
be
lubricated
with
silicone
grease
or
silicone oil.
