OIL
FILTER.
(FULL
FLOW.)
a.
The
oil
filter
element
should
be
replaced
after
each
50
hours
of
engine
operation;
this
is
accomplished
by
removing
the
lockwire
from
the
bolt-head
at the
end
of
the
filter
housing,
loosening
the
bolt,
and
removing
the
filter
assembly
from
the
adapter.
b.
Before
discarding
the
filter
element,
remove
the
outer
perforated
paper
cover,
using
a
sharp
knife,
cut
through
the
folds
of
the
element
at
both
ends,
close
to
the
metal
caps.
Then,
carefully
unfold
the
pleated
element
and
examine
the
meterial
trapped
in
the
filter
for
evidence
of
internal
engine
damage
such
as
chips
or
particles
from
bearings.
In
new
or
newly
overhauled
engines,
some
small
particle
of
metallic
shavings
might
be
found;
these
are
generally
of
no
consequence
and
should
not
be
confused
with
particles
produced
by
impacting,
abrasion
or
pressure.
Evidence
of
internal
engine
damage
found
in
the
oil
filter
justifies
further
examination
to
determine
the
cause.
c.
After
the
element
has
been
replaced,
tighten
the
attaching
bolt
within
20
to
25
foot
pounds
of
torque.
Lockwire
the
bolt
through
the
loops
on
the
side
of
the
housing
to
the
drilled
head
of
the
thermostatic
valve.
Be
sure
the
lockwire
is
replaced
at
both
the
attaching
bolt
head
and
the
thermostatic
oil
cooler
bypass
valve.

RECOMMENDATIONS
FOR
CHANGING
OIL.:(Refer
to
latest
revision
of
Lycoming
Service
Instruction
No.
1014.)
a.
In
engines
that
have
been
operating
on
straight
mineral
oil
for
several
hundred
hours.
a
change
to
additive
oil
should
be
made
with
a
degree
of
caution,
since
the
cleaning
action
of
some
additive
oils
will
tend
to
loosen
sludge
deposits
and
cause
plugged
oil
passages.
When
an
engine
has
been
operating
on
straight
mineral
oil
and
is
known
to
be
in
excessively
dirty
condition.
the
switch
to
additive
or
compounded
oil
should
be
deferred
until
after
the
engine
is overhauled.
b.
When
changing
from
straight
mineral
oil
to
compounded
oil,
the
following
precautionary
steps
should
be
taken:
1.
Do
not
add
additive
oil
to
straight
mineral
oil.
Drain
the
straight
mineral
oil
from
the
engine
and
fill
with
additive
oil.
2.
Do
not
operate
the
engine
longer
than
five
hours
before
the
first
oil
change.
3.
Check
all
oil
screens
for
evidence
of
sludge
or
plugging
and
change
oil
every
ten
hours
if
sludge
conditions
are
evident.
Resume
normal
oil
drain
periods
after
sludge
conditions
improve.

LUBRICATION
INSTRUCTIONS.
Proper
lubrication
procedures
are
of
immeasurable
value
both
as
a
means
of
prolonging
the
service
life
of
the
airplane
and
as
a
means
of
reducing
the
frequency
of
extensive
and
expensive
repairs.
The
periodic
application
of
recommended
lubricants
to
their
relevant
bearing
surfaces,
as
detailed
in
the
following
paragraphs,
together
with
the
observance
of
cleanliness,
will
insure
the
maximum
efficiency
and
utmost
service
of
all
moving
parts.
Lubrication
instruction
regarding
the
locations,
time
intervals,
and
type
of
lubricants
used
may
be
found
in
the
Lubrication
Chart.
To
insure
the
best
possible
results
from
the
application
of
lubricants,
the
