INST.
(PlN

lnstall
the
probe
assemblies
in the tapped
holes located on the
underside
of
the
cylinders.
The
threads
in the holes
may
require
cleaning.
Proceed
carefully
to
prevent
damaging the threads.
Route
wires away
from
exhaust
stacks
and
other
heat sources
with
enough slack
to allow for
engine
vibration,
etc.
Do
not
route
the
leads
creating
stress
where
they
exit
the
probe.
A
gradual
radius away
from
the
spring is
best.
1.5.2 EXHAUST
GAS
TEMP
PROBE
INST.
(P/N
1020060)
Drill
an adequate
access hole,
for the
probe
tip,
in the exhaust
pipe,
at
a location
3.5
to 4
inches
(if
possible)
down from
the
exhaust
pipe
flange,
such
that the
lead wires
will
exit the
probe
smoothly without
creating sharp bends,
while
remaining
away from exhaust
stacks and
other heat sources.
Angle
the
probe
assembly inward
and toward
the
back
of the
engine allowing
the
leads to
be
secured as they travel
back along
the side of
the engine
oil
sump.
lnstall
the
probe
by opening
the clamp ring
and
placing
the
probe
into
the
exhaust
pipe
drilled hole.
Close and
tighten the clamp ring
using
a screwdriver.
Do not
over tighten
clamp
or
clamp
failure may
eventually
occur. Make sure
the
clamp
is not
crooked
on the
exhaust
pipe
or
it
will loosen up during
flight.
Secure the wires
along their
paths
to
the
DPU, to
prevent
vibration
and
abrasion with enough
slack to
allow for engine vibration, etc.
Route
wires away
from exhaust stacks
and other
high heat
sources.
Do not
route
the
leads creating
stress where
they exit
the
probe.
A
gradual
radius
away from the
spring is
best.
Use
standard aircraft
wiring
techniques
and materials.
