POWER PLANT
(PA-32RT-300T)
8A-1. DESCRIPTION.
The PA-32RT-300T
is powered
by a Lycoming
engine model TIO-
540-SIAD.
This engine
is a direct
drive, six cylinder,
fuel
injected, horizontally
opposed,
air
cooled engine with
top side exhaust
incorporating oil
jets for internal piston
cooling. The
engine
is furnished with a
starter, 60 ampers,
12-volt alternator,
voltage regulator,
shielded
ignition system,
vacuum pump drive,
fuel injector and
a dry paper type induction
filter. In the
event
of air stoppage
through the filter
an alternate air source
can be opened when
selected
manually
by the use
of a lever in
the cockpit. An
automatic
alternate air
door is also
provided
on the induction
tube downstream
from the blower.
The turbocharged
engine develops
300 horsepower
at 2700 rpm and
36 inches of mercury
manifold
pressure at take-off
for a maximum
5 minute limit. Maximum
continuous
power
rating is 270 horsepower
at 2575 rpm
and 33 inches of
mercury manifold pressure
to an altitude
of
approximately 15,000
feet. The turbocharger-blower
has an
integral overboost
safety valve.
Output is
controlled by an interconnected
control
between the injector
throttle arm and
the
wastegate
control
arm. This
mechanically
programmed
interconnect
eliminates
a separate
wastegate control lever.
The engine
is provided with
a constant speed
propeller controlled
by a governor
mounted
on
the engine supplying
oil through
the propeller
shaft at various
pressures.
8A-la. STANDARD
PRACTICES -
ENGINE.
The following suggestions should
be applied wherever they are needed
when working on
the power
plant.
a. To insure
proper reinstallation
and/or assembly,
tag and mark
all parts, clips, and
brackets
as to their
location prior
to their removal
and/or disassembly.
b.
During removal
of various tubes
or engine parts, inspect
them for indications
of
scoring, burning or
other undesirable conditions. To facilitate
reinstallation, observe the
location
of each part during
removal. Tag
any unserviceable
part and/or
units for
investigation
and
possible repair.
c.
Extreme care must
be taken to prevent
foreign matter
from entering the
engine, such
as lockwire,
washers, nuts, dirt,
dust, etc. This precaution
applies whenever
work is done
on
the engine, either on
or off the aircraft.
Suitable protective
caps, plugs, and covers
must be used
to protect
all openings
as
they are
exposed.
NOTE
Dust
caps used to protect open
lines must always be installed
OVER the tube
ends and NOT IN the tube
ends. Flow through
the lines may be blocked off if lines are inadvertently installed
with
dust caps
in
the tube
ends.
