0-360 and ASSOCIATED MODELS SECTION 1
SECTION 1
DESCRIPTION
The O, HO, 10, AIO, HIO, LIO and TIO-360 series are four cylinder,
direct drive, horizontally opposed, air cooled engines.
In referring to the location of the various engine components, the parts
are described
as installed in the airframe.
Thus, the power take-off end
is
the front and the accessory
drive end the rear. The
sump section is the
bottom
and the opposite side of
the engine where the shroud
tubes are
located the top. Reference to the left and right side is made with the
observer facing the rear of the engine. The cylinders are numbered from
front to rear, odd numbers
on the right. The direction
of rotation of the
crankshaft, viewed
from the rear, is clockwise.
Rotation for accessory
drives is determined with the observer facing the drive pad.
NOTE
The letter "L" in the model prefix denotes the reverse rotation of the
basic model. Example: model 10-360-C has clockwise rotation of the
crankshaft.
Therefore, LIO-360-C
has counter-clockwise rotation
of the
crankshaft. Likewise,
the rotation of the accessory
drives of the LIO-360-C
are opposite those of the basic
model as listed in Section 2
of this manual.
The letter
"D" used as the 4th or 5th
character in the model suffix
denotes that the particular
model employs dual magnetos
housed in a
single housing. Example: All information pertinent to the 0-360-A116
will apply to 0-360-A IF6D.
Operational
aspects of engines are the same
and performance curves and
specifications
for the
basic model
will apply.
Cylinders - The cylinders are
of conventional air cooled construction
with
the two major
parts, head and barrel, screwed
and shrunk together. The
heads are made from
an aluminum alloy casting with
a fully machined
combustion chamber.
Rocker shaft bearing supports
are cast integral with
the head
along with housings to form
the rocker boxes. The cylinder
barrels
have deep
integral cooling
fins and the
inside of the
barrels are
ground and
honed to a specified
finish.
