MANUAL
IMPORTANTSAFETY NOTICE
Proper service and repair is essential to increase the safe, reliable
operation of all aircraft engines. The service procedures recommended
by Textron Lycoming are effective methods for performing service
operations. Some of these service operations require the use of tools
specially designed for the task. These special tools must be used when
and as recommended.
It is important to note that most Textron Lycoming publications con-
tain various Warnings and Cautions which must be carefully read in
order to minimize the risk of personal injury or the use of improper ser-
vice methods that may damage the engine or render it unsafe.
It is also important to understand that these Warnings and Cautions
are not all inclusive. Textron Lycoming could not possibly know,
evaluate oradvise the service trade of all conceivable ways in which ser-
vice might be done or of the possible hazardous consequences that may
beinvolved. Acordingly, anyone who uses a service procedure must first
satisfy themselves thoroughly that neither their safety nor aircraft safe-
ty willbe jeopardized by the service procedure they select.

SECTION1
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.

Valve Operating Mechanism -A conventional type camshaft is located
above and parallel to the crankshaft. The camshaft actuates hydraulic
tappets which operate the valvesthrough push rods and valverockers. The
valverockers are supported on full floating steel shafts. The valvesprings
bear against hardened steel seats and are retained on the valvestems by
meansof split keys.
Crankcase- The crankcase assembly consistsof two reinforced aluminum
alloy castings, fastened together by means of studs, bolts and nuts. The
mating surfaces of the two castings are joined without the useof a gasket,
and the main bearing bores are machined for useof precision type main
bearinginserts.
Crankshaft - The crankshaft is made from a chrome nickel molybdenum
steel forging.Allbearingjournal surfacesare nitrided.
Connecting Rods -The connecting rods are made in the form of "H"
sectionsfrom alloy steel forgings.They havereplaceablebearinginserts in
the crankshaft ends and bronze bushings in the piston ends. The bearing
caps on the crankshaft ends are retained by two bolts and nuts through
eachcap.
Pistons - The pistons are machined from an aluminum alloy. The piston
pin is of a full floating type with a plug located in each end of the pin.
Depending on the cylinder assembly, pistons may be machined for either
three or four rings and may employ either half wedgeor full wedgerings.
Consult the latest revision of Service Instruction No. 1037 for proper
piston and ring combinations.
Accessory Housing -The accessory housing is made from an aluminum
casting and is fastened to the rearof the crankcaseand the top rear of the
sump. It formsa housing for the oil pump and the variousaccessorydrives.
Oil Sump (Except -AIO Series) -The sump incorporates an oil drain plug,
oil suction screen, mounting pad for carburetor or fuelinjector, the intake
riser and intake pipe connections.
Crankcase Covers (-A10 Series) - Crankcase covers are employed on the
top and bottom of the engine. These covers incorporate oil suction
screens, oil scavenge line connections. The top cover incorporates a
connection for a breather line and the lower covera connection for an oil
suction line.
