LYCOMING AT OVERHAUL PARTS REPLACEMENT LIST - O-320-A2D AND E SERIES Lycoming engines are the culmination of hundreds of parts improvements made over the last six decades. TECHNICAL PUBLICATION REVISION REVISION No. PC203-2-A ENGINE MODEL PUBLICATION No. 0-320-B and -D Series. When used in conjunction with the appropriate overhaul manual, shall be used for parts identifica. Lycoming accepts responsibility for quality control and/or airworthiness of parts which do not pass through the.
The Lycoming O-320 is a large family of 92 different naturally aspirated, air-cooled, four-cylinder, direct-drive engines commonly used on light aircraft such as the Cessna 172 and Piper Cherokee. Different variants are rated for 150 or 160 horsepower (112 or 119 kilowatts). As implied by the engine's name, its cylinders are arranged in horizontally opposed configuration and a displacement of 320 cubic inches (5.24 L).[1]
Design and development[edit]
The O-320 family of engines includes the carbureted O-320, the fuel-injected IO-320, the inverted mount, fuel-injected AIO-320 and the aerobatic, fuel-injected AEIO-320 series. The LIO-320 is a 'left-handed' version with the crankshaft rotating in the opposite direction for use on twin-engined aircraft to eliminate the critical engine.[2][3]
The first O-320 (with no suffix) was FAAcertified on 28 July 1953 to CAR 13 effective 5 March 1952; this same engine was later re-designated, without change, as the O-320-A1A.[2] The first IO-320 was certified on 10 April 1961, with the AIO-320 following on 23 June 1969 and the first aerobatic AEIO-320 on 12 April 1974. The LIO-320s were both certified on 28 August 1969.[2][3]
The O-320 family of engines externally resembles the Lycoming O-235 and O-290 family from which they were derived. The O-320 shares the same 3.875 in (98 mm) stroke as the smaller engines, but produces more power with the bore increased to 5.125 in (130 mm). The design uses hydraulic tappets and incorporates the provisions for a hydraulically controlled propeller installation as well. The controllable-pitch propeller models use a different crankshaft from those intended for fixed-pitch propellers.[4]
The O-320 uses a conventional wet sump system for lubrication. The main bearings, connecting rods, camshaft bearings, tappets and pushrods are all pressure lubricated, while the piston pins, cylinder walls and gears are all lubricated by spray. The oil system is pressurized by an accessory-drive mounted oil pump. A remotely mounted oil cooler is used, connected to the engine by flexible hoses.[4]
The 150 hp (112 kW) versions of the carbureted O-320, are approved for the use of 87 AKI automotive gasoline. Only one model of the 160 hp (119 kW) variants of the 0-320 is not approved, and that is the H2AD model. All other 160 hp (119 kW) 0-320s are approved for 91 AKI. Airframe approval is also necessary to use automotive gasoline in any certified aircraft.[5]
The factory retail price of the O-320 varies by model. In 2010 the retail price of an O-320-B1A purchased outright was USD$47,076[6]

The Lycoming O-290 is a dual ignition, four-cylinder, air-cooled, horizontally opposedaircraft engine. It was first run in 1939, and entered production three years later.
A common variant of the type is the O-290-G, a single ignition model which was designed to drive a generator as part of a ground power unit.
