	Lycoming - Wikipedia, the free encyclopedia
		Lycoming is a major aircraft engine company, known primarily for their smaller general aviation engines.
		Lycoming first set up business in 1916 in Williamsport, Pa (in Lycoming County) as a sewing machine manufacturer, and soon branched out into bicycle manufacturing as well.
		The hyper engine concept was a psychological target for engine designers in the 1930s; in order to make really long-distance flights routine, an engine of this sort of power-to-weight ratio would be needed to lift the required fuel and still have power left over to lift the cargo.

	Textron Businesses: Bell: Lycoming: Lycoming Selected Products
		Lycoming has six families of engines: the 235, 320, 360, 540, 580 and 720 cubic inch series.
		In addition, the engine is reassembled with all new cylinder assemblies, including barrels, heads, pistons, rings, piston pins and plugs, intake and exhaust valves, springs, guides, seats and gaskets plus automatic replacement of any and all parts not meeting new engine tolerances throughout the engine.
		And a Lycoming factory overhauled engine is backed by a factory warranty for a full year from the time it is put back in service, regardless of the number of hours flown before overhaul.

	Lycoming O-320 in the Swift
		When the engine started, whatever oil pressure was in oil line would compress the air some, but there was no way to force the air from the top of the radiator.
		The engine is the early O-320A (2B) The cowl is replaced with a fiberglass cowl, as a matter of fact, the whole firewall forward is replaced.
		The engine from a Twin Commanche is not the one STCed for the Swift.

	Light Speed Engineering - Products - Direct Crank Sensor
		On engines that should have their magnetos timed at 25 degrees the leading magnet should be installed at 45 deg BTDC and thereby 45 degrees to the right of the TDC magnet.
		Lycoming external engine dimensions can vary significantly, so you need to verify the proper clearance between the sensor and the magnets installed in the flywheel surface.
		If you are removing a magneto that has a pilot bearing on the engine side of the magneto, be sure to remove the entire bearing with the magneto.

	Continental or Lycoming aircraft engine is hard to start
		If the engine has a tendency to start when you let go of the starter switch or if the engine starts better with a low battery; then the engine is firing too early in the stroke.
		Engines that fire all the bottom plugs on the left magneto can be hard to start especially in cold weather due to the possibility of plug fouling.
		After an engine is shutdown, the temperature of its various components begins to stabilize; the hotter parts such as cylinders and oil cool, while other parts heat up due to the lack of air flow, heat conduction, and heat radiation from those parts of the engine which are cooling.

		Supercharged Lycoming V-8 automobile engine Designated the FC engine it was the sucessor the the FB (which was always designed with supercharging in mind).
		This engine is a radical departure from earlier Lycoming opposed designs in that it uses barrel tappets, the pushrods are on the bottom, it uses a spur reduction gear, and it mounts the starter and generator at the front via a gear drive.
		Lycoming XR-7755 This behemoth is the largest piston aircraft engine ever built in the free world.

		Lycoming engines powered 57 different makes of automobiles in 1924 alone, and then became a subsidiary of the Cord and Auburn automobile firms.
		Harold Morehouse was involved in the design of this series and continued active participation in the design and development of Lycoming engines until his retirement at the end of 1965.
		The engine was announced on July 23, 2002 at the Experimental Aircraft Association AirVenture 2002 in Oshkosh, Wisconsin.

		Lycoming oldtimers report that when they delivered the other engine to the program office at Wright-Patterson AFB, they were directed to "dump it on the ground." That engine is presumed to have been scrapped before making it into the AF museum's engine collection.
		She was on her way to visit my father, who had been sent from Lycoming to help the Piaggio Company set up testing facilities and procedures for the Lycoming engines they were building under license.
		One of the "perks" for Lycoming engineers was the possibility of a summer job for offspring who were in engineering school themselves.

	Plane & Pilot Magazine \| Straight Talk From Lycoming
		Lycoming also has given it direct-drive abilities and fuel-injection to make it one of the most powerful and efficient in its class.
		While the new engine announcements were the biggest news from Lycoming, perhaps more important is the restructuring and modernization now under way at Lycoming’s engine factory.
		Lycoming already has installed automated test cells so that vastly improved metrics are developed when every engine is tested.

	Low power or RPM in Continental or Lycoming aircraft engine
		If movement in either direction exceeds twenty degrees of engine rotation before motion of the rocker arm occurs, the crankshaft to camshaft timing is not correct and the engine was assembled incorrectly.
		Textron Lycoming estimates that approximately 1,252 fuel pumps were manufactured between September 18, 2000 and February 18, 2001 with a potential to fail, but they can not predict if or when the failure may occur.
		Now the engine drops two cylinders and runs rough because two hydraulic lifters on one side of the engine are pumping up and holding the valve open.

		The 1200 hp O-1230 Hyper Engine was their attempt to produce a hyper engine, an aviation engine that could produce one horsepower per cubic inch (46 kW/L) of engine displacement.
		From this point on the piston and turbine engine lines remained separate, with the piston lines being build in the original Williamsport factories, and turbines in Stratford.
		Their most successful post-war products were a series of four and six-cylinder opposed air-cooled general aviation engines.

		To my knowledge the small pin had to be installed before I bought the engine from a retired airline captain in Miami who had it in his living room as a standby for his Lake amphib, then went to a 200hp powerplant.
		My consensence from all the evidence is that someone before I got the engine was into the carb and when the cotter key was found to be almost impossible to install, went for the much smaller one.
		In this installation the engine was rebuilt and balanced and while running you could hold your hand on the mount and feel no vibration whatsoever.

	Starter Certification 101
		On factory pull-start engines (C85-12 thru O-300-C), authority is by modification per STC SE10076SC (engine modification) and STC SA10077SC (airframe modification to replace pull-start mechanism with push to start button).
		Lycoming Service Instruction 1154(current revision) is documentation allowing these starters to be installed a replacement for identical or any previously certified Lycoming starter.
		Like the Lycoming installations, the "FAA-PMA" nameplate on the starter, logbook entry by certified AandP and a WandB change in the AFM are all that are needed to certify the installation of Sky-Tec's Franklin starters (copies of the PMA are for your information only and are never required for certification).

		Their experts were able to determine that Lycoming's design for the crankshafts, which dates back to smaller, lower horsepower engines from 40 years ago, was inadequate for the larger, higher horsepower engines that failed.
		Lycoming had added Vanadium to make the steel harder and reduce the number of machining operations.
