Model of Engine
The TSl0-520-BE engines are air cooled, having six horizontally opposed, overhead, inclined valve cylinders.
The cylinder displacement of 520 cubic inches is achieved with an 5.25 inch bore and a 4.00 inch stroke.
The TSI0-520-BE engine is turbosupercharged and has a 7.5 to 1 compression ratio. The TSI0-520-BE
engine is fuel injected with a pressurized, balanced induction system. The crankshaft is equipped with
pendulum type counterweight dampers that suppress torsional vibrations.
The TSl0-520-BE engine has a doweled six bolt hole configuration propeller flange. A mounting pad is
provided to utilize a hydraulic controlled governor for the constant speed propeller.
The TSI0-520-BE engine is a wet sump design with a positive displacement oil pump installed on the lower
aft portion of the crankcase. The desired oil pressure is maintained by a pressure relief valve located in the
oil pump housing. Engine oil temperature is maintained by an oil temperature control valve located in the
oil cooler. Engine cranking is accomplished by a geared right angle drive starter adapter and a direct current
starter motor.
A gear driven alternator is installed on the right front side of the crankcase forward of the number 5 cylinder.
The engine is equipped with two gear driven magnetos. The exhaust system is supplied by Teledyne
Continental Motors.
3-3 LUBRICATION SYSTEM
Oil is drawn from the sump through the suction tube to the intake side of the engine driven, gear type, oil
pump. From the outlet side of the pump, oil is directed to the full flow, replaceable oil filter. A bypass valve
is incorporated in the filter in the event that the element becomes clogged. An oil pressure relief valve is
incorporated in the oil pump housing.
From the filter discharge port, oil is directed through a crankcase passage to the oil cooler. In addition to
facilities for temperature and oil pressure connections, the oil cooler incorporates an oil temperature control
valve. Oil passing through the oil temperature control valve cavity is directed either through the oil cooler
or directly to the crankcase passage to the rear of the camshaft, depending on the oil temperature. In this
manner, engine oil temperature is maintained at 180°F.
Oil entering the engine is directed to the hollow camshaft, which serves as the engine main oil gallery.
Grooves and drilled holes in the camshaft are located so as to afford proper lubrication through a system
of orifices to the main bearings, lifters, idler gear bushing, accessory drive gear bushings and the starter
drive gear bearing.
