Continental Air-cooled, 7 Cylinder, Static-radial Engine

LVT Contintental engine at Camp Pendleton LVT Museum

From sign at the WWII Korean LVT Museum:

"The engine is a W670-9A air-cooled, 7-cylinder, static-radial engine. Two magnetos, an electric cranking motor, pulley, governor, and bilge pump drive assembly, off pumps, and fuel pumps are mounted on the accessory case.

"The generator, which is mounted on a moveable bracket attached to the engine support beam, is located below and to the left of the accessory case. The carburetor is centrally mounted on the lower side of the rear crank case section. A dual-purpose gear-type oil pump supplies oil under pressure to the various engine parts, and incorporates a scavenger pump which draws oil from the engine sump and returns it to the supply tank (reservoir).

"A second scavenger pump transfers oil from the two lower rocker boxes to the main engine sump. The flywheel end of the engine is referred to as the front of the engine, the accessory end as the rear. The terms right and left are used with reference to the engine as viewed from the rear. Horizontal and vertical positions of the engine are referred to with respect to the crankshaft. When the crankshaft is in the horizontal position, the engine is in the vertical position. Direction of rotation is determined by viewing the engine from the rear."1

Continental engines were used in the LVT(2) Water Buffalo, LVT (A)1, and LVT(4).
