ENGINE GROUP
49. Description and Function
The engine group is a one-cylinder, four-stroke
cycle, overhead valve, aircooled, gasoline fueled unit
designed to develop hp at 3,600 rpm. Included with
the gasoline engine are various accessory components
required to facilitate operation of the unit. The splined,
engine adapter is secured to the drive shaft of the
gasoline engine and is used to drive the crankshaft of the
compressor assembly. The tube assembly is secured to
the frame assembly by a clamp and is attached to the
shutoff cock and the filter and connector. The tube
assembly is used to conduct the fuel from the fuel tank to
the carburetor of the gasoline engine. Attached to the
gasoline engine are four clip angles which are used to
mount the gasoline engine to the frame assembly. At the
rear of the gasoline engine is attached the pulley. The
pulley is used with the rope starter to manually start the
gasoline engine.
