The entire unit, including radiator, engine, alternator, and control panel, is mounted on an electrically welded steel bedplate. A 15-gallon gasoline tank is mounted over the flywheel housing. The engine is equipped with a fuel pump for supplying gasoline to the carburetor either from this tank or from drums of gasoline that may be placed alongside the power unit. A gear-type lubricating oil pump, equipped with a renewable cardridge-type oil type, furnishes oil under pressure to all engine bearings.
