COOLING SYSTEM. Air for cooling is drawn into engine compartment through air intake grille
doors by two engine-mounted fans which draw air through engine and transmission oil coolers,
over cylinder fins, and discharge air vertically from engine shroud. Baffles and deflectors on
cooling fan shroud direct air flow across cylinders.
TRANSMISSION SHROUD.
Insulated sheet metal assembly fitting over top and rear
portions of transmission.
ENGINE SHROUD.
Sheet metal assembly covering top of engine, guides hot air from
engine cooling fans toward rear of tank. Removed with powerplant.
COOLING FANS. Mounted on oil-driven centrifugal clutch and disk towers on engine, fans
draw air through engine and transmission oil cooler cores to cool circulated oil. Fans draw
air over baffles and deflectors on engine and shroud to direct air flow across cylinders.
Fans also force hot air and exhaust gases through exhaust doors.
