TM 9-2320-365-34-1c. Transfer Case. The transfer case (3, Figure 1-5) provides the transmission (2) with the seventh gear (low gear,or 1st gear) and delivers power from the transmission to the front and rear driveshafts. In normal driving conditions,the transfer case splits the output torque of the transmission, providing 70 percent of the torque to the rear output driveyoke and 30 percent to the front output drive yoke. In low gear the output torque of the transmission is split evenly,with 50 percent going to the front output yoke and 50 percent going to the rear.d. Suspension. The suspension system is designed to maintain tire/ground contact in all types of terrain. the vehicleis equipped with 395/85R20 tires. The tires have a tread pattern designed to maximize traction on all types of terrain.e. Axles. Front and rear axles (4 and 5, Figure 1-5) feature wheel end planetary drives designed to allow the vehicleto carry heavy loads. When the vehicle is operated in MODE, all axles become driving axles. When the vehicle isoperated in MODE, 7th gear is unavailable.1-11. ENGINE AIR INTAKE SYSTEMFigure 1-6. Engine Air Intake SystemThe engine air intake system consists of a dry-type air cleaner (1, Figure 1-6), turbocharger (2), and a charge air cooler(3). The turbocharger increases engine horsepower by delivering a higher volume of air to the engine. Engine exhaustgases flow through the turbocharger, causing a turbine wheel to spin. As the turbine wheel spins, a compressor wheelon the opposite end of the turbine wheel shaft spins and draws fresh air through the air cleaner. The compressor wheelcompresses the air and delivers it to the charge air cooler. The air flows through the charge air cooler which cools theair before it is delivered to the engine cylinders. The charge air cooler allows a denser charge of air to be deliveredto the engine, which also aids in increasing engine horsepower.Change 1 1-9
