Table 1-4. Description of Major Components, Model US636HCCD-1. Item No. 1 2 3 4 5 6 7 8 1.15 Item Name TURBOCHARGER EXHAUST SYSTEM ROTATING ASSEMBLY SLING/TIE DOWN POINTS AXLE AND WHEEL ASSEMBLY V-BELT GUARD AIR INTAKE SYSTEM FUEL TANK Description and Purpose Driven by the force of the engine exhaust. Compresses intake air to a density up to four times that of atmospheric pressure. This greater amount of dense air allows more fuel to be burned, thereby doubling the engine’s power output. The turbocharger also reduces exhaust emissions and exhaust noise. Exhaust gases are expelled through the exhaust manifold to the turbocharger. The gases are then expelled by the turbocharger through the muffler, exhaust pipes and rain cap. Engine noise is reduced by passing exhaust through the muffler. Rain is kept out by the rain cap. Provides the interface between the diesel engine and the water pump. The pump rotating assembly contains the impeller shaft of the pump which is supported by a single, self-lubricated, permanently sealed, ball bearing. The impeller shaft drives the impeller which causes the pump to transfer water. Tie down points are used to secure the pump assembly to transportation vehicles. The sling load points are hard points used for sling operations. Used to support and transport the pumping assembly. Encloses all V-belts to prevent foreign objects from interfering with operation or personal injury. Covers crankshaft, alternator, and tension pulleys. Maintains a supply of fresh air to each cylinder so that air can be drawn into each cylinder on the intake stroke. The turbocharger draws air through a clean air filter and air intake pipe assembly. The air supply is kept under pressure by the turbocharger to provide additional power from the engine. Stores diesel fuel, used to power diesel engine operation. SECTION III. PRINCIPLES OF OPERATION PUMPING ASSEMBLY OVERVIEW. 1.15.1 General. The 600 GPM pumping assembly is a mobile system that transfers potable water. It is trailer mounted and is towed by a vehicle for short distances. When relocated, the 600 GPM pumping assembly is disconnected from the vehicle and stabilized. When used as a source pump the pumping assembly is connected between the water source and TWDS. When used as a booster pump, the pump disconnected to hose assemblies. When the engine is started, the water flow through the pump is controlled by gate valves. The following paragraphs provide a detailed functional description of the 600 GPM Pumping Assembly. 1-8 TM 10-4320-344-24
