1-9. LOCATION AND DESCRIPTION OF EXTERNAL COMPONENTS (Continued)
FUEL TANK (4). The fuel tank contains a 20-gallon supply of diesel fuel for the engine. The tank is mounted to the rear
third of the skid frame, just below the engine. The tank includes a filler cap, fuel gage, and various fittings for fuel lines.
NOISE SHIELD (5). The noise shield reduces pump and engine noise at the operator's position in front of the control
panel. In addition, the shield reduces vibration of the control panel and supports the front portion of the fabric cover.
The base of the shield is mounted to the front of the skid frame, and to the supports of the control panel.
SUCTION ASSEMBLY (6). This assembly controls the liquid supply to the pump body suction port. The assembly is
secured to the suction port mounting studs at the front of the pump body. It is supported by this connection and support
brackets on the skid frame. The suction assembly consists of a gate valve, a strainer assembly, connective piping, and a
victaulic coupling flange.
SKID ASSEMBLY (7). The skid assembly is a movable mounting platform for the major components of the centrifugal
pump unit. The skid is a welded frame with provisions for mounting the components, runners which incorporate enclosed
forklift pockets, battery and tool boxes, and a 20-gallon engine fuel tank.
TOOL BOX (8). Centrifugal pump unit accessories are stored in the tool box. It is attached to the left side of the skid
frame, in front of the battery box.
PUMP ASSEMBLY (9). The pump assembly uses the turning force of the engine to pump liquid from the suction port to
the discharge port of the pump body. The pump assembly is a single-stage, centrifugal pump which is self priming after
initial filling. The pump body portion of the assembly is mounted to the front portion of the skid frame. The bearing
housing portion of the assembly attaches to the engine bell housing and flywheel.
BATTERY SYSTEM (10). The battery system components supply dc power to the starting motor, control panel, and
electrical system. The components include a battery box, two 12-volt batteries, a charging receptacle, and connecting
cables and wires.
OIL DRAIN ASSEMBLY (11). The oil drain assembly is an extension of the engine oil drain. It makes draining the
engine oil easier. The drain assembly is located below the engine and projects from the rear of the pump assembly.
ENGINE (12). The engine provides turning force to the pump rotor. The engine is a turbocharged, six cylinder, in-line,
diesel engine. It has a standard, continuous output rating of 102 hp at 2400 rpm. The engine is mounted to the rear
portion of the skid frame. The engine flywheel is directly connected to the pump with a dry-type flexible coupling.
AIR INLET COMPONENTS (13). The air inlet components supply filtered air to the inlet of the engine through the
turbocharger. The components include a dry-type air cleaner and air hoses between the air cleaner and turbocharger.
ENGINE COVER ASSEMBLY (14). The engine cover encloses and protects the engine from environmental conditions
during operation. The cover consists of a metal frame; and side, top, and end panels. The frame is attached to the skid
assembly. The cover panels are attached to the frame with hand operated fasteners. The rear panel includes an air
intake duct and filter that provide filtered cooling air to the engine.
