LOCATION AND DESCRIPTION OF EXTERNAL COMPONENTS (Continued)
ENGINE (14). 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 trailer frame. The engine flywheel is directly connected to the pump with a dry-type flexible coupling.
AIR INLET COMPONENTS (1 5). 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 (1 6). 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
trailer 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.
LIFTING BAIL (17). The lifting bail provides a secure point of attachment for lifting the centrifugal pump unit. The bail is
secured to the trailer frame at the centrifugal pump unit center of gravity.
EXHAUST SYSTEM (18). The exhaust system components vent engine exhaust gases from the exhaust side of the
turbocharger. The components include a spark arrestor, muffler, and the exhaust pipes between the muffler and
turbocharger.
FABRIC COVER (19). The fabric cover fits over the centrifugal pump unit. It protects the components from
environmental conditions when the unit is not in operation. The cover is made of a flame-resistant, vinyl-coated nylon
material with rubber tiedowns that hold it in place.
RETROFIT KIT (not illustrated). When installed, the retrofit kit replaces the automatic speed control with a manual
throttle. The kit includes a mechanical throttle cable and a start/stop circuit breaker. When not installed, the retrofit kit is
stored in the tool box.
