LOCATION AND DESCRIPTION OF MAJOR COMPONENTS - Continued
DEAD CRANK SWITCH
The dead crank switch (Figure 1, Sheet 4, Item 21) is located inside the generator housing at the left rear. During
maintenance, the dead crank switch allows the engine to be cranked without starting the engine.
NATO SLAVE RECEPTACLE
The NATO slave receptacle (Figure 1, Sheet 4, Item 22) is located on the left side (front) of the TQG. It is used for
24 Vdc slave starting.
BATTERIES
Four 12 Vdc batteries (Figure 1, Sheet 4, Item 23) located at the front of the generator are connected in series
and parallel. The batteries provide power for EMCP controls, engine starting, and to the NATO slave receptacle.
These batteries can be disconnected with the Battery Disconnect Switch (Figure 1, Sheet 4, Item 24).
WINTERIZATION KIT (ISSUED TO SELECTED UNITS ONLY)
The winterization kit consists of a fuel-fired heater (Figure 1, Sheet 4, Item 25) to heat engine coolant. The kit also
includes resistor heaters located in EMCP. The fuel-fired heater is controlled with the winterization kit control
panel (Figure 1, Sheet 3, Item 20).
STARTER
The engine starter motor (Figure 1, Sheet 5, Item 26) is located on the right rear side of the engine. The electric
starter engages the flywheel mechanically to start the diesel engine.
SKID BASE
The skid base (Figure 1, Sheet 5, Item 27) provides the main structural support for the engine generator set. The
skid base consists primarily of two formed side rails, cross members, mounting pads, fork lift openings, and a
bottom plate. Main cross members complete the primary skid base structure to support the engine and generator
mounting pads and vibration isolators and reinforce the fork lift openings (Figure 1, Sheet 5, Item 28). Four 25,000
lb (11,400 kg) capacity LIFT/TIEDOWN rings (Figure 1, Sheet 5, Item 29) are attached to the skid weldment. In
addition to supporting the engine generator assembly, housing, battery and other components, the skid base
has provisions for engine oil drain (Figure 1, Sheet 5, Item 30), coolant drain (opposite side), a water separator
drain (Figure 1, Sheet 5, Item 31), and fuel tank drain (Figure 1, Sheet 5, Item 32). The skid base also serves as a
support and protective enclosure for the fuel tank.
FUEL TANK
The fuel tank (Figure 1, Sheet 5, Item 33) is a 128 gallon (485L) molded tank located below the diesel engine
between the skid assembly side members.
ENGINE CONTROL MODULE
The engine control module (ECM) (Figure 1, Sheet 5, Item 34) monitors most of the engine sensors and controls
the amount of fuel that is injected by the unit injectors as well as engine timing functions.
