LOCATION AND DESCRIPTION OF MAJOR COMPONENTS - Continued
SKID BASE
The skid base (Figure 1, Sheet 5, Item 27) provides the main structural support for the engine and generator. The
skid base consists primarily of two formed side rails, cross members, mounting pads, forklift 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 base frame. 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 66 gallon (250L) 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.
GENERATOR HOUSING
The housing (Figure 1, Sheet 6, Item 35) is fabricated from sheet steel and attaches directly to mating flanges on
the skid base. The housing is thus removable for unscheduled maintenance and engine or generator removal.
Access openings and doors (Figure 1, Sheet 6, Item 36) allow engine, generator, and other component servicing.
Each side of the rear housing has a set of double doors and the large doors at the front of the housing provide
accessibility. The housing structure incorporates acoustic damping foam and internal baffle structures to reduce
engine noise. The rugged design of the housing includes reinforced corners and access openings to meet
transportability, operational, and handling requirements of a mobile military generator set.
TRAILER-MOUNTED CONFIGURATION (PU-807A)
The skid-mounted TQG can be mounted on a model XM1061 E1 5-ton trailer (Figure 1, Sheet 6, Item 37). In this
configuration, the TQG can be towed and positioned as required. In the power unit configuration, the trailer-
mounted TQG has an accessory box (Figure 1, Sheet 6, Item 38) and two fire extinguishers (Figure 1, Sheet 6,
Item 39). The TQG skid is bolted directly to the trailer bed and frame.
