SELF-PROPELLED GENERATOR SET, SPEC. NO. 5381A
Power for mobile operation is supplied by the same engine which drives the 400-Hz gen-
erator . The generator rotor is coupled directly to the engine flywheel and actually be-
comes part of the drive train for mobile operation. A single-disc, pressure-plate type
clutch is mounted on a flywheel at the rear of the generator stator. A conventional,
three-speed transmission is mounted directly to the rear of the generator exciter housing.
A short drive ,shaft, with universal joints at each end, transmits power from the trans-
mission to a drop-type reduction gear and rear axle assembly. Power is then transmitted
to the rear drive wheels through a conventional differential and axle shafts. The rear
axle is equipped with shackle-mounted, elliptical, leaf springs.
The front axle is a solid-beam type with pivoting wheel spindles. It is also equipped
with e II iptical , leaf springs.
Steering is mechan ica I, through a worm and roller type steering gear assembly.
Service brakes are four-wheel hydraulic. The parking brake is a mechanical, contract-
ing-band type, mounted at the rear of the transmission. It operates on a drum attached
to the output shaft of the transmission.
All mobile operation controls are conventional mechanical type.
All units are equipped with a single seat mounted on the left side. This design allows
space on the right side of the driver for mounting T-Rs (transformer-rectifiers) when
furnished.
The engine , generator, and electrical controls are protected by a sheet metal housing
assembly identified as a canopy. The canopy is equipped with sliding-folding doors
on both sides for access to the engine and electrical components mounted on the forward
end of the control box. A panel on the left side of the canopy provides access to
terminal boards and equipment on the left side of the control box. A radiator grille
and housing forms the front part of the canopy. This housing has a hinged cover for
access to the radiator cap.
Heavy gauge stee I fenders protect the equipment and occupants against road splash, etc.
A large fue I tank is located in the body on the right side of the vehicle. Four, six-volt
batteries are stored in the body on the left side. A cable storage box is located behind
the seat assembly.
The vehicle is equipped with all necessary driving lights, including headlights, tail
and stop lights, clearance lights, back-up lights, and turn signals.
