5. Optional Equipment
Several items of optional equipment are available for the 6906 Series units. When applicable, information
for optional equipment will be located in Chapter 5.
A. Four-Wheel Trailer (Specification 6906-1)
This is a standard four wheel trailer, used on earlier Series 6906 generator set models, and identified
by Hobart Part No. 408595.
B. Fifth-Wheel Trailer
A trailer with fifth-wheel front running gear is available, with or without batteries and fuel tank. This
trailer with fifth-wheel replaces the previously used four wheel trailer, and reduces greatly the turning
radius when the unit is being towed.
B. Transformer-Rectifier (Specifications 6906-3, 6906-4, 6906-5, and 6906-6)
A transformer-rectifier (T-R) is available for use with Specifications 6906-3 ,6906-4, 6906-5 and 6906-
6 generator sets. This T-R receives 115/200-V, 400-Hz, AC power from the generator and converts it
to a 28.5 V DC output. Additionally, Specifications 6906-5 and 6906-6 may be equipped with a sec-
ond T-R, with rated output of either 28.5V or 112 V.
C. Truck
Trucks with special bodies for mounting the generator set are available. Compartments in the body
are provided for batteries, cable-storage, etc. Trucks available are Ford, Chevrolet, and GMC.
D. Quick Start Kit
(See Section 1-3, Para. 2C)
6. Canopy
A sheet metal enclosure, identified as a canopy (1, Fig. 1), provides protection for the engine, generator
and electrical controls. The canopy is designed to reduce operational noise in the immediate area of the
machine. Four hinged doors on the left side provide easy access for service and maintenance. Two
hinged doors near the front on the right side provide access to the engine compartment. Panel mounted
instruments may be observed through two Plexiglass windows which cover a portion of the control box
and the engine control panel. The lower window is slanted outward at the bottom to provide an opening
for reaching engine controls. A small panel located below the air cleaner covers the dual output terminal
board.
7. Engine, Generator, and Controls Assembly
This assembly is the basic generator set without canopy. It includes all components required to generate
and regulate 400 Hz, 115/200 V, three phase power, and is operable when provided with fuel and 12 V
DC power. The engine-generator assembly is mounted on a welded steel frame. A superstructure, at-
tached to the main frame, provides mounting facilities for the canopy, control box, electrical equipment
and controls.
A. Basic Engine
This generator set is equipped with a 6-cylinder, in-line, turbo-charged John Deere Diesel engine. See
Figure 2 for general specifications, and see Engine Operator’s Handbook in Chapter 6 for more de-
tailed information.
