a. The trailer assembly is primarily a welded frame

consisting of two longitudinal channels separated by a

series of angles and channels at both ends. A trailer

stand located at the draw bar end of the trailer is held

in a raised or lowered position by two pins. The draw-

bar can be extended to provide a greater turning clear-

ance with the towing vehicle.

of the trailer frame. The axle assembly consists pri-

marily of the axle, hub assembly, wheel, and tire. The

tool box is mounted on the right side of the trailer. The

trailer assembly provides support for mounting the

pump, engine, fuel tank, suction and discharge assem-

blies, ground rods, and remaining components of the

pumping assembly.
