1-9. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS.
Frame and Suspension.
The frame consists of two side members and seven cross members bolted together. The frame serves as
a mounting base for the engine, drive train, fire pump, cab, pump body, and hose body. The frame is flexible to prevent
heavy stress on components during travel in rough terrain.
The front bumper is mounted directly to the side frames together with two eyelets for towing purposes, (see
fig. 1-2). Rear towing eyelets are also attached to the frame. The suspension leaf springs are attached to the frame with
shackles and spring pins. The axles and springs are assembled with two U-bolts at each location. Spring action is
dampened with heavy duty shock absorbers.

Cab and Body.
The cab and body consists of three separate assemblies each attached to the frame by means of vibration
absorbing rubber mounts. The cab, pump body, and hose body (see fig. 1-3) are fabricated of aluminum and insulated
against heat and cold. The cab is divided by a fire wall making the front compartment fully enclosed. The front
compartment accommodates the driver and one crewmember. The rear semi-enclosed compartment contains two rear
facing crew seats. All crew seats are equipped with seat belts.
