Description. a. Features and Capabilities. The M917 dump truck body provides the capability of hauling and dumping, or spreading heavy loads of hot asphalt, aggregate, dirt, and similar materials. The M917 vehicle chassis has off-road capabilities therefore providing a wide variety of terrain in which the dump truck can operate. The dump body contains a sealed hydraulic system for raising and lowering the dump bed. The hydraulic system is powered by the vehicle chassis PTO unit. The tailgate can be adjusted for dumping the load or for controlled spreading while the vehicle is moving. b. Major Components. Figure 1-1 shows the location of major dump truck body components you will need to become familiar with to properly operate the M917 dump body. (1) Guide rod. This steel rod, bolted to the cab protector, provides the operator a visual indication of when the bed is down. (2) Dump bed. This is a rectangular shaped steel bed for hauling hot asphalt, aggregate, or various other materials. It incorporates a cab protector as a structurally integral component. Its purpose is to protect the cab. A dog house is provided in the front of the bed in which the top of the hoist cylinder is mounted. (3) Tarpaulin hooks. There are fourteen hooks attached to the dump body for attaching the tarpaulin, five on each side, two in front and two in the back. Change 2 1-0
