RECEPTACLE

Figure 3.

All lubricating and clutch-applied oil is provided by an engine-driven pump (in the

transmission).

The transmission includes an electrically-controlled power take-off (PTO).

The PTO provides power to a hydraulic pump, which powers the vehicle's hydraulic system.

The hydraulic system operates the self-recovery winch, the material handling crane, the

heavy-duty recovery winch, and the pumping equipment, depending on how the vehicle is

equipped.
