PRINCIPLES OF OPERATION.
Batteries (Figure 1-28). Two 12 volt batteries are used. Each battery is enclosed in a battery box. One is
mounted at each side of the engine hood. They are connected in series to provide 24 volts of power. Refer to paragraph
1-10 for location.
TRANSMISSION (Figure 1-29). The transmission is attached to the rear of the engine. Engine power enters the
upper (forward and reverse) section of the transmission. It is transferred to the lower (six speeds) planetary section and
then forward into the differential and outward to the final drives. No torque converter is used.
A transmission and differential oil sampling valve is mounted vertically on the transmission oil cooler bonnet. Refer to LO
5-3805-261-12 and TB 43-0210 for oil sampling instructions.
