PRINCIPLES OF OPERATION.
Hydraulic Oil Cooler (Figure 1-14). Mounted at the upper forward surface of the radiator. Air passing
through the cooler removes heat from the hydraulic system oil before it returns to the hydraulic oil reservoir behind the cab.
Alternator (Figure 1-15). 50 ampere rating. Belt driven by transmission oil pump pulleys. Charges batteries
and supplies current for additional electrical power. A voltage regulator is located behind the end cover.
