The transmission is a three speed, constant mesh, planetary gear train with hydraulic torque converter and
lockup clutch. It automatically selects the proper gear based on road and load conditions. The transmission
delivers power from the transfer gearcase to the differential.
Major exhaust system parts are the exhaust manifolds, and muffler. The exhaust manifolds carry the exhaust
gases to the muffler. The muffler cuts down engine noise and allows exhaust to escape outside the carrier.
The cooling system cools the engine and transmission. It consists of a fan, fan drive belts, radiator, coolant
pump, auxiliary tank, transmission oil cooler and thermostats. The cooling system contains approximately 14
gallons of liquid coolant. The liquid coolant is pumped by the coolant pump from the radiator and circulated
through the engine and thermostat and back to the radiator where it loses heat to the atmosphere. This
process keeps the engine, transmission, and differential temperature in a safe operation range.
As coolant flows through the engine, it absorbs heat from the engine and transmission. The heated coolant
then flows to the radiator to remove coolant heat. The coolant fan pulls outside air in and through the radiator
to remove heat. The fan is powered by the transfer gearcase.
The radiator auxiliary tank acts as an overflow tank to keep the cooling system from overpressurizing. It also
removes air from the engine coolant.
ENGINE AIR SYSTEM
The engine air system allows air to enter the engine. The air cleaner cleans air that enters the engine. Air is
filtered through a reusable filter element before delivery to the engine. An air filter indicator shows when the
element is clogged and needs cleaning or replacing. After being filtered, the air moves through the air horn and
into the engine cylinders.
