EQUIPMENT DESCRIPTION AND DATA - (CONTINUED)
LOCATION AND DESCRIPTIONS OF MAJOR COMPONENTS
FRAME, CHASSIS ASSEMBLY
Heavy-duty precision aligned, 1-piece steel tubing and plate welded structure. All frame and body surfaces are
shot blasted, primed, and painted with weather resistant paint. Standard bolts are SAE grade 5, zinc-phosphate
coated to resist corrosion.
CREW PROTECTION SYSTEM (CPS)
A rigid cab structure that provides heating and ventilation, interior lighting, and removable doors. The CPS includes
a windshield with wipers, rear sliding window, heater, fan, and dome light. The doors also have sliding windows.
A radiator system is provided for engine cooling. The radiator is mounted to the engine cradle and is insulated from
vibration. An oil cooler mounted to the front side of the radiator provides transmission cooling.
The ITL Model PS750 Powershift automatic provides one reverse and two forward speed ranges. Forward
and reverse speed ranges are obtained through the use of electrically controlled solenoids and hydraulically
The power from the engine is transmitted to the transmission through a torque converter. The use of the torque
converter has two distinct advantages, one is the converter is essentially a luid drive, there is no direct mechanical
connection. This feature creates smooth and shock free drive eliminating engine stalling and lugging.
An input clutch assembly contains two hydraulically operated clutches; one clutch provides a forward low ratio
drive and the other a forward high ratio drive. A three-position solenoid is energized by the shift lever to direct
pressurized oil to either the forward low or the forward high clutch.
Likewise, when the shift lever is used to select reverse, the three-position solenoid is energized to direct
pressurized oil to reverse clutch.
The transmission park position is achieved by an electric actuator operating a caliper on the brake disc mounted to
the transmission output shaft whenever the shift lever is placed in Park. When the shift lever is moved out of Park
the electric actuator releases this caliper.
An oil pump draws oil through a strainer in the oil pan and circulates the oil through the engine. Before entering
the engine, all the oil from the pump passes through the oil ilter. Surplus oil drains back into the pan. Engine oil
pressure is maintained by a spring-loaded, pressure-relief valve in the oil pump.
The screw-on oil ilter has an internal relief valve to bypass the ilter if the element becomes clogged.
A lift pump draws fuel from the fuel tank through a fuel water separator. This fuel water separator has a manual lift
pump on it. Fuel is delivered through an inline fuel ilter and then a inal ilter mounted on the engine. The fuel
exits the inal fuel ilter and lows to the four injectors.
AIR INTAKE CLEANER
The air cleaner is a dry element type and is located on the left side of the tractor. It prevents dirt and other
foreign materials from entering the engine.
The exhaust system consists of an exhaust manifold, exhaust pipe, mufler, and tail pipe. The exhaust manifold
has large radius curves which permit exhaust gases to leave the cylinders with a minimum of back pressure and
power loss. All parts of the exhaust system are well supported with clamps and hangers.
