and is driven by this secondary flywheel. When the clutch pedal in the cockpit is depressed the clutch is released and power flow is interrupted at this point. When the clutch pedal is released the fly-wheel clutch is spring engaged and power flows through the clutch to the transmission. Here various combinations of gears determine the speed and direction of the machine's travel.

From the transmission, power flows through the ring gear and pinion to the differential and from the differential through the final drive pinion and final drive gears and axles to the wheels.

POWER SHIFT TRANSMISSION

The rotating engine flywheel is attached to and drives the generator rotor and secondary flywheel. which is attached to the rear of the rotor. The flexible drive disc of the transmission is at-tached to and driven by this secondary flywheel.

5. Final Drive Pinion

The flexible drive disc drives the torque converter pump. Here the rotation is transferred to the oil in the converter which in turn drives the converter turbine. The converter output shaft carries the rotation to the various planetary range gears and clutches. Here by shifting to the desired range, the rotation is transferred to the trans-mission output shaft, through the output shaft to the output pinion. The output pinion is in mesh with the ring gear on the differential.

The rotation is carried from the output pinion through the ring gear and differential to the final drive pinions and final drive gears to the axles and wheels.

ELECTRICAL SYSTEM

A simple, reliable and efficient electrical system puts the power at the point of use instantly.

When a control switch on the instrument panel is closed, the main switch Un the circuit between the generator and the motor) is

closed and the motor operates. While the motor is operating, the motor brakes are automatically released. As soon as the switch is released, it returns to the off position and the operation ceases and brakes are automatically spring engaged, thereby holding the load.

Electric current is always available when the engine is operat-ing and the generator is excited (d.c. main switch onl. Keep engine operating as near high idle as possible when operating an a.c. elec-tric motor. This assures that maximum efficiency is being obtained.

OPERATING INSTRUCTIONS

The instructions which follow are intended to acquaint the op-erator with the instruments and controls and their proper use in operating the Model D Tournapull and trailing units.

It is imperative that the operator understand the function and operation of each of the instruments and controls. This knowledge is essential for the proper maintenance and safe operation of the machine, which will give longer machine life and less unproduc-tive down time.

STEERING MOTOR WARNING LIGHT - (I) remains on at all times unless the temperature of the steering motor stator exceeds the safe operating range. Should the light go off, allow a short in-terval for the motor to cool and the light to come on again before resuming operation. Should the light continue to go off at short in-tervals, the trouble should be located and corrected.

OIL PRESSURE OVERRIDE SWITCH-(2) eliminates false starts until engine oil pressure has built up enough to permit normal op-eration. Hold switch in only long enough to be assured of adequate engine oil pressure. (This applies to Cummins engines only.) If en-
