AUXILIARY AUTOMOTIVE SYSTEM
The auxiliary system includes driver controls, personnel heater, bilge pumps, crew ventilation system, and fire
The driver controls regulate the engine, transmission, and steering braking systems of the earner.
The fuel shutoff control is used to stop the supply of fuel to the injectors. To start the engine, the driver must
push in the fuel shutoff control. The throttle linkages are used to control the engine speed. The gear selector
allows the driver to choose the proper gear for the carrier. The steering and braking levers control separate
right and left steering brakes in the control differential. By pulling on the levers, you can slow or stop either
track for steering, or both tracks at once for stopping. A lock button at the top of each lever lets you set and
lock the brakes for parking.
PIVOT STEERING AND BRAKES
Pivot steer brakes are disk brakes and work like the differential brakes but quicker.
The differential consists of three major assemblies. These are the right angle gearbox, stewing unit with brake
shoes, and two output shafts.
Power flow is from the transmission to the right angle gearbox to the steering unit.
When driving straight forward the steering unit delivers equal power to both output shafts. Pressure on either
steering lever slows or stops the right or left brake drum, inside the center steering unit, and reduces the speed
of the right or left output shaft. By slowing down on one side you increase the speed of the other and the earner
will turn in the direction of the applied brake.
