Correct Answer and Feedback
5.
C.
To give the
towed
vehicle
steering
and
braking
capabilities.
All braking and steering actions are accomplished within
the
transmission.
The
final
drives
connect
the
transmission and the tracks together. If the final drives
are not connected to the transmission, there is no way to
transmit these actions to the tracks to control the
vehicle.
A tow bar provides a positive link between the
towed vehicle and the towing vehicle for control purposes.

6.
D.
Cooling and lubrication.
In addition to transmitting torque and motion, the
continual movement of oil through the converter assembly
provides lubrication and cooling. (page 12, para 7)
7.
C.
Third.
The first, second, and fourth clutches are used to provide
a forward and reverse range.
The only time the third
clutch is used is to provide the third range forward.
(page 18, para 3)
8.
B.
The output pump check valve opens and allows
the
output pump to feed the primary hydraulic circuit.
This normally closed check valve provides an interface
between the main pump and the output pump.
If the main
pump fails for any reason, this check valve reacts by
opening and allowing the output pump to provide pressure
and flow to the main hydraulic circuit. (page 27, para 2)
9.
D.
Direction of rotation of the hydrostatic pump.
The function of the supercharge check valves is to provide
oil to the hydrostatic pump at all time. The direction of
rotation of the hydrostatic pump determines which port will
be pressure and return.
Since the rotation of the pump
determines
which
port
is
pressure
and
return,
the
supercharge
check
valves'
reaction
to
the
rotation
determines which one of them will be open to provide oil to
the pump continuously. (page 59, para 2)
