POWER FLOW
SYSTEMS OPERATION
TM 5-3805-263-14&P-2
The basic components of the power train are: the
engine, transmission gears, power shift transmis-
sion, differential, final drives and axles, and the
tandems and wheels. There is no clutch or torque
converter used in this machine.
Power from the engine goes directly to the
upper section of the power shift transmission
which has the forward and reverse direction
clutches. The lower section has the speed clutches.
Four of the five speed clutches are stationary,
while one clutch is a turning clutch. Three clutches
must be engaged at the same time to have power
flow through the transmission.
Power goes from the output flange of the trans-
mission planetary to the pinion gear of the differen-
tial. The differential turns the axles that turn
planetary gears of the final drive.
The sprockets of the final drive are connected to
the wheel spindles with chain.
